Possible Causes
Generally, Diarrhea can be related to:
- Zollinger-Ellison Syndrome
Zollinger-Ellison Syndrome is a rare condition where one or more tumors in the stomach, known as gastrinomas, result in the production of too much gastric acid. The excessive acid may cause peptic ulcers in your stomach or intestine, resulting in symptoms such as heartburn, abdominal pain, acid reflux, and vomiting. Some people with this condition may have a genetic problem known as multiple endocrine neoplasia type 1 (MEN1).
- Watery Diarrhea, Hypokalemia, and Achlorhydria (WDHA) Syndrome
WDHA syndrome, which stands for watery diarrhea, hypokalemia, and achlorhydria, is a rare condition caused by an excess of vasoactive intestinal polypeptide (VIP) secreted by certain tumors. VIP is both a neuromodulator and a neurotransmitter that dilates blood vessels, regulates smooth muscle activity, cell secretion, and blood flow in the gastrointestinal tract.
- Drug-Induced Colitis
Inflammation of the large intestines can be caused by various drugs, with non-steroidal anti-inflammatory drugs (NSAIDs) being the most common.
- Eosinophilic Gastroenteritis
- Pellagra
- Malabsorption Syndrome / Protein Losing Gastroenteropathy
Infectious enteritis
- Ulcerative Colitis
Related Serious Diseases
Sometimes, Diarrhea may be related to these serious diseases:
- Amebic Dysentery
Infection of the gut with microorganisms called amoeba. It can be caused by contaminated food and water.
- Pseudomembranous Colitis
