What’s a Clear Liquid Diet?

A clear liquid diet is when your dietitian limits you to water and other meal-replacement drinks. It’s recommended chiefly before a medical procedure such as a colonoscopy or gastrointestinal surgery.

It’s necessary because you won’t undergo surgery if you don’t follow this diet. Since it’s a clear liquid diet, it won’t provide you with the calories and nutrients needed for your body. 

Even though the liquids from this diet will provide you with electrolytes and salt in the body to prevent dehydration, it is best not to follow it for more than five days.

However, if you have diabetes, talk to your health expert, who can help you manage your blood glucose level by providing some instructions. They may advise you to monitor your blood sugar levels off and on.

That said, the purpose of this diet is to keep your stomach free from any food particles before surgery. In addition, the consumption of liquids reduces bowel residue and, at the same time, kills your thirst.

Everyone knows well that you can’t eat food before surgery as it can create complications after anaesthesia.

The doctor wants your stomach to be empty before performing a medical procedure. In terms of chewing gum, it can raise the amount of fluid in your stomach. 

However, according to reports at the presented ANESTHESIOLOGY™ 2014 annual meeting, it’s safe to give anaesthesia to patients who fast and chew gum before surgery.

That said, chewing gum may increase the liquid volume in the stomach, but the stomach’s acidity remains unchanged. So it would not increase the risk of complications after anaesthesia.

In a study, the doctors chose 67 patients who had to undergo gastrointestinal surgery. Among them, 34 patients were to chew gum, while the remaining 33 were on a liquid diet.

The 34 patients had to chew gum right before the surgery, which they did. After that, following anaesthesia and endoscope insertion, they assessed the pH and acidity of the stomach.

The results showed high liquid in the stomach of 34 patients compared to those who did not. But, the pH value remained unchanged.

To sum up, it’s safe to chew gum before surgery, but it is better not to chew it 6 hours before surgery. It would be best to ask your doctor for further guidance.


What Happens If You Don’t Follow CLD Before a Surgery?

In many cases, it can cause death too. Mostly adults are not allowed to eat food for 6 hours and have liquids 2 hours before surgery.

Infants can have milk 4 hours before surgery, giving them only clear liquids afterwards.



A clear liquid diet is when you follow a diet which contains no solid foods. The liquids should be sugar and fat-free. People who have to undergo a medical procedure follow this diet.
