What are some signs of insulin overdose?

Signs of insulin overdose include symptoms related to hypoglycemia, as an excess of insulin can lower blood glucose levels significantly. The correct choice lists weakness, ataxia, shaking, and seizures, which are all indicators of a dangerously low blood sugar level. When there is too much insulin in circulation, it drives glucose out of the bloodstream and into the cells, leading to insufficient glucose available for the body’s energy needs.

Weakness may occur as the body's muscles and organs lack the energy they require, while ataxia, which refers to impaired coordination and balance, can result from nervous system impairment due to low glucose levels. Shaking or trembling is a common physical response to hypoglycemia as the body attempts to mobilize glucose stores. In severe cases, seizures can occur as brain function is disrupted by the lack of glucose, which is critical for normal neuronal activity.

The other options reflect symptoms associated with different conditions. For example, vomiting and diarrhea do not typically arise from insulin overdose. Instead, these symptoms may indicate gastrointestinal distress from another cause. Excessive thirst and urination commonly relate to conditions like diabetes mellitus rather than insulin overdose. Finally, fever, increased appetite, and irritability are also not characteristic of insulin overdose and might signify other
