This kind of seems like anemia to me but you should definitely go see a doctor if thats happen it could be alot my serious like maybe the Big C? (cancer)What would cause these symptoms...?
Cancer. tumors could be constricting blood vessels, causing dizziness and head aches. tumors also effect your metabolic rate, causing digestive problems, that in turn can cause stomach aches, and it is common knowledge cancer causes hair to fall out. depending on the cancer and what stage you are in, the bruising could be indicative of lymph node swelling, which is common with brain cancer. i suggest getting an immediate CT scan of your brain to determine which stage the cancer is in, overall survival rates are between 5 and 20%. less than half but atleast you have a shot.
i think you might probably be having hyperthyroidism. are you currently experiencing some weight loss? I had a classmate who has hyperthyroidism and she experienced some hairloss and bruises sprouted from her out of nowhere. Check it with your doctor for confirmation.
