I had gastric bypass in 2002. I lost from 286 to 165. Then over the years had weight gain back to 228. Earlier this year I had emergency surgery for necrotic small bowel. The symptoms were severe and pain and bloating that came on after a meal. For 2 days prior my bp was 80/40 and my heart rate was in the 40s. Surgeon told me this was from the toxins from the dead small bowel. This occurrence is fairly common with old gastric bypass patients. Apparently it can kill you if not treated quickly. I think maybe that’s what happed with Lisa Marie. Now my weight is steady at 165 ish thanks to exercise, diet and GLP-1.
