The symptoms of chronic diarrhea are mainly caused by factors such as intestinal dysfunction, infection, food intolerance, and inflammatory bowel disease. Treatment requires measures such as anti-infective therapy, regulation of intestinal flora, and dietary adjustments, depending on the cause. Chronic diarrhea is usually defined as increased bowel movements or loose stools lasting more than four weeks. Its causes are complex, and targeted treatment is necessary after a clear diagnosis.
1. Intestinal dysfunction: Irritable bowel syndrome (IBS) is a common cause, manifesting as abdominal pain, bloating, diarrhea, or alternating constipation. Symptoms can be improved through dietary adjustments such as increasing dietary fiber and avoiding spicy foods, as well as medications such as loperamide and probiotics.
2. Infection: Bacterial, viral, or parasitic infections can cause chronic diarrhea. Common pathogens include Salmonella, rotavirus, and Giardia. Treatment requires selection of antibiotics, antiviral drugs, or anthelmintics based on the pathogen, while also replenishing electrolytes and fluids.
3. Food intolerance: Lactose intolerance, gluten sensitivity, etc., can cause diarrhea. It is necessary to identify intolerant foods through dietary elimination and avoid consuming them. If necessary, lactase should be used or gluten-free foods should be chosen.
4. Inflammatory bowel disease: Crohn's disease and ulcerative colitis are the main types, manifesting as abdominal pain, diarrhea, and bloody stools. Treatment includes the use of aminosalicylic acid drugs, immunosuppressants, and biologics; surgery may be required in severe cases.
5. Other causes: Drug side effects, endocrine disorders, tumors, etc., can also lead to chronic diarrhea. Treatment may require adjusting medication, treating the underlying disease, or undergoing surgery such as tumor removal, depending on the specific cause.
Chronic diarrhea has diverse causes, and treatment must be tailored to the specific cause. Patients should seek medical attention promptly for a thorough examination and individualized treatment plan developed under the guidance of a doctor to improve symptoms and prevent complications. Maintaining healthy lifestyle and dietary habits also helps control the condition and promote recovery.
