I can provide some general information about anorexia and its effects on the body.
Anorexia nervosa is an eating disorder characterized by an intense fear of gaining weight, a distorted body image, and extreme efforts to restrict food intake, leading to significant weight loss. The timeline for becoming underweight can vary significantly from person to person and depends on various factors, including their initial weight, metabolism, activity level, and the severity of their eating disorder.
In some cases, individuals with anorexia may start losing weight rapidly due to extremely restricted food intake and excessive exercise. Others may develop the disorder more gradually over time, with weight loss occurring gradually as their eating habits become more restrictive.
It's important to note that anorexia is a serious mental and physical health condition with severe consequences. The body's response to prolonged malnutrition and inadequate nourishment can lead to numerous health issues, including weakness, fatigue, hair loss, changes in heart rate and blood pressure, hormonal imbalances, and damage to organs.
If you or someone you know is struggling with an eating disorder, it's crucial to seek professional help from a medical or mental health provider experienced in treating eating disorders. Recovery from anorexia is possible with appropriate treatment, support, and therapy.
