Introduction Diarrhea in children is not uncommon, but it is one of the biggest worries for parents. Diarrhea can cause your child to lose a lot of fluids and electrolytes, leading to dehydration and malnutrition. This article will introduce some ways to quickly relieve diarrhea in children.

Because a large amount of water is excreted from the body during diarrhea, severe dehydration will occur if water is not replenished in time.

For children who need to drink electrolyte solutions, you can buy saline solution from your local drugstore or make your own salt-sugar solution. homemade salt
