Diabetes is becoming a growing public health concern in Sri Lanka, with nearly 15% of adults living with the condition, while approximately 40% of those affected are unaware that they have it, according to medical experts.

The concerning figures were highlighted on November 14, as Sri Lanka joined the world in observing World Diabetes Day.

Dr. Manilka Sumanatilleke, President of the Diabetes Association of Sri Lanka and Consultant Endocrinologist at the National Hospital of Sri Lanka, warned that diabetes has become an increasingly serious health issue in the country.

The situation is particularly concerning in Colombo, where approximately one in four people is affected by diabetes.

According to the International Diabetes Federation (IDF), around 1.6 million Sri Lankan adults aged between 20 and 79 were living with diabetes in 2024. Of these, approximately 603,000 people, or 37.7%, had not been diagnosed.

Medical experts have also raised concerns about increasing childhood obesity, warning that it could lead to more young people developing Type 2 diabetes.

Common symptoms of diabetes include frequent urination, excessive thirst, unexplained weight loss, tiredness and blurred vision. However, Type 2 diabetes can develop gradually without noticeable symptoms.

If left uncontrolled, diabetes can lead to serious health complications, including heart disease, strokes, kidney failure, vision loss and nerve damage.

Experts are urging the public to adopt healthier lifestyles, maintain a balanced diet, exercise regularly and undergo early medical screening to reduce the risk of diabetes.

This year's World Diabetes Day theme, "Early Action on Diabetes," highlights the importance of early diagnosis, timely treatment and preventive healthcare.
