What to Eat and Drink During Gastroenteritis

What is Gastroenteritis?

Gastroenteritis is an inflammation of the lining of the intestines caused by bacteria, viruses or parasites. These germs are usually carried in the contaminated food, water or beverages, which may affect an individual or a group of people when consumed. Generally, gastroenteritis resolves with good home care till one feels better.


What We Don’t Know

Most frequently, dehydration occurs with gastroenteritis. Babies, young children, elderly and people with weak immune systems are more prone to dehydration. This most likely occurs when one fails to replace fluid loss due to diarrhea and vomiting. If left untreated, dehydration may lead to serious health problems such as organ damage, shock, coma, or even death. 


Bacterial gastroenteritis is caused by eating food or drinking beverages infected with bacteria (such as Salmonella or Escherichia coli), which may also be called food poisoning. Viral gastroenteritis is caused most often by a Norovirus infection. These germs may get into your body in many ways:

  • Use of infected utensils
  • Close contact with an infected person
  • Consumption of contaminated food or water in any of the following ways:
      1. Improperly washed raw fruits or vegetables
      2. Frozen or refrigerated food items that are not stored at the proper temperature,
      3. especially fruit juices and dairy products
      4. Under-cooked meat or eggs
      5. Water from a well or stream, or untreated water


Symptoms of bacterial gastroenteritis often depend on the type of bacteria that caused the sickness. In case of viral gastroenteritis, symptoms are usually seen within 4 hours to 2 days of contact with the virus. Common symptoms include:

  • Diarrhea
  • Abdominal cramps
  • Abdominal pain
  • Nausea
  • Vomiting
  • Bloody stools
  • Loss of appetite
  • Fever
  • Headache

One may experience symptoms such as:

  • Chills, clammy skin, or sweating
  • Muscle pain or joint stiffness
  • Weight loss 


Most people recover with no treatment within a few days. The goal of the treatment is to ensure that electrolytes and fluids (salt and minerals) lost through vomiting or diarrhea must be replaced by intake of extra liquids. One should drink enough fluids between meals, despite being able to eat otherwise.

Keep Stomach Woes at Bay

Here are some foods and beverages that may help resolve your stomach problems and prevent further complications. Adhering to the following advice may also help you bounce back faster from illness:
