Getting Constipation Despite A Regular Diet: A Gastroenterologist Explains

Constipation is such a common condition that to many people, it is a passing and temporary occurrence not to be worried about.

We know that diet is a major cause of constipation. By eating foods that aggravate the digestive system and compromise the digestion process, constipation is typically a symptom that follows.

However, many healthy eaters who pay attention to their daily diets have also experienced constipation.

A DoctorxDentist reader had constipation for two weeks in a row, despite taking a daily meal which includes green tea, low glycemic index bread, brown rice, and an assortment of fruits and vegetables to complement her lean food regimen.

Gastroenterologist Dr Quan Wai Leong discussed some possible causes of constipation people can have, even with a healthy diet. Here's what he had to share.

Ask Dr Quan Wai Leong: Endoscopy & Gallstones
Ask Dr Quan Wai Leong: Endoscopy & Gallstones

Endoscopy is a procedure where your doctor inserts a narrow flexible tube equipped with a camera through your mouth to examine your digestive tract. 

New advances in medical technologies allow endoscopists to do not only diagnostic procedures (identification and confirmation of disease situations) but also therapeutic (treatment of disease conditions such as removal of bile duct stones) endoscopies that would be minimally invasive and hence promote faster healing.

Join Dr Quan as he hosts a QnA session where he answers all your questions on endoscopy and gallstones.
