Excessive sweating or hyperhidrosis occurs in 1% to 2% of the population. These poor patients sweat even when the circumstances don’t call for it. Most cases of excessive sweating are harmless, however profuse sweating hyperhidrosis can result in skin maceration and secondary infections.
Excessive sweating in the hands, underarms, face, and feet
Excessive sweating all over the body or in a larger area of the body, more likely to cause sweating during sleep or be caused by excessive heating, medications or medical conditions such as:
Neurotoxins inhibit release of acetylcholine at the neuromuscular junction, preventing the hyperstimulation of eccrine sweat glands that leads to excessive sweating. They have a rapid onset of reduction in sweating and effects lasting for months.
Fractional microneedle radiofrequency uses insulated microneedles to spare the upper part of the skin and deliver radiofrequency energy precisely to the sweat glands deep in the skin, leading reduction in functional sweat glands. Some patients may require up to three procedures to achieve significant long-lasting sweat resolution, however many patients will start seeing improvement after one treatment.
Patients suffering from hyperhidrosis can sometimes be deprived of simple things like holding their loved ones’ hands, or having to struggle with embarrassment in social situations such as giving a speech or sweaty pit stains in their clothing. Dr Wan deeply empathizes with their suffering.
In Dr Wan’s view, it is important to first assess the patient holistically looking out for causes of hyperhidrosis in particular, especially when larger areas are involved. If no secondary cause is found for generalized hyperhidrosis, generally oral medications would be prescribed as it may be difficult to treat large areas with other therapeutic options.
For focal hyperhidrosis, patients often feel frustrated with non-invasive approaches that may be cumbersome or ineffective, and yet may be afraid to undertake the serious risks of invasive surgery that may end up ineffective in the end.
