What is Gastro?

Gastroenteritis, more commonly known as gastro, is an infection of the gastrointestinal system that can cause nausea, vomiting, diarrhea, and abdominal cramps. It can be caused by a variety of things, including bacteria, viruses, or parasites, and is most commonly transmitted through contaminated food or water.

Gastro can be a very unpleasant experience, and it’s important to know how to treat it properly to avoid worsening the symptoms or spreading it to others. Here’s everything you need to know about gastro and how to deal with it.

Symptoms of Gastro

The most common symptoms of gastro are nausea, vomiting, diarrhea, and abdominal cramps. These symptoms can range from mild to severe, and may be accompanied by a fever, chills, or a headache. Some people may also experience loss of appetite, fatigue, or muscle aches.

Gastro can last anywhere from a few days to a week, depending on the severity of the infection and how quickly it is treated. It’s important to pay attention to your body and listen to your doctor’s recommendations to ensure that you get the proper treatment and rest.

Causes of Gastro

Gastro can be caused by a variety of things, including bacteria, viruses, or parasites.

Bacterial gastro is usually caused by contaminated food or water, and can be spread through poor hygiene practices or consuming undercooked meat or seafood

Viral gastro is usually caused by a virus, such as the norovirus, and can be spread through contact with infected people or surfaces.

Parasitic gastro is caused by parasites and is usually transmitted through contaminated food or water.

It’s important to practice good hygiene, such as washing your hands frequently and thoroughly cooking your food, to reduce the risk of getting gastro.

Treatment for Gastro

The most important thing to do when dealing with gastro is to stay hydrated. Gastro can cause your body to lose fluids, so it’s important to replace those fluids through drinking water or electrolyte-rich drinks like sports drinks or oral rehydration solutions.

It’s also important to avoid solid foods while you have gastro, as they can be difficult to digest and may worsen your symptoms. Instead, focus on consuming clear liquids like broth, water, or electrolyte drinks. As your symptoms start to improve, you can gradually reintroduce solid foods into your diet.

Over-the-counter medications like loperamide (Imodium) can be helpful in reducing diarrhea, but it’s important to speak with your doctor before taking any medications. Antibiotics may be necessary for bacterial gastro, but they are not effective against viral gastro.

It’s also important to get plenty of rest while you have gastro. This will give your body the opportunity to focus on fighting the infection and recovering.

Preventing Gastro

To prevent the spread of gastro, it’s important to practice good hygiene and avoid contaminated food and water. Wash your hands frequently, especially after using the bathroom, changing a diaper, or handling raw meat or seafood.

If you have gastro, it’s important to stay home and avoid close contact with others until your symptoms have completely cleared up. This will help prevent the spread of the infection to others.

It’s also important to properly store and prepare food to prevent the spread of gastro. Foods should be stored at the appropriate temperature and cooked thoroughly to kill any bacteria or parasites.
