Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern...
As per your complain and presentation of symptoms Coeliac disease can be one of the cause of
bad breath which is due to gluten intolerance and for this you should consult a Rheuatologist and get a proper evaluation done..
A few other common causes for bad breath can be
Chronic Sinusitis,
dry mouth, oral infections, digestive problems,
diabetes etc..
You should get a through clinical examination done to rule out the exact cause of bad breath and get treated accordingly..
As of now to reduce the bad breath you can gargle with a flavoured mouthwash like Menthol containing twice a day to mask the bad breath..
Chew Sugar free chewing gums..
Nasal douching can help..
Do steam inhalations with a few drops of eucalyptus oil in it..
Maintain a good
oral hygiene..
Avoid strong aroma foods like garlic and onions and drink plenty of water..
Hope this information helps..
Thanks and regards..
