Question

What is diarrhoea? How is it caused? How can it be prevented? for class 7
​

Answer 1

Answer:

Diarrhoea is caused by various factors but it does not occur due to any underlying disease. The primary reason for this is the reduction in the absorption of fluid by intestines and also an increase in the secretion of fluid or liquid and speedy passage of bowel waste through intestines.

Answer 2

Explanation:

Diarrhoea is the passage of 3 or more loose or liquid stools per day, or more frequently than is normal for the individual.

Infection is spread through contaminated food or drinking-water, or from person-to-person as a result of poor hygiene.

Interventions to prevent diarrhoea, including safe drinking-water, use of improved sanitation and hand washing with soap can reduce disease risk.
