I asked the surgeon about my weight loss and not getting the nutrients because of the blocked pancreatic duct. He said to drink 3 protein shakes a day like the Boost shakes I drink about 5-6 a week. So, I did that, and I do feel a lot better and stronger. Thing is there is a lot of vitamin K in them, and it took over an extra week to get my INR in range and stop the large painful Enoxaparin shots I have to take when stopping and restarting my blood thinners. I had to cut the shakes back to 2 a day and even missed a day to get my INR back to the 2-3 range. I was stuck at 1.5. I am feeling like doing some work around the house now. After surgery I will try to do the 2 shakes a day to help with healing.
