Think skinny people don’t get type 2 diabetes? Think again.
In the last article we discussed the complex relationship between body weight and type 2 diabetes (T2DM). We learned that although obesity is strongly associated with T2DM, a subset of “metabolically healthy obese” (MHO) people have normal blood sugar and insulin sensitivity and don’t ever develop diabetes.
In this article we’re going to talk about the mirror reflection of the MHO: the “metabolically unhealthy nonobese” (MUN). These are lean people with either full-fledged type 2 diabetes or some metabolic dysfunction, such as insulin resistance.
You might even be surprised to learn that skinny people can and do get T2DM. They are rarely mentioned in the media, and there isn’t much written about them in the scientific literature. Perhaps these folks have been overlooked because type 2 diabetes has been historically viewed as a disease of gluttony and sloth, a self-inflicted outcome of eating too much and not and not exercising enough. But the very existence of the MUN phenotype proves that there’s more to T2DM than overeating and a sedentary lifestyle.
Remember that one in three type 2 diabetics are undiagnosed. It’s possible that a significant number of these people that are lean. They don’t suspect they might have T2DM because they’re under the impression that it’s not a condition that affects thin people. This is one of the biggest dangers of the myth that “only fat people get diabetes”.
It’s well-known that high blood sugar can precede the development of T2DM for as long as ten years. It is during this time that many of the complications as Continue reading
