Acute diarrhea: press intestinal infections caused by bacterial or viral infections, toxins or after taking antibiotics that alter the normal balance of intestinal flora;
Chronic diarrhea: It persists over time and is caused by prolonged inflammation and food allergies.
Recurring diarrhea: this appears to alternate periods, sometimes in relation to the intake of foods to which you are sensitive (e.g. lactose).
You can further classify the condition according to various causes in the wild:
Diarrhea due to impaired absorption: caused by a malfunction of the mechanisms involved in enteric absorption of nutrients in food, the lack of absorption may be due to alterations in mucosal intestinale for inflammation or malignancy, reduction or disappearance of the intestinal villi (celiac disease), the non-food digestion by the enzymes (pancreatic disease), surgery (such as the intestinal bypass) that reduces the contact surface and absorption.
Osmotic diarrhea: osmotic laxatives caused by drugs such as salts of magnesium, which may alter the 'attract water and electrolyte balance in the gut.
Secretory diarrhea: which causes a high secretion in the intestine of water and electrolytes, in the case of tumors (colonic adenoma), of endocrine diseases, or of bacterial infections that produce toxins (cholera) or that damage the 'intestinal epithelium also causing inflammation, ulceration and bleeding that can be found in the feces (Shigella).
Diarrhea motor: increasing the speed of transit of the material and reducing the time available to the 'intestine to absorb nutrients for neurological reasons.
