Scientists from the Weizmann Institute in Israel conducted a joint study with scientists from the Max Planck Institute for Psychiatry in Germany and found out that the transferred stress of the fetus during pregnancy can cause compulsive overeating in girls in the future, writes

Stress during pregnancy is harmful for both mother and unborn child - many scientists have already written about this.
But in a new study published in the journal Cell metabolism There are new data on how the intrauterine stress can affect the development of the child in the future. In particular, the study focused on female babies. The transferred intrauterine stress can change the development of the brain and cause infertility in food consumption in a newborn girl in the future. Doctors say that eating disorders are associated with stress experienced in early childhood, such as childhood trauma or complications during childbirth. They also say that perinatal stress also affects the fetus and can lead to various psychiatric and metabolic disorders.
Compulsive overeating is characterized by the fact that a person loses control over his eating habits and begins to consume large amounts of food in a short period of time. However, he does not feel the feeling of hunger.

Such people often suffer from obesity and nervous disorders, as they experience shame, guilt and stress. And it also provokes subsequent bouts of overeating.

The first signals come in, as in most cases, various disorders - in adolescence. And as statistics show, women in 2,5 are more likely to be overeating than men. Scientists insist that the causes of such disorders lie in a combination of genetic, biological, psychological and social factors.

During the study, physicians created a mouse model, which showed that fetal stress and stresses in early childhood increase the risk of developing compulsive overeating about females. A team of scientists manipulated nerve chains in the brain that produce stress hormones such as cortisol. Researchers also focused on the process in which corticorelin (CRF) is involved, which is associated in the human body with appetite suppression, anxiety and the ability to resist inflammation.
Experiments on mice have shown that the introduction of a trigger during the third trimester of the mouse has changed its water balance. After researching the hypothalamus of a newborn mouse, it was found that it contained epigenetic markers in the form of methyl cells.
However, compulsive overeating was discovered only after the mice received a restriction in eating under stress. To do this, they were fed in a certain mode. Once on the 3 of the day, they were given 2 hours of time so that subjects could consume food in unlimited quantities. Rodents ate a lot of food and at the same time ate very quickly. Another group of rodents, which was grown and reared in the same conditions, but without the use of stress - showed normal eating behavior.
Similar behavior is demonstrated by teenage girls, who first limit themselves to eating, and then overeat on food rich in carbohydrates and saturated fats. So, in addition to intrauterine stress on compulsive overeating, you can provoke the body, putting him on the wrong diet.
And more tips from doctors: do not be nervous during pregnancy and take care of yourself and your baby from stress.
