Diarrhea means loose stools, liquid stools. It may be mild or severe, with the duration running from days to weeks. It all depends on the cause.

Apart from the watery bowel movements, other symptoms may include:

  • The urgency to visit the loo
  • Frequent passing of stools (no less than three times per day)
  • Abdominal cramps
  • Abdominal pain
  • Nausea
  • Inability to control bowel movements

The patient may also experience dizziness, fever, or vomiting. These symptoms manifest when the condition is caused by an infection.

If your stools are watery, you may be wondering how long diarrhea will last. Let us examine the typical duration of diarrhea, together with its home remedies, and symptoms that indicate you should see your doctor.

How long does diarrhea last?

There are two types – acute and chronic.

Acute diarrhea is short-term. It lasts for a day or two. In some cases, it may last up to two weeks. Acute diarrhea is usually mild and often resolves on its own.

Chronic diarrhea lasts for at least a month. The symptoms fluctuate, but it could indicate a serious condition.

Causes of diarrhea

Several factors may contribute to the onset of diarrhea. The symptoms, as well as the duration, depends on the cause.

Acute diarrhea may be due to:

  • Stomach flu
  • Bacterial infection
  • Food allergy
  • Allergy to medications (like antibiotics)
  • Stomach surgery
  • Food intolerance, such as lactose or fructose intolerance
  • Traveler’s diarrhea, usually caused by bacteria

Norovirus is the commonest cause of acute diarrhea in adults.

Common causes of chronic diarrhea include:

  • An inflammatory bowel disease, like Crohn’s disease or ulcerative colitis
  • Parasitic infection
  • Celiac disease
  • Irritable bowel syndrome
  • Gallbladder removal
  • Medications for heartburn (such as protein pump inhibitors)

Diarrhea before a colonoscopy

You may also experience this condition while preparing for a colonoscopy. Because colonoscopy involves emptying your colon, you’ll have to take a strong laxative beforehand to flush every stool out of your colon. You’ll receive a prescription laxative so you can start taking a day before your colonoscopy.

The kind of laxative prescribed by your doctor is so designed to trigger diarrhea without draining your body fluids. With this, you’re safe from dehydration.

After taking the laxative, you will experience a few hours of forceful diarrhea as your colon evacuates the stool from your colon. You may also experience nausea, abdominal cramps, or bloating.

You will be relieved of your condition shortly before you’re due for the colonoscopy. Gassing and abdominal discomfort is common after a colonoscopy, with your bowel movements returning to normal within 24-48 hours.

If you are worried about diarrhea while prepping for a colonoscopy, consult your doctor on how to ease the process.
