Top 10 Diabetes Symptoms

Symptoms of diabetes are caused by higher levels of glucose (sugar) in your blood. Both types of diabetes (type 1 and type 2) have some of the same warning signs. Symptoms tend to develop more quickly for type 1 diabetes compared to type 2 diabetes.

Have you or someone you care for experienced any of the following symptoms?

increased urination

Increased urination When blood glucose levels are elevated, you may not reabsorb all of the glucose as it passes through the kidneys. Your body will try to get rid of it by making more urine.


Increased thirst As a result of increased urination, you may get dehydrated, and will therefore be drinking more than usual.


Fatigue (feeling tired or lethargic) Glucose provides you with energy. Your cells need insulin to bring the glucose in. If your body doesn't produce enough or any insulin, the glucose has no way of entering the cells and you have no energy. This can make you tired.


Blurred vision When blood sugar levels are increased, fluids can leave the lenses of your eyes, causing vision changes.

numbness in feet

Numbness or tingling in the hands or feet Damage to the nerves can result from elevated blood glucose levels causing what is known as 'peripheral neuropathy'.

These might be signs of diabetes.


Other signs or symptoms include:

  • weight loss (usually seen with type 1 diabetes)
  • slow-healing cuts and bruises
  • frequent or recurring infections
  • trouble getting or maintaining an erection
  • persistent vaginal infections

If you have any of the above symptoms, make an appointment to see your doctor. A blood test will help determine if these symptoms might be caused by diabetes.

Remember the good news

You can take steps to manage your blood glucose to help delay or prevent the onset of type 2 diabetes. Blood glucose levels can often be reduced through basic lifestyle changes such as following a healthy eating plan and starting a program of regular physical activity.
