[|Human|] Hello there,While visiting my sister this weekend, I noticed that her breath smells extremely strongly like a combination of blood and metal. I dont want to mention it to her unless there may be need for an appointment with her doctor as I realize it may be taken as offensive. Any insight?
[|AI|]  Hello read through your query and I feel happy for you to be caring about your sister. I must say that you must tell your sister about this as it's her brother who is telling and she won't feel offended. But she will be offended and extremely sad when someone else tells her this. Now coming to the cause. Bad breath can be caused by numerous causes. It can be due to various systemic causes like diabetes starving kidney disease liver disease etc. In oral cavity it can be due to lack of oral hygiene. Please advice her to do brushing twice daily use clothes mouthwash do tongue scraping also Chat Doctor.
