Gastroenteritis, often referred to as the stomach flu or stomach bug, is a common condition characterized by inflammation of the gastrointestinal tract. While it is typically not serious and resolves on its own, knowing the key signs and symptoms can help you identify and manage the condition effectively. In this comprehensive guide from wellhealthorganic.com, we’ll explore the key signs of gastroenteritis and provide insights into its causes, treatment, and prevention.

Understanding Gastroenteritis:

Gastroenteritis is an umbrella term used to describe inflammation of the stomach and intestines, typically caused by viral or bacterial infections. It can lead to symptoms such as diarrhea, vomiting, abdominal pain, and nausea. While anyone can develop gastroenteritis, it is most common in children and older adults, as well as individuals with weakened immune systems.

Key Signs of Gastroenteritis:

  1. Diarrhea: One of the hallmark symptoms of gastroenteritis is diarrhea, characterized by frequent, loose, and watery bowel movements. The stool may also contain blood or mucus in some cases.
  2. Vomiting: Along with diarrhea, vomiting is another common symptom of gastroenteritis. It can occur suddenly and may be accompanied by nausea or stomach cramps.
  3. Abdominal Pain: Abdominal pain or cramping is often experienced during gastroenteritis and may vary in severity. The pain is typically located in the lower abdomen and may be accompanied by bloating or discomfort.
  4. Nausea: Many individuals with gastroenteritis experience feelings of nausea, which may precede vomiting or occur independently. Nausea can range from mild to severe and may be exacerbated by certain foods or activities.
  5. Fever: A low-grade fever is common during gastroenteritis, especially if the underlying cause is a viral infection. The fever is usually mild and may accompany other symptoms such as diarrhea and vomiting.
  6. Dehydration: Prolonged diarrhea and vomiting can lead to dehydration, characterized by symptoms such as dry mouth, increased thirst, dark urine, and fatigue. Dehydration can be particularly concerning in young children and older adults.
  7. Loss of Appetite: Gastroenteritis can cause a temporary loss of appetite due to nausea, abdominal discomfort, and digestive disturbances. Individuals may find it challenging to eat or drink, further contributing to dehydration.

Causes of Gastroenteritis:

Gastroenteritis can be caused by a variety of factors, including:

  • Viral Infections: Viruses such as norovirus, rotavirus, and adenovirus are common causes of viral gastroenteritis, especially in children.
  • Bacterial Infections: Bacteria such as Salmonella, Escherichia coli (E. coli), and Campylobacter can cause bacterial gastroenteritis, often as a result of consuming contaminated food or water.
  • Parasitic Infections: Parasites like Giardia and Cryptosporidium can also lead to gastroenteritis, typically through the ingestion of contaminated food or water.

Treatment and Management:

Treatment for gastroenteritis focuses on relieving symptoms and preventing complications such as dehydration. This may include:

  • Fluid Replacement: Drinking plenty of fluids, including water, oral rehydration solutions, and clear broths, to prevent dehydration and restore electrolyte balance.
  • Rest: Getting adequate rest and allowing the body to recuperate from the illness.
  • Dietary Modifications: Gradually reintroducing bland, easy-to-digest foods such as bananas, rice, applesauce, and toast (BRAT diet) as tolerated.
  • Medications: Over-the-counter medications such as anti-diarrheal agents or antiemetics may be recommended in certain cases, but they should be used with caution and under medical supervision.

Prevention Strategies:

Preventing gastroenteritis involves practicing good hygiene and food safety habits, including:

  • Hand Hygiene: Washing hands thoroughly with soap and water, especially after using the bathroom, changing diapers, and before preparing or consuming food.
  • Food Safety: Ensuring proper food handling, storage, and preparation to minimize the risk of contamination and foodborne illnesses.
  • Water Quality: Drinking safe, clean water and avoiding untreated or contaminated water sources, especially when traveling to areas with poor sanitation.
  • Vaccination: Following recommended vaccination schedules, particularly for children, to protect against certain viral and bacterial causes of gastroenteritis.

Gastroenteritis means inflammation in your stomach and intestine. Inflammation makes these organs feel swollen and sore. It causes symptoms of illness, like nausea, vomiting, abdominal pain and diarrhea.

Gastroenteritis often happens when you get an infection in your gastrointestinal (GI) tract. Bacteria and viruses can cause food poisoning and stomach flu infections. Chemicals can also cause gastroenteritis.

Types of gastroenteritis

Infectious gastroenteritis is the most common type. It’s caused by an infection in your gastrointestinal tract (your stomach and/or intestines). Viruses, bacteria, fungi or parasites may cause the infection.

Chemical gastroenteritis can happen if you ingest toxic chemicals, which can contaminate food and water sources. You can also get it from heavy doses of alcohol or drugs, including some medications.

How common is this condition?

Just about everyone gets gastroenteritis, likely more than once. Most of the time, it’s not serious. But in more vulnerable populations, it can be. Around the world, gastroenteritis is a leading cause of death.

Symptoms and Causes

Common symptoms of gastroenteritis include diarrhea, nausea and vomiting.
Gastroenteritis affects your stomach and intestines, causing symptoms like nausea, vomiting and diarrhea.

What are the signs and symptoms of gastroenteritis?

Symptoms involving your intestines (diarrhea, cramps), together with symptoms involving your stomach (nausea, vomiting) are the hallmarks of gastroenteritis. You’ll know it if it’s “coming out both ends.”

Gastroenteritis symptoms may include:

  • Diarrhea.
  • Nausea and vomiting.
  • Loss of appetite.
  • Abdominal pain and cramping.
  • Fever.
  • Chills.
  • Fatigue.
  • Body aches.

What are the first signs of gastroenteritis?

Gastroenteritis symptoms often come on suddenly. Gastrointestinal symptoms appear first. You might have diarrhea, stomach pain or cramps, nausea and/or vomiting many times in a short period.

As the day goes on, you may or may not begin to experience what are called “systemic symptoms” — symptoms that affect the rest of your body. These may include fever, chills and body aches.

How long does gastroenteritis last?

The most common types of gastroenteritis only last a day or two. Your body can overcome most bacterial and viral infections on its own. Some types may last longer or need treatment to go away.

What is the main cause of gastroenteritis?

Gastroenteritis happens when your immune system activates to defend your stomach and intestines from harm. It sends inflammatory cells to help fight infections and repair injured tissues.

This is usually a temporary (acute) response to a temporary threat or injury. It takes a short time to work, and then, the inflammation goes away. Longer-lasting (persistent) gastroenteritis is unusual.

What are the specific causes of acute gastroenteritis?

Infectious diseases or toxic chemicals can trigger acute gastroenteritis.

Infectious diseases

Infectious gastroenteritis is caused by an infection in your gastrointestinal tract, like a:

  • Viral infection.
  • Bacterial infection.
  • Parasitic infection.
  • Fungal infection.

Infections are the most common cause of acute gastroenteritis.

Viral gastroenteritis

Viral infections cause viral gastroenteritis, which is the most common type overall. Viruses cause 60% of all gastroenteritis cases. Norovirus alone accounts for 50% of all viral gastroenteritis cases.

Viral gastroenteritis sometimes goes by the nickname, “stomach flu,” although this isn’t a medical term. Influenza (flu) viruses don’t cause viral gastroenteritis. Viruses that can cause “stomach flu” include:

  • Norovirus.
  • Rotavirus.
  • Astrovirus.
  • Adenovirus.
  • Calicivirus.
  • Sapovirus.
Bacterial gastroenteritis

Bacterial infections cause bacterial gastroenteritis. Common bacterial gastrointestinal infections include:

  • Campylobacter.
  • Clostridioides difficile (C. diff).
  • Escherichia coli (E. coli) .
  • Salmonella.
  • Shigella.
  • Staphylococci (Staph).
Parasitic gastroenteritis

Parasite infections cause parasitic gastroenteritis. Common parasite infections include:

  • Giardiasis .
  • Cryptosporidiosis .
  • Cyclosporiasis.
  • Amebiasis (amoebic dysentery).
Fungal gastroenteritis

Fungal infections can cause fungal gastroenteritis. The most common fungal infections are:

  • Candidiasis.
  • Aspergillosis.
Chemical gastroenteritis

Chemicals can injure and inflame the lining of your stomach and intestines. Some chemicals do this even in small amounts. Others, like alcohol and certain medications, can cause gastroenteritis in larger doses.

Causes of chemical gastroenteritis include:

  • Heavy metal poisoning.
  • Plant toxins, like poisonous mushrooms.
  • Cocaine.
  • Chemotherapy drugs.
  • Alcohol overuse.
  • NSAIDs overuse.
  • Colchicine overuse.
  • Digoxin overuse.

Is gastroenteritis contagious?

Infectious gastroenteritis is contagious. When you have an infection in your gastrointestinal system, it infects your poop. Infections can spread from your poop to anyone who comes into contact with it.

Microscopic traces of poop can linger on bathroom surfaces, diaper changing areas and people’s hands if they don’t wash well. These traces can transfer to others who touch them, or to their food or water.

Chemical gastroenteritis isn’t contagious. But it can affect many people in one place at one time. If you get toxic poisoning from food, water or your environment, others sharing those things may also get it.

How do you catch gastroenteritis infections?

The most common way to get a gastrointestinal infection is from contaminated food or water. You can also catch it by touching an infected person, or by touching a surface that an infected person touched.

How long is gastroenteritis contagious?

Gastrointestinal infections are most contagious during the period when you have symptoms, and for two days after. These last two days are when your body is shedding the infection through your poop.

What are the risk factors for getting gastroenteritis?

Just about everyone gets gastroenteritis. But you’re more likely to get it more frequently if you:

  • Are older than 65 or younger than 6.
  • Live or work in a childcare or nursing home.
  • Eat raw fish or meat.
  • Travel abroad, especially in less developed regions.
  • Have a chronic condition that weakens your immune system.
  • Use certain drugs or alcohol frequently.

What are the possible complications of acute gastroenteritis?

Most of the time, gastroenteritis is brief and ends by itself. When this is the case, the primary complication to look out for is dehydration. This is more of a risk for children and senior citizens.

When you’re having frequent diarrhea or vomiting, you’re losing a lot of fluids and electrolytes. If you can’t replace them fast enough, you could become dehydrated and develop electrolyte imbalances.

If gastroenteritis lasts a long time, it could begin to damage your stomach and intestines. For example, you might develop ulcers in your organs that bleed. Only a few types of gastroenteritis can last longer.

Some specific causes of gastroenteritis can have their own side effects. These are separate from the effects of gastroenteritis itself. Certain infections or toxins can do more lasting damage to your body.

People with weakened immune systems and people with less access to clean water, nutrition, sanitation and healthcare are more vulnerable to gastroenteritis. They might get it more often, and for longer.

Children in less developed countries and senior citizens in long-term care facilities are more at risk of serious complications from gastroenteritis. This is because their health status is lower to begin with.

Diagnosis and Tests

How is gastroenteritis diagnosed?

Healthcare providers can usually recognize gastroenteritis by your symptoms. They’ll ask you when your symptoms started and what was going on at the time that could have triggered them.

If you have unusual symptoms, or if they want to investigate your symptoms further, they may order some tests. A poop test or blood test can help prove gastroenteritis and rule out other conditions.

Management and Treatment

What is the best way to get rid of gastroenteritis?

In most cases, gastroenteritis goes away by itself. The best way to help your body recover is to give it lots of rest and fluids. You might want to stick with bland, easy-to-digest foods for a few days.

But certain, less common causes of gastroenteritis do need treatment. If your symptoms don’t seem to be going away, or you believe you have a type of toxic poisoning, tell a healthcare provider.

What is the medical treatment for gastroenteritis?

Most of the time, medical treatment for gastroenteritis is supportive. That means the treatment supports your body’s natural healing process rather than curing gastroenteritis. It might include:

  • IV fluids to prevent or correct dehydration and electrolyte imbalances.
  • Parenteral nutrition to give your body energy without using your stressed digestive system.
  • Medications to treat symptoms like nausea and diarrhea, in certain cases.

But some causes of acute gastroenteritis may need medication to go away. For example, you may need a specific antibiotic or antiparasitic medication to treat a specific type of bacterial or parasite infection.

If you have chemical gastroenteritis due to toxic poisoning, you may need additional treatment to help clear the toxin out of your body. The treatment will depend on the toxin and on your condition.

How soon will I feel better?

You should feel better within two to three days after your symptoms first started, or after you started medication if you needed it. If you aren’t feeling better yet, let your healthcare provider know.

Prevention

Can gastroenteritis be prevented?

Not every case of gastroenteritis is preventable. But there’s a lot we can do to reduce our personal risk and prevent common gastrointestinal infections from spreading in our communities. For example:

  • Good hand washing. Good hand washing is one of the most important and easiest ways to protect yourself and others from infections. Lathering with soap for at least 20 seconds removes germs and toxins from your hands that might transfer to your mouth or to other people.
  • Good cleaning. Diligent cleaning is especially important in community places like schools, daycares, nursing homes and hospitals, where many people use the same facilities every day. Cleaning with disinfectants can help remove germs that may linger on common surfaces.
  • Safe food handling. Food can become contaminated at any stage of production, from harvesting and storage to cooking and preparation. Remember to wash your hands before and after handling food. Wash, refrigerate, freeze, cook and serve food according to food safety guidelines.
  • Safe travels. It’s especially easy to get food poisoning while traveling abroad. (This is called traveler’s diarrhea.) You may be exposed to microorganisms there that you wouldn’t meet at home. When traveling, it’s best to stick to cooked, peeled or packaged foods and bottled water.
  • Safe substance use. Only use drugs as directed. If you feel like your medications aren’t doing enough as directed, or you’re self-medicating with substances, see a healthcare provider for a better long-term treatment plan. If you have a substance use disorder, treatment can help.

Conclusion:

Gastroenteritis is a common condition characterized by inflammation of the gastrointestinal tract, typically caused by viral, bacterial, or parasitic infections. Recognizing the key signs and symptoms of gastroenteritis is crucial for prompt diagnosis and management. By understanding its causes, treatment options, and prevention strategies, individuals can take proactive steps to mitigate the impact of gastroenteritis on their health and well-being. If you or a loved one experience symptoms of gastroenteritis, it’s essential to seek medical advice for appropriate evaluation and care.
