Hi and thank you so much for this query. I am so sorry to hear about these nose bleeds. Though most nose bleeds really have no cause and get to be resolve all by themselves, we need to look for common cause and address. If this has not been done, then please ask your doctor to look into. As for drinking water, it is good to replenish the loss but how much blood do you loss during a bleeding episode? If it is much, then please make sure you get a proper assessment and management. If the volumes are small, then that is fine. Also, consider getting iron supplements because repeated losses would eventually lead to anemia unless iron stores are replenished. I hope you find this helpful. Thank you so much for using our services and feel free to request for more information if need be. I wish you the best of health. Thanks. Dr. Ditah, MD
