If you have diabetes, it is important to know the early signs of hyperglycemia. If hyperglycemia is left untreated, it may develop into ketoacidosis (if you have type 1 diabetes) or HHNS (if you have type 2 diabetes), both of which are serious emergencies.
Early signs of hyperglycemia in diabetes include:
Fatigue (weak, tired feeling)
Blood sugar more than 180 mg/dL
Prolonged hyperglycemia in diabetes may result in:
Vaginal and skin infections
Slow-healing cuts and sores
Nerve damage causing painful cold or insensitive feet, loss of hair on the lower extremities, and/or erectile dysfunction
Stomach and intestinal problems such as chronic constipation or diarrhea
