How does irritable bowel syndrome occur?

The causes of irritable bowel syndrome usually include abnormal gastrointestinal motility, intestinal microecological imbalance, mental and psychological disorders, etc., and are analyzed as follows:

1. Abnormal gastrointestinal motility

If the patient's gastrointestinal motility is abnormal, the intestinal peristalsis speed increases or weakens, and the intestinal tract responds too strongly to the dynamics of eating, intestinal dilatation and certain gastrointestinal hormones, which can easily cause irritable bowel syndrome.

2. Imbalance of intestinal microecology

If the number of probiotics such as lactic acid bacteria and bifidobacteria in the patient's intestine is unbalanced, it can easily lead to intestinal dysfunction and irritable bowel syndrome.

3. Mental and psychological disorders

If the patient is under long-term negative emotions such as anxiety and depression, or is stimulated by acute or chronic stress events, it can easily cause irritable bowel syndrome.
