Hi..
Welcome to HEALTHCARE MAGIC..
As per your complain bad breath also known as Halitosis can occur due to a number of causes like poor
oral hygiene, oral and dental infections, tonsil stones or tonsilloliths,
post nasal drip, sinusitis,
acid reflux,respiratory infections, diabetes etc..
In case if you have acid reflux which is appearing evident from the symptoms that you are experiencing you should continue taking antacids and
proton pump inhibitors like
Omeprazole and also avoid spicy and acidic foods..
Take more of yoghurt in diet and drink plenty of water..
Do moderate workout..
You should also consult an Oral Physician or an Otolaryngologist and get evaluated and a thorough clinical evaluation and investigations depending upon suspected cause can help in diagnosis..
Treatment of underlying cause will relieve the symptoms..
As of now you should start gargling with a flavoured mouthwash twice a day..
You should chew flavored sugarfree chewing gum..
Do warm saline gargles twice a day..
Limit the intake of high aroma foods like onion and garlic..
Drink plenty of water and maintain a good oral hygiene.
Hope this information helps..
Regards.
