What's the matter with sty in upper eyelid

1, diet factors: if the patient eats too much spicy stimulation, raw and cold greasy food, may stimulate the meibomian gland to produce a large number of secretions, causing blockage of the meibomian gland, and breeding bacteria, leading to purulent inflammation of the meibomian gland, causing styes.

2, improper eye cleaning: if the patient often uses dirty hands to rub the eyes, it will lead to bacterial infection of the meibomian gland, purulent inflammation, causing styes.

3, conjunctivitis: if the patient with conjunctivitis can not be cured for a long time, the pathogen at the conjunctiva may affect the meibomian gland, causing infection of the meibomian gland, causing styes.
