Rosacea, also known as rosacea, has an unknown etiology and pathogenesis, which may be related to genetic factors, emotional factors, mite infections, and spicy stimuli.
1. Genetic factors: If there is a family history of rosacea, the next generation will have a higher chance of developing rosacea.
2. Emotional factors: Anxiety and depression can cause endocrine disorders, leading to vasodilation and vascular hyperreactivity, which may also trigger rosacea.
3. Mite infection: Follicular helminth mites can stimulate surface antimicrobial peptides and participate in immune-induced reactions, thus causing localized inflammatory reactions and vasodilatation leading to rosacea.
4. Spicy stimulation: Alcohol, chili peppers and other spicy foods can stimulate peripheral nerves and release neuromediators, thus triggering rosacea.
There may be other causes of rosacea, and you need to go to the hospital in time for examination to clarify the cause.
