Hyperglycemia is when there are abnormally high levels of blood sugar.  When we eat, our bodies receive glucose.  A hormone called insulin then helps the glucose move into the cells to give them energy.  Hyperglycemia occurs when the body doesn’t produce enough insulin, or the body can’t use the insulin properly.  Due to this, hyperglycemia is often a hallmark sign of diabetes (1).

  • In 2015, 84.1 million Americans over the age of 18 had prediabetes, and 30.3 million Americans, or 9.4% of the population, had diabetes.  Of the 30.3 million Americans, an estimated 7.2 million were undiagnosed.
  • The total cost of diabetes and pre-diabetes in the US in 2017 was $327 billion.
  • Healthcare costs 2.3 times more than those without diabetes (5).


Because hyperglycemia usually is caused by diabetes.  Most people are treated for diabetes.  Listed below are a few medications prescribed for those with diabetes.

  • Meglitinides: marketed as Starlix and Prandin. Possible side-effects include weight gain, low blood sugar
  • Biguanides/Metformin: Possible side-effects include sickness with alcohol, kidney complications, upset stomach, tiredness or dizziness, metal taste
  • Sulfonylureas: marketed as Diabinese, Amaryl, Glucotrol, Micronase, Tolinase, Orinase.  Possible side effects include low blood sugar, upset stomach, skin rash or itching, weight gain
  • Thiazolidinediones: marketed as Actons, Avandia.  Possible side-effects include weight gain, risk of liver disease, anemia risk, swelling of legs or ankles
  • Insulin: Possible side-effects include low blood sugar, headaches, rashes, dizziness, anxiety, cough, and dry mouth (6).
