Final answer:
In diabetes mellitus, the complication that can arise from injecting too much insulin, inadequate food intake, or too much exercise is hypoglycemia, a condition where blood glucose levels become dangerously low.
Step-by-step explanation:
In diabetes mellitus, injecting too much insulin, not receiving adequate food intake, or exercising excessively can cause the complication known as hypoglycemia.
Diabetes mellitus is a condition characterized by imbalances in blood glucose levels due to problems with the hormone insulin. People with diabetes have high blood glucose levels, known as hyperglycemia, because of deficient insulin production or insulin resistance in cells.
However, if a person with diabetes injects too much insulin or does not consume adequate food, or exercises more than necessary, their blood glucose levels can drop too low, leading to hypoglycemia. This can cause symptoms such as sweating, tremors, fainting, and in severe cases, unconsciousness or death if left untreated. Immediate treatment is usually required to bring blood glucose levels back to normal, typically by oral or intravenous sugar.
