In addition to oral and gastrointestinal problems, the odour when sneezing is generally considered to be related to the function of the nasal cavity. The self-detoxification system of the nasal cavity does not work properly and cannot remove the dust, bacteria and other dirt that constantly enters the nasal cavity with breathing in a timely manner, resulting in a bad smell.
If it is an oral problem, pay attention to oral hygiene, brush your teeth in the morning and evening and rinse your mouth after meals to avoid oral food residue.
If it is a gastrointestinal problem, use some intestinal probiotics and avoid spicy, stimulating, greasy and cold foods.
If it is a nasal problem, relevant tests need to be done to confirm the diagnosis of the disease before treating it symptomatically.
