A San Diego doctor is making headlines for creating a drink that's improving the quality of life for anyone who's about to have surgery.

Doctor Lou Marsh came up with an idea to produce a nutritious drink that would solve the problem of patients having to fast before surgery and experience dehydration and hunger.

Her business partner is a former patient of hers who told her he owns a beverage company just before going under the knife.

Together they created "Clearfast" and the product has been featured at medical conferences all over the country.
