Clear liquid diet: What you need to know

A clear liquid diet requires very little energy for the body to digest. Doctors may prescribe this diet in preparation for certain surgeries and medical procedures, or as a temporary remedy for gastrointestinal distress.

Some alternative health advocates also recommend a clear liquid diet when fasting or to detox the body.

In this article, we look at why a clear liquid diet is used, as well as the risks and benefits.

Clear liquids are easier for the body to digest. This means they leave nothing behind in the digestive tract, making it easier for doctors to perform a range of procedures.

Because clear liquids provide calories, electrolytes, and water, they help nourish the body and prevent dehydration. Clear liquid diets are safe for short-term use under the guidance of a doctor.

A clear liquid diet will vary depending on why a doctor has recommended it, so it is important for users to get a clear list of what is and is not allowed.

Liquids with red or purple coloring may also need to be avoided because they leave coloring in the intestinal tract that can look like blood. This makes it harder for doctors to get an accurate result with intestinal screening tests.

A person should not eat any solid foods, even fruits and vegetables, on a clear liquid diet.

A clear liquid diet can ensure that there is nothing left behind in the intestines before a medical procedure. This makes it easier to diagnose a variety of medical conditions.

Doctors may recommend a clear liquid diet before a colonoscopy, which is a procedure where a doctor examines the inside of the bowels. Certain other medical procedures may also require several days on a clear liquid diet, such as surgery on the intestines.

In most cases, it will also be necessary to fast immediately before surgery.

Recovering from a medical procedure

Some medical procedures can affect the ability of the body to digest and absorb food. A clear liquid diet allows the body to slowly recover, reducing the risk of nausea and making it easier to absorb nutrients.

Following bariatric surgery, for example, doctors typically recommend consuming only clear liquids to begin with. Over time, it will be safe to add other foods to the diet under the guidance of a doctor.

Preventing gastrointestinal distress

A clear liquid diet can be helpful after a period of nausea, vomiting, or diarrhea. Clear liquids are easier to digest and can reduce the severity of some stomach viruses. Switching to a clear liquid diet may also prevent dehydration.

People who are vulnerable to nausea due to chemotherapy, certain medications, or other medical conditions may benefit from trying a clear liquid diet at certain times.

For instance, in the days following chemotherapy, a doctor might recommend a clear liquid diet, particularly to a person who has a history of intense nausea.
