wellhealthorganic.com : key signs of gastroenteritis

Gastroenteritis, commonly known as the stomach flu or gastric flu, is a prevalent condition characterized by inflammation of the stomach and intestines. While it often resolves on its own, understanding its key signs and symptoms is crucial for prompt diagnosis and appropriate treatment. Let’s delve into the world of gastroenteritis, exploring its symptoms, causes, and management options, as found on wellhealthorganic.com.

Understanding Gastroenteritis:

Gastroenteritis is typically caused by viral, bacterial, or parasitic infections, although it can also result from consuming contaminated food or water. The condition is characterized by inflammation of the gastrointestinal tract, leading to symptoms such as nausea, vomiting, diarrhea, abdominal pain, and fever. While gastroenteritis is often referred to as the “stomach flu,” it is distinct from influenza, which primarily affects the respiratory system.

Key Signs and Symptoms:

  1. Nausea and Vomiting: One of the hallmark symptoms of gastroenteritis is nausea, often accompanied by vomiting. These symptoms result from irritation of the stomach lining and may occur shortly after eating or drinking contaminated food or water.
  2. Diarrhea: Diarrhea is another common symptom of gastroenteritis, characterized by loose, watery stools. The inflammation of the intestines leads to increased bowel movements and difficulty in controlling bowel movements, which can contribute to dehydration if not adequately managed.
  3. Abdominal Pain: Many individuals with gastroenteritis experience abdominal pain or cramping, which can range from mild to severe. This discomfort is often localized in the lower abdomen and may be exacerbated by eating or drinking.
  4. Fever: Gastroenteritis can cause fever, which is your body’s natural response to infection. A low-grade fever is common in individuals with gastroenteritis, although some may experience higher temperatures depending on the severity of the infection.
  5. Dehydration: Prolonged vomiting and diarrhea can lead to dehydration, a potentially serious complication of gastroenteritis. Signs of dehydration include dry mouth, increased thirst, decreased urine output, and lightheadedness. In severe cases, dehydration may require medical intervention.

Causes and Risk Factors:

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

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

Treatment and Management:

The treatment of gastroenteritis typically focuses on relieving symptoms and preventing dehydration. This may involve:

  • Fluid Replacement: Drinking plenty of fluids, such as water, electrolyte solutions, or clear broth, to replace lost fluids and electrolytes.
  • Rest and Nutrition: Resting and avoiding solid foods until symptoms improve, gradually reintroducing bland, easy-to-digest foods as tolerated.
  • Medications: Over-the-counter medications such as antiemetics (to reduce nausea and vomiting) and antidiarrheal agents (to alleviate diarrhea) may be recommended in certain cases.
  • Medical Evaluation: Seeking medical attention if symptoms are severe or persistent, especially in young children, older adults, or individuals with weakened immune systems.

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:

In conclusion, understanding the key signs of gastroenteritis is essential for prompt diagnosis and appropriate management of this common gastrointestinal condition. By recognizing the symptoms, causes, and treatment options associated with gastroenteritis, individuals can take proactive steps to alleviate discomfort, prevent complications, and promote recovery.
