Attachment DeletedPreventing diabetes complications
As indicated above, diabetes can affect many parts of the body and can lead to serious complications such as blindness, kidney damage, and lower-limb amputations. Working together, people with diabetes, their support network, and their health care providers can reduce the occurrence of these and other diabetes complications by controlling the levels of blood glucose, blood pressure, and blood lipids, and by receiving other preventive care practices in a timely manner.
Glucose control
•Studies in the United States and abroad have found that improved glycemic control benefits people with either type 1 or type 2 diabetes. In general, every percentage point drop in A1c blood test results (e.g., from 8.0% to 7.0%) can reduce the risk of microvascular complications (eye, kidney, and nerve diseases) by 40%. The absolute difference in risk may vary for certain subgroups of people.
•In patients with type 1 diabetes, intensive insulin therapy has long-term beneficial effects on the risk of cardiovascular disease.
Blood pressure control
•Blood pressure control reduces the risk of cardiovascular disease (heart disease or stroke) among people with diabetes by 33% to 50%, and the risk of microvascular complications (eye, kidney, and nerve diseases) by approximately 33%.
•In general, for every 10 mmHg reduction in systolic blood pressure, the risk for any complication related to diabetes is reduced by 12%.
•No benefit of reducing systolic blood pressure below 140 mmHg has been demonstrated in randomized clinical trials.
•Reducing diastolic blood pressure from 90 mmHg to 80 mmHg in people with diabetes reduces the risk of major cardiovascular events by 50%.
Control of blood lipids
•Improved control of LDL cholesterol can reduce cardiovascular complications by 20% to 50%.
Preventive care practices for eyes, feet, and kidneys
•Detecting and treating diabetic eye disease with laser therapy can reduce the development of severe vision loss by an estimated 50% to 60%.
•About 65% of adults with diabetes and poor vision can be helped by appropriate eyeglasses.
•Comprehensive foot care programs, i.e., that include risk assessment, foot-care education and preventive therapy, treatment of foot problems, and referral to specialists, can reduce amputation rates by 45% to 85%.
•Detecting and treating early diabetic kidney disease by lowering blood pressure can reduce the decline in kidney function by 30% to 70%. Treatment with particular medications for hypertension called angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) is more effective in reducing the decline in kidney function than is treatment with other blood pressure lowering drugs.
•In addition to lowering blood pressure, ARBs and ACEIs reduce proteinuria, a risk factor for developing kidney disease, by about 35%.
