By the year 2020, almost no patient will undergo anesthesia while starved and dehydrated

ClearFast PreOp is a clear, carb-rich drink, made for patients fasting before surgery or procedures such as colonoscopies.


The day of surgery can be extremely stressful, starving and dehydrating your body is no way to ease the mind before your procedure

Intense Hunger

Most patients experience intense hunger while in the fasting window before surgery

Increased Infection Risk

Starving before surgery means high blood sugars; add a surgical wound and you are especially prone to infection

Nausea & Vomiting

Patients often experience nausea, or vomit after surgery due to starvation & dehydration combined with anesthesia

Acids in the Stomach

Starving yourself actually does not empty your stomach…dangerous stomach acids collect in your stomach as a result of starvation and dehydration

Calm State

Patients who drink ClearFast before anesthesia can be less anxious and 5 times more comfortable

Nourished & Hydrated

ClearFast is a delicious carb rich beverage that hydrates with electrolytes and nourishes with just the right amount of calories to ease hunger

Reduced Infection Risk

Drinking ClearFast before surgery can stabilize blood sugars, greatly reducing the risk of infection after surgery (returning to the hospital)

Clear Stomach

When ClearFast is taken two hours before surgery, the stomach absorbs it along with potentially dangerous stomach acids.

Comfortable Recovery

Nausea and vomiting after anesthesia is greatly reduced when you hydrate and nourish beforehand.


Drinking ClearFast prior to your medical procedure is a safe way to speed up recovery time, nourish your body PreOp, and reduce PostOp nausea and vomiting. Research shows a patient entering surgery starved and dehydrated is the way of the past.
