Patient Information

Preoperative Guide

Bowel preparation

Purchase an 8-ounce bottle of magnesium citrate and use as directed. This preparation is a laxative and is intended to help empty your bowels.

Reaction to laxatives varies by person. Generally, bowel movements start 30 minutes after taking the prep; however, it may take as long as three hours. Because multiple bowel movements will occur, we recommend staying close to a restroom throughout the day.

Your meal plan

Fasting before surgery is important to your safety. It can keep your stomach empty enough on the day of your procedure to avoid certain complications, such as vomiting, while you are under anesthesia.

Notify your doctor before taking any aspirin or products that contain aspirin.


Your breakfast should be light and consist of small portions. Avoid saturated fats, trans fats and refined carbohydrates.

For example, eat one boiled egg and toast with no butter. Non-breakfast foods such as small portions of chicken, turkey or fish are also acceptable.

If you have questions about what you should or shouldn’t eat, please contact our office at 956-664-1616.

Lunch and dinner:

Drink only clear liquids for the rest of the day.

  • Water, Crystal Light, Propel, decaf tea
  • Fat free soups or low sodium chicken or beef broth/bouillon
  • Sugar free popsicles, sugar free Jell-O

PLEASE NOTE: Do not eat or drink after midnight.

If you fail to follow the diet guidelines above, there could be complications during surgery. If you have questions, please call the office at 956-664-1616.
