Are You One of the Undiagnosed? New Study Finds Nearly Half of Diabetes Cases Are a Secret
A shocking new study reveals that nearly half of all people living with diabetes don't know they have it. The research, published in the journal The Lancet Diabetes & Endocrinology, analyzed data from 204 countries and found that 44% of people aged 15 and older with diabetes are undiagnosed. This "hidden half" means millions of people are unknowingly living with a serious health condition that can lead to severe complications.
The Diabetes Disconnect
The study's lead author, Lauryn Stafford, explained that the majority of these undiagnosed cases are type 2 diabetes. While about 1 in 9 adults globally have diabetes, the research found a significant gap in awareness. Only 56% of people with the condition are aware of their diagnosis. This awareness varies greatly by region, with higher-income countries generally doing a better job of screening their populations than lower- and middle-income countries.
Young People Are Missing Out on Diagnosis
One of the most concerning findings is the lack of diagnosis among young adults. The study found that a staggering 80% of young adults with diabetes are unaware of their condition. This is likely because routine screenings are more commonly recommended for older adults. The American Diabetes Association, for example, suggests annual screenings for people ages 35 and older.
Stafford noted that people can live with elevated blood sugar for years without major symptoms, often leading to a diagnosis only after serious complications arise. This is why early detection is so critical. According to Dr. Rita Kalyani, a chief scientific and medical officer at the American Diabetes Association, early diagnosis allows for timely management to prevent long-term issues like heart disease, kidney failure, nerve damage, and vision loss.
Know the Symptoms and Get Screened
Since many people with early-stage diabetes don't show symptoms, screening is essential. However, it's also important to be aware of the signs. Dr. Kalyani says symptoms can include:
- Increased thirst or hunger
- Frequent urination
- Blurry vision
- Unexpected weight loss
- Fatigue
If you experience any of these symptoms or have a family history of diabetes, experts urge you to get a glucose screening.
Even for those who are diagnosed, the battle isn't over. The study found that only about 40% of people with treated diabetes are seeing optimal results, despite the availability of effective medications like insulin and metformin. This highlights the need for better post-diagnosis care and support.
