Gastroenteritis: Symptoms, Causes, and Natural Remedies

Gastroenteritis, often referred to as the “stomach flu,” is an inflammation of the stomach and intestines. This condition can lead to a range of uncomfortable symptoms and is often caused by various factors. Understanding its symptoms, causes, and natural treatments can help manage and alleviate its effects.

Symptoms of Gastroenteritis

The symptoms of gastroenteritis can vary in severity and typically include:

  • Diarrhea: Frequent, watery stools are a common sign.
  • Nausea and Vomiting: Feeling nauseous and vomiting are typical symptoms.
  • Abdominal Pain and Cramping: Discomfort and cramps in the stomach area are common.
  • Fever: A mild fever may accompany the condition.
  • Headache and Muscle Aches: General body aches and headaches can occur.
  • Dehydration: Symptoms of dehydration include dry mouth, increased thirst, and reduced urine output.

Causes of Gastroenteritis

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

  • Viral Infections: Viruses like norovirus, rotavirus, and adenovirus are common causes.
  • Bacterial Infections: Bacteria such as E. coli, Salmonella, and Campylobacter can lead to gastroenteritis.
  • Parasitic Infections: Parasites like Giardia lamblia can cause the condition.
  • Contaminated Food or Water: Consuming contaminated food or water can introduce harmful microorganisms.
  • Poor Hygiene: Inadequate handwashing can facilitate the spread of infectious agents.
  • Close Contact with Infected Individuals: Being in close proximity to someone with gastroenteritis increases the risk of transmission.

Natural Ways to Treat Gastroenteritis

While severe cases may require medical attention, many instances of gastroenteritis can be managed with natural remedies. Here are some effective methods:

  • Stay Hydrated: Drinking plenty of fluids is crucial to prevent dehydration. Oral rehydration solutions (ORS) containing electrolytes are particularly beneficial. Coconut water is also an excellent natural option.
  • Follow the BRAT Diet: The BRAT diet (bananas, rice, applesauce, and toast) can help ease symptoms. These foods are bland and gentle on the stomach.
  • Ginger: Ginger has anti-inflammatory properties and can help reduce nausea and vomiting. Ginger tea or ginger ale (without artificial additives) are good options.
  • Peppermint: Peppermint can soothe the digestive tract and relieve cramps. Peppermint tea or diluted peppermint oil can be effective.
  • Chamomile Tea: Chamomile has calming properties and can help reduce stomach cramps and inflammation.
  • Probiotics: Probiotics, found in yogurt and fermented foods, can help restore the balance of good bacteria in the gut.
  • Apple Cider Vinegar: A mixture of apple cider vinegar and water can help balance stomach acid and combat pathogens.
  • Rest: Giving your body time to heal is crucial. Adequate rest can help your immune system fight off the infection.

Preventive Measures To Reduce the Risk of Gastroenteritis:

  • Practice Good Hygiene: Regular handwashing with soap and water is essential.
  • Cook Food Thoroughly: Ensure that food, especially meat, is cooked to the proper temperature.
  • Avoid Contaminated Water: Drink purified or bottled water, especially when traveling.
  • Clean Surfaces: Disinfect surfaces regularly, especially in the kitchen and bathroom.

When to Seek Medical Attention

While most cases of gastroenteritis can be managed at home, it’s important to seek medical help if:

Symptoms persist for more than a few days.
There is severe dehydration, characterized by very dry mouth, extreme thirst, and little or no urination.
There is blood in the stool or vomit.
A high fever persists.

expanding on the natural remedies, let’s delve deeper into how each can be utilized effectively:


  • Oral Rehydration Solutions (ORS): These can be purchased from pharmacies or made at home by mixing 1 liter of clean water with 6 teaspoons of sugar and 1/2 teaspoon of salt. This mixture helps replenish lost fluids and electrolytes.
  • Coconut Water: Rich in electrolytes like potassium, it is a natural rehydration option.
  • Herbal Teas: In addition to ginger and chamomile, teas like fennel, mint, and cinnamon can also help soothe the stomach and maintain hydration.


  • Ginger Tea: Fresh ginger can be sliced and boiled in water to make a soothing tea.
  • Ginger Capsules: Available in health stores, they can provide a concentrated dose of ginger’s active compounds.


  • Peppermint Tea: Brewed from fresh or dried leaves, it can help relax gastrointestinal muscles and reduce spasms.
  • Peppermint Oil: Adding a few drops to a diffuser or bath can provide relief through aromatherapy.

  • Yogurt: Choose plain, unsweetened yogurt with live cultures to help restore gut flora.
  • Kefir: This fermented milk drink is rich in probiotics and can be easier to digest for some people.
  • Fermented Foods: Sauerkraut, kimchi, and other fermented vegetables can help introduce beneficial bacteria to the gut.

Apple Cider Vinegar:

  • ACV Drink: Mix 1-2 tablespoons of apple cider vinegar in a glass of water and drink it before meals to aid digestion and balance stomach acidity.

BRAT Diet:

  • Bananas: High in potassium, they help replace lost electrolytes.
  • Rice: Easy to digest and provides necessary carbohydrates.
  • Applesauce: Contains pectin, which can help bind stool and reduce diarrhea.
  • Toast: Plain toast is easy on the stomach and can help with nausea.

Chamomile Tea:

  • Tea Preparation: Steep 1-2 teaspoons of dried chamomile flowers in hot water for 10 minutes. This tea can help with inflammation and provide a calming effect.


  • Importance of Rest: Adequate sleep and avoiding strenuous activities allow the body to focus energy on fighting the infection and repairing tissues.

    Additional Natural Approaches

    Activated Charcoal:

    • Usage: It can absorb toxins and may reduce symptoms of food poisoning and gas. Activated charcoal supplements are available over-the-counter.

    BRAT Variations:

    • Adding Plain Chicken: Boiled or baked chicken without seasoning can provide protein without upsetting the stomach.
    • Carrots and Potatoes: Cooked without spices, they can be gentle on the stomach and provide necessary nutrients.

    Aloe Vera Juice:

    • Anti-Inflammatory Properties: Aloe vera juice can soothe the digestive tract. Ensure the product is free from latex, which can have a laxative effect.

Staying hydrated, following a gentle diet, and using natural remedies can ease symptoms and support recovery. Practicing good hygiene and taking preventive measures can also reduce the risk of contracting gastroenteritis. If symptoms persist or worsen, it’s crucial to seek medical attention to ensure proper care and recovery.
