Introduction
An unpleasant odor accompanying sneezing may be caused by improper dietary habits, dry nasal passages, sinusitis, periodontal disease, or nasal polyps. Use saline solution to rinse the nasal cavity to clean out secretions and bacteria, which helps reduce the source of odor. Brush teeth regularly and rinse the mouth frequently to maintain oral hygiene. It is recommended to brush or rinse after every meal to remove food debris and bacteria.
Generally, bad odor accompanying sneezing may be caused by improper dietary habits, dry nasal passages, sinusitis, periodontal disease, or nasal polyps. If discomfort occurs, seek medical attention promptly. Specific analyses are as follows:
1. Improper Dietary Habits
After digestion and absorption, compounds from certain foods can be partially expelled through the respiratory system. When sneezing, these compounds may be released along with airflow, causing an unpleasant odor. Adjust dietary habits by reducing intake of strongly-scented foods and rinsing the mouth after meals to maintain oral hygiene.
2. Dry Nasal Passages
A dry nasal environment can cause nasal secretions to dry and harden. When sneezing, these dried secretions may emit an unpleasant smell. Use saline nasal sprays or nasal drops to moisten the nasal cavity, maintain indoor air humidity, and drink plenty of water.
3. Sinusitis
Sinusitis can be triggered by factors such as smoking and air pollution. Inflammatory secretions from the sinuses contain large amounts of pus, where bacteria multiply and produce foul-smelling gases. Symptoms may include nasal congestion and headaches. Follow a doctor's instructions to use medications such as amoxicillin-clavulanate potassium tablets, cefixime dispersible tablets, or azelastine fluticasone nasal spray for treatment.
4. Periodontal Disease
Periodontal disease is an inflammatory response caused by dental plaque adhering to teeth and leading to infection. Gingival inflammation and bacterial proliferation in periodontal pockets generate foul gases such as hydrogen sulfide, which may exit through the nasal passages and cause bad odor. Symptoms may include bleeding gums and loose teeth. It is recommended to follow medical advice and use medications such as metronidazole tablets, tinidazole tablets, or ornidazole tablets for treatment.
5. Nasal Polyps
The development of nasal polyps is associated with pathogenic microorganisms, genetic factors, and others. Nasal polyps can block nasal passages, impair airflow, and lead to accumulation and fermentation of secretions, resulting in odor. Symptoms may include nasal congestion and headaches. Under guidance from a qualified physician, medications such as budesonide nasal spray, cetirizine tablets, or prednisone acetate tablets may be used for treatment.
Nasal irrigation with physiological saline helps clean nasal secretions and bacteria, thereby reducing sources of unpleasant odor.
