I weight 160, 5'6 in height, type 2 diabetes, take onglyza (saxagliptin) 2.5 & metformin 500mg, 6.5 in a1c. do i need to lose weight?

Doctor can examine: A type 2 diabetic at 160 pounds can ask his doctor if he should lose some weight. The doctor will base the decision on factors such as: how heavy was the patient to begin with, how fast and how much weight did he already lose, is he having any complications from rapid weight loss, etc... If there are no reasons why he shouldn't lose more weight, then it is fine to lose some more.

Not necessarily: Are you happy with your weight now? Normal bmi is 18.5-24.9. Your bmi is 25.8 which is just slightly above normal. Being at a healthy weight has lots of health benefits. At this point trying to focus on a healthy life style, being active, healthy eating (increase veggies, fruits, low fat foods), watch portion sizes and work on keeping blood sugar controlled would be helpful. Good luck.

Yes: At your height and weight your bmi (body mass index) is 26. You would like to get your bmi closer to 20. Trying to lose 20 or 30 pounds would be ideal, but even a 10 pound weight loss would help.
