Diarrhea and stomach rumbling in mid-pregnancy may be caused by indigestion in the gastrointestinal tract or gastroenteritis caused by catching a cold. Usually, if you eat cold or unclean food or improper diet, it may lead to diarrhea. During pregnancy, pregnant women should pay attention to the warmth of the abdomen, and drink more warm water to replenish the body’s water to avoid dehydration, eat more light and easily digestible food, and eat less and more meals, eat warm fruits and vegetables, and do not eat too greasy, spicy and stimulating food. If the diarrhea is serious, so serious that you can not eat, you must go to the hospital for examination and symptomatic treatment, in order to quickly correct the electrolyte disorder and ketosis.
