Many people with type 2 diabetes do not know they are having this disease until the blood test shows abnormal blood glucose levels, or until the disease progresses and serious complications begin to occur.
Here are 5 strange symptoms that may be early signs of diabetes that you need to be aware of:
Gingivitis or infection
Periodontitis, also known as gingivitis, may be an early signal of type 2 diabetes. A study in the Journal named BMJ Open Diabetes Research & Care shown that people with gingivitis especially people who are more serious are at high risk for diabetes (both diagnosed and undiagnosed) and pre-diabetes are higher than those without the gingivitis.
The link between gingivitis and diabetes is not new and appears both ways: this disease increases the risk of developing that disease and vice versa.
A long time before you actually have diabetes, you may see dark skin changes in the back of your neck. This condition is termed a specialized term called acanthosis nigricans, and this is often a sign of insulin resistance – loss of sensitivity to the hormone that the body uses to regulate sugar – can actually lead to diabetes.
In rare cases, acanthosis nigricans can also cause ovarian cysts, hormones or thyroid disorders, cancer. Certain medications and supplements, including birth control pills and corticosteroids may be the cause.
Feeling strange at the feet
About 10% to 20% of people diagnosed with diabetes suffer from some neurological damages associated with this disease. In the early stages, this situation may be negligible. You may feel numbness in the legs or decreased sensitivity, loss of balance.
Of course, the strange feeling may be due to simple causes such as high heels, standing too long. But, it can also be caused by other serious conditions, such as scleroderma, so it is important to see a doctor as soon as this feeling arises.
Hearing loss or vision loss
High blood glucose levels can cause damages to the retina and cause fluid levels around the eyeball to change, causing you to look blurred or deformed. When blood glucose returns to normal level, vision is usually restored, but if diabetes is not controlled for a long time, the injury may be permanent.
In addition, high blood sugar can also affect the nerve cells in the ear and cause hearing loss.
A long midday nap
A scientific assessment shows that people who have a long midday nap are 45% more likely to have type 2 diabetes than those who do not sleep well.
The authors argue that it is not a long midday nap that causes diabetes, but it may be a warning sign of internal disorders such as lack of sleep, depression, or sleep apnea, all of which are related to increase the risk of diabetes.
