Wie man mit Gastroenteritis umgeht

Was verursacht Gastroenteritis?

Gastroenteritis, sometimes called stomach flu, is commonly caused by Noroviren and adenoviruses, but other viruses can also be responsible. Bacterial gastroenteritis is triggered by common bacteria such as Salmonellen, E. coli, and campylobacter, and can result from consuming contaminated food or drinks.

Symptoms can vary in severity, from a few days of mild tummy upset with vomiting and Durchfall to severe sickness and diarrhoea for several days. It's mostly harmless, especially if you are otherwise in good health. However, there can be cause for concern if young children, the elderly, pregnant people, and those with compromised immune systems have severe or persistent symptoms.

While it's unpleasant, most people recover in a few days. It's essential to take care of yourself while recovering from gastroenteritis to prevent prolonging or worsening your symptoms.

Stay at home and rest

Staying home and resting until you're better are important. Leaving your house jeopardises your own health and that of anyone you come into close contact with, as gastroenteritis is contagious.

Being sick and diarrhoea both cause dehydration, especially if you are unable to keep food and fluids down. Signs of dehydration include Schwindel, Kopfschmerzen, and other symptoms that make everyday tasks strenuous and even exhausting.

Overexerting yourself can make you feel worse and slow the recovery period. It can also be unsafe for you to leave the house when you are dehydrated, as it may affect factors such as your decision-making and balance.

Drink plenty of fluids

Repeatedly being sick and having diarrhoea make it difficult to give your body what it needs - fluids being one of them. Whether you are unable to keep fluids down or feel too unwell to drink at all, dehydration makes you feel worse and can cause other symptoms.

Symptoms of mild dehydration include:

• Schwindel.

• Kopfschmerzen.

• Dry mouth and tongue.

• Dark pee.

• Müdigkeit.

You should drink two to three litres of water daily. If you have gastroenteritis, drink more water than usual or consider using oral rehydration solutions to prevent dehydration. A rough guide for increasing water intake is an extra glass of water following bouts of diarrhoea.

Being sick makes it difficult to keep down fluids and stay hydrated. If you've been sick, wait around 5-10 minutes before drinking again, and start by drinking small amounts every few minutes. This will help your body get used to drinking without overdoing it and causing you to be sick again.

Ease back into eating

You should try to eat as normally as possible. This can be difficult as you may not have an appetite or are still being sick. Adults can handle a day or two without food, but when you start eating again, you should ease yourself back with small, light, plain meals and foods that are easy to digest - such as bread, rice, pasta, and sugar-free cereals. Try to avoid dairy products if you have an upset tummy as they can be more difficult for your body to digest.

The key is to go with your appetite - if you're hungry, try to eat. Even small amounts of food will help your intestinal lining heal and provide the energy to regain your strength and recover. However, if you begin to feel nauseous or are sick, you should lower your food intake.

Here's a guide for eating when you have gastroenteritis.

Avoid spreading infection at home

An important part of recovering from gastroenteritis is ensuring it doesn't spread to other people. Hygiene precautions help to prevent others getting sick and you experiencing repeat bouts of gastroenteritis.

Here are some good hygiene practices to keep in mind when you or someone else at home has gastroenteritis:

• Stay at home until you haven't vomited or had an episode of diarrhoea for at least 48 hours.

• Thoroughly wash your hands with soap and water after using the toilet. Dry your hands properly.

• Using disinfectant, clean the toilet and any surfaces that may have been touched, including larger surfaces as well as small surfaces, such as taps and door handles.

• Don't share towels.

• Don't make or serve food for other people.

Monitor medicines

If you take daily medicines, it's crucial to monitor your intake, as bouts of sickness could mean you're not getting the right dosage.

Generally, if you're sick more than 20 minutes after taking your medicine, it's unlikely you'll need to take more. But to be safe, contact your doctor for advice as all medicines vary with regard to dosage and side-effects.

Certain types of medicines have "sick rules". If this is the case, make sure you have the sick rules written down and let your doctor know you have changed your medicine dose or intake because you have been ill. If you are in doubt, seek advice immediately.

It's better to take paracetamol for pain relief, as ibuprofen can irritate your stomach.
