If you want to find out more about why do pregnant women vomit, you should know that the exact cause of the problem isn’t clear yet.
The specialists believe that it has something to do with the hormone levels. These fluctuate, affecting the contractions of the muscles of the stomach and the intestines, causing vomiting.
The hormones that seem to be connected to vomiting include hCG, progesterone and estrogen. The abnormal levels of the thyroid hormones may also have a word to say. Nonetheless the relationship is still unclear.
According to some of the studies the symptom gets worse when the blood sugar level drops.
The researchers have found that the women who get nausea because of contraception pills, motion sickness or migraines are more likely to be affected by nausea and vomiting during their pregnancy.
In the same time the women with a family history of hyperemesis gravidarum are also more likely to be affected by vomiting during pregnancy.
Researchers believe that the elevated levels of hCG or some of its components may induce vomiting. Another hormone that we have to think about is serotonin.
This is a chemical of the brain that affects the central nervous system and also the gastrointestinal tract.
When women are pregnant, food goes through the gastrointestinal tract more slowly and this could also contribute to vomiting.
Some of the specialists believe that vomiting is a psychological reaction of women. This may be caused by the fact that there are a lot of changes going on and the body of women is somehow bothered by these changes. If this is the case, women require some counseling.
Naturally when it comes to vomiting while being pregnant, this is a controversial theory. Even more, some specialists don’t accept it at all.
