Menorexia refers to the stopping of menstrual cycles as a result of severe dieting or disordered eating and can lead to bone loss, hormonal imbalances, metabolic problems, and mental health problems. It's made of two words, 'meno' (menopause) and 'anorexia' (eating disorder). Sudden weight loss, persistent fatigue, and feeling cold even in warm settings are some of its early symptoms.
