Allergy drugs cure for diabetes?

Over-the-counter allergy and asthma drugs can help obese, diabetic mice lose weight and control their blood sugar, researchers report.

Three other studies strongly linked obesity and type-2 diabetes to a dysfunctional immune system, and researchers say these findings could lead to better drugs or perhaps even vaccines to treat the effects of both conditions.

Rates of obesity and type 2 diabetes are surging around the world as people eat more and exercise less. The four studies published in the journal Nature Medicine help explain how obesity might cause diabetes and how the two together can cause organ damage, heart disease and death.
