Preparation for Bariatric Surgery

Careful preparation is the key to success. Here you will learn what you need to know and do before a sleeve gastrectomy or gastric bypass operation.

Medical Preliminary Examinations

Blood tests (complete blood count, liver, kidney, hormones)
EKG and cardiac examination
Gastroscopy (endoscopy)
Sleep lab if sleep apnea is suspected
Psychological evaluation
Nutritional counseling

Diet Before Surgery

Often 2–4 weeks before surgery, a liver-shrinking diet is recommended (high protein, low carbohydrate). A smaller liver facilitates access to the stomach and reduces surgical risks.

Quit smoking (at least 4 weeks before surgery)
Avoid alcohol completely
Regular light exercise
Adequate sleep

What You Should Bring

All current medication lists
Previous findings and doctor’s letters
List of your allergies
Companions for support
