A clear liquid diet is prescribed by a doctor before certain medical procedures and tests are performed, after some types of surgery, and sometimes to treat nausea, vomiting or diarrhea. The only solid foods included on a clear liquid diet are those that become liquid at room temperature, such as some frozen snacks and gelatin desserts. The amount of time spent on a clear liquid diet varies, depending on the conditions under which it is prescribed.
Features
The beverages that are allowed on a clear liquid diet include water, club soda, seltzer, chicken broth, beef broth, vegetable broth, bouillon, strained juice with no pulp, such as grape juice, cranberry juice and apple juice, strained lemonade, sports drinks, powder-based beverages, black coffee, tea and sodas such as lemon-lime flavored and ginger ale. Plain gelatin desserts, honey, maple syrup, jellies, frozen ice pops and hard candies are also allowed. No solid food and no milk or other dairy or non-dairy creamers are allowed.
Function
A clear liquid diet clears the bowel, and because it requires very little digestion, gives the entire gastrointestinal tract a rest. At the same time, the diet provides fluids and electrolytes, or minerals, to prevent dehydration. A clear liquid diet is used whenever a clean bowel is necessary to perform a medical examination such as a colonoscopy or whenever the gastrointestinal tract must be completely empty to perform a medical procedure such as colorectal surgery. This diet is also used to help the gastrointestinal tract recover from an illness or medical procedure.
Identification
A clear liquid diet is not to be confused with a full liquid diet, which allows some soft foods such as hot cereals and strained soups. Alcohol is not included on a clear liquid diet and a doctor may restrict caffeine to prevent dehydration or stomach upset.
Time Frame
A clear liquid diet may be prescribed for as little as a few hours or as long as several days. For medical tests and procedures, a clear liquid diet may be prescribed for 24 hours prior to the procedures. A clear liquid diet prescribed after surgery may be followed by full liquid diet and then gradually include bland and easily digestible solid foods, such as cream of wheat and farina cereals. As each diet is tolerated, more foods are added.
Warning
A clear liquid diet is usually followed under a doctor's orders. Since this diet does not provide enough calories, nutrients and energy for normal living, it should be followed for no more than a few days.
