Hyperglycemia occurs when people with diabetes have too much sugar in their bloodstream
symptoms of hyperglycemia
High blood glucose
High levels of sugar in the urine
Frequent urination
Weakness or feeling tired
Increased thirst
Vision blurring
When a person with diabetes has hyperglycemia frequently or for long periods of time, damage to nerves, blood vessels, and other body organs can occur. If left untreated, it can lead to Ketoacidosis.

Hypoglycemia is a condition characterized by abnormally low blood glucose.
symptoms of hypoglycemia
shakiness
sweating, chills and claminess
lightheadedness, dizziness
blurred/impaired vision
In people with diabetes, hypoglycemia develops when there is not enough sugar in your body to be used as fuel for cells. It can occur in someone with diabetes following a meal that contains a lot of simple sugars. It may also develop if a person with diabetes misses a snack, doesn't eat the whole meal, eats later than usual, doesn't eat when ill, or drinks alcohol without eating any food.

22. Describe what would happen to cells that are exposed to Isotonic, Hypotonic, and Hypertonic solutions. 2.3.2
A hypotonic solution has a low concentration of solute. When a cell, which is composed of 70% water and 30% solute, is exposed to a hypotonic solution, the cell gets larger. The concentration of water outside the cell is higher than within the cell, creating an imbalance. In order to maintain equilibrium, water outside the cell travels through semi- impermeable membrane, since concentration travels from high to low. Eventually, the same concentration of water can be found in both environments.
A hypertonic solution has a high concentration of solute. The cell exposed to a hypertonic solution will shrink. Since solute can not travel through the semi- impermeable membrane into the cell because is it too big, water travels outside the cell to maintain homeostasis.
An isotonic solution has the same concentration of solute as the cell. The cell will remain the same size because an equilibrium exists.
