I was at the doctors yesterday, and one of the symptoms I have is a pretty big weight gain (my BMI is still only 21, but I've gained 13lbs ). The doctor asked if I'd been very hungry lately, and said that the main cause of weight gain in type 1 diabetics was excessive hunger because "insulin makes you hungry". Well, I know it makes you hungry if you take too much or go low or have sudden drops, but I didn't think that insulin in and of itself made us hungry. I mean, everyone has insulin in them, whether it's synthetic or produced by their pancreas.. Why would injected insulin make us hungrier, providing control is good? Just wondering if anyone knows if this is true, or why. As it happens I'm eating about half of what I used to and barely have any appetite, so this doesn't really apply to me anyway, but I was curious..
