Exudative Diarrhea Mucosal inflammation can occur with diverticulitis, inflammatory bowel disease, or invasive enteric infections such as shigella, salmonella, or campylobacter. The etiology for the inflammatory response in ulcerative colitis and Crohn’s disease remains poorly understood.

What is exudative diarrhea?

Osmotic diarrhea occurs when too many solutes — the components of the food you eat — stay in your intestine and water can’t be absorbed properly. This excess water causes your bowel movements to be loose or more liquid than solid.

What is the pathophysiology of infectious diarrhea?

In bacterial and viral diarrhea, the watery stool is the result of injury to the gut epithelium. Epithelial cells line the intestinal tract and facilitate the absorption of water, electrolytes and other solutes. Infectious etiologies cause damage to the epithelial cells which leads to increased intestinal permeability.

What cause osmotic diarrhea?

Osmotic diarrhea is usually due to ingestion of poorly absorbed cations (eg, magnesium) or anions (eg, phosphate, or sulfate), which are often contained in laxatives and antacids, or to carbohydrate malabsorption from ingestion of poorly absorbed sugars or sugar alcohols (eg, sorbitol or xylitol).

What does nocturnal diarrhea mean?

Nocturnal diarrhea refers to diarrhea that happens at night. Chronic nocturnal diarrhea can be a sign of a more serious health condition, such as diabetes, a bowel disorder, or an infection. Persistent diarrhea can also interrupt sleep and affect the quality of life.

What is the science behind diarrhea?

Diarrhea is caused by increased secretion of fluid into the intestine, reduced absorption of fluid from the intestine or rapid passage of stool through the intestine. Symptoms associated with diarrhea include abdominal pain, especially cramping.

What happens in intestine during diarrhea?

Diarrhea is when you have an increased number of bowel movements or you have bowel movements that are watery or loose. It’s caused by attenuated water absorption or inappropriate water secretion by the intestines. It is your body’s way of quickly clearing viruses, bacteria, or toxins from the digestive tract.

How does diarrhea occur in the large intestine?

2 Muscles in the colon move the stool along to the rectum for passage out of the body. When something disrupts the digestive process, causing too much liquid to be eliminated or the solid waste to pass too quickly through the large intestine, diarrhea can result.
