The results seem almost miraculous. In over 95% of all cases, the patients hands are dry and warm right after surgery. Hyperhidrosis of the feet is eliminated in about 60% of the cases. Facial sweating is helped in about 65% to 75% of the cases. Rapid heart rate and palpitations are also reduced dramatically. (Sic!)

After the operation, some patients might experience some degree of sweating in other locations such as the thighs or back. Most patients say that they are not troubled by this extra perspiration and it is preferable to sweaty palms. In most cases, the condition improves over time.
