Each lady has her own characteristics of premenstrual syndrome, which depend on the hormonal background, emotional mood, previous illnesses and age. Often the question arises as to why the stomach is inflated before menstruation.
It is necessary to remember what hormones affect the condition of a woman during the menstrual cycle. It is an estrogen that improves mood, improves well-being and helps the egg to mature. And also progestogens - this is mainly progesterone, which more than others affects why the stomach is inflated before menstruation. Initially, the level of estrogen rises, and then drops quite sharply, and a woman can react with a deterioration in her emotional state, aggressiveness and irritability. In addition, the skin becomes fatter, rashes appear, the general level of immune defense may decrease.
On the day the egg is released, the premenstrual phase begins, in which all undesirable changes occur, since the level of gestagens rises. Among other things, it is possible to increase body weight, increase sensitivity and swelling of the mammary glands, constipation, before menstruation, the stomach is inflated. Flatulence and heaviness in the lower abdomen, pulling and painful sensations help to suspect the onset of "these days."

The complex of processes that determine why the stomach is inflated before menstruation includes the effect of progesterone on the digestive tract, secretion of gastric juice. It reduces the secretion of bile, can reduce intestinal motility, and even minor errors in nutrition, and even more so the exacerbation of chronic pathologies, can lead to constipation, flatulence and bloating. Knowing these features of your body, try these days to exclude legumes, easily digestible carbohydrates, including grapes, juices and sugar. This will significantly reduce discomfort. Enrich your diet with vitamins, if you are concerned about constipation, try to eat vegetables.

But this does not end the effect of hormones. Other possible factors why the stomach is inflated before menstruation is the preparation of the uterus for the adoption of the egg, its swelling and increased blood supply. The uterus has a complex muscle structure and is relaxed more in the phase of the cycle called luteal. Thus, nature ensures the preservation of the egg, reduces the frequency of miscarriages at such an early date. Progesterone has such an effect on metabolic processes that it retains water in the body, leading to its delay in the abdominal cavity.
It is important to understand why the stomach is inflated before menstruation. So you can quickly calm down and improve well-being, increase vitality. But do not forget: if severe or even acute pains in the side and lower abdomen begin to disturb, then appendicitis and ovulatory pain with ovarian apoplexy must be excluded . In this case, bloating and irritation of the peritoneum are also possible, and an ultrasound examination reveals fluid in the pelvic cavity.
