INSIDER Logo By Julia Naftulin of INSIDER | Slide 1 of 7: 
  High blood sugar or hyperglycemia happens when a person's
  body doesn't properly make or use the hormone insulin. Insulin
  helps the body convert the glucose from foods into energy.
  
  High blood sugar doesn't only affect people with
  diabetes. It can also come about from infections, stress, inactivity,
  and other issues. 
  
  Signs that you have high blood sugar include being constantly
  tired or thirsty, experiencing chronic headaches, and having
  blurred vision.

  When you hear the term "high blood sugar," it's likely you think
  of people who are diagnosed with diabetes and need insulin to
  keep their bodies in equilibrium. But high blood sugar or
  hyperglycemia can affect people without diabetes too. And, if
  left untreated, it can lead to nerve damage or 
  kidney, eye, or heart disease.

  High blood sugar happens when a person's body doesn't produce or
  properly use 
  enough of the hormone insulin, which helps turn the food you
  eat into usable energy in your body. As a result, a person may
  feel fatigued all the time, constantly thirsty, have blurred
  vision, or experience a host of other symptoms. These symptoms
  don't pop up right away and can 
  take days or weeks to develop as a person's blood sugar
  levels continue to rise, according to the Mayo Clinic.

  Besides having Type 1 or Type 2 diabetes, having an infection,
  being inactive, being under stress, and eating too many
  carbohydrates can lead to high blood sugar. People with
  cystic fibrosis and those who take beta-blocker
  medications may also have any increased risk for developing
  high blood sugar.

  To be diagnosed with high blood sugar, you'll need a blood test
  to determine if your glucose levels are too high. See a doctor
  for a test as soon as possible if you notice any of these six
  signs.
