10 Home Remedies For Gastroenteritis (Stomach Flu) + Prevention Tips

If you are experiencing stomach cramps, vomiting, and watery stools, you need to start following some home remedies for gastroenteritis immediately. Gastroenteritis, commonly known as the stomach flu, is a highly contagious stomach and intestinal infection.

Research indicates that 685 million people globally suffer from acute gastroenteritis caused by the Norovirus (1). Out of these cases, 200 million children under 5 years of age suffer from this condition, and approximately 50,000 children die annually. While most cases of the stomach flu go away on their own, it is a good idea to follow some home remedies to treat it effectively. Scroll down to know more!

Note: If the symptoms of gastroenteritis persist beyond a week, consult a healthcare provider immediately.

Fun Fact

Even though gastroenteritis is also known as the stomach flu, it is actually not flu as it is not caused by the influenza virus.

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.

A study conducted on 3,894 members found the prevalence of acute gastroenteritis was at 10.4% in the 30-day period, while diarrhea alone affected 7.6%. Acute gastroenteritis and diarrhea had an annual rate of 1.27 cases per person per year and 0.92 per person per year respectively.

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 most common symptoms are nausea, vomiting, and diarrhea. Dr. Jesse P. Houghton, MD, FACG, and Medical Director of Gastroenterology at the Southern Ohio Medical Center, adds, “However, abdominal cramping is often associated with these symptoms, especially during periods of vomiting. Rarely, the pain can be significant.”

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

Jeremy Puma, a blogger, had an unfortunate and painful ordeal with gastroenteritis. He had initially mistaken his symptoms for a hangover after a night of drinking but soon realized it was something far worse. He said, “This time, it was the whole nine yards (or however many yards long your digestive tract is), and multiple trips up and down the stairs to the basement bathroom so as not to inconvenience the other guests. Once the chills and aches started kicking in, I knew what was really going on (i).”

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. Should you or your little one show any signs of gastroenteritis, visit a doctor immediately. Any delay may cause further complications. Learn more in the next section.

Complications Of Gastroenteritis

If left untreated, gastroenteritis can lead to further complications in the body. The most common complications are (2):

• This is the most frequent, underestimated, and dangerous complication.
• Metabolic acidosis. This is the buildup of acid in the body due to kidney damage or failure.
• Electrolyte imbalances (hypernatraemia, hyponatremia, hypokalaemia).
• Lactose or glucose intolerance.
• Food sensitivities or intolerance.
• Hemolytic uraemic syndrome.
• Iatrogenic (caused by medical treatment) complications due to disproportionate intravenous fluids.
• Death, in severe cases.

Now that you know that gastroenteritis is not to be taken lightly, let us look at how this condition may be diagnosed.

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.
