Hello, I had a gastric bypass over 30yrs ago and getting ready for a gastric bypass revison..But if you take omega3 and get your Protein you won't be losing your hair or be mal-nurished..This is a chance for you to have a great life..You will cry and you will want the things you ate before, but that want will go away, I found keeping busy helped me..As the years passed and I started gaining weight the last 10yrs I finally went to a Dr. and found out that the way they did the surgery 30yrs ago has had a big change so I'm just getting started and hoping I will be able to get my surgery..I wish you luck....I'm going to Dr Fang...
