Energy depletion spans every system

A lack of energy is rarely isolated to one symptom or one body system. It can affect the cardiovascular system, the nervous system, the digestive tract, the skin, and mental health simultaneously. This is because life energy — in both its physiological and holistic sense — underpins the functioning of every organ and process. Recognising where symptoms sit on the severity spectrum is the critical first step.
