If you have bacterial gastroenteritis, you may also experience symptoms that include:
- vomiting
- severe abdominal cramps
- diarrhea
While viruses cause many gastrointestinal infections, bacterial infections are also common. Some people call these infectionsfood poisoning.
Infection can occur after close contact with animals. You can also acquire an infection by consuming food or water contaminated by bacteria, or the toxic substances produced by bacteria.

Treatment is meant to keep you hydrated and avoid complications. It’s important to not lose too many nutrients, such as sodium andpotassium. Your body needs these in certain amounts in order to function properly.
If you have a serious case of bacterial gastroenteritis, you may be admitted to the hospital and givenfluidsand saltsintravenously.
Antibiotics are usually reserved for the most severe cases.
Home remedies for mild cases
If you have a milder case, you may be able to treat your illness at home. Try the following:

Many bacteria can cause gastroenteritis, including:
- Yersinia, found in pork
- Staphylococcus, found in dairy products, meat, and eggs
- Shigella, found in water and often swimming pools
- Salmonella, found in meat, dairy products, and eggs
- Campylobacter, found in meat and poultry
- E. coli, found in ground beef and salads
Bacterial gastroenteritis outbreaks can happen when restaurants serve contaminated food to many people. An outbreak can also trigger recalls of produce and other foods.
Bacteria that cause gastroenteritis can be easily transmitted from person to person if someone carries the bacteria on their hands.
Every time a person with a bacterial infection touches food, objects, or other people, the bacteria have a chance to be passed on to others. The bacteria can even be spread through your own body if you touch your eyes, mouth, or other open parts of your body with hands that already have an infection.
You’re especially at risk of these infections if you travel a lot or live in a densely populated area. Washing your hands often and using hand sanitizer with more than 60 percent alcohol can help you avoid contracting infections from other people and your surroundings.
Specific strains of bacteria can cause several types of intestinal infections.
Yersiniosis
The
Yersiniosis symptoms can occur 4 to 7 days after you’re exposed. They may include:
- fever
- stomach pain
- diarrhea
Staph food poisoning
Foods that are contaminated withStaphylococcus aureusbacteria can causestaph food poisoning. These include:
- meat
- eggs
- dairy products
Staph poisoning causes symptoms like nausea, vomiting, and stomach cramps, according to the
If you do get staph food poisoning, know that severe illness is uncommon and symptoms don’t usually last longer than a day.
Shigellosis
The
Typically,shigellosissymptoms begin 1 day after infection and can last up to 7 days. They include:
- fever
- stomach cramps
- diarrhea
Although most people don’t need antibiotics, they can help shorten the duration of symptoms. Your doctor may recommend them if you have a weakened immune system.
Salmonellosis
Salmonellosisis a common infection that occurs when you eat foods contaminated withSalmonellabacteria. These may include:
- meat
- eggs
- dairy products
- certain vegetables, such as sprouts
The
Salmonellosis usually causes symptoms like cramps, fever, and diarrhea. They can occur between 6 hours and 6 days after infection and may last up to 1 week.
Campylobacteriosis
This typeof intestinal infection is caused by theCampylobacterbacteria, the
Generally, symptoms begin 2 to 5 days after infection. They include:
- fever
- stomach cramps
- nausea

E. coli infection
According to the
If you have anE. coli感染,你可能已经像抽筋症状,diarrhea, and vomiting. These usually start about 3 to 4 days after you’re exposed.
Although mostE. coliinfections are mild, certain strains can cause serious complications which may require hospitalization.
Therefore, talk with your doctor if you:
- are unable to keep down liquids
- have bloody diarrhea
- experience diarrhea that lasts for more than 3 days and is accompanied by a high fever
If you already have gastroenteritis, take safety precautions to avoid transmitting the bacteria to others:
- Wash your hands after using the toilet and before handling food.
- Do not prepare food for other people until symptoms improve.
- Avoid close contact with others during your illness.
- Try to wait at least 48 hours before returning to work after your symptoms stop.
You can also help prevent infections by avoiding unpasteurized milk and raw meat or shellfish. Use separate cutting boards and utensils for raw and cooked meats, and wash salads and vegetables thoroughly. Make sure to store foods at either very hot or very cold temperatures if you’re storing them for more than a few hours.
To take other preventive measures, you can:
- Keep your kitchen consistently clean.
- Wash your hands after using the toilet, before handling different foods, after touching animals, and before eating.
- Drink bottled water while traveling abroad and get your recommended vaccines.
If you have a weakened immune system because of an existing condition or treatment, you may have a higher risk of bacterial gastroenteritis. The risk also increases if you take drugs that decrease your stomach’s acidity.
Handling food incorrectly can also raise your risk of bacterial gastroenteritis. Food that’s undercooked, stored too long at room temperature, or not reheated well can aid in the spread and survival of bacteria.
Bacteria can produce harmful substances known as toxins. These toxins can remain even after reheating food.
Your doctor will ask questions about your illness and check for signs of dehydration and abdominal pain, as recommended in a
Your doctor may also take a blood sample to check for dehydration.
Bacterial gastroenteritis rarely causes complications in healthy adults and usually lasts less than a week.
Older adults or very young children are more vulnerable to the symptoms of gastroenteritis. They’re also at a higher risk of complications. If you have a loved one at a higher risk, keep a close eye on them so they can get medical care if they need it.
Complications of these infections include high fevers,muscle pain, and inability to control your bowel movements. Some bacterial infections can cause:
- kidney failure
- bleeding in your intestinal tract
- anemia
Quickly seeking treatment for bacterial gastroenteritis lessens your risk of complications.
Children can be more prone to bacterial gastroenteritis than adults.
For example, a
MostSalmonellainfections happen when children consume contaminated food or water or come into contact with animals that carry the bacteria.
Young children are also more likely to get infections fromClostridium difficile. These bacteria are mostly found in dirt and animal feces.
Children are more likely to develop infections from these types of bacteria. However, like adults, children are susceptible to any bacterial infections.
Make sure that children practice good hygiene, wash their hands regularly, and avoid putting their hands in their mouths or near their eyes. Wash your own hands after changing a baby’s diaper.
Wash and prepare food for children thoroughly, cooking raw dishes like eggs, vegetables, and meat until they’re well done.
Many symptoms of bacterial infection in children are the same as
One unique symptom of these infections in children is a dry diaper. If a child hasn’t needed a diaper change for over 6 hours, they may be dehydrated.
Talk with your doctor right away if your child or a child in your care has any of these symptoms. If they have diarrhea or other related symptoms, make sure they drink plenty of fluids.
After seeking treatment or medical care, get plenty of rest to help your body recover from the infection.
If you have diarrhea or vomiting, drink plenty of liquids to keep yourself hydrated. Avoid dairy or fruit, which can make diarrhea worse. Sucking on ice cubes can help if you can’t keep food or water down.
Many bacterial infection outbreaks result from contaminated food making its way to grocery stores and then being sold to consumers. Keep up on news stories about public outbreaks and checkcertain foodsfor contamination.
Bacterial gastroenteritis usually lasts for 1 to 3 days. In some cases, infections can last for weeks and be harmful if left untreated.
Seek treatment as soon as you show symptoms of an infection to stop the infection from spreading. With good medical care and proper treatment, your infection will likely go away in a few days.
