The stomach grumbling after pregnancy is generally caused by hunger, may be due to the slowing of intestinal peristalsis, gastric acid secretion reduction caused by intestinal flatulence performance, may also be caused by contraction stimulation. 1, hunger state: pregnant women’s body metabolism is faster, the body’s demand for energy consumption is greater, more nutrients required for the growth and development of the fetus in late pregnancy. Therefore, soon after eating, the pregnant woman’s intestines and stomach in the case of empty grinding will make a gurgling sound, which is a normal physiological phenomenon, do not need to worry too much, and will generally ease after eating. 2, intestinal flatulence: is also one of the most common problems during pregnancy, mainly in early pregnancy progesterone content increases, intestinal peristalsis slows down, resulting in reduced secretion of gastric acid, which affects the digestive function and produces a gurgling sound. In addition, improper diet structure can also lead to intestinal flatulence, such as often eat beans, starch, noodles, carbonated drinks and other gas-producing food, or constipation, can also lead to stomach grumbling. 3, contraction stimulation: contractions will also stimulate the peristalsis of the gastrointestinal tract leading to diarrhea, which makes the stomach have grumbling. Therefore, it is recommended that pregnant women when the stomach grumbles, to seek medical attention in a timely manner to clarify the cause before treatment. You should do proper exercise daily to promote gastrointestinal peristalsis and also eat more easily digestible food to avoid causing indigestion.
