### input:
Good Morning - my 87 y/o father has been spitting mucous (sometimes it is as severe as vomiting mucous) - clear or whitish. one month ago, he spent the night in Emergency Dept of the local hospital whilst tests were run and MMR scan of his brain - apparently to rule out stroke, clotting, bleeds and brain tumour . He had a severe headache which was reduced with strong painkillers but took all night to recede. He has now been prescribed an anti-acid producing medication, but still has daily spitting episodes - not so much heaving or vomiting as he did when he experienced the severe episode that had him admitted. He is in OK health for his age !! and takes blood pressure meds daily, exalon patch daily, gout med (when required) and warfarin (just recently prescribed in the last few months - since the mucous problem started, so not related). Do you have any clues as to this excess mucous production Dr? (it is never greenish or yellow to indicate infection, but rather clear - like thickish saliva - and sometimes a little frothy. Thanks so much

### output:

Hi as per the information provided by you the source of mucus is the stomach not the chest. As per the history of gout where the patient suffers from gastritis also. The acidic pH of the stomach is irritating the gastric mucosa and making him feel nauseated, causing emptying of the stomach sometimes. Antacids along with regular intake of water will help keeping the gastric pH to near neutral .it will take a weeks time for the gastric irritation to go away, take care and keep the follow-ups with your gastroenterologist.
