Chronic Diarrhea: Symptoms, Causes, and Treatment Options

Chronic diarrhea does not present any inappropriate symptoms?

Hello Doctor, I have some health concerns I would like to ask you about.
I have been experiencing chronic diarrhea for the past three months without any other concerning symptoms.
Each time I use the restroom, it takes me 40 to 60 minutes to have a bowel movement that feels complete.
I haven't felt a sense of relief in a long time, and my stools seem to be poorly digested; sometimes they even float.
The color appears normal.
I have had hepatitis B since childhood and am currently a healthy carrier.
I am very particular about my lifestyle and have no stress or anxiety.
I also do not have lactose intolerance.
I often share meals with individuals who have tuberculosis, and I am concerned that I may have contracted the tuberculosis bacteria, which could have affected my colon and urinary system, as I have seen similar reports.
Currently, I am also experiencing frequent urination, urgency, and weak urine flow for the past four months.
Additionally, I have been engaging in masturbation for the past seven years.
I would like to know if taking medication for treatment would affect my studying ability or memory.
Thank you very much.

Dr. Yang Guojun reply Gastroenterology and Hepatology

Your symptoms require a colonoscopy (although the results may be normal) to rule out the possibility of colitis or colorectal cancer.
Additionally, for hepatitis B, it is important to have regular follow-up blood tests and ultrasound examinations every six months.
For the treatment of gastrointestinal symptoms, please consult a gastroenterologist.

More Info

Chronic diarrhea can be a frustrating and distressing condition, and understanding its symptoms, causes, and treatment options is crucial for effective management. Based on your description, it seems you have been experiencing chronic diarrhea for the past three months, characterized by prolonged bathroom visits (40-60 minutes) without a sense of complete relief. Your stools appear to be poorly digested, sometimes floating, but maintain a normal color. Additionally, you have a history of hepatitis B and are concerned about potential exposure to tuberculosis (TB) due to shared meals with an infected individual. You also mentioned experiencing urinary symptoms and are worried about the impact of any medications on your cognitive functions.

Symptoms of Chronic Diarrhea
Chronic diarrhea is generally defined as diarrhea that lasts for more than four weeks. Symptoms can include:
- Frequent loose or watery stools
- Urgency to have a bowel movement
- Abdominal cramps or pain
- A feeling of incomplete evacuation
- Weight loss (if diarrhea is severe)
- Dehydration (if fluid loss is significant)
In your case, the prolonged time spent in the bathroom and the sensation of incomplete evacuation are noteworthy. The floating stools may indicate malabsorption, which can occur due to various gastrointestinal disorders.

Possible Causes
Chronic diarrhea can arise from several underlying conditions, including:
1. Infections: Bacterial, viral, or parasitic infections can lead to diarrhea. Given your concern about TB, it’s essential to rule out any gastrointestinal infections.

2. Inflammatory Bowel Disease (IBD): Conditions like Crohn's disease or ulcerative colitis can cause chronic diarrhea and abdominal discomfort.

3. Irritable Bowel Syndrome (IBS): This functional gastrointestinal disorder can lead to chronic diarrhea, often triggered by stress or dietary factors.

4. Malabsorption Syndromes: Conditions such as celiac disease or pancreatic insufficiency can lead to poorly digested food in the stool.

5. Medication Side Effects: Some medications can cause diarrhea as a side effect, so it’s important to review any current medications with your healthcare provider.

6. Dietary Factors: Although you mentioned no lactose intolerance, other dietary components (like gluten or high-fat foods) could contribute to your symptoms.

Diagnostic Approach
Given your symptoms and history, it would be prudent to undergo a thorough evaluation, which may include:
- Stool Tests: To check for infections, malabsorption, or other abnormalities.

- Blood Tests: To assess for inflammation, liver function (considering your hepatitis B), and nutritional deficiencies.

- Imaging Studies: Such as an abdominal ultrasound or CT scan, to visualize any structural abnormalities.

- Endoscopy: If indicated, to directly visualize the gastrointestinal tract and obtain biopsies.

Treatment Options
The treatment for chronic diarrhea depends on the underlying cause:
- Dietary Modifications: Keeping a food diary may help identify any triggers. A low-FODMAP diet or elimination diet might be beneficial.

- Medications: Depending on the diagnosis, medications such as antidiarrheals (like loperamide), antibiotics (for bacterial infections), or anti-inflammatory drugs (for IBD) may be prescribed.

- Probiotics: These can help restore gut flora and may be beneficial in some cases of diarrhea.

- Hydration: Ensuring adequate fluid intake is crucial, especially if diarrhea is frequent.

Concerns About Cognitive Effects
Regarding your concern about medications affecting your memory or cognitive function, it is essential to discuss this with your healthcare provider. Some medications can have side effects that impact cognitive abilities, but this varies widely depending on the drug class and individual response. Your doctor can help you weigh the benefits and risks of any prescribed treatment.

Conclusion
Chronic diarrhea can significantly affect your quality of life, and it’s essential to work closely with your healthcare provider to identify the underlying cause and appropriate treatment. Given your complex medical history, including hepatitis B and potential exposure to TB, a comprehensive evaluation is warranted. Please ensure you communicate all your symptoms and concerns during your medical appointments for the best possible care.
