Why do you have diarrhea every time you drink milk and milk powder

1. Lactose intolerance

Most

milk and milk powder contain a lot of lactose, and some people will lack lactase in the small intestine after adulthood. It is difficult to decompose and absorb lactose, which can increase the osmotic pressure of the colon, resulting in a large amount of water exudation, thus causing the above discomfort symptoms.

2. Gastroenteritis

Gastroenteritis is an inflammatory lesion that occurs in the gastrointestinal mucosa. If you ingest cooler milk and milk powder during the illness, it may further stimulate the gastrointestinal tract and accelerate gastrointestinal motility, causing related abnormalities.

3. Food deterioration

Due to long storage time, it may deteriorate, and then produce a large number of harmful substances. After drinking, it may stimulate the gastrointestinal tract and cause diarrhea.
