DiabetesScreening

Diabetes screening is the process of identifying individuals who may have diabetes or prediabetes before they exhibit symptoms. Early detection is crucial as it allows for timely intervention and management, which can prevent or delay serious complications associated with diabetes, such as heart disease, kidney disease, nerve damage, and vision loss.

Various screening methods are employed. The most common involves blood tests that measure glucose levels. These include the fasting plasma glucose (FPG) test, which measures blood sugar after an overnight fast; the oral glucose tolerance test (OGTT), which measures blood sugar before and after drinking a sugary liquid; and the hemoglobin A1c (HbA1c) test, which provides an average of blood sugar levels over the past two to three months.

Recommendations for who should be screened and how often vary depending on age, risk factors, and guidelines from health organizations. Generally, adults aged 45 and older are advised to be screened regularly. Individuals younger than 45 who are overweight or obese and have one or more risk factors, such as a family history of diabetes, a history of gestational diabetes, or certain ethnic backgrounds, may also benefit from screening. Risk factors also include physical inactivity, high blood pressure, abnormal cholesterol levels, and polycystic ovary syndrome.

The results of screening tests help healthcare providers determine if a person has diabetes, prediabetes, or normal blood glucose levels. Prediabetes indicates that blood sugar levels are higher than normal but not yet high enough to be diagnosed as type 2 diabetes. Lifestyle modifications, such as diet and exercise, can often reverse prediabetes or slow its progression to type 2 diabetes. If diabetes is diagnosed, a comprehensive management plan is developed, which may include lifestyle changes, medication, and regular monitoring.
