[|Human|] every morning when I am about to refresh my face I spit blood, it is not red but brownish, I imagine it is blood mixed with saliva. After 2-3 spits the brownish colour disappears and I spit white as usual and I am fine during the day. What is it? it is a sign of cancer? could it be the gums or the stomach? has anyone got the same? I am 54 years old, I do not smoke, I do not drink. Thanks for answers
[|AI|]  Thanks for your query, I have gone through your query. The blood mixed saliva while spitting is because of the gum infection. Particular;y during night the salivary secretion will be reduced or almost nil because of the lack of stimuli, so there won't be any antibacterial activity, so there will be increased activity of microorganisms. Nothing to be panic, it is not cancer. Smoking can increase the risk of gum infection and bleeding, is better stop smoking. For gum infection, get your teeth cleaned and use topical gum astringents like stolen gum paint. I hope my answer will help you, take care.
