R63: Symptoms and signs concerning food and fluid intake

R63.0: Anorexia

Anorexia, symbolized by ICD-10 code R63.0, refers to a loss of appetite, which can lead to severe weight loss and malnourishment. This condition does not involve a fear of gaining weight, a characteristic of anorexia nervosa, which is a separate mental health disorder. Anorexia can stem from various factors, including stress, other illnesses, or treatments such as chemotherapy. Common symptoms include lack of interest in food, decreased energy levels, and sudden weight loss. The progression of anorexia can potentially affect various bodily systems, leading to a myriad of health issues, including anemia, bone loss, and a weakened immune system. Recognizing anorexia’s potential harmful effects is crucial for early intervention, which can ultimately aid in restoring a healthy relationship with food and nutrition.
