There is a growing concern about diabetic retinopathy, where the rising prevalence of diabetes is linked to increasing cases of vision loss.

The South Indian states are no exception. Diabetic retinopathy, a severe complication of diabetes, could lead to irreversible blindness, if not detected and treated early.

Health

The age-standardised prevalence of diabetes in South India is approximately 12 percent, with an additional 14 percent of the population classified as prediabetic.

Health

Kerala: Known as the “diabetes capital” of India, the state reports a prevalence of around 20-25%.

Health

Tamil Nadu: Urban areas report diabetes rates as high as 20%. Telangana and Andhra Pradesh: Both states exhibit a 10-15% prevalence.

Health

Karnataka: Similar trends are observed, particularly in urban centers.

Health

Diabetic retinopathy occurs when high blood sugar levels damage retinal blood vessels, leading to vision impairment or blindness.
