###Human: Is bariatric surgery advisable for the second time? ###Assistant: Hi. I went through your query and the reports (attachment removed to protect identity). Your testosterone level is normal. Though on the lower side of the normal range, there is nothing needs to be done to increase testosterone. There are medications to increase testosterone levels but it is not needed in your case. You can try some natural methods like doing aerobic exercise, eating more of citrus fruits, eating more of onion and garlic and also wear loose undergarments. While going through your reports, I noticed that your insulin levels and C-peptide levels are elevated. This suggests that you are having insulin resistance which may lead to diabetes in the future. So, kindly start doing aerobic exercise which will reduce insulin resistance.
