Type 1: Does Lantus cause weight gain?

Over the past couple of months my long honeymoon period seems to be slowly disappearing and I've been gradually increasing my Lantus dose to retain the same fasting levels.

I am eating the same diet as always and exercising the same amount (if not more) than I did previously. My control remains tight. Nothing has changed except my Lantus dose. I am convinced the increased Lantus is causing weight gain: I have gained 5kg in the last couple of months and my waist has also gained a couple of inches.

Are there any studies on Lantus causing weight gain?
 
Insulin is known to cause weight gain but there could be other reasons for example - hypoactive thyroid. (I went on to Lantus over a year ago and I am lucky I haven't put on weight with it.)
 
Thanks. Looks like there are a few studies showing Levemir is less likely to lead to weight gain than Lantus. Maybe I'll speak to my team about switching.

That's not wholly correct. The OP is a Type 1. Excessive food/carbs requiring more insulin may cause weight gain but it's wrong to say insulin per se makes you gain weight. I've been taking it for more than 20 years and my weight has stayed stable and I remain slim.

@pinewood I think @mahola said something about Lantus and weight. Perhaps she can help?
