Causes of Vomiting During Pregnancy

Here are some of the causes of vomiting in pregnancy:

Human Chorionic Gonadotropin:

An elevation in the hormone human chorionic gonadotropin(HCG) plays a vital role in inducing vomiting. Serotonin is another chemical present in the brain that affects the central nervous system and the gastrointestinal system as well. During pregnancy, the upper gastrointestinal tract is slowed down, which contributes to nausea and vomiting.

Gastrointestinal Bacteria:

Helicobacter pylorus lives in the intestinal tract that causes the development of peptic ulcers. This bacterium is found in greater percentage among all the pregnant women. It is found in large amounts in women suffering from hyperemesis gravidarum. Antibiotics are used to treat this condition.

Oestrogen:

This hormone that rises rapidly in the first trimester is another cause for vomiting. There are many other hormones like progesterone that also cause vomiting.

Sensitive to Smell:

Certain smell or odours can trigger the gag reflex. This can result in vomiting.

Tricky Stomach:

Some of the gastrointestinal tracts are sensitive to some of the changes that occur in the first trimester like the growing uterus.

Psychological Factors:

Some researchers think that vomiting can be a woman’s psychological reaction against the pregnancy. In such cases, counselling is the best remedy.
