Why does the ovum begin to detach and what to do? Why does the uterus reject the embryo? Preservation of pregnancy during abruption of the ovum Causes of fetal rejection in the early stages

Unfortunately, the sad outcome of pregnancy does not always depend on the woman. As a rule, the primary role is played by the reaction of her body to the “new resident”. This is how experts most often explain detachment of the ovum. Currently, many representatives of the fair half have to hear such a diagnosis. This definition should not be confused with the so-called low-attached fertilized egg. The thing is that these are two completely different concepts. It is important to note that the latter diagnosis still suggests a greater chance of survival for the baby inside the womb.

general information

Treatment usually lasts at least one week. However, even after discharge, the expectant mother should be under constant medical supervision. At this time, it is better to limit physical activity, stay in bed, and try to get more rest.

Consequences

According to experts, timely and competent treatment makes it possible to give birth to a healthy baby. Unfortunately, most often miscarriage and detachment of the ovum become inseparable concepts, since the baby in the womb does not have normal, constant nutrition, and as a result, placental insufficiency develops. In this kind of situation, the woman, together with the doctor, decides on further pregnancy. There can only be two options here - either save the fruit or clean it.

Conclusion

According to available statistics, recently detachment of the ovum, ultrasound photos of which can be found in medical journals and books on gynecology, has become quite common. Some explain this fact by poor ecology, frequent stress, and unhealthy diet. Others see the reasons in the abnormal structure of the uterus. In any case, every woman should understand that the successful outcome of her pregnancy depends on a number of factors that only she can influence.

The first trimester is the time when the risk of complications is greatest. Detachment of the ovum in early pregnancy is a dangerous condition that can lead to the death of the embryo. The main cause of the pathology is genetic abnormalities of the embryo. Symptoms in the form of nagging pain and bleeding may be a sign of detachment and require immediate medical attention.

The concept of detachment of the ovum and its possible consequences

The fertilized egg is a rounded formation, inside of which there is an embryo and a yolk sac, an organ that provides it with the necessary nutrients. The internal contents are protected by a water membrane, the amnion. The chorion is the outer layer that directly borders the wall of the uterus. At a later date, the placenta is formed from it.


Sometimes, under the influence of unfavorable factors, the fertilized egg begins to spontaneously peel off from the uterine mucosa. This phenomenon is called detachment of the ovum and is considered the initial stage of miscarriage. Due to the rupture of blood vessels, blood accumulates at the site of detachment and a hematoma occurs.

A small detachment, provided that the bruising gradually decreases, is not dangerous for the development of the fetus, but requires treatment and constant monitoring, since there is a risk of relapse. A woman who has a partial detachment is admitted to a hospital to prevent spontaneous abortion.

The most dangerous consequences occur when the size of the bruise reaches 40% of the gestational sac. It is very difficult to prevent miscarriage in this case, and the pathology can cause undesirable consequences for the fetus. Complete detachment is characterized by the departure of the embryo from the wall of the uterus and its death. The organ becomes toned, and the process of fetal rejection begins.


Causes of abruption in early gestation

It is impossible to find out what exactly caused the detachment in the early stages in a particular case. In 4 out of 5 cases, the cause of the pathology is chromosomal abnormalities of the embryo. Other provoking factors:

  • hormonal imbalance (lack of progesterone);
  • harmful working conditions;
  • hypertonic disease;
  • developmental disorders of the embryo or placenta;
  • Rhesus conflict;
  • history of artificial termination of pregnancy;
  • smoking, drug and alcohol abuse;
  • infectious diseases;
  • diseases, structural abnormalities of the reproductive organs;
  • neuropsychic and physical overload;
  • unfavorable external factors;
  • age over 35 years.


Associated symptoms

In some women, the onset of abruption of the ovum is not accompanied by any symptoms. As a rule, this happens in cases where the size of the hematoma formed at the site of the tear is very small and does not exceed a few millimeters. Often the detachment makes itself felt with nagging or cramping pain, radiating to the back, and bloody discharge. Their color can vary from cream to bright red. The latter are a dangerous symptom indicating an ongoing miscarriage.

The condition requires immediate medical attention and hospitalization. An unfavorable accompanying symptom is uterine hypertonicity. The contractility of the muscle layer of the organ increases, which can lead to spontaneous abortion. A decrease in basal body temperature below 37°C also indicates pathologies: detachment of the ovum and the threat of miscarriage, regressing pregnancy (more details in the article:). Indirect symptoms also include a decrease in the level of hCG in the blood.

Diagnostic tests

The earlier diagnosis and treatment are carried out, the more favorable the prognosis. If you have suspicious symptoms, you should immediately see a specialist. When a pregnant patient complains of nagging pain or uncharacteristic discharge, the doctor prescribes diagnostic measures to identify the cause of the pathology. First of all, the woman is sent for an ultrasound.

The detachment is visualized as an anechoic structure (not reflecting ultrasound) around the ovum. A change in its shape from round to oval when a hematoma is detected indicates a threat of miscarriage.

Other diagnostic tests:

  • Clinical blood and urine tests. Helps identify the presence of inflammatory processes in the body.
  • Coagulogram. Allows you to identify blood clotting disorders, incl. thrombosis.
  • Blood test for hormones. It is necessary to identify a deficiency or excess of hormones that affect pregnancy (progesterone, human chorionic gonadotropin, androgen metabolic products).
  • Gynecological smear. Helps identify the presence of pathogenic microflora.

Early treatment tactics

Detection of detachment of the ovum is the basis for hospitalization of the pregnant woman. A woman with a threat of miscarriage must remain completely at rest, excluding any physical activity and intimate contact. Even walking can cause harm - vibration and tension in the abdominal wall can cause hypertonicity of the uterus, which aggravates the situation. To avoid complications, bed rest is recommended for the pregnant woman. To improve blood flow from the pelvic area, it is recommended to place a pillow under the buttocks. A woman needs good sleep and a calm environment. It is useful to listen to pleasant music and read books.


Even disturbances in the functioning of the intestines can provoke deterioration, so a pregnant woman must adhere to a diet. Products that can cause increased gas formation are excluded: carbonated drinks, legumes, white cabbage, grapes, mushrooms, apples, milk. Strong tea and coffee, persimmons, chocolate, pastries (cause stool consolidation), as well as prunes, tomatoes, melon and apricots (weaken) are not recommended.

To provide essential nutrients, vitamins and minerals, you need to eat plenty of vegetables and fruits (except prohibited ones). The diet should include fish, meat, herbs, nuts and dairy products. Healthy drinks include compotes, fruit drinks, and rosehip decoction.

Detachment of the ovum requires medical treatment, which includes taking the following medications:

  • Utrozhestan and Duphaston. Medicines contain progesterone, a hormone that is responsible for maintaining pregnancy (we recommend reading:). It is he who suppresses the contractile activity of the uterus and prevents the fetus from being rejected. The drugs reduce the tone of the muscle organ, preventing miscarriage.
  • No-shpy, Drotaverina, Papaverina. They have an antispasmodic effect and relax the uterine muscles.
  • Motherwort, valerian. Used as a sedative.
  • Dicinona, Vikasola. They belong to hemostatics - drugs that are used to stop bleeding. They increase blood clotting and strengthen vascular walls.
  • Vitamins. Necessary for the prevention of fetal development disorders.


Preventive measures to prevent pathology

Prevention of pathology must begin at the stage of pregnancy planning. You can reduce the risk of rejection of the fertilized egg if you eliminate bad habits, start taking folic acid, and perform routine vaccinations at least 3 months before pregnancy. It is necessary to be examined for the presence of inflammatory diseases and sexually transmitted infections. Detected pathologies should be completely cured.

The risk of detachment of the ovum during early pregnancy can be reduced if:

  • eliminate smoking, alcohol and drug use;
  • if you suspect pregnancy, contact a gynecologist as soon as possible and register;
  • avoid sudden changes in situation, climate, time zone;
  • any medications should be taken only as prescribed by a doctor;
  • reduce physical activity, exclude traumatic sports;
  • get enough sleep, walk a lot;
  • follow the principles of a healthy diet, do not eat fast food, foods with harmful additives, refuse weight loss diets;
  • stay physically active - walk, swim, do yoga, special gymnastics for pregnant women.

The beginning of pregnancy is the most dangerous period. The largest number of miscarriages occur in the first months. This means that expectant mothers need to start taking care of themselves from the very beginning of pregnancy.

In contact with

The most common type of miscarriage is abruption of the ovum in the early stages. The fertilized egg is detached from the uterus, and a hematoma begins to form near the fertilized egg due to vascular injury. If the hematoma continues to grow, complete detachment of the fertilized egg and its subsequent death will occur. If you do not pay due attention to the body’s signals, then in most cases the consequence of detachment of the ovum will be the death of the fetus. However, timely treatment can completely prevent this process.

According to doctors, this situation is of a purely individual nature. In one woman, rejection may occur due to nervous strain, while the cause of detachment in another will be the presence of bad habits. At the moment it is impossible to determine the exact reason why such a deviation occurs. But the doctors made up list of factors that can influence the development of the fertilized egg:

  • Deviations in the functioning of hormones (lack of progesterone);
  • Presence of stressful situations;
  • Exceeding the norms of physical activity:
  • Emotional abnormalities;
  • Various gynecological pathologies;
  • Presence of tumors;
  • Presence of viral or infectious diseases;
  • Conflict of Rh factor between mother and fetus;
  • Deviations in child development;
  • Having a woman in the past.

These are the most common causes that cause this disease. This can even happen due to the high tone of the uterine walls. That is why at the beginning of pregnancy you should try to avoid stressful situations, as well as exceeding the permissible level of physical activity.

Unfortunately, it is very difficult to calculate the beginning of a detachment; the problem can happen to absolutely any pregnant woman. Therefore, if any deviations from the norm appear, the pregnant woman must urgently undergo examination.

The most common symptom of abruption of the ovum is the presence. When detachment begins, the blood will have a coffee or ichor color. In this case, you must immediately go to the doctor. If they appear, it means that the resulting hematoma has already begun to resolve. However, this is not a reason to lose vigilance; the possibility of re-detachment cannot be ruled out.

If the color of the released blood begins to acquire a scarlet tint, then this serves as a signal of the onset of a miscarriage and requires immediate hospitalization.

It is worth mentioning that it is widely believed that in the early stages of pregnancy the fertilized egg undergoes so-called natural selection. And if the fetus is strong and has no developmental defects, then it will survive without outside help. Therefore, some women in this case prefer to refuse conservation and medical help. It is worth knowing that such stories have no scientific basis, and egg detachment is usually followed by termination of pregnancy.

Also, sharp discomfort in the lower abdomen and lower back, whose symptoms resemble menstrual pain, may also indicate the onset of this deviation; sensations of increased tone in the uterus are also possible: at the moment of embryo rejection, its contraction occurs, which provokes fetal rejection.

The presence of all these signs will allow even an inexperienced doctor to begin to suspect that the pregnant woman has experienced egg rejection. The presence and size of a detachment of the ovum can be accurately determined only by ultrasound. The devices currently available make it possible to see the beginning of the process, starting from the first days of pregnancy.

Partial detachment of the ovum in the early stages

If the ovum is detached, the prognosis for subsequent miscarriage or continued pregnancy can only be made depending on the stage of development of the pathology. If the detachment becomes more than 40% of the size of the fetus, then there is a great threat to the further development of the child. As a rule, with timely diagnosis, the development of a hematoma formed due to detachment is minimal and can still be treated. In this case, the pregnant woman is given a diagnosis that sounds like partial detachment of the ovum. Doctors will prescribe a comprehensive treatment that will help stabilize blood circulation and stop the subsequent development of pathology. In the case of partial detachment, the risk of miscarriage, if you follow all the recommendations of specialists, is close to a minimum.

This phenomenon can happen repeatedly. When a diagnosis is made, hospitalization is mandatory, as Doctors will be able to provide a full range of measures aimed at maintaining pregnancy:

  • Physical and emotional peace;
  • Taking medications that will help nourish the embryo in the uterus;
  • Administration of medications to stop bleeding;
  • Vitamin therapy;
  • Treatment with sedatives.

Although in any case the decision remains with the woman and the hospital can be refused, this does not eliminate the need to constantly be monitored by the attending physician. This will help avoid the possibility of miscarriage.

As noted above, one of the methods of treating detachment of the ovum is to ensure the woman’s rest.

During this period, it is recommended to follow to avoid unnecessary intestinal tension. It is necessary to avoid the formation of gases and not to abuse tonic drinks. Also, with this diagnosis, the expectant mother should exclude emotional shocks and sexual intercourse from her daily life.

In addition to these simple recommendations, it is also necessary to take medications. Only a qualified specialist can prescribe them. Even those who avoid taking medications must be clearly aware that without their help it is unlikely that they will be able to maintain a pregnancy. In case of detachment of the ovum at an early stage of pregnancy, it is necessary to have on hand hemostatic drugs (such as Etamzipat), antispasmodics (for example, No-shpa), sedatives (among them, you can take Valerian Extract) and hormonal drugs (Duphaston, Utrozhestan). It is also recommended to take additional vitamins. They are often prescribed at the stage of pregnancy planning, however, if a woman has avoided taking them, then in case of such a deviation, preparations containing vitamin E and multivitamin complexes are recommended.

On average, treatment lasts approximately 14 days, but still this time is purely individual. If the pregnant woman carefully follows all the recommendations, recovery may occur faster. It is also necessary to know that the possibility of recurrence of detachment of the ovum exists until the placenta is completely created in the body.

Even after a completely cured detachment of the ovum, until the end of pregnancy, a woman must be constantly monitored by a doctor and follow all his instructions in order to avoid the development of pathologies in the fetus.

Conclusion

If you believe the available statistics, this problem has recently become widespread. Some doctors attribute this to environmental degradation, as well as unhealthy diets. Others attribute this to abnormalities in the structure of the uterus. Regardless of everything, any expectant mother should realize that the end of her pregnancy depends on reasons that only she herself can influence.

Is there a threat? What do experienced mothers think about this:

In contact with

In the initial stages, pregnancy is very susceptible to possible risks. It is in the first weeks that miscarriages most often occur, therefore, as soon as a woman finds out that she is expecting a baby, it is important for her to begin to constantly monitor her well-being. Very often, spontaneous abortion in the early stages of pregnancy can be provoked by detachment of the ovum. Read on to learn about the features of this pathology, as well as how to prevent its occurrence.

A fertilized egg is an egg that is fertilized by a sperm and attaches to the walls of the uterus. In other words, the fertilized egg is the primary environment in which the embryo resides at the very beginning of its development.

Also, the fertilized egg is the first structure distinguished by ultrasound and helps confirm the presence of pregnancy. It has the shape of an oval or circle and increases in size over time.

Around the fifth week, the presence of a yolk sac is clearly visible inside the fertilized egg. Its appearance indicates the normal course of pregnancy and means that the embryo has enough all the necessary substances. Based on the diameter of the fertilized egg, it seems possible to establish the exact term of pregnancy, as well as its possible violations (the doctor evaluates the shape and, thanks to the information received, identifies the state of uterine tone).

What happens when the fertilized egg detaches?

The medical term “detachment” refers to two types of conditions: critical (occurring in the middle and end of pregnancy) and direct detachment of the fertilized egg (typical of the initial stages). The latter option can be caused by various injuries, as well as toxicosis.

Establishing such a diagnosis in the early stages of pregnancy is a very alarming signal and can act as a harbinger of miscarriage. Fortunately, this phenomenon occurs quite infrequently (only 0.5 to 1.7 percent of all pregnancies).

Detachment of the ovum can be mild, moderate or severe. In the case of the middle stage, there is severe pain in the lower abdomen, the uterus tenses, and bleeding is characteristic.

In the severe stage of detachment (a critical condition), dizziness, nausea with vomiting, increased heart rate are characteristic, the patient may lose consciousness, the fetus lacks oxygen, the heart rhythm is disturbed, typically the presence of uterine asymmetry and hypertonicity, bleeding (can be external and internal).

Important! If a pregnant woman experiences signs indicating possible detachment of the fertilized egg, she should immediately go to the hospital for medical help. In mild to moderate severity, you can still cope with this condition with the help of special medications.

Now let's look in more detail at the detachment that occurs in the early stages. First, let's give some anatomical data. So, the uterus is a muscular organ that is characterized by periodic contractions (mostly insignificant). When pregnancy occurs, the fertilized egg, as already mentioned above, is attached to the uterine cavity, where the process of its further development occurs.

At the same time, the formation of the placenta begins, which at the beginning of pregnancy is called chorion. The chorion is a villous membrane of the embryo that covers the entire surface of the fertilized egg. The embryo can penetrate into the uterine mucosa thanks to the villi.

The chorion occupies a very important place in the process of fetal development, because it is through it that the embryo can receive the necessary nutrients, as well as oxygen. Metabolic products leave the baby for the mother along with carbon dioxide. Of course, it is very important that the placenta develops normally, because it is the one that can replace the lungs, organs of the gastrointestinal tract, skin and kidneys at the same time for the embryo. The formation of a full-fledged placenta occurs at the end of the 1st month of pregnancy.

At the same time, characteristic changes are observed in the uterus; chorionic villi grow even more. As mentioned above, the uterus periodically contracts. But this applies only to it, the placenta does not have such a function, which is why, in the case of strong contractions of the uterus in the initial stages of pregnancy, partial or even complete detachment of the fertilized egg can occur. There are cases when this pathological process occurred due to poor blood supply or the peculiarities of the immune reactions of the body of a pregnant woman.

Causes of this pathology

Why can a normally developing fertilized egg begin to be rejected? It is quite difficult to answer this question. A whole set of factors can lead to such a pathological condition, the following stand out among them:

  • the presence of hormonal disorders;
  • abortions previously performed by the woman;
  • presence of disorders in the reproductive sphere;
  • the presence of various formations;
  • inflammatory phenomena occurring in the pelvic organs;
  • features of the anatomy of a woman’s gynecological organs;
  • infections and viruses that a pregnant woman has become infected with;
  • presence of sexually transmitted diseases;
  • presence of arterial hypertension;
  • various negative environmental factors to which pregnant women were exposed;
  • presence of unhealthy habits (smoking, drinking alcohol, drugs);
  • physical overload;
  • significant emotional distress;
  • the presence of genetic pathologies;
  • Rh conflict between mother and fetus;
  • abnormal development of the embryo or placenta.

Despite such an extensive list of factors that can provoke detachment, the most important of them is progesterone deficiency. With it, the female body does not produce enough progesterone, but it is this hormone that is responsible for the normal process of bearing a baby.

Symptoms of this condition

It is rational to talk about detachment when the process of premature rejection of the fertilized egg from the uterus has begun. This is already a real threat to the life of the embryo. The embryo is not able to exist outside the uterine cavity, so complete detachment will invariably provoke its death and end in miscarriage. In fact, detachment is the very first stage of spontaneous abortion.

Along with the detachment of the chorion, the vessels begin to rupture, due to which it penetrated into the uterus, and a hematoma forms in this area. This will be the very first symptom of detachment, which is detected on ultrasound diagnostics. In the case of partial or not very pronounced detachment, a hematoma may be the only manifestation of this pathological condition.

But for the most part, women are able to independently identify the pathology by deteriorating general health and the appearance of blood discharge from the vagina.

Blood discharge is a typical symptom of incipient detachment. The presence of brown dried blood confirms the fact that the formation of the hematoma occurred earlier, and the discharge represents its contents being expelled.

In the case when ichor appears from the genital tract, the tear begins to “overgrow”, but this in no way means that you need to do nothing! On the contrary, it is important to consult a doctor who will monitor your condition.

Bright red discharge is a critical sign of an incipient miscarriage and requires immediate calling an ambulance and hospitalization of the woman. In addition, you should be wary if you notice the appearance of cramping or nagging pain in the lower abdomen or lower back (which are very similar in nature to menstruation), and you also feel that the uterus has become hard: due to hypertonicity, it spasms and rejection begins fetus This process can feel like a hardening of the lower abdomen.

How is detachment treated?

If the diagnosis is confirmed, the woman must be hospitalized. The treatment process for this condition takes place only in a hospital setting, under the careful supervision of doctors. Of course, you have the right to refuse hospitalization and insist on treatment at home, but in this case, doctors will not give you a guarantee that such a condition will not recur and will then result in a miscarriage.

The most important point that must be observed in the event of detachment of the fertilized egg is a state of absolute rest. Not just physical activity is prohibited, but even ordinary walking (even light walking contributes to an increase in intra-abdominal pressure and, as a result, the appearance of uterine hypertonicity, which will accelerate the process of detachment).

It is important to completely relax the muscles of the abdominal wall, and this state can only be achieved in a supine position. If a woman begins to perform even minimal actions, the abdominal wall will tense.

Doctors often advise placing a special cushion or pillow under the buttock area. It promotes blood flow from the pelvis. With increased intestinal motility, there is a risk of repeated detachment, so the woman should adhere to a special diet. It is important to avoid products that have a laxative effect, as well as fastening and gas-forming properties. Also eliminate tea and coffee from your diet.

Of course, in such a situation you will have to refuse intimacy, while during the normal course of pregnancy sex is permitted. It is important not only to eliminate physical risk factors, but also to monitor your psycho-emotional state. Eliminate any stressful situations and possible worries.

A specialist can prescribe medications that help maintain pregnancy. Among them:

  • antispasmodics (use No-shpa, Papaverine, Magne B6);
  • hemostatic drugs (for example, Etamzilat);
  • sedatives (usually valerian);
  • hormonal agents (Duphaston, Utrozhestan);
  • vitamins (usually folic acid and vitamin E); other medications.

Of course, only the doctor is involved in the selection of the necessary funds, as well as their dosage. Avoid any attempts at self-medication, as they can cause great harm, especially in this situation.

The duration of treatment is determined purely on an individual basis. In most cases, treatment lasts about 14 days. This indicator directly depends on how clearly the woman follows all the doctor’s instructions. Therefore, if you want to leave the hospital as soon as possible, strictly adhere to all appointments and instructions.

If a pregnant woman encounters a phenomenon such as detachment at the initial stage of an “interesting situation,” she will have to be constantly checked by a doctor in the future to prevent the situation from reoccurring. Remember that routine examinations are not a whim, but a necessity. Gynecologists believe that if the process of placenta formation has not completed, the risks of relapse remain extremely high.

Possible risks

Do not forget that with partial detachment of the ovum there is a probable threat of miscarriage, and in the case of complete detachment, a spontaneous abortion has already occurred. Since very often this pathological process does not make itself felt and is detected exclusively by ultrasound, you need to be systematically examined and monitor your health.

At the initial stage of abruption, even if there is minor bleeding, it is still possible to maintain pregnancy if you go to the hospital in time.

It is important, as soon as you notice the first manifestations of detachment, to take a horizontal position and under no circumstances start taking any medications on your own. The use of medications can only “blur” the clinical picture and significantly complicate the process of diagnosis and subsequent treatment of the pathology.

Preventive measures

The first thing a young couple planning to have a child should start with is planning for conception. Before this, it is recommended to conduct a full examination of the health status of both the expectant mother and father. This will help identify possible pathologies that may negatively affect the condition of the fetus in the future.

Particular attention is paid to inflammatory processes - before becoming pregnant, it is important to make sure that you are completely healthy. If the examination results show the presence of any pathologies, be sure to undergo the necessary treatment. Of course, the doctor should prescribe it, not you yourself.

When the “preparatory” stage is left behind and you see two long-awaited lines on the test, begin to carefully monitor your health. Eliminate any bad habits, stop taking medications, and reduce physical activity. Stress is one of the main enemies of the fetus; it is extremely undesirable for the expectant mother to experience severe emotional turmoil. The only exception is positive emotions, but they also must be dosed.

Healthy and adequate sleep, proper balanced nutrition, moderate walks in the fresh air, monitoring blood pressure, and avoiding possible injuries are important.

If you adhere to all these rules, do not break them and regularly see a doctor, you can protect yourself from such an unpleasant phenomenon as detachment of the fertilized egg. It is much easier to prevent any pathology than to treat it, and this condition is by no means an exception to the rule.
