Glen is 35 years old and a little overweight. He is getting married in a few weeks and wants to lose a few pounds before the ceremony. He is extremely conscious of his weight. He has given up alcohol and stopped smoking, and he is now trying to cut down on fatty foods and sweets. He is finding it difficult to change his eating habits. His friend recently found him throwing up frequently after meals. Glen’s teeth are discolored, and his cheeks are swollen. Clearly, Glen is suffering from an eating disorder.'
