What Is Gastroenteritis (Stomach Flu)?

Gastroenteritis is a viral or bacterial infection 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 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.
