Pustules are considered to be related to acne pustules, impetigo, pustular psoriasis and other diseases, and their recurrent attacks are considered to be related to factors such as low immunity, endocrine disorders, repeated scratching and diet, with the specific causes varying from disease to disease. 1. The recurrence of acne pustules is considered to be related to dietary factors such as liking greasy food, spicy and stimulating food, or endocrine disorders such as staying up late or studying or working under pressure, or repeated scratching of the local rashes, etc., which can lead to recurrence of acne due to the stimulation of sebaceous glands to secrete more sebum or the combination of other bacterial infections with localized breakage. 2. The recurrence of impetigo is mostly related to age and low immunity, etc. Because this disease is a bacterial infection, it is easy to lead to the recurrence of this disease for younger or older people and malnourished patients or patients with malignant tumors and other chronic wasting diseases. 3. The recurrence of pustular psoriasis is related to factors such as mental stress, fatigue, combining with other infections, using stimulating drugs and so on. Due to the increased mental stress or fatigue will to a certain extent damage the patient’s immune function, so it will increase the recurrence of psoriasis, and for the combination of HIV, streptococcal infection, the risk of its onset is significantly higher than that of the general population. For patients with pustules, it is important to pay attention to the above reasons that can easily lead to recurrence of the disease, and avoid them while treating them. If the pustules continue to remain unrelieved, it is recommended that the patients go to the hospital as soon as possible to have a clear cause of the disease and then actively treat it.
