People with anorexia nervosa find it difficult to get over it, but with treatment they can regain their normal healthy eating habits. They experience both emotional and physical symptoms. Some of the symptoms include constipation, fatigue, insomnia, fainting, extreme weight loss, abnormal blood counts, dehydration, swelling, social withdrawal, irritability, fear of gaining weight and intense exercise. Anorexia may also cause other conditions, including anxiety, misuse of alcohol, depression and low self-esteem.

When a person fails to eat healthily, the body fails to get nutrients and energy. Unfortunately, people with anorexia nervosa may not often recognize they have a problem, and they tend to be comfortable with their lifestyle, as stated by the NHS. Some cannot accept that they are facing a problem when approached. The desire to lose weight overrides any possible health risks. Dietitians and specialist nurses can help such people to manage their condition.
