A wide range of symptoms can indicate one of a number of different eating disorders. Symptoms can include: chronically eating too much or eating too little; binge eating and/or severely restricting food intake; intentional vomiting and/or over-exercising to compensate for eating; distortions in the way that you think you look compared to the way you actually look; spending most of your time thinking about food, diet, weight and shape; being overweight or underweight, or even of normal weight for your height but with many of the other symptoms listed above.

At PsychSessions we take a multi-disciplinary approach to the diagnosis and treatment of eating disorders. You will receive a thorough assessment by one of our psychologists, who has special training and experience in eating disorders. The assessment will include your current diet, eating habits, exercise, body image, mental health, and other lifestyle factors. The psychologist will then liaise with your GP and dietician to foster a collaborative approach with regard to your diagnosis and treatment, if necessary. All treatment programs are individually tailored according to your specific condition and symptoms.

All psychologists at PsychSessions have some training and experience in eating disorders. However, the following psychologists have a special interest in eating disorders and have worked or been trained in a specialist eating disorders unit, and where indicated have or are conducting research at a university into eating disorders.
