Gastroenteritis Treatment for Children

What is Gastroenteritis?

Gastroenteritis, often called the “stomach flu,” is an infection or irritation of the stomach and intestines, leading to diarrhoea and vomiting. It is usually caused by a virus, such as rotavirus or norovirus, but bacteria and parasites can also be responsible. When gastroenteritis is transmitted through contaminated food, it is referred to as food poisoning. The condition is highly contagious, particularly in young children, and spreads through direct contact, contaminated food or water, or shared surfaces.

How is gastroenteritis managed?

• Preventing dehydration: Encourage small, frequent sips of fluids such as oral rehydration solutions, diluted juices, or clear broths. Avoid sugary or caffeinated drinks, as they can worsen symptoms.

• Dietary adjustments: Older children may be able to tolerate the BRAT diet i.e bland foods like bananas, rice, applesauce and toast. Avoid dairy and greasy foods until symptoms resolve.

• Rest and recovery: Allow your child plenty of rest. Avoid forcing them to eat if they are not hungry, as hydration is the priority.
• Medications: Anti-nausea medication may help in cases where vomiting is preventing fluid intake. Anti-diarrhoeal medication like Imodium is generally not recommended for children.
