Case and analysis

Case: After getting married, Ms. Wang quit her previous job and became a full-time housewife because her husband had a stable job and good pay. She just cooks and washes clothes every day, and spends most of her time in front of the computer, playing games, watching movies, and chatting on QQ. In particular, many of Miss Wang's friends make a living by using computers, and there are many people online on QQ. As long as Miss Wang's QQ avatar lights up, messages will flow in continuously and the QQ avatar will flash non-stop. It doesn't matter if they chat for a long time, but they often sit still for most of the day. After a long time, Miss Wang always felt uncomfortable in her anus, and sometimes it was extremely itchy, and the skin on her buttocks was scratched until it bled.

Analysis: Expert analysis: Sitting for a long time can easily lead to anal itching. Anal pruritus is more common in people who sit for a long time, which causes the temperature of the anus to rise. The buttocks are not easy to dissipate heat, which leads to increased sweat secretion, moisture and immersion, causing discomfort and itching. Patients with the initial onset of the disease often wash with hot water or apply topical drugs containing corticosteroids for a long time. Although this can temporarily relieve the itching, it can form a vicious cycle of itching - adverse stimulation - more itching over time, making local symptoms more severe. Eating spicy food can also cause anal itching. Poor hygiene habits, failure to clean the anus in time, and scratching and rubbing through pants can aggravate the itching.

Endocrine diseases: For example, the sugar content in the skin of diabetic patients increases, which stimulates the nerve endings and causes itching; the itching of skin cancer in hyperthyroidism may be related to excessive sweating, increased basal metabolic rate, and emotional tension.
