The symptoms of exhaustion in early pregnancy are mainly considered to be caused by gastrointestinal flocculation. This is because the digestive tract tissues of women are affected by increased levels of hormones such as adrenaline, progesterone and estrogen in the body after conception, which can lead to increased peristaltic activity. After the fermentation reaction between nutrients and gas-producing bacteria in the gastrointestinal cavity, gas-like substances will be produced, and the internal gas will enter the lower gastrointestinal tract rapidly under the effect of vigorous peristalsis, and stimulate the anal sphincter, resulting in frequent farting and increased exhaustion in pregnant women. However, we do not exclude the possibility of other types of diseases such as H. pylori infection, irritable bowel syndrome, chronic gastroenteritis, etc., because the normal function of digestive tract tissues will be obstructed after the occurrence of these types of diseases, which will cause such adverse symptoms and reactions.
