Why am I gaining weight on Lantus?
All Type 1’s and any Type 2’s on insulin should really be seeing an endocrinologist if possible. They specialize in glands and hormones, and insulin is a hormone. It’s true that insulin and the subsequent tightening of blood glucose control do cause us to gain weight. I gained 10 lbs. when I first went on a pump, but then I did Weight Watchers and took it back off. Try to keep your carbs moderate. 70 units of Lantus? That’s an awful lot…I used to take only 30 units a day and I’m Type 1. I’m concerned you’re going low a lot which would also contribute to the weight gain. Check with the endo about it and have them do some more monitoring with you.
