Malabsorbtion
Hi Phil, The doctor is absolutely right. There are huge responsibilities. I have taken my vitamins from the day I came home after surgery and have never stopped taken them. I had my blood work done regularly and it wasn't until 5 years post-op that these deficiencies arose. There is nothing I could have done to prevent it. From what I understand, this is a very common risk after 5 years from surgery.
Good luck to you with your surgery. Be healthy.
