When Should You Visit A Specialist For Diarrhoea?

In most cases, acute diarrhoea is fleeting and will resolve by itself within a few days. However, persistent and chronic diarrhoea may signal an underlying medical condition. If left untreated, it could result in more severe complications.

Consult a Gastroenterologist if you experience any of the following:

  • Fever
  • Bloody stools
  • Vomiting
  • Dehydration (dark urine, decreased frequency of urination, inability to increase fluid intake or light-headedness)
  • Abdominal pain

Persistent diarrhoea can lead to severe dehydration, which can be dangerous, especially for infants and young children, the elderly, and those with specific chronic medical conditions or a weakened immune system.

Make an Enquiry

If you are experiencing abnormal diarrhoea or severe dehydration, you should see a specialist or seek immediate medical help.

What Causes Diarrhoea?

Acute diarrhoea is typically caused by viral or bacterial infections, while chronic diarrhoea may occur due to other chronic medical conditions.

Here are some causes of diarrhoea:

  • Food poisoning due to bacterial infection (Salmonella and E. Coli) from contamination of food or drinks
  • Gastroenteritis (stomach flu)
  • Parasitic infections
  • Food intolerance such as lactose intolerance
  • Anxiety or stress
  • Side effects of certain medications
  • Irritable bowel syndrome (IBS)
  • Inflammatory bowel disease (IBD)
  • Cancer

Schedule An Appointment With Our Clinic

Diarrhoea may signal an underlying medical condition. Schedule an appointment with a qualified gastroenterologist to find out the cause of your symptoms.

How Is Diarrhoea evaluated?

  • Review of medical history and dietary habits
  • Physical examination
  • Blood, urine or stool sample tests
  • Imaging tests such as x-rays and CT scans may be used to detect any abnormalities or inflammation in the abdomen
  • Colonoscopy (to examine the entire colon)
  • Sigmoidoscopy (to examine the lower part of the colon and rectum)

How Is Diarrhoea Treated?

Over-the-counter medications

  • Antidiarrheal medications can slow down bowel movements and make stools more solid
  • Probiotics can restore the balance of bacteria in the intestinal tract

Home remedies

  • Drink plenty of water to prevent dehydration
  • Consuming oral rehydration drinks to replace lost minerals and salts from diarrhoea
  • Have adequate rest, particularly if diarrhoea is caused by stress or anxiety

Other treatment options

Definitive treatment for diarrhoea depends on the underlying cause eg if due to inflammatory bowel disease, that would require medication to suppress the overactive immune system.
