Question: Gastic Bypass & Gallbladder Romoval Nutrition

 PittsGuy - Wed Oct 28, 2009 2:24 pm

What kinds of supplements (vitamins, minerals, etc) should a woman be on who has had gastric bypass (roux-en-y) as well as a cholecystectomy? I have researched online to some avail for required supplements for each case, but I would like to know officially what combination should be taken for both. My girlfriend has misplaced all post-surgical information from her doctor, and we do not currently have medical insurance for an office visit and checkup. Thank you!

User avatar Hello,
Your gall bladder surgery recovery should not need any extra vitamins so your focus should be on the gastric bypass follow up care. Ideally you will be participating in some type of support group for patients who have experienced this life-changing surgery and this can help you find some good resources for supplements and recipes to help you maintain your weight loss. There are online resources as well such as and

Each weight loss patient has individual needs and labs should be drawn annually to monitor any low levels of B12, iron, etc. since these can be compromised with the procedure. Labwork should include at least CBC, iron, comprehensive metabolic profile, Intact parathyroid hormone, RBC folate, and B12.

All patients should take a good multivitamin daily and additional calcium (about 1000 mg daily, divided in two doses) is usually required. If your iron is low, this should be evaluated since it can be caused by a lack of intrinsic factor that allows iron to be absorbed by your body. You may need an iron supplement but perhaps vitamin B12 as well so your body can absorb it properly - daily in the sublingual form (under the tongue) or with monthly injections. B12 taken orally is not absorbed well. Also, taking iron with citrus fruits or juice will enhance absorption. Vitamin C helps this and some extra in a supplemental vitamin can't hurt. I would also recommend omega 3 supplements, like fish oil.

Follow your surgeon's advice for your specific needs and you should be able to get another copy of the post-op instructions just by contacting the office without needing an actual appointment. It is important to follow your doctor's eating plan and your doctor wants you to be successful and healthy.

Best wishes.
