Which of the following can cause hypoglycemia?

Skipping meals can lead to hypoglycemia because when the body does not receive a regular supply of food, especially carbohydrates, it lacks the glucose needed to maintain normal blood sugar levels. Glucose is the primary energy source for the body's cells, and when meals are missed, insulin continues to function without adequate glucose to balance it, resulting in a drop in blood sugar levels. This situation is particularly critical for individuals with diabetes, who may already be managing their blood sugar levels with medication.

In contrast, too much food intake (one of the other options) typically results in elevated blood sugar levels rather than a decrease, as the body breaks down the food into glucose. Insulin resistance impacts the body's ability to use glucose effectively, which can lead to high blood sugar levels when there is an abundance of glucose available. Low blood pressure, while it may cause symptoms like dizziness or fainting, does not directly lead to hypoglycemia. Understanding the relationship between food intake and blood sugar levels is vital for managing conditions like diabetes effectively.
