Anorexia nervosa is a serious eating disorder where people develop an intense fear of gaining weight and severely restrict their food intake. This leads to extreme weight loss, malnutrition, and life-threatening complications, including heart problems, electrolyte imbalances, and organ failure. Sree Nanda, a native of Meruvambai Thalassery, died on Sunday. She was being treated after surviving on only water for nearly six months. The teenager’s struggle with anorexia began when she turned to online weight-loss portals, following strict and unhealthy dieting methods. She ultimately resorted to consuming nothing but water for several months. Her body grew extremely weak, and by the time she was admitted to the hospital, she is said to have weighed only 24 kg. According to the National Institute of Mental Health, people with Anorexia often develop obsessive behaviours related to food, including restrictive eating, excessive calorie counting, and purging. This eating disorder can cause a range of complications, from cardiovascular issues like bradycardia and hypotension to gastrointestinal problems such as constipation and gastroparesis. In severe cases, patients may experience neurological effects, including brain atrophy and peripheral neuropathy, and renal complications.
