Diabetes is becoming a major health issue in Vietnam. Understanding the rapid rise and the large number of undiagnosed cases can help you protect your own health.

According to the National Hospital of Endocrinology, the share of Vietnamese aged 30‑69 with diabetes increased from 5.4 % in 2012 to 7.3 % in 2020, while pre‑diabetes grew from 13.7 % to 17.8 % over the same period. This means more people are at risk of developing the disease.

The hospital also reports that around 60 % of diabetes cases in Vietnam remain undiagnosed, and half of all adults have never been tested for the condition. Without a diagnosis, individuals cannot receive treatment and may develop serious complications without knowing why.

National Hospital data show that 55 % of diabetes patients have complications, including cardiovascular problems in 34 %, eye issues in 39.5 %, and kidney damage in 24 %. Such complications can limit mobility, increase medical costs, and affect everyday activities like work or caring for family.

Phan Hoang Hiep, director of the hospital, recommends early detection, a balanced diet rich in vegetables, regular exercise, and routine health check‑ups to lower the chance of complications. The National Hospital of Endocrinology sees more than 2,000 patient visits each day, most involving diabetes with complications. Following these steps can help keep blood sugar under control and preserve quality of life.

The key message is that diabetes is spreading fast in Vietnam, many cases go unnoticed, and complications are common. Getting screened and adopting healthier habits now can prevent serious health problems later.
