Study Notes
General Laboratory Tests in Chronic Diarrhea
- Recurrent pancreatitis or excessive alcohol consumption can indicate chronic pancreatitis.
- Abdominal pain is uncommon in hypothyroidism, but it may occur alongside constipation and ileus; thyroid-stimulating hormone levels should be tested if thyroid dysfunction is suspected.
- Irritable bowel syndrome (IBS) is characterized by pain correlated with bowel habit changes, but other functional disorders can present similarly or with isolated pain, such as functional abdominal pain syndrome and functional dyspepsia.
Diagnostic Workup Considerations
- Young patients with no organic disease evidence may receive symptomatic treatment after initial workup.
- Additional invasive testing should target specific diseases rather than serve as broad screening.
- Caution is advised when diagnosing new-onset functional illness in individuals over 50 years.
Key Symptoms and Conditions
- Symptoms like fatigue, malaise, nausea, vomiting, and hypotension combined with hyponatremia or hyperkalemia may suggest adrenal insufficiency.
- Hypercalcemia can cause abdominal pain, potentially leading to pancreatitis or constipation.
Chronic Abdominal Pain Diagnostics
- Functional disorders are the most common cause of chronic abdominal pain, predominantly IBS.
- Initial evaluation aims to differentiate between benign functional illnesses and organic pathologies, with signs suggesting organic disease including weight loss, fever, hypovolemia, electrolyte imbalances, gastrointestinal blood loss, anemia, or malnutrition.
- Normal laboratory results typically indicate functional abdominal pain.
Recommended Laboratory Studies
- Common laboratory tests include:
- Complete blood count with differential
- Electrolytes, blood urea nitrogen (BUN), creatinine, and glucose levels
- Calcium levels
- Liver enzymes (aminotransferases, alkaline phosphatase, bilirubin)
- Lipase and/or amylase
- Serum iron, total iron binding capacity, and ferritin
- Anti-tissue transglutaminase for gluten sensitivity
Further Evaluation and Imaging
- Investigate iron deficiency with a suspicion of celiac disease, inflammatory bowel disease (IBD), or malignancy such as colorectal cancer.
- For patients with low suspicion of IBD, fecal calprotectin testing can help determine the necessity for colonoscopy in the presence of intestinal inflammation.

Description
This quiz focuses on the approach to diagnosing chronic diarrhea, particularly in resource-abundant settings. It covers key aspects such as the role of laboratory tests and the significance of a history of pancreatitis or alcohol intake as potential indicators of chronic pancreatitis. Additionally, understand how other conditions, such as hypothyroidism, may contribute to abdominal pain.
