\"\"<\/a>Chronic diarrhea is defined as a decrease in stool consistency (loose BM) for more than 4 weeks (Am Fam Physician, 2011<\/a>).<\/p>

It can be divided into 3 categories<\/b>: <\/p>

- watery
- fatty (malabsorption)
- inflammatory<\/p>

Watery diarrhea<\/b><\/p>

Watery diarrhea may be subdivided into:<\/p>

- osmotic
- secretory
- functional, e.g. IBS<\/p>

Watery diarrhea includes irritable bowel syndrome (IBS), which is the most common cause of functional diarrhea. Another example of watery diarrhea is microscopic colitis, which is a secretory diarrhea affecting older persons.<\/p>

Laxative-induced diarrhea is often osmotic. <\/p>

Malabsorptive diarrhea<\/b><\/p>

Malabsorptive diarrhea is characterized by excess gas, steatorrhea, or weight loss. Giardiasis is a classic infectious example of malabsorptive diarrhea.<\/p>

Celiac disease (gluten-sensitive enteropathy) is also malabsorptive, and typically results in weight loss and iron deficiency anemia. <\/p>

Inflammatory diarrhea<\/b><\/p>

Inflammatory diarrhea, such as ulcerative colitis (UC) or Crohn disease, is characterized by blood and pus in the stool and an elevated fecal calprotectin level. <\/p>

Invasive bacteria and parasites also produce inflammation. Infections caused by Clostridium difficile (C. diff.) subsequent to antibiotic use have become increasingly common and virulent.<\/p>

Not all chronic diarrhea is strictly watery, malabsorptive, or inflammatory, because some categories overlap.<\/p>
