Gastroenteritis is an infection or inflammation of the stomach and intestines that can cause diarrhea, vomiting and other digestive problems. It is commonly known as the “stomach flu,” although it is not related to influenza.
Gastroenteritis is usually caused by a viral or bacterial infection. In some cases, parasites, contaminated food or water, certain medicines or other irritants can also cause similar symptoms.
With proper care and enough fluids, most mild cases improve within a few days. However, severe diarrhea and vomiting can lead to dehydration and may require medical attention.
Symptoms of Gastroenteritis
The symptoms of gastroenteritis can vary depending on the cause and severity of the infection. Common symptoms include:
- Watery diarrhea
- Vomiting
- Nausea
- Stomach pain
- Abdominal cramps
- Fever
- Headache
- Weakness and tiredness
Diarrhea and vomiting can cause the body to lose a significant amount of water and electrolytes. This can result in dehydration, especially in young children, older adults and people with other health conditions.
Signs of Dehydration and Stomach Flu and Children
Children can get dehydrated quickly, so if your child has the stomach flu, it is important that you look for signs that they are very thirsty or has dry skin or a dry mouth. Check with your doctor before giving your child any medicine. Drugs used to control diarrhea and vomiting aren’t usually given to children younger than 5.
Watch for symptoms such as:
- Very dry mouth
- Dry skin
- Increased thirst
- Dizziness or lightheadedness
- Reduced urination
- Weakness or unusual tiredness
If dehydration becomes severe, medical attention should be sought promptly.
What Causes Gastroenteritis?
There are many ways gastroenteritis can be spread:
- Contact with someone who has the virus
- Contaminated food or water
- Unwashed hands after going to the bathroom
- The most common cause of gastroenteritis is a virus. The main types are rotavirus and norovirus
Viral Gastroenteritis
Viruses are among the most common causes of gastroenteritis. Norovirus and rotavirus are important causes of viral gastroenteritis.
Rotavirus is a common cause of diarrhea in infants and young children. Vaccination can help protect children against rotavirus infection.
Bacterial Gastroenteritis
Bacteria such as E. coli, Salmonella, Shigella and Campylobacter can also cause gastroenteritis.
These infections may spread through contaminated food or water or through poor hygiene.
Salmonella and Campylobacter infections can be associated with undercooked poultry, eggs and contaminated food products. Salmonella can also spread through contact with some animals, including reptiles and live poultry.
Shigella can spread easily from person to person, particularly in settings such as childcare facilities. Contaminated food and drinking water can also be sources of infection.
Parasitic Gastroenteritis
Parasites can also cause gastroenteritis, although this is less common. Organisms such as Giardia and Cryptosporidium may spread through contaminated water or contaminated swimming pools.
Other Possible Causes
In some cases, symptoms similar to gastroenteritis may occur because of other factors, such as:
- Eating large amounts of acidic foods
- Certain seafood toxins
- Antibiotics and other medicines
- Some antacids or laxatives
- Certain chemotherapy medicines
A doctor can help determine the possible cause based on the symptoms, medical history and, when necessary, diagnostic tests.
There are also other unusual ways to get gastroenteritis:
- Eating a lot of acidic foods, like citrus fruit and tomatoes Toxins that might be found in certain seafood
- Medications such as antibiotics, antacids, laxatives, and chemotherapy drugs Gastroenteritis Treatment
Prevent dehydration:
Give a child an oral rehydration solution. Call your doctor for age-appropriate dosing specifics. Give an adult as much clear fluid as possible. The person should drink fluids slowly in frequent, small amounts. Drinking too much too fast can make nausea worse.
As symptoms start to ease:
- Gradually ease food back into the person's diet
- Avoid dairy, raw vegetables & salad, milk, caffeine, and alcohol until recovery is complete
- Start with bland, easy-to-digest food such as c bananas, toast, rice, and khichri
When to call a doctor
Contact emergency if the person is in shock from severe dehydration (faints, can’t walk, is confused, or is having trouble breathing)
Gastroenteritis Treatment
The main aim of gastroenteritis treatment is to prevent dehydration and help the body recover.
Preventing Dehydration
For children, an oral rehydration solution (ORS) can help replace fluids and electrolytes lost through diarrhea and vomiting. The appropriate amount depends on the child’s age and condition, so parents should consult a doctor when needed.
Adults should drink plenty of clear fluids. It is usually better to take small amounts frequently rather than drinking a large quantity at once, as drinking too quickly may worsen nausea or vomiting.
Food During Recovery
As symptoms begin to improve, food can gradually be added back to the diet.
It may help to:
- Eat small and frequent meals
- Choose light and easy-to-digest foods
- Try foods such as bananas, toast, rice and khichri
- Drink enough fluids
Until recovery is complete, it may be better to avoid:
- Alcohol
- Caffeine
- Milk and some dairy products
- Raw vegetables and salads
- Heavy or oily foods
Treatment depends on the cause and severity of gastroenteritis. Antibiotics are not useful for most viral infections and should only be taken when prescribed by a doctor for an appropriate bacterial infection.
When Should You See a Doctor?
Most mild cases of gastroenteritis improve with adequate fluids and rest. However, you should consult a doctor if symptoms are severe, persistent or getting worse.
Seek medical help if there is:
- Severe or persistent vomiting
- Frequent or severe diarrhea
- Signs of dehydration
- Severe abdominal pain
- High or persistent fever
- Blood in stool or vomit
- Very little or no urination
- Severe weakness or dizziness
When Is Gastroenteritis an Emergency?
Severe dehydration can become a medical emergency. Seek immediate medical attention if a person:
- Faints
- Becomes confused
- Is unable to stand or walk properly
- Has severe weakness
- Has difficulty breathing
- Shows signs of shock
Children, older adults and people with existing medical conditions may be at greater risk of complications from dehydration and should be evaluated promptly when symptoms are severe.
