Diagnosis and treatment of constipation in women during pregnancy

Constipation during pregnancy is the most common complaint that women make at the doctor’s appointment. Two-thirds of pregnant women have difficulty emptying the bowels during gestation, and one in three also has a problem in the postpartum period.

During gestation, constipation can negatively affect a woman’s condition, as well as adversely affect the general condition of the uterine muscles: she may be in a state of increased tone, which, ultimately, will lead to premature contractions.

Whether constipation is dangerous during pregnancy depends on how often the problem occurs and whether it affects the general condition of the mother and fetus. In order to prevent dangerous complications, the pathology must be eliminated by passing a comprehensive examination, analyzing the diet, physical activity and other factors provoking constipation (the scientific name for constipation).

Causes of the problem

Constipation in pregnant women can occur at the beginning of the term, and almost before the birth itself, starting from 32 weeks, including the prenatal period – at 38-40 weeks of pregnancy.

The causes of delayed digestion and bowel movement can be various and depend on the period of gestation. It is necessary to consider in more detail the provoking factors at different times.

Early dates

At the very beginning of pregnancy, at 3-4 weeks, there is a sharp restructuring of the female body. Many problems are provoked by the woman herself, violating the regimen recommended by the doctor.

The most common causes of constipation in the early stages:

  • Hormonal imbalance  is the most common cause of bowel dysfunction. In the first months, the body begins to actively prepare for the subsequent bearing of the fetus, the production of progesterone increases significantly. As a result, the tone of the muscles of the pelvis decreases to better fix the fetal egg. This property has the opposite side – the digestive tract slows down noticeably, and intestinal dysfunction leads to constipation during pregnancy.
  • Improper nutrition  – constipation in pregnant women occurs as a result of insufficient intake of fiber and fluid. A woman limits the amount of water, vegetables and fruits, in order to avoid swelling, thereby depriving the intestines of the ability to work fully.
  • Calcium and iron preparations  – these drugs are prescribed in the early stages to avoid anemia and brittle bones, as well as for proper development of the fetus. These medicines have a side effect – a fixing property, as a result of which constipation begins.

The listed reasons can affect digestion not only at the beginning of bearing the fetus, but also provoke problems up to 37-40 weeks of pregnancy.

Causes of Late Digestion Problems

From the second half of pregnancy until the very birth, a few more problems are added to this list:

  • Mobility restriction  – as the fetus and the pregnant woman’s body weight grow, her physical activity decreases. It becomes harder for a woman to walk and do housework; as a result, constipation at 40 weeks of gestation becomes a frequent occurrence.
  • Fetal prolapse before delivery  – constipation at 39 weeks of gestation occurs when the baby’s head drops and presses on the intestinal muscles.
  • Changing the emotional background  – many expectant mothers are very worried before the birth, therefore, constipation at 38–40 weeks occurs due to excitement and fear.
  • Diseases of the intestines and anus  – constipation at 37 weeks of gestation, including the period before delivery, occurs due to regular digestive problems, hard and dry feces. As a result – anal fissures, hemorrhoids and repeated constipation.

To determine the causes of intestinal dysfunction, you need to contact your doctor. The doctor will be able to study the medical history, assess the medical history and health status of the pregnant woman, identify provoking factors and give recommendations on the treatment of the problem.

Are constipation dangerous?

Women who first encounter a digestive problem often ask doctors if constipation is dangerous during pregnancy. Possible consequences may depend on the gestational age, on the woman’s lifestyle, her nutrition and related diseases. Risks vary at different times and can only be determined by a specialist who observes a woman.

Dangers of early pregnancy

What is the danger of constipation during pregnancy in the early

timing? Doctors associate possible pathologies of fetal development precisely with the intake of harmful substances to the child through the mother’s gastrointestinal tract. When a pregnant woman does not empty her colon for a long time, accumulated toxins enter the bloodstream and into the baby’s body through the placenta.

Since the laying of organs and systems of the baby takes place precisely in the first months, during this period the future mother needs to minimize the risk of poisoning and colds.

In addition to the risk of fetal intoxication, there is a risk of a miscarriage due to frequent abdominal pain due to regular digestive problems. Severity can occur not only in the lower abdomen, but also in the lower back. Stresses and feelings join these factors, and constipation becomes even more dangerous.

Late Risks

Constipation at 37–40 weeks of gestation can be dangerous with severe straining during a bowel movement. The tone of the uterus increases with excessive load, which can cause premature onset of contractions. Read more about how contractions begin before childbirth →

Impaired intestinal function can also provoke the development of inflammation of the genitals, thrush and colpitis. And these pathologies in the last weeks of pregnancy are undesirable, since the fetus can get infected during passage through the birth canal.

Regular constipation at 39–40 weeks of gestation increases the risk of gestosis – late toxicosis. Nausea, an increase in blood pressure and swelling join the pains in the abdomen, despite the small flow of fluid into the body.

Does constipation affect pregnancy, many women in the position ask. The answer of the doctors is unequivocal – yes, and in order to avoid negative consequences, you need to seek qualified help in time.
