What diseases can allergic rhinitis trigger?

Generally, allergic rhinitis can lead to complications such as allergic conjunctivitis, nasal polyps, sinusitis, otitis media with effusion, and asthma. If you experience any discomfort, it is advisable to seek timely medical evaluation and treatment at a reputable hospital. A detailed analysis follows:

1. Allergic Conjunctivitis

The allergens responsible for allergic rhinitis may spread to the eyes via the nasolacrimal duct, irritating the conjunctiva and triggering inflammation—manifesting as ocular pruritus, tearing, and conjunctival hyperemia. Under medical supervision, symptoms may be alleviated using ophthalmic solutions such as olopatadine hydrochloride eye drops, emedastine fumarate eye drops, or azelastine hydrochloride eye drops. Simultaneously, avoid exposure to known allergens and refrain from rubbing your eyes.

2. Nasal Polyps

Chronic, recurrent inflammation associated with allergic rhinitis may cause nasal mucosal congestion, edema, and hyperplasia, resulting in translucent, lychee-like growths that obstruct the nasal passages and impair breathing. Under medical guidance, intranasal corticosteroids—including mometasone furoate nasal spray, fluticasone propionate nasal spray, and budesonide nasal spray—may be used to control inflammation. For larger polyps, endoscopic nasal polypectomy may be required.

3. Sinusitis

Allergic rhinitis-induced nasal mucosal swelling may obstruct the sinus ostia, preventing normal drainage of sinus secretions and predisposing to secondary bacterial infection and subsequent inflammation—characterized by purulent nasal discharge and headache. Under medical supervision, treatment may include cefdinir capsules, amoxicillin–clavulanate potassium tablets, or eucalyptus-citrus-pine enteric-coated soft capsules. Concurrent nasal irrigation is recommended to facilitate secretion clearance.

4. Otitis Media with Effusion

Inflammation originating in the nasal cavity may extend to the eustachian (auditory) tube, causing obstruction and dysfunction, leading to middle ear fluid accumulation—resulting in aural fullness and hearing loss. Under medical guidance, ambroxol hydrochloride oral solution, cefaclor capsules, and mometasone furoate nasal spray may be prescribed. In cases of substantial effusion, tympanocentesis may be performed to aspirate the accumulated fluid.

5. Asthma

Both allergic rhinitis and asthma are airway hyperresponsiveness disorders. Uncontrolled upper airway inflammation may extend into the lower airways, precipitating asthma—manifesting as wheezing, chest tightness, and cough. Under medical supervision, management may include salbutamol inhaler, budesonide–formoterol dry powder inhaler, and montelukast sodium chewable tablets to systematically control airway inflammation.

In daily life, avoid common allergens such as pollen and house dust mites; ensure adequate indoor ventilation; wash bedding regularly to minimize allergen accumulation; maintain regular sleep patterns and strengthen overall physical fitness; avoid spicy and irritating foods; and undergo routine follow-up examinations to promptly manage rhinitis symptoms and prevent complications.
