Persistent Diarrhea

Diagnosis of persistent diarrhea begins with a thorough medical history and physical examination. Your doctor may order tests such as stool tests to look for bacteria, viruses, or parasites, blood tests to check for signs of infection or inflammation, and imaging or endoscopic tests to visualize the intestines.

Stool tests can identify the presence of bacteria, viruses, or parasites that may be causing diarrhea. They can also detect certain proteins or blood in the stool, which can be a sign of inflammation or damage to the intestines.

'Red flag' symptoms that could suggest a severe immune system disorder include bloody or black stools, severe abdominal pain, unexplained weight loss, fever, or signs of dehydration like dry mouth, dizziness, or decreased urine output. If you're experiencing these symptoms along with persistent diarrhea, seek medical attention.

If you're experiencing persistent diarrhea, you should initially consult with your primary care doctor. Depending on your symptoms and the suspected underlying cause, you may be referred to a specialist such as a gastroenterologist or an infectious disease specialist.

Certain lifestyle factors, such as diet and stress, can contribute to persistent diarrhea. Foods high in fiber, fat, or sugar can exacerbate diarrhea in some people, and stress or anxiety can affect digestion and bowel function.

Managing stress, maintaining a balanced diet, and staying hydrated can help manage persistent diarrhea. Depending on the cause, your doctor may recommend a specific diet, such as a gluten-free diet for celiac disease or a low-fiber diet for inflammatory bowel disease.

Treatment for persistent diarrhea due to immune system disorders depends on the specific cause. For infections, antibiotics or antiparasitic drugs may be needed. For autoimmune or inflammatory conditions, medications to reduce inflammation and modulate the immune response may be prescribed.

While the underlying immune system disorder may not always be curable, the associated persistent diarrhea can often be effectively managed with appropriate treatment. It's important to work closely with your healthcare team to manage your symptoms and maintain a good quality of life.

Persistent diarrhea can be a common symptom of many immune system disorders. It's a way for the body to attempt to fight off infections or diseases.
