Chronic diarrhea and abdominal pain can be distressing symptoms that significantly impact your quality of life. Given that you have been experiencing these symptoms for six years, it is crucial to approach this situation methodically to identify the underlying cause and find appropriate treatment.
First, it is essential to understand that chronic diarrhea can stem from various conditions, including but not limited to irritable bowel syndrome (IBS), inflammatory bowel disease (IBD) such as Crohn's disease or ulcerative colitis, infections, food intolerances, and malabsorption syndromes. The abdominal pain you describe, particularly if it is crampy and occurs in episodes, may be related to the underlying gastrointestinal issue.

To begin the diagnostic process, you should consider the following tests and evaluations:
1. Comprehensive Blood Tests: These can help assess your overall health and check for signs of infection, inflammation, or anemia. Specific tests may include a complete blood count (CBC), inflammatory markers (like C-reactive protein), and liver and kidney function tests.

2. Stool Tests: Since your symptoms include diarrhea, stool tests are vital. These can check for infections (bacterial, viral, or parasitic), the presence of blood, and markers of inflammation. A stool culture can help identify specific pathogens, while tests for fat in the stool can indicate malabsorption.

3. Endoscopy Procedures: Depending on your symptoms and initial test results, your doctor may recommend an upper endoscopy (esophagogastroduodenoscopy or EGD) or a colonoscopy. These procedures allow direct visualization of the gastrointestinal tract and can help diagnose conditions like IBD, celiac disease, or other structural abnormalities.

4. Imaging Studies: An abdominal ultrasound or CT scan can provide additional information about the organs in your abdomen and help identify any structural issues, such as blockages or abnormalities in the intestines.

5. Food Allergy or Intolerance Testing: If there is a suspicion that your symptoms may be related to food, your doctor may recommend tests for food allergies or intolerances, such as lactose intolerance or celiac disease.

6. Hydrogen Breath Tests: These tests can help diagnose conditions like lactose intolerance or small intestinal bacterial overgrowth (SIBO), which can contribute to diarrhea and abdominal pain.

7. Psychological Evaluation: Since chronic gastrointestinal symptoms can be exacerbated by stress and anxiety, it may be beneficial to consider a psychological evaluation. Conditions like IBS are often linked to psychological factors, and addressing these can be an essential part of treatment.

Given the chronic nature of your symptoms, it is advisable to consult a gastroenterologist, a specialist in digestive disorders. They can guide you through the appropriate tests and help interpret the results to formulate a treatment plan tailored to your needs.

In the meantime, keeping a symptom diary can be beneficial. Documenting when your symptoms occur, what you eat, and any other factors (like stress levels) can provide valuable insights for your healthcare provider.

Lastly, while you seek answers, consider dietary modifications that may alleviate your symptoms. Some individuals find relief by following a low-FODMAP diet, which reduces certain carbohydrates that can trigger gastrointestinal symptoms. However, any dietary changes should be discussed with a healthcare professional to ensure they are appropriate for your situation.

In conclusion, chronic diarrhea and abdominal pain warrant a thorough evaluation to determine the underlying cause. By working closely with your healthcare provider and undergoing the recommended tests, you can take significant steps toward understanding your condition and finding effective treatment options.
