Hello welcome to health care magic In the query you didn t mention about the menses,,is there any over flow that is more bleeding..in general females have low hemoglobin and low iron level because of monthly losses due to menses.. Regarding the above said symptoms they are symptoms of iron deficiency... Take a routine blood test in that hemoglobin levels are mentioned.. Also take hemogram,,it will tell you the cause of low hemoglobin .. Consult gyneccologist(if you have heavy periods)/physician and he will prescribe iron tab.,, Mean while take good diet which is rich in iron like jaggery,nuts,meat etc.. Regarding hair loss,,it might be dut to stress,genetic issues or doe to iron deficiency also..consult trichologist. Hope you understand my suggestion and answer. Thank you Dr.siddartha
