What Is Gastroenteritis (Stomach Flu)?

Gastroenteritis is a viral or bacterial infection that is characterized by symptoms like diarrhea and vomiting. It causes inflammation of the stomach lining and intestines and is commonly referred to as stomach flu.

One of the most common ways in which you can contract gastroenteritis is through direct contact with an infected person or ingesting contaminated food/water.

Healthy individuals often recover from this condition without any complications. However, for those with a weak immune system, like infants and older adults, gastroenteritis can prove to be life-threatening.

Let us now look at the common causes of gastroenteritis.

What Causes Gastroenteritis?

The most common cause of gastroenteritis is a virus. It can be triggered by various kinds of viruses like rotavirus and norovirus.

Although not as common, gastroenteritis may also be triggered by bacteria like E. coli, shigella, and salmonella.

Gastroenteritis can also be caused by certain parasites like giardia and cryptosporidium, which are commonly found in contaminated swimming pools.

Some factors that can further increase your risk of developing gastroenteritis are discussed below.

• Age – Infants and older adults are at a higher risk of contracting gastroenteritis.
• Weakened immunity due to an ongoing medical condition.
• Drinking water that is contaminated with heavy metals like arsenic, lead, or mercury.
• Increased consumption of acidic foods.
• Eating seafood contaminated with toxins.
• Certain medications like antibiotics, antacids, chemotherapy drugs, and laxatives.

If you have gastroenteritis, you are quite likely to exhibit the following signs and symptoms.

Signs And Symptoms Of Gastroenteritis

The signs and symptoms of gastroenteritis may include:

• Watery diarrhea
• Vomiting
• Stomach pain
• Fever
• Nausea
• Cramping
• Headache
• Dehydration
• Dry skin and mouth
• Lightheadedness
• Increased thirst

In infants, you may look for signs of fewer and drier diapers. Thirst and a dry mouth and skin can also be common indications of stomach flu in infants. If you doubt that you or your little one has gastroenteritis, waste no time in seeing a doctor immediately.

How To Test For Gastroenteritis

The doctor is quite likely to diagnose gastroenteritis based on the symptoms exhibited by the patient on physical examination.

If a viral cause is suspected, the doctor may suggest a stool test to detect rotavirus or norovirus. A stool test can also help rule out a possible parasitic or bacterial infection.

Once the cause of gastroenteritis is determined, the doctor may prescribe treatment accordingly.

Medical Treatments

The doctor may prescribe antibiotics if the person has contracted bacterial gastroenteritis. Some over-the-counter medications can be taken to manage the symptoms. However, if the cause is viral, there is no specific medical treatment to help with the condition. The doctor may suggest some self-care measures to overcome stomach flu faster in such cases.

Frequently Asked Questions

How long does gastroenteritis last?

The symptoms of gastroenteritis usually appear 1-3 days post-exposure to the infection. Its symptoms usually last for 1-2 days but may go on to last for even 10 days in some individuals.

Are the stomach flu and food poisoning the same thing?

Stomach flu is commonly caused by a viral infection, while food poisoning may be caused by a range of bacteria, viruses, and parasites. While stomach flu can be transmitted via contaminated food/water or by direct contact with an infected person, food poisoning usually occurs due to the cross-contamination of food items with troublesome microbes.

What is the difference between gastritis and gastroenteritis?

Gastritis is a condition that causes inflammation of the stomach lining. Underlying medical conditions like Crohn’s disease and sarcoidosis can trigger this condition. Gastritis can also be a result of a bacterial infection or an injury to your stomach lining due to your dietary choices.

On the other hand, gastroenteritis is a stomach infection that is commonly caused by viruses. However, in some cases, gastroenteritis may also be caused by a bacterial or parasitic infection.

Both these conditions lead to the inflammation of the stomach lining and cause symptoms like nausea and vomiting. However, gastroenteritis is more severe and can prove to be life-threatening to people with a weak immune system.

What to eat when you have the stomach flu?

If you have the stomach flu, it is very important to keep yourself well-hydrated by drinking plenty of fluids like soups, rice water, and ORS. You may suck on some ice chips if you have trouble keeping the fluids down.

You can also give the BRAT diet a try, which stands for Bananas, Rice, Applesauce, and Toast. This diet can help in firming your stool and treating diarrhea (12).
