During the medical history for diagnosis of hyperthyroidism, your doctor will ask you about other medical conditions you have had in the past, your family's medical history, and any medicines you are taking.

Your doctor will also ask other questions, such as:

• What is your usual weight, and have you noticed any changes in your weight, particularly a decrease in weight?
• How is your appetite, and have you noticed any changes in how hungry you feel, particularly an increase in appetite?
• How regular are your bowel movements, and have you noticed any changes in how often you have them?
• Have you noticed that your heart has been beating fast or feels like it is pounding in your chest?
• Have you had any problems breathing?
• Have you noticed any changes in your vision, particularly blurred or double vision, or do your eyes feel dry and itchy?
• Have you felt more tired than usual, felt weak, or had problems sleeping?
• Have you had any problems concentrating or felt excited or moody?
• Do you feel flushed or warm, or have you been sweating more than usual or felt uncomfortable in warm temperatures?

Doctors will ask women about any changes in their menstrual cycles and bleeding. They will ask men if they have noticed an enlargement of either breast.
