Causes of diarrhea
Coronaviruses cause about 40% of diarrhea that causes hospitalization in children younger than 5 years old.
Diarrhea has many causes. It can also be caused by an excessive intake of vitamin C or magnesium. Infectious diseases are the most important causes for human health. The medical definition of diarrhea includes the production of more than 200 grams of stool per day, as some features of diarrhea can occur in other conditions.
Diarrhea occurs because the large intestine does not absorb enough fluid. Meals are digested in liquid form before reaching the large intestine. The large intestine absorbs water, making the remaining material semi-solid. If the large intestine is damaged or inflamed, water absorption is inhibited and watery stools occur.
The most common cause of diarrhea is viral infection or bacterial toxins. If a healthy person has diarrhea due to a viral infection, they will recover in a few days, but in a week at most. However, in sick or malnourished people, diarrhea can lead to severe dehydration and can be life-threatening if left untreated.
Among the causes of diarrhea are many serious diseases; may indicate a chronic condition such as dysentery, cholera, botulism, or Crohn’s disease. Although diarrhea is not usually present in patients with appendicitis, it is a common manifestation of appendicitis. Dietary diarrhea may be the cause of lactose intolerance.
