Medic for Gastroenteritis

Gastroenteritis, also known as stomach flu or gastric flu, is a condition in which the stomach and the small intestine become inflamed mainly due to a viral or bacterial infection. At times, parasites and food borne illness (through shell fish grown in contaminated water, improperly cooked or raw shell fish, or poisonous mushrooms) can cause gastroenteritis.

In the US nearly 100 million people are affected by stomach flu, of which around 2% may require hospitalization. Whereas in developing countries, this is one of the leading causes of death due to dehydration.

The primary causes of gastroenteritis are the rotavirus, norovirus, parvo virus, and adenovirus and bacteria known as Escherichia coli ( E. coli) and Campylobacter, Staphylococcus aureus, Clostridium difficile, etc. There are many other infectious agents that can cause it.


Gastroenteritis can be a highly contagious disease. Symptoms typically appear within 12 to 48 hours after exposure to the infectious agent and last for 2 to 10 days, depending on the type of infection.

Common symptoms of gastroenteritis include upset stomach, nausea, mild to moderate diarrhea, stomach cramps and vomiting. It can also be accompanied by fever, headache, chills, body aches, dry skin, and dry mouth.

Severe gastroenteritis can be accompanied by blood in vomit and stools, persistent vomiting for more than 48 hours, high grade fever for more than 101 degrees Fahrenheit (40 degrees Celsius), swollen abdomen, increasing intensity of abdominal pain, severe dehydration characterized by weakness, faint feeling, reduced output of urine, dry skin, etc. In such cases, kindly consult a doctor on emergency basis.

Anyone can suffer from gastroenteritis, but children are more prone to it due to their weak immune systems. The elderly and children are more prone to the effects of gastroenteritis and require more care.


When suffering from gastroenteritis, it is essential to replenish the body with fluids and electrolytes as the diarrhea and vomiting can create an imbalance of electrolytes (salt and minerals) in the body, which causes dehydration.

Dehydration affects the body’s normal functioning and can even delay the healing process. So, drink plenty of water and clear nutritious fluids like broths, soups, and rice water. Eat easy to digest foods such as toast, bananas, etc. Also, get as much rest as possible.

Along with rehydration and rest, you can try some simple and easy home remedies to help treat the problem and reduce the symptoms. It is usually a self-limiting condition that does not require medication.
