Which of the following is a common cause of hypoglycemia in diabetics?

The selection highlighting skipping meals, excessive insulin, and intense physical activity as a common cause of hypoglycemia in diabetics is accurate because each of these factors can lead to a significant drop in blood glucose levels.

Skipping meals can cause hypoglycemia because without food intake, the body lacks the glucose it needs for energy. This is particularly critical for individuals taking insulin or other glucose-lowering medications, as their bodies may not have sufficient carbohydrates available to balance the insulin they have in their system.

Excessive insulin refers to the administration of too much insulin relative to food intake or energy expenditure. Insulin's primary role is to lower blood glucose levels, so if the dosage is higher than necessary, it can lead to hypoglycemia.

Intense physical activity can also deplete blood glucose levels, as exercising muscles require glucose for energy. When a person with diabetes engages in high levels of physical exertion without adjusting their carbohydrate intake or insulin dose, they may experience low blood sugar.

Overall, these factors are interrelated and often overlap in many diabetic cases, making this combination a well-known contributor to hypoglycemic events.
