The symptom most closely associated with hypochondria is excessive fear of having a serious illness. Hypochondria, also known as health anxiety, is characterized by an obsessive worry about one's health, where individuals often misinterpret normal bodily sensations as signs of severe medical conditions. This intense preoccupation can lead to significant distress and can be quite debilitating, as those affected frequently seek medical reassurance and can become preoccupied with their health status.

While consistent fatigue, high levels of stress, and loss of appetite may occur alongside hypochondria, they are not defining symptoms. These can be associated with various other mental health conditions or physical illnesses but do not specifically indicate the presence of health anxiety like the fear of having a serious illness does. Thus, the correct answer highlights the core element of hypochondria, which is the intense fear and concern about health.
