hyperglycemia vs. hypoglycemia
The root glyk- means "sweet" in Greek, so glyc shows up in the names of various terms referring to a sugar as a chemical ingredient, such as glycerol and monoglyceride. People with diabetes have difficulty controlling the sugar in their blood. Too little sugar in the blood, called hypoglycemia, can be dangerous; its early symptoms may be as minor as nervousness, shaking, and sweating, but it can lead to seizures and unconsciousness. Luckily, it can be taken care of easily by eating or drinking something high in carbohydrates. Its opposite, hyperglycemia, is an excessive amount of sugar in the blood and is the main symptom of diabetes mellitus. Acute hyperglycemia usually requires an injection of insulin.
