Introduction
In general, having several bowel movements a day after drinking green tea may be caused by physiological factors, high-fiber diet, physical weakness, gastroenteritis, or ulcerative colitis. If symptoms are severe, it is advisable to seek medical attention promptly to avoid delaying treatment. It is also important to maintain healthy daily habits and avoid spicy or irritating foods, which may hinder recovery.

Under normal circumstances, having several bowel movements a day after drinking green tea may be caused by physiological factors, high-fiber diet intake, physical weakness, gastroenteritis, or ulcerative colitis. A detailed analysis is as follows:

1. Physiological reasons

Green tea contains theine (tea alkaloids), which has a cleansing effect on the intestines. Drinking green tea can promote intestinal motility and facilitate defecation, possibly leading to multiple bowel movements in a day. This is usually a normal physiological phenomenon and not a cause for concern. Symptoms typically resolve spontaneously after stopping green tea consumption and increasing intake of warm water.

2. High-fiber diet intake

Green tea contains certain dietary fibers. A high-fiber diet may increase intestinal motility and frequency of bowel movements. Consuming green tea along with a high-fiber diet might further increase the number of daily bowel movements. Maintaining a balanced diet is recommended to help alleviate symptoms.

3. Physical weakness

If an individual has a naturally weak constitution and suddenly consumes excessive amounts of green tea—especially if they have never drunk it before—it may irritate the gastrointestinal tract and lead to diarrhea. Reducing green tea intake in daily life can help relieve these symptoms.

4. Gastroenteritis

Patients with pre-existing gastroenteritis may already experience indigestion. Green tea is considered cooling in nature and may further irritate the stomach and intestines, enhancing intestinal motility and potentially causing diarrhea or increased bowel movements. Under a doctor's guidance, medications such as montmorillonite powder or bismuth potassium citrate tablets may be used for treatment.

5. Ulcerative colitis

In patients with ulcerative colitis, damage to the colon mucosa commonly causes recurrent diarrhea, abdominal pain, and similar symptoms. The cooling nature of green tea may irritate the damaged colon lining, resulting in several bowel movements per day. Under medical supervision, drugs such as mesalazine tablets or sulfasalazine tablets may be prescribed for treatment.

If symptoms are severe, prompt medical attention is recommended to avoid delaying diagnosis and treatment. It is also important to maintain healthy lifestyle habits and avoid spicy or irritating foods, which may hinder recovery.
