What Causes Acute Diarrhea? A Guide from Bali International Hospital

Acute diarrhea is a common health problem, especially in Indonesia, and it can affect anyone. This condition involves frequent loose or watery stools, and it can be caused by various factors, most often linked to infections from viruses, bacteria, or parasites.

At our international hospital, we want to help you understand the causes of acute diarrhea, its risk factors, and how to prevent it. Acute diarrhea refers to sudden and frequent watery stools.

It often comes with symptoms like nausea, vomiting, fever, and stomach cramps. In most cases, it lasts for a short time, but if untreated, it can cause dehydration, especially in children and the elderly.

Dehydration can be serious, making it important to stay hydrated and seek medical help when needed. If you find yourself in need of immediate assistance, our emergency room is equipped to handle urgent care situations.

In Indonesia, the main causes of acute diarrhea are infections from viruses, bacteria, and parasites. These infections spread through contaminated food, water, and poor hygiene, making it a bigger problem in areas with limited access to clean water and sanitation.

Virus Causes of Acute Diarrhea

Viruses are the leading cause of diarrhea, particularly in children. The most common viral agents are rotavirus and norovirus.

Rotavirus

Rotavirus is the most common cause of severe diarrhea in young children. It spreads through contaminated food, water, or surfaces and is highly contagious.

It can cause dehydration, which makes it dangerous for young children. Fortunately, a vaccine is available that can protect against rotavirus, reducing the number of severe cases worldwide.

Norovirus

Norovirus is the second most common viral cause of diarrhea in children. It is responsible for 17-30% of diarrhea cases in kids between 1 and 60 months old.

Norovirus causes mild symptoms and usually only lasts a short time, but it can lead to dehydration in some cases. Good hygiene, like washing hands frequently, is key to preventing norovirus.

Bacterial Causes of Acute Diarrhea

Bacterial infections are also a major cause of acute diarrhea, especially in areas with poor sanitation and hygiene. Some common bacterial infections include:

1. Salmonella spp.

Salmonella is a bacteria often found in undercooked poultry, eggs, and dairy products. It can cause symptoms like diarrhea, abdominal cramps, and fever.

In severe cases, it can lead to blood poisoning, which can be dangerous, especially for children and the elderly.

2. Shigella spp.

Shigella is responsible for a type of dysentery that causes bloody, mucus-filled diarrhea. It spreads through contaminated water or food and is highly contagious.

People with Shigella infection often need antibiotics to help treat the illness.

3. Campylobacter spp.

Campylobacter is another bacterial infection that often comes from eating undercooked poultry or drinking untreated water. It can cause diarrhea, fever, and stomach cramps, and in some cases, it can lead to more serious health problems.

4. Enteroinvasive E. coli (EIEC)

Enteroinvasive E. coli is a strain of E. coli bacteria that can cause bloody diarrhea. It spreads through contaminated food or water and is more common in areas with poor sanitation.

Like Shigella, it can be treated with antibiotics.

Parasitic Causes of Acute Diarrhea

Parasites are less common than viruses or bacteria, but they can still cause persistent diarrhea. The most common parasitic infections in Indonesia are:

Giardia lamblia

Giardia is a parasite that causes a condition known as giardiasis, leading to diarrhea, bloating, and stomach cramps. It is often spread through contaminated water, especially in rural areas.

Giardiasis can last for weeks if not treated properly, so it is important to seek medical care if symptoms persist.

Entamoeba histolytica

This parasite causes amoebiasis, which leads to diarrhea and sometimes bloody stools. It is typically spread through contaminated water or food.

In severe cases, amoebiasis can cause liver abscesses, so it is important to get treated if you suspect you have this infection.

Risk Factors for Acute Diarrhea

Certain factors make people more likely to get acute diarrhea. These include:

• Poor hand hygiene: Not washing your hands after using the toilet or before eating can increase your risk of infection.
• Dirty water: Drinking or using untreated water for food or hygiene can expose you to viruses, bacteria, and parasites.
• Improper food storage: Keeping food in warm or open environments can allow bacteria to grow, increasing the chance of foodborne illness.
• Eating spoiled food: Consuming food that has been sitting out for too long can lead to food poisoning, which causes diarrhea.

Children under the age of two and males are more likely to get diarrhea, especially in places where sanitation controls are weak.

Preventing Acute Diarrhea

You can lower your risk of getting acute diarrhea by following some simple hygiene and safety tips:

1. Wash your hands regularly: Wash your hands with soap and clean water, especially after using the bathroom and before eating.
2. Drink safe water: Always drink treated or boiled water and avoid consuming ice made from untreated water.
3. Store food properly: Keep food at the right temperature and make sure it is fully cooked before eating.
4. Get vaccinated: Vaccination can help protect children against rotavirus, one of the leading causes of severe diarrhea.

Frequently Asked Questions

What causes sudden diarrhea?

Sudden diarrhea is usually caused by viral or bacterial infections like rotavirus or E. coli, often spread through contaminated food or water, which is common in tropical areas. It can also result from food intolerances, certain medications, or traveler’s exposure, with symptoms appearing within hours.

Can food poisoning cause acute diarrhea?

Yes, food poisoning can lead to acute diarrhea. Bacteria like Salmonella or Staphylococcus, found in undercooked or spoiled food, release toxins that cause diarrhea, cramps, and vomiting.

In Indonesia, risks from street food hygiene are common causes of foodborne illnesses.

How do infections trigger diarrhea?

Infections trigger diarrhea when viruses or bacteria damage the gut lining or release toxins that disrupt the body’s ability to absorb fluids. For example, viruses like norovirus inflame the intestines, and bacteria like Shigella cause immune reactions that speed up digestion and increase bowel movements.

Can stress cause diarrhea?

Yes, stress can cause diarrhea. Anxiety and stress can activate the gut-brain connection, speeding up digestion and affecting water balance in the intestines.

This “stress diarrhea” is common during stressful times and can worsen if you are already at risk of infections in busy environments.
