Hypoglycemia, or low blood sugar, can lead to a variety of symptoms reflecting the body's response to decreased glucose availability for energy. Fatigue, confusion, and nausea are indeed common symptoms of hypoglycemia. When blood sugar levels drop, the brain and body's functions become impaired, which can manifest as confusion and difficulty concentrating. Additionally, individuals may experience fatigue because their bodies lack the necessary energy to perform optimally. Nausea can occur as a physiological response to the distress caused by low blood sugar levels. Recognizing these symptoms is essential for prompt intervention, such as consuming fast-acting carbohydrates to raise blood sugar levels.

The other options listed reflect symptoms that are not characteristic of hypoglycemia. Weight gain and increased appetite tend to be associated with conditions of excess energy or hormonal imbalance. Insomnia and muscle cramps are not directly related to low blood sugar and instead might point to other health issues or side effects. Persistently high energy levels contradict the very nature of hypoglycemia, which is characterized by low energy and functioning in both physical and cognitive domains.
