Overview
Differential diagnosis
It is important to differentiate chronic diarrhea based on the kind of diarrhea that is produced. Chronic diarrhea can be subdivided into three major types; fatty, inflammatory, or watery. Watery chronic diarrhea can then further be sub-divided into osmotic or secretory diarrhea. Below is a list of differential Diagnosis of Chronic Diarrhea by Stool Characteristics.[1]
- Watery diarrhea
Osmotic diarrhea
Carbohydrate malabsorption
Osmotic laxatives (eg, Mg++, PO4−3, SO4–2)
Secretory diarrhea
Bacterial toxins
Bile acid malabsorption
IBD (some cases)
Crohn's disease
Microscopic colitis
Collagenous colitis
Lymphocytic colitis
Medications and toxins
Disordered motility
Diabetic autonomic neuropathy
IBS
Postsympathectomy diarrhea
Postvagotomy diarrhea
Endocrinopathies
Addison's disease
Neuroendocrine tumors
Hyperthyroidism
Mastocytosis
Medullary carcinoma of the thyroid
Idiopathic secretory diarrhea (epidemic and sporadic)
Stimulant laxative abuse
Neoplasia
Colon carcinoma
