Why does an elderly person keep having diarrhea every few days?

Diarrhea usually refers to frequent loose or watery stools. When elderly individuals experience recurrent diarrhea, it is commonly caused by factors such as improper diet, indigestion, gastritis, gastric ulcer, or irritable bowel syndrome (IBS).

1. Improper Diet

The digestive system in older adults is generally more sensitive than in younger people. Consuming spicy, stimulating, or cold foods can irritate the gastrointestinal tract, leading to discomfort such as diarrhea and abdominal pain. It is recommended to eat small, frequent meals, maintain a light diet, and develop regular eating habits, which can gradually improve symptoms.

2. Indigestion

Indigestion may disrupt the balance of intestinal flora, reducing beneficial bacteria while increasing harmful ones, thereby irritating the gastrointestinal tract and causing discomfort including diarrhea, bloating, and abdominal pain. As advised by a physician, prokinetic medications such as domperidone tablets, mosapride citrate tablets, or cisapride capsules may help alleviate symptoms.

3. Gastritis

Inflammation may cause excessive secretion of mucosal fluids and stimulate the intestines, including increased gastric acid and other digestive juices, resulting in symptoms like stomach pain, bloating, loss of appetite, and diarrhea. It is recommended to take gastric mucosa-protecting medications under medical guidance. Commonly used drugs include aluminum magnesium carbonate chewable tablets, sucralfate tablets, and bismuth potassium citrate capsules to help relieve symptoms.

4. Gastric Ulcer

A gastric ulcer often damages the stomach's mucosal lining and affects gastric acid secretion, leading to excess acid production. This excess acid enters the intestines and irritates the intestinal mucosa, causing diarrhea, nausea, and vomiting. Follow your doctor’s instructions for treatment with acid-suppressing medications such as omeprazole sodium enteric-coated tablets, rabeprazole sodium enteric-coated tablets, or ranitidine hydrochloride capsules. In severe cases, surgical options such as partial gastrectomy or vagotomy may be performed by a qualified physician to help relieve symptoms.

5. Irritable Bowel Syndrome (IBS)

Abnormal central sensation, gastrointestinal motility disorders, or mental stress may lead to abnormal intestinal digestive function, resulting in IBS and persistent diarrhea. As directed by a physician, antidiarrheal medications such as loperamide hydrochloride capsules, compound diphenoxylate tablets, or smectite powder can help improve symptoms.

In some cases, antibiotics such as amoxicillin capsules, norfloxacin capsules, or cefixime capsules may be prescribed by a doctor to help manage the condition.

It is important to keep the abdomen warm and avoid exposure to cold. Seek timely medical evaluation at a hospital for proper diagnosis through relevant examinations, and follow an appropriate treatment plan based on test results.
