  1. Cardiovascular disease
  2. Nerve damage (neuropathy)
  3. Kidney damage (diabetic nephropathy) or kidney failure
  4. Damage to the blood vessels of the retina (diabetic retinopathy) which has the potential to cause blindness
  5. Blurring the normally clear natural lens of the eye (cataract)
  6. Foot problems caused by nerve damage or poor blood flow which can lead to serious skin infections, ulcerations, and amputation in some severe cases
  7. Bone and joint problems
  8. Tooth and gum infections
  9. Diabetic ketoacidosis: Diabetic ketoacidosis develops when diabetics do not have enough insulin in the body. When this happens, sugar (glucose) cannot enter the cells for energy production purposes. The blood sugar level then rises and the sufferer’s body begins to break down fat for energy. This process produces toxic acids known as ketones. Excess ketones can build up in the blood and urine. If left untreated, diabetic ketoacidosis can lead to a diabetic coma and be life-threatening
  10. Hyperosmolar hyperglycemia: This condition occurs when people produce insulin, but it doesn’t work well. Blood glucose levels can become very high, more than 1,000 mg/dL (55.6 mmol/L). Because insulin is present but not working properly, the body cannot use glucose or fat for energy. The glucose then spills into the urine, causing increased urination. If left untreated, the hyperosmolar hyperglycemic state can lead to life-threatening dehydration and coma. Urgent medical care is needed

Symptoms of high blood sugar in diabetics

Reported from Health Line, hyperglycemia often causes no symptoms until the blood glucose level increases significantly, usually above 180 to 200 mg/dL or 10 to 11.1 mmol/L.

Symptoms of hyperglycemia develop slowly over days or weeks.

The longer blood sugar levels remain high, the more serious the symptoms can become. However, some people who have had type 2 diabetes for a long time may not show any symptoms despite high blood sugar levels.

Recognizing the early signs and symptoms of hyperglycemia can help people with diabetes treat the condition quickly.
