The appearance of boils on the vulva may be caused by improper diet, personal hygiene, endocrine disorders or gynecological inflammation. Vulvar boils are formed due to the blockage of hair follicles or sweat glands in the pubic area, the details are as follows: 1. Improper diet: boils on the vulva can be stimulated by prolonged intake of spicy and irritating food or by drinking and smoking. 2. Personal hygiene: boils may develop due to excessive secretion of sebaceous glands and blockage of hair follicles as a result of the infiltration of sweat, urine and feces on the vulva. 3. Endocrine disorders: when the hormone secretion disorders in the body lead to metabolic disorders in the pores of the pubic area, the metabolic substances are retained in the hair follicles and cannot be discharged, thus forming boils. 4. Gynecological inflammation: common in vulvitis and vaginitis. Inflammatory secretions irritate the skin of the vulva, leading to vulvar infections. If you have the above symptoms and feel uncomfortable, it is recommended that you go to the hospital in time, under the guidance of a physician, do not use your own medication, so as not to delay the condition.
