Signs and Symptoms of Diabetes

Around 90% of diabetes cases are diagnosed as type 2 diabetes. Type 2 diabetes is a serious, potentially life-long condition that occurs when your pancreas can’t produce enough insulin and/or it produces ineffective insulin. Insulin helps keep your blood glucose levels stay at a safe level, but if your pancreas can’t keep up your blood sugar levels will rise.

Persistent high levels of blood sugar can lead to permanent damage to several parts of your body like the eyes, nerves, blood vessels, and kidneys. Your oral health, hearing, and vision can also be irreversibly affected.

The reason many people are unknowingly living with diabetes is because they aren’t experiencing any noticeable symptoms. Symptoms also tend to develop gradually over the course of several months or years, making them more difficult to notice.

  • Frequent urination
  • Extreme tiredness
  • Unexpected weight loss
  • Blurry vision
  • Frequent yeast infections
  • Excessive thirst
  • Slow healing wounds
  • Tingling or numbness in the hands and feet
