How Long After Diabetes Diagnosis Do Complications Appear

“I was newly diagnosed with diabetes last year. After how long does this disease lead to serious complications?” — John, Florida.

Diabetes is a group of metabolic disorders related to elevated or reduced blood glucose levels. Aside from gestational diabetes in pregnant women, diabetes can be divided into two main types. Type 1 diabetes is an autoimmune form in which the immune system attacks and destroys the pancreatic beta cells (which produce insulin). Type 1 often occurs in children and adolescents, but can also appear in adults.

Type 2 diabetes is the more common form, accounting for 90–95% of diabetes cases, occurring when the body cannot use insulin efficiently or does not produce enough insulin. It typically develops in adults, especially those who are overweight or obese.

The disease causes blood-sugar metabolism disorders. If high blood sugar stays in the blood for too long and is not treated in time, many serious complications can result. The timeframe for complication onset depends on each individual’s disease control and treatment plan. If the disease is diagnosed late and blood sugar is not well controlled, complications can develop faster.

Some acute complications include low blood sugar (hypoglycemia), ketoacidosis, lactic acidosis, and hyperglycemia with increased osmotic pressure.

Chronic complications of diabetes tend to develop gradually, sometimes taking several years or even decades before becoming severe. Cardiovascular complications such as coronary artery disease, heart attack and stroke may develop over many years. The risk begins to increase after about 10 years from diagnosis.

Chronic kidney disease may occur after about 5–10 years of diabetes if blood sugar is not well controlled; early signs are not clear, but progression may lead to kidney failure, need for dialysis or transplant.

Retinopathy (eye damage) also commonly appears after about 5–10 years of having diabetes. If untreated, it may lead to blindness.

Nerve damage typically develops after 10–20 years, depending on how well blood sugar is managed. Symptoms include tingling, numbness and pain in the limbs; in severe cases this can result in ulcers and infections.

To reduce the risk of diabetic complications, you need to:

• Maintain stable blood sugar.

• Have regular check-ups of eyes, kidneys and other organs to detect early complications and treat promptly.

• Keep blood pressure and cholesterol within normal limits to help reduce cardiovascular risk.

• Quit smoking, maintain a healthy weight, reduce stress — all support stable blood sugar, blood pressure, and improved quality of life.

• Also you should undergo periodic screening for diabetes according to doctor’s advice. This helps early detection and prevention of chronic complications.
