Mucus colour - a year after treatment

I have just remembered he ate beetroot last night so have read that can cause a change in mucus colour.

Yes. When I spit, hours after a black coffee it’s still tinged brown. 
Avoid beetroot for a couple of days and monitor. 
Another thing you can do  is see if there is any blood on a urine dipstick. If there is then co tact his CNS to get him seen. 

Beetroot can do that, can also give urine a red tinge which can give some of us a massive fright....

Hi Worrylo.

The beetroot is probably the cause, but keep an eye on it, just to be sure.  My OH is four months post RT but I need to keep alert for chest infections as his lungs are prone, due to the nature of his surgery.  A few weeks ago, I took him off to A&E as his mucous had a green colour; sure enough it was an infection and after a chest x-ray, IV and obs, he got discharged with antibiotics, which cleared it.

I'm sure your hubby will be fine, but you do right to remain vigilant.  Hugs xxx

My mucus is certainly coloured by whatever I have been consuming (or trying to consume).  But if the colour is still re after he has eaten other foods or you are worried, I am sure there is no harm in getting a check-up.
