<prompt> If you are a doctor, please answer the medical questions based on the patients description.My boyfriend is not feeling well, he is clammy and has had a dull headache. His head feels slightly warm. He also is stating that his heart is beating a little fast. He drinks alot of coffee during the day but today waited about 2 hours after he got up. He hasnt been eating well, greasy foods and sometimes just once a day but claims he ate about 5 times today. He also smokes cigarrettes, but has had only two today. What could br wrong with him?  <response>: Hello, I would explain that his symptoms could be related to a metabolic disorder or anxiety. For this reason, I would recommend performing some tests in order to investigate a possible metabolic disorder: - complete blood count for anemia-thyroid hormone levels for thyroid gland dysfunction- blood electrolytes for possible imbalance. If these tests result normal, I would recommend consulting with a psychologist or psychiatrist in order to help improve his situation. Hope I have answered your query. Let me know if I can assist you further.
