What Causes Intestinal Infections
Intestinal infection may be caused by a virus, bacteria, or parasites.
- Virus: Viral gastroenteritis or stomach flu is one of the most common causes of intestinal infections. It can easily spread from an infected person when sharing food or beverages, even if the infected person does not have symptoms. Common causes of viral gastroenteritis include:
- Astrovirus
- Sapovirus
What Causes H Pylori Infections
Its still not known exactly how H. pylori infections spread. The bacteria has coexisted with humans for many thousands of years. The infections are thought to spread from one persons mouth to another, like by kissing.
The bacteria may also be transferred through contact with vomit or stool. This can happen when a person does not wash their hands thoroughly after using the bathroom. H. pylori can also spread through contact with contaminated water or food.
Home Remedies For Mild Cases
If you have a milder case, you may be able to treat your illness at home. Try the following:
- Drink fluids regularly throughout the day, especially after bouts of diarrhea.
- Eat little and often, and include some salty foods.
- Consume foods or drinks with potassium, such as fruit juice and bananas.
A few ingredients you may have at home can help keep your electrolytes balanced and treat diarrhea. Avoid eating dairy, fruit, or high fiber foods to keep diarrhea from getting worse.
Over-the-counter medications that neutralize your stomach acid can help. Medications that treat symptoms like diarrhea, nausea, and abdominal pain can help ease the stress and pain of the infection.
However, do not take OTC treatments unless your doctor tells you to do so. Go to the hospital if you cant keep any fluids down.
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.

Getting Medical Advice For Your Child
You don’t usually need to see your GP if you think your child has gastroenteritis, as it should get better on its own, and taking them to a GP surgery can put others at risk.
Phone the 111 service or your GP if you’re concerned about your child, or they:
- have symptoms of dehydration, such as passing less urine than normal, being unusually irritable or unresponsive, pale or mottled skin, or cold hands and feet
- have blood in their poo or green vomit
- are vomiting constantly and are unable to keep down any fluids or feeds
- have had diarrhoea for more than a week
- have been vomiting for three days or more
- have signs of a more serious illness, such as a high fever , shortness of breath, rapid breathing, a stiff neck, a rash that doesn’t fade when you roll a glass over it or a bulging fontanelle
- have a serious underlying condition, such as inflammatory bowel disease or a weak immune system, and have diarrhoea and vomiting
Your GP may suggest sending off a sample of your child’s poo to a laboratory to confirm what’s causing their symptoms. Antibiotics may be prescribed if this shows they have a bacterial infection.

Can I Prevent Gastroenteritis
The best way to prevent bacterial gastroenteritis is to practice good hygiene.
- Wash your hands thoroughly while handling or preparing food.
- Dont leave food out too long when youre serving it. Throw it out if theres any chance it has gone bad.
- If you learn of an outbreak of tainted food or drink through a news report, avoid consuming those items.
- Limit contact with others who have symptoms such as vomiting and/or diarrhea.
- Avoid eating undercooked food.
- Use alcohol-based hand sanitizers.
Are The Stomach Flu And Food Poisoning The Same Condition
Although the stomach flu and food poisoning share some common symptoms such as diarrhea, nausea and vomiting, stomach cramps, muscle aches, for example, they are not exactly the same condition.
- Stomach flu or gastroenteritis means any nonspecific inflammatory problem in the gastrointestinal tract some doctors consider the stomach flu to be more narrowly defined as a viral infection that attacks the digestive system.
- Food poisoning specifically is caused by eating or drinking contaminated food or fluid that contains bacteria, viruses, parasites and/or their toxins they produce.
Consequently, there is some crossover between the two terms.
In addition:
- Food poisoning usually is found in small outbreaks that occur among individuals that have ingested the same foods or drink, and symptoms occur rapidly within hours whereas the stomach flu has a more gradual onset of symptoms and usually lasts longer than food poisoning.
- Stomach flu is highly contagious and can be spread quickly to other individuals whereas food poisoning usually requires ingesting the poison and does not easily spread to other individuals.

What Foods Are Recommended To Eat When You Have The Stomach Flu

Some health care professionals suggest a special diet for the gastroenteritis, especially for viral and/or bacterial infections in children. First and foremost is adequate fluid rehydration to prevent dehydration.
The diet frequently suggested is termed the “BRAT” diet. This diet consists of foods that are not usually irritating but soothing for the gastrointestinal tract. The BRAT diet stands for bananas, rice, applesauce and toast. Although some doctors think this diet may not markedly benefit patients, others recommend it for both adults and children for a day or two to make the transition from the resolving symptoms of acute gastroenteritis to the patient’s previously normal diet.

Symptoms Of A Fungal Stomach Infection
Yeast is a naturally-occurring fungus that is found in the mouth, intestines, and the genital region. The presence of beneficial bacteria in our body helps in controlling the population of this fungi. Prolonged use of antibiotics can disrupt the necessary balance of beneficial bacteria. This gives rise to growth of this fungi, which in turn, leads to yeast infections. Stomach or intestinal yeast infections are most likely to occur, when the immune system is compromised. Excessive intake of sugar is also a risk factor. The common symptoms of this infection include:
- Abdominal pain
- Mucus in stool
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 or changing a diaper
The most common cause of gastroenteritis is a virus. The main types are rotavirus and norovirus.
Rotavirus is the world’s most common cause of diarrhea in infants and young children. Norovirus is the most common cause of serious gastroenteritis and also foodborne disease outbreaks in the U.S.
Although not as common, bacteria such as E. coli and salmonella can also trigger the stomach flu. Salmonella and campylobacter bacteria are the most common bacterial causes of gastroenteritis in the U.S. and are usually spread by undercooked poultry, eggs, or poultry juices. Salmonella can also be spread through pet reptiles or live poultry.
Another bacteria, shigella, is often passed around in day care centers. It typically is spread from person to person, and common sources of infection are contaminated food and drinking water.
Parasites can also cause gastroenteritis, but it’s not common. You can pick up organisms such as giardia and cryptosporidium in contaminated swimming pools or by drinking contaminated water.
There are also other unusual ways to get gastroenteritis:
- Heavy metals in drinking water
- 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

Stomach Flu And Children
Children can get dehydrated quickly, so if your child has the stomach flu, it’s important that you look for signs that they are very thirsty or has dry skin or a dry mouth. If you have a baby, look for fewer, drier diapers.
Keep children with gastroenteritis out of day care or school until all symptoms are gone. 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.
To help prevent rotavirus — the most common cause of stomach flu for children — there are two vaccines that can be given to infants. Talk to your doctor about the vaccines.

Babies can continue milk feeds throughout the illness, with rehydration fluid between feeds.
Causes & Risk Factors

H. pylori causes are not many. Mainly, you can get H. pylori from person-to-person transmission by way of direct contact with the saliva, vomit or fecal matter of an infected individual. So, kissing and sharing utensils are two common ways the bacteria spreads. You can also contract H. pylori from consumption of contaminated water or food.
Childhood is actually when youre most at risk for getting H. pylori, especially under circumstances like these:
- Living with someone, like a parent, who already has H. pylori.
- A crowded living situation with many people.
- A lack of clean and reliable water.
- Your home is in a developing country where unsanitary and crowded living situations are more prevalent.
