Increasing access to affordable insulin is among the objectives of the new Global Diabetes Compact, launched on Wednesday by the World Health Organization (WHO). The development comes as the risk of early death from diabetes is increasing, underscoring why countries must tackle the disease and bring treatment to all who need it, 100 years after the discovery of insulin. More than 420 million people worldwide live with diabetes, a group of chronic diseases characterized by elevated blood sugar, which can cause damage to the heart, blood vessels, eyes, kidneys, and nerves.  The most common is type 2 diabetes, which occurs when the body becomes resistant to insulin, the hormone that regulates blood sugar.
