The long term complications I've read about after gastric bypass and/or sleeve gastrectomy are nerve issues, dental problems (resulting in root canals, implants, dentures), reactive hypoglycemia, strictures, fibromyalgia, ulcers, fainting spells, chronic anemia, osteoporosis, etc. I don't know if MGB has the same issues as these other weight loss surgeries as there's a lot less info available online. One thought is the perception of risk could be skewed if more people that have issues post their experiences than people that don't have these issues. So I could be getting scared about possible outcomes that are very low risk. It's a conundrum I need to work through.
