1. Frequent urination
The technical term for frequent urination is polyuria. It means that there is so much glucose in the blood that the kidneys, unable to keep up, allow some to get excreted in the urine. This would make you have to urinate frequently, including at night.
2. Excessive thirst
Due to high level of blood glucose, and extra water-loss by frequent urination, you could find yourself feeling extremely thirsty. This may not be satisfied even after drinking water.
3. Increased hunger
Increased hunger tied with unexplained weight loss is another early warning sign of type 2 diabetes. The cells depend on glucose as a fuel to run its functions. In type 2 diabetes, the cells are unable to utilize glucose, leaving it to circulate in the blood. Due to lack of fuel, the cells are constantly on the lookout for more fuel leading to continued feelings of hunger.
Numbness is caused due to nerve damage or diabetic neuropathy. Feeling numb or tingling in your hands, fingers, feet, and toes is usually a sign of damaged nerves. This has been shown to be linked to type 2 diabetes. Although, this manifests in people who have been living with type 2 diabetes for several years, it could be an early sign for many.
5. Slow wound healing
There are two main reasons why type 2 diabetes leads to slower wound healing. First, accumulation of glucose in the bloodstream overtime makes the blood vessels narrow. This restricts essential nutrients and oxygen from reaching the site of injury in time.
6. Blurred vision
Again a manifestation of high blood glucose levels. High blood glucose levels affect the vessels that supply blood to the eyes. This leads to seepage of fluid into the eyes causing blurriness. When left unmanaged, this could lead to a more serious condition known as diabetic retinopathy. If you experience blurry vision, consult a doctor right away so that you can catch type 2 diabetes at an early stage.
7. Dark skin patches
Excess insulin in the blood is another result of type 2 diabetes. This leads to dark, velvet textured discoloration in the neck, armpits, and groins. This is another early warning sign of type 2 diabetes.
