Anorexia is a serious eating disorder that can affect people of all body sizes and backgrounds. Symptoms of anorexia may include physical signs like low heart rate, dizziness, digestive issues, and hormonal changes, as well as behavioral and emotional warning signs such as food restriction, fear of weight gain, compulsive exercise, and social withdrawal. Some individuals experience severe medical complications even if they do not appear underweight, a condition known as atypical anorexia. Recognizing early signs and seeking timely treatment can support recovery and reduce health risks.
