Diarrhea is a common ailment marked by frequent loose or watery bowel motions. It happens when the digestive system isn’t working properly, resulting in increased frequency and fluidity of bowel motions. 

The intestine’s usual process of absorbing water and electrolytes from the food you eat and the drinks you drink is disturbed during diarrhea. Instead of absorbing these fluids, the intestines accelerate their passage through the digestive tract, resulting in loose, watery stools. Depending on the underlying cause of the diarrhea, this procedure might take a few distinct forms. In some circumstances, the lining of the intestine may become irritated, inhibiting appropriate water absorption. In other circumstances, the muscles that carry food through the gut may become hyperactive, causing food to pass too quickly through the digestive tract and causing diarrhea.

Causes of Diarrhoea

  • Intestinal flu
  • Specific food allergies
  • Intestinal diseases (such as Crohn’s disease or ulcerative colitis)
  • Consuming meals that cause stomach discomfort
  • Infection with bacteria (the most common cause of food poisoning) or other species
  • Abuse of laxatives
  • Running (Some people acquire “runner’s diarrhea” for unknown reasons.)
  • Some types of cancer
  • Trouble absorbing specific nutrients, often known as “malabsorption”
  • Diarrhea may occur after constipation, particularly in patients with irritable bowel syndrome (IBS).

Diarrhea causes major symptoms such as blood or mucus in the stools, weight loss, and dehydration.

The following are the warning indications that patients should go to the hospital right away:

  • Diarrhea with blood or dark, tarry stools
  • High-grade fever accompanied by diarrhea
  • Diarrhea that lasts more than two days
  • Nausea accompanied by diarrhea
  • Severe abdominal discomfort in the right lower quadrant

Since Diarrhea can be a symptom of a variety of medical diseases, including irritable bowel syndrome (IBS), inflammatory bowel disease (IBD) such as Crohn’s disease and ulcerative colitis, microscopic colitis, or bacterial overgrowth, doctor would run diagnostic tests to understand the root cause and treatb the root cause their through medical management or surgical management.
