When following a clear liquid diet, you’ll need to monitor your blood glucose closely, and if you’re on medication, you’ll need to adjust it, according to StatPearls. While you may be used to drinking sugar-free soda and eating sugar-free gelatin, when following a clear liquid diet you need to include the regular versions of these foods to meet your daily carbohydrate needs, Hartford HealthCare in Connecticut says. They recommend eating about 15 grams of carbs per serving of clear liquid. In general, a half-cup serving of clear soda, juice, or gelatin contains 15 grams of carbohydrates, as do 1-cup servings of sports drinks, or one popsicle.
If you take medications, you’ll also need to make adjustments, according to the UMass Memorial Health–affiliated Diabetes Center of Excellence in Worcester, Massachusetts. Making sure your blood glucose levels are well-controlled is especially important before a surgery or procedure, to help reduce the risk of infection or other complications. How you’ll need to adjust your medications depends on the type of medication, how the medication is administered (pump, injection, or by mouth), and the length of time you’ll be on a clear liquid diet. You can usually return to your normal regimen once you’re cleared to eat normally again.
Your doctor will give you explicit instructions before you begin the clear liquid diet. Always reach out to them with any questions, and seek immediate medical attention for abnormal blood sugar readings or other complications.
