Hi I'm Lisa. I had a gastric bypass in '09. I suffered complications and had to have another surgery to correct 3 internal hernias from trocar sites not being closed during the original surgery with a peterson defect. I had drastic weight loss and malnutrition and malabsorbation with the first surgery by the time my second surgery was performed I had started having heart problems. Pain, fluttering in my chest. I had lost 150 pounds in 4 months and was very ill. I have had an intensive cardiac work up this past several months...Diagnosed so far, with Microvascular spasms and have been placed on dilitezem...Hope I'm spelling correctly. I am still having problems with my absorbation of vitamins. I am 5'4 and 240 now. My blood pressure stays around 85/60ish, with my heart rate in the high 40's to low 50's. I was wondering if the malnutrition has caused my microvascular spasms.
