多汗
Overview
多汗症的特征是异常, 出汗过多，可能出现在手上, 腋窝和脚. 对于一些, 大量出汗集中在一个部位, 比如手, while others may experience increased sweating in a combination of areas.
多汗 is rare, affecting about 1 percent of the population. 然而, 对于受影响的人, the condition often interferes with their daily activities and can be rather embarrassing in social situations. Although the exact cause of this excessive sweating remains unknown, we do know that it is commonly controlled by the sympathetic nervous system, which normally responds strongly in situations of fear or stress. It is not understood why patients with hyperhidrosis appear to have constant increased activity of this system.
我们治疗多汗症的方法
UCSF offers effective, long-lasting treatments for hyperhidrosis. These include Botox injections and a minimally invasive surgery called endoscopic thoracic sympathectomy (ETS), which blocks the excessive nerve activity leading to severe sweating. Our surgeons are experienced at performing ETS, and it's highly successful for most patients.
迹象 & 症状
多汗症的特征是异常, profuse sweating that can affect one or a combination of the following:
- 手，叫掌多汗症
- 腋窝，称为腋窝多汗症
- 足部，称为足底多汗症
The excessive sweating often interferes with daily activities. 例如, 手掌多汗症患者有湿, moist hands that sometimes interfere with grasping objects. Those with axillary hyperhidrosis sweat profusely from their underarms causing them to stain their clothes shortly after they dress. 足底多汗, 脚部出汗过多, 把袜子和鞋子弄湿, 什么会导致脚臭.
Symptoms of hyperhidrosis often become noticeable during childhood and adolescence. In many cases sweating can be quite severe, affecting everyday life and causing social embarrassment. It is thought that the excessive sweating may be brought on by stress, emotions or exercise. 然而，它也可以自发发生.
诊断
多汗症是通过体格检查诊断的. 除了, your doctor will ask how long you have been experiencing excessive sweating, 哪些区域受到影响, how often it happens and other questions to get a sense of the extent of your condition.
治疗
Many patients with hyperhidrosis try topical medications or herbal remedies to ease their condition, 但这些只是暂时的或没有任何好处. 幸运的是，有有效的治疗方法.
医疗肉毒杆菌
UCSF dermatologists use botulinum toxin (Botox) injections to treat hyperhidrosis. The injections temporarily block a chemical in the body that stimulates the sweat glands, and will reduce sweating for about four to six months.
The treatment is relatively painless, and most patients do not need anesthesia. 十大赌博平台排行榜 can apply anesthetic cream or ice to the skin before the injections, if desired. 病人 typically resume their regular activities immediately after the treatment.
ETS手术
Surgical interruption of the sympathetic nerve chain offers proven, long-term results. These nerves primarily affect blood flow to the skin and the function of the sweat glands. Interrupting the sympathetic nerves in the chest results in dilation of the veins and arteries in the arm and hand as well as the complete blockage of sweating.
A minimally invasive procedure called endoscopic thoracic sympathectomy (ETS) was developed to treat hyperhidrosis. 使用很小的切口, the sympathetic chain is cut or clamped to eliminate the excessive sympathetic nerve activity. The ETS procedure may be done on an outpatient basis with quicker recovery and less scarring than open surgery. The procedure is highly effective in eliminating excessive sweating of the hands in more than 98 percent of patients. 此外，并发症的风险也很低. ETS also can be used in some patients with axillary hyperhidrosis, 或者腋窝出汗过多.
UCSF surgeons have significant experience in treating hyperhidrosis using ETS. We can perform ETS on both sides of the body during a single operation if needed. The operation requires general anesthesia, and two 5 millimeter incisions on each side. Most patients leave the hospital in less than 24 hours and recover completely within two weeks.
