Insulin Therapy For Type 2 Diabetes 'may Do More Harm Than Good'
A new study published in the journal JAMA Internal Medicine suggests that for older patients with type 2 diabetes, medications to lower blood sugar levels may "do more harm than good." Approximately 25.8 million people in the US have diabetes, with type 2 diabetes accounting for 90-95% of all cases. Type 2 diabetes is characterized by insulin resistance - the inability of the body to produce enough insulin or use the hormone effectively, which causes high blood sugar levels. Over time, high blood sugar levels can cause kidney, eye or heart diseases, nerve damage or stroke. Diagnosis of type 2 diabetes is usually determined through a blood test that measures hemoglobin A1c levels in the blood. This test reveals the average level of glucose the patient has had in their blood over the past 3 months. In the US, type 2 diabetes is diagnosed when hemoglobin A1c levels reach 6.5% or higher. The higher A1c levels are, the greater the risk of other health problems. Sometimes the condition can be managed through changes in diet, but other patients with type 2 diabetes may need medication - such as insulin or metformin - to help lower their blood sugar levels, and ultimately, reduce the risk Continue reading >>
