When to Consult with a Gastroenterologist in Dubai?

There are seven telltale signs that your body gives, indicating that it is time to visit your closest gastroenterologist:

  • Ongoing diarrhoea: If you have frequent loose stools that show no sign of improvement.+
  • Constipation: You have clinical constipation if your bowel movement is fewer than thrice a week.
  • Frequent severe heartburn: Frequent heartburn can indicate the presence of GERD, which requires professional treatment.
  • Constant feeling of bloating: If you feel bloated most of the time, it may indicate gas entrapment or other GI issues.
  • Sudden, severe pain in the abdomen: abdominal pain that has rapid onset and lasts for hours isn’t normal – it can be a sign of gallstones, liver disease, etc.
  • Blood in the stool or bleeding from the rectum: Seeing blood on your toilet paper indicates several problems with the GI tract/vomiting blood
  • Scheduled colonoscopy and endoscopy: If you are a senior, you may have a routine colonoscopy scheduled – visit your gastroenterologist to rule out the presence of any disorders.

Procedures and Treatments Offered Across Dubai, Sharjah, and Abu Dhabi

The gastroenterology department at Aster Clinics is equipped with cutting-edge technologies that help doctors screen, test, diagnose, and treat a wide range of GI problems. Some procedures offered across our clinics in the UAE are:

A screening procedure where a long, flexible colonoscope is inserted into the large intestine (colon) to screen for problems affecting this region.

Upper GI Endoscopy
A procedure where a long, thin tube (endoscope) is inserted into your upper GI tract to see if there are any blockages, strictures, or indications of Gastroesophageal Reflux Disease (GERD). To glean more information from this procedure, you may need to subsequently undergo procedures like:

  • Biopsy
  • Dilation of constricted areas
  • Foreign object removal
  • Surgical treatment, if needed

Capsule Endoscopy
This procedure is generally to study the small bowel disease

Endoscopic Ultrasound
This procedure is generally performed when the signs and symptoms point towards the presence of stones in the biliary ducts, tumours or cancer. The instrument used consists of an ultrasound device attached to an endoscope.

ERCP stands for Endoscopic Retrograde Cholangiopancreatography. The procedure involves using an endoscope guided by an X-ray to diagnose problems in the pancreatic ducts, bile ducts, etc. If there are gallstones or blockages, they may also be removed during the same procedure.

This procedure is similar to endoscopy and is performed in the lower part of your colon and the rectum. It is used to diagnose severe conditions of the GI tract, like colon and rectal cancers.

Polyps are non-cancerous growths that create problems in the GI tract. Polypectomy is the procedure doctors use to remove these polyps using tools like loop forceps or electric current during colonoscopy.

Oesophageal Dilation
If you find it hard to swallow food, you may have constrictions in your esophageal area. The procedure entails dilating this constriction using plastic dilators or inflating a balloon.

Urea Breath test to detect H pylori bacteria in the stomach

Hydrogen Breath test to rule the bacterial overgrowth in intestine
