What are the causes of diarrhea?

Diarrhea can be divided into acute diarrhea and chronic diarrhea. Acute diarrhea is acute, the course of disease is 2-3 weeks, and it is mostly caused by infection, including bacterial and viral infections.

There are many reasons for chronic diarrhea, including infectious diarrhea, intestinal nonspecific inflammation, tumor, intestinal malabsorption and so on. Some systemic diseases such as chronic renal insufficiency, diabetes and systemic lupus erythematosus. Can also cause diarrhea. In addition, some patients have gastrointestinal motility disorder caused by visceral hypersensitivity.

After the gastrointestinal tract is stimulated by cold, such as cold weather, cold abdomen or eating cold food, the peristalsis of the gastrointestinal tract will be accelerated or irregular contraction will occur. At this time, the time for fecal formation will be shortened and diarrhea will be easy.

Causes of diarrhea in summer:

1, It's hot in summer, eating too many cold fruits, cold drinks or food, and staying in an air-conditioned room for a long time will lead to diarrhea.

2. Summer food has a short shelf life and is easy to deteriorate. Eating leftovers or other food contaminated by pathogenic bacteria can cause fever, nausea, vomiting, abdominal pain and diarrhea;

3. Eating too much or eating too many kinds of food will lead to indigestion, and the food will stay in the gastrointestinal tract for a short time, which will lead to abdominal distension, nausea and diarrhea.
