Learn about diarrhea

Diarrhea occurs when your stools are loose and watery and can be caused by a variety of factors. If you have diarrhea, you may also feel the urge to have bowel movements multiple times a day.

Diarrhea can be acute or chronic. While acute diarrhea lasts 1–2 days, chronic diarrhea can persist for several weeks. When diarrhea symptoms persist, it usually indicates other health problems, such as irritable bowel syndrome (IBS), or a more serious disorder like irritable bowel disease (IBD).

 

Diarrhea causes

Diarrhea can occur as a symptom of several conditions or circumstances. Some potential causes of diarrhea include:

 

  • Viral infections, including rotavirus and viral gastroenteritis (stomach flu)

  • Bacterial infections, including Salmonella and E. coli infection

  • Parasitic infections, including Cryptosporidium enteritis

  • Digestive tract problems, such as irritable bowel syndrome (IBS)

  • Food sensitivities and allergies

  • Adverse reactions to medications

  • Taking antibiotics (antibiotic-associated diarrhea)

  • Gallbladder or stomach surgery


Rotavirus is the most common cause of acute diarrhea worldwide. In the United States, most people develop diarrhea due to food poisoning from eating contaminated foods, according to the CDC.

Diarrhea symptoms

The characteristic symptom of diarrhea is frequent, loose, and watery stools. Diarrhea may also cause frequent urges to have a bowel movement.

The symptoms of diarrhea vary from person to person, and a person's symptoms will depend on the specific cause of their diarrhea. Common diarrhea symptoms include:

 

  • Nausea or upset stomach

  • Abdominal pain

  • Cramping

  • Bloating

  • Lost fluids (dehydration)

  • A frequent urge to have a bowel movement

  • A large volume of stools


When the body loses water due to frequent bowel movements, you may experience dehydration. Dehydration can be a serious side effect of diarrhea. Symptoms include:

 

  • Feeling thirsty

  • Having a dry mouth and nostrils

  • Fatigue and lightheadedness

  • Fast heart rate

  • Not urinating as often

  • Sunken soft spot on a baby's head

How to treat diarrhea

Treatment for diarrhea depends on its cause. If your diarrhea doesn't go away in a few days, talk to your doctor to determine the underlying cause of your diarrhea and start an appropriate treatment plan.

 

Treating diarrhea usually involves:

 

  • Rehydration therapy: In most cases, treating diarrhea involves rehydrating. In other words, you'll need to drink bottled water or electrolyte drinks to replace lost fluids. If you have severe dehydration, you may get fluids through intravenous (IV) therapy.

  • Over-the-counter medication: If you have mild acute diarrhea, over-the-counter medications can help. For example, loperamide (Imodium) or bismuth subsalicylate (Pepto-Bismol or Kaopectate) can help ease symptoms.

  • Home treatments: Make sure to drink plenty of water and other electrolyte-balanced fluids, such as broths, fruit juices, and sports drinks. Instead of consuming fatty or fried foods, follow a bland diet (such as the BRAT diet) until your symptoms improve to avoid making diarrhea worse.

  • Prescription medication: If your diarrhea is caused by a viral, parasitic, or bacterial infection, your doctor may prescribe antibiotics or other medications.

Diarrhea medications

Most cases of acute diarrhea can be treated at home with over-the-counter medications, such as loperamide (Imodium) or bismuth subsalicylate (Pepto-Bismol or Kaopectate).

If your symptoms don't improve in a few days with OTC treatment, talk to your doctor. If your diarrhea is caused by a bacterial or parasitic infection, you'll need to see your healthcare provider for treatment.

Depending on the cause of your diarrhea, your doctor may prescribe:

Prescription loperamide (Imodium)

This anti-motility agent works to slow down your diarrhea frequency

Antibiotics

If you have a bacterial infection or parasite, your healthcare provider may prescribe antibiotics to combat the infection. Signs of bacterial infections include fever with bloody diarrhea. Parasitic infections usually include chronic diarrhea and weight loss and need to be evaluated with stool tests to ensure accurate diagnosis.

Medications for specific conditions

Chronic diarrhea may be related to other health conditions, including Crohn's disease, irritable bowel syndrome (IBS), and intestinal tract problems. Once your doctor reviews your medical history, they can prescribe medication to manage and prevent diarrhea.

Probiotics

Probiotic supplements can help re-establish the balance of "good" and "bad" bacteria in your gut biome. Always talk to your doctor before starting probiotics or other supplements.

How to prevent diarrhea

Diarrhea can happen for several reasons, and it's not always possible to prevent it. However, you can lower your risk of developing diarrhea by taking preventive measures:

 

  • Wash your cooking and food preparation areas frequently.

  • Serve food immediately after preparing it.

  • Always thaw frozen food in the refrigerator.

  • Refrigerate leftovers promptly.

 

When you're traveling, make sure everything you eat and drink is safe to avoid traveler's diarrhea, especially if you travel to developing countries. Travel safety tips include:

 

  • Avoid drinking tap water or using it to brush your teeth.

  • Don't drink milk that hasn't been pasteurized.

  • Avoid eating raw fruits unless you wash and peel them.

  • Make sure meat and shellfish are hot when served.

  • Avoid eating foods from food trucks and street vendors.

When to see a doctor for diarrhea

Most cases of acute diarrhea improve within a few days. However, if your diarrhea symptoms persist for longer than two days, you should seek medical attention. Persistent diarrhea can significantly increase your risk of dehydration.

Diarrhea can also be a symptom of serious medical conditions. Seek medical attention if you experience diarrhea with any of the following symptoms:

 

  • Frequent vomiting

  • Bloody stools, or stools that look black or tarry

  • Six or more loose stools in 24 hours

  • Severe abdominal or rectal pain

  • Dehydration symptoms

  • Fever of 102 °F (38.9 °C) or higher

 

Diarrhea treatment FAQs

What are the symptoms of diarrhea?

The most common symptom of diarrhea is watery, loose stool. If you have diarrhea, you may also experience a frequent urge to empty your bowels.

The symptoms of diarrhea vary depending on the specific cause of diarrhea. Some common symptoms include:

  • A frequent urge to use the bathroom

  • Loss of body fluids (dehydration)

  • Abdominal pain or cramps

  • Nausea (upset stomach)

  • Swelling or bloating

  • Feeling unable to control your bowels (incontinence)

 

Persistent diarrhea can also cause dehydration, which can turn into a serious medical condition. Dehydration is especially dangerous in children, older adults, and people with weakened immune systems.

How long is too long for diarrhea?

If you experience diarrhea for more than two days, seek medical attention. While most cases of acute diarrhea improve within a few days, persistent symptoms can lead to dehydration. If left untreated, dehydration can be life-threatening.

If your diarrhea gets worse or symptoms don't improve with over-the-counter medications, talk to your doctor. Chronic diarrhea can be a symptom of a medical condition, such as IBS.

If your diarrhea is caused by a parasitic or bacterial infection, you'll need stool testing followed prescription medication to treat the infection. A PlushCare doctor may be able to provide you with these prescriptions when necessary, but may also need to help guide you toward in-person or specialist care with referrals and resources.

Seek immediate medical attention if you experience diarrhea with:

  • Severe abdominal or rectal pain

  • A fever higher than 102 °F (38.9 °C)

  • Bloody stool, or stool that appears black and tarry

  • Severe dehydration symptoms including fainting

  • Six or more loose stools in the last 24 hours

Why do I have diarrhea?

In the United States, a common cause of diarrhea is food poisoning from eating contaminated foods. You can get food poisoning from eating:

  • Fresh, raw produce that hasn't been washed

  • Raw or undercooked meat, poultry, and eggs

  • Unpasteurized dairy products and fruit juices

  • Processed and ready-to-eat meals, such as hot dogs

  • Foods that aren't properly handled during preparation


There are several other potential causes of diarrhea, including:

  • Dietary intolerances or sensitivities to certain foods (i.e., lactose intolerance or celiac disease)

  • Eating foods that upset your stomach, such as fried or fatty foods

  • Viral infections, including rotavirus and viral gastroenteritis (stomach flu)

  • Bacterial infections, including Salmonella and E. coli infection
