Gastroenteritis, commonly known as the stomach flu, is a condition that causes diarrhea and vomiting. The treatment for gastroenteritis depends on the severity of the symptoms. Here are some general tips for treating gastroenteritis:

• Replace lost fluids and electrolytes: Drink plenty of liquids such as water, fruit juices, sports drinks, and broths to replace lost fluids and electrolytes. Oral rehydration solutions, such as Pedialyte, Naturalyte, Infalyte, and CeraLyte, are also recommended to replace lost fluids and electrolytes. Avoid giving plain water to children with gastroenteritis as it is not absorbed well and wont adequately replace lost electrolytes. Avoid giving apple juice to children for rehydration as it can make diarrhea worse.

• Avoid certain foods: Avoid sugary foods, such as ice cream, sodas, and candy, as they can make diarrhea worse. Eat bland, easy-to-digest foods such as soda crackers, toast, gelatin, bananas, applesauce, rice, and chicken.

• Try over-the-counter medications: Adults can take over-the-counter medications such as loperamide (Imodium A-D) or bismuth subsalicylate (Pepto-Bismol, Kaopectate) to manage their symptoms. However, avoid these if you have bloody diarrhea or fever, which could be signs of another condition. Do not give store-bought anti-diarrheal medications to children unless advised by a doctor.

• Rest: Getting plenty of rest allows the body to recover.

It is important to note that you should not visit your GP if you think you have gastroenteritis, as it should get better on its own. Visiting your GP practice can put others at risk, so it’s best to phone 111 or your GP if you’re concerned or feel you need advice. Antibiotics may be prescribed if a bacterial infection is causing the symptoms.
