How to Do a Unit Rate. A unit rate describes how many units of the first type of quantity corresponds to one unit of the second type of quantity. A good example of a unit rate is miles per hour, with miles being the first quantity and hours being the second. Unit rates are included in the core of many math and physics problems.
Low Blood Sugar Symptoms. A low blood sugar, also called hypoglycemia or an insulin reaction, is defined as a blood glucose level below 60 to 70 mg/dl. It is usually companied by one or more of the symptoms described below. Low blood sugars or insulin reactions can occur whenever insulin is used.
Hypoglycemia refers to blood sugar levels that drop below the normal range. When blood sugar becomes too low, the body releases a hormone called epinephrine, which causes the body to release stored sugar into the blood. Epinephrine produces symptoms such as hunger, sweating, and shaking. As blood sugar drops even more, the body cannot get enough sugar to the brain, and additional symptoms develop due to the decrease in sugar to the brain. This causes dizziness, confusion, and weakness. As blood sugar continues to drop, and the brain does not have enough sugar to function properly, more severe effects occur, including permanent brain damage, seizures, coma, and death.
