Type 2 diabetes is the most common form of diabetes mellitus, a complex metabolic disease which increases blood glucose. It is characterized by frequent urination, blurry vision, tiredness, increased thirst and hunger, numbness, and more.
In 2017, this chronic disease affected more than 30 million Americans (1). Globally, the International Diabetes Federation estimates that the number of adults with diabetes will increase to 629 million by 2045 (2).
In front of these daunting numbers, it’s important to spread awareness about the early signs of diabetes and diagnose it early.
The good news is that primary prevention of diabetes is possible through behavior and dietary modifications. Early diagnosis is key to delay or even reverse the onset of some of the risk factors for this disease, and thus mitigate its burden.
Although your physician should be checking your blood glucose levels during your periodic screenings, there are some subtle symptoms of hyperglycemia that aren’t manifested immediately and may remain undiagnosed for several years.
Read on to recognize your body’s hints of type 2 diabetes in order to prevent further complications.
2. Blurred Vision
Patients with prediabetes or type 2 diabetes often experience signs of blurred vision associated to hyperglycemia. This is potentially due to changes in the retina, blood sugar swings or changes in the lenses.
One study on macular edema, also known as retina thickness, in patients with diabetes found that the latter exerts harmful effects on the blood vessels of the retina, and thus prevents your eyes from functioning properly (5).
On the long term, prolonged hyperglycemia may induce diabetic retinopathy which leads to complete loss of vision.
