Staying up late with diarrhea is mainly caused by endocrine disruption caused by staying up late. Once you stay up late, it is easy to cause endocrine disruption, which can lead to intestinal dysfunction, resulting in abdominal pain, diarrhea and other symptoms. In addition to this, the night is cold, if not pay attention to the warmth of the cold situation, may also cause intestinal cramps caused by diarrhea. If you eat some stimulating food while staying up late, it may also cause diarrhea. So usually try not to stay up late because once the endocrine disorder occurs, in addition to diarrhea, it will also cause different degrees of impact on the body organs. If you have diarrhea after staying up late, pay attention to timely treatment with oral medication such as montelukast and timely hydration.
