Final answer:
Excess insulin can lead to hypoglycemia, where blood sugar levels drop too low, and may manifest as sweating, tremors, and fainting attacks. Hypoglycemia is a condition to be carefully managed in insulin therapies for treating diabetes mellitus.
Correct option is A
Step-by-step explanation:
The student asked about the consequence of excess insulin in the body, and the correct answer is hypoglycemia, which is a condition where the blood sugar levels drop too low. This condition can be dangerous as it may lead to symptoms such as sweating, tremors, and fainting attacks. Notably, an improper dosage of insulin in the treatment of diabetes mellitus can lead to this condition. Conversely, missing a dose of insulin in diabetic individuals can cause ketoacidosis, especially among those of Hispanic and African-American descent, but this is not the result of excess insulin.
Diabetes mellitus itself involves complications related to the body's use of glucose, often leading to high blood sugar levels, or hyperglycemia, and ketoacidosis when not properly managed with insulin therapy or other treatments.
