What causes fluid diarrhea?

The main causes of diarrhea are lactose intolerance, food allergy, food poisoning, etc.

1. Lactose

intolerance is mainly caused by lactase deficiency, which can cause patients to be unable to fully digest lactose. If the fluid food contains more lactose, the undigested lactose after eating will lead to an increase in osmotic pressure in the intestinal tract, which will increase the water flowing into the intestinal tract, so it will cause diarrhea.

2. Food allergy

If the patient is allergic to fluid food, there will be abnormal immune reaction after eating, manifested as diarrhea, abdominal pain, etc.

3. Food poisoning

If the fluid food is contaminated by bacteria, viruses or other harmful substances, it may lead to food poisoning, which will cause diarrhea, vomiting and other symptoms.
