Fluid retention in pregnancy


Pregnancy is a stage of life in which important adaptations take place in the woman's body, due to the great changes that she has to experience to produce a baby. One of the most common is fluid retention, mainly in the last months of pregnancy. It is estimated that up to 80% of pregnant women can suffer from them.

There are many causes that cause pregnant women to accumulate fluids. The hormonal changes that accompany pregnancy, such as increased aldosterone secretion, a change in renin activity, and an increase in sodium reabsorption at the renal level are some of the reasons why it occurs.

The growth of the uterus also compresses the vessels that are responsible for returning the blood from the lower limbs to the heart. The increased pressure produced by said compression is the cause of edema in the legs, feet, anus, vulva ... among others and varicose veins, typical of pregnancy, in addition to favoring the appearance of thromboembolic problems to which the pregnant woman, due to changes that also occur in its coagulation, it is so prone.

Edema in the lower limbs is one of the most typical manifestations of fluid retention in pregnancy. They occur mainly in the feet and ankles, they manifest as swelling in the area. These edema are notably worse when standing for a long time, at room temperature, since the heat favors vasodilation, and worsens the picture.

Those women with twin pregnancies tend to have more problems with fluid retention than those who are expecting a single baby. In addition, the permeability of the blood vessels is modified and the composition of the plasma is also modified, which favors the appearance of said retention.

This tendency to fluid retention can influence the appearance of carpal tunnel in pregnancy, a pathology that causes pain and numbness in the hands and / or wrists.

Although they are considered physiological, it is advisable to go to the emergency room if an exaggerated increase is observed in a short period of time or edema in the face or hands.
