<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, Ive been feeling weak and tired and my muscles ache a lot. I also have been having lots of fractures lately. Can you tell me what is wrong with me?  <response>: It seems like you might have a vitamin D deficiency. To confirm this, we will need to perform a blood test, glucose level measurement, lipid panel, complete physical skin exam, hemoglobin A1c measurement, depression screening, and a bone density scan.
