Diarrhea during breastfeeding is considered to be caused by diseases such as gastroenteritis and gastrointestinal cramps. During the lactation period, some mothers may over-eat soups with high fat content, such as carp soup and pig’s feet soup, in order to increase the amount of milk production. The body resistance of pregnant women during lactation is weak, and eating cold and raw foods may lead to the appearance of gastroenteritis and trigger diarrhea, which can be treated with probiotics or anti-inflammatory drugs according to the doctor’s guidance. The increased secretion of lactogen levels and the large changes in hormone levels in breastfeeding women may cause diarrhea due to gastrointestinal cramps after eating, which can be relieved by appropriate abdominal massage or hot towels or hot water bags on the navel area. If there is dehydration, you need to pay attention to appropriate rehydration.
