The main symptoms of Irritable Bowel Syndrome (IBS) include abdominal pain, changes in stool characteristics such as diarrhea or constipation, and some patients may also experience symptoms like stools with white mucus. When patients with Irritable Bowel Syndrome undergo a colonoscopy, the intestinal mucosa shows no organic changes; the symptoms are merely discomfort, which are primarily influenced by psychological factors. Consuming probiotics to regulate the gut flora can help alleviate these symptoms. Furthermore, patients with Irritable Bowel Syndrome should avoid tension, anxiety, or depression, and maintain a cheerful mood, which is beneficial for recovery. Dietary considerations should focus on light and easily digestible foods.
