Most people are familiar with Botox as a Hollywood staple to treat wrinkles. Injections of botulinum toxin type A, a neurotoxin, under wrinkles effectively smooth them out temporarily. This procedure leaves patients looking years younger than before. However, scientists are finding that Botox treatment is not exclusive to wrinkles. It can actually help people with excessive sweating, or primary hyperhidrosis.



How Sweating Works

The human body is a complex system of both voluntary and involuntary responses to stimuli. Involuntary responses, including breathing and digestion, are controlled by the autonomic nervous system. When a person feels hot, the brain uses this temperature information to activate the sweat glands in the dermis, or skin. Some areas, such as the scalp, armpits and groin, have extra sweat glands because of the hair follicles nearby. As a result, these areas may have more sweat than others. People with primary hyperhidrosis sweat excessively, even if it is cool outside. Essentially, the nervous system is over-stimulating these sweat glands to activate constantly.


The truth about hyperhidrosis (Excessive sweating)



Botox’s Role

When cosmetic Botox treatment is used on wrinkles, it creates a slight paralysis of the area, effectively reducing wrinkles as skin cells relax. Injecting Botox into sweaty areas allow doctors to use the same paralysis theory. Nerves controlling the sweat glands’ responses are effectively numbed, stopping sweat activation almost immediately.

Doctors must work with patients to verify where excessive sweating originates. An injection plan is created from there. Because the body’s sweat glands are in the middle layer of the skin, injections are not deep or painful.


Treatment Areas

People suffering from primary hyperhidrosis typically have the same sweaty areas affecting their everyday activities. Excessive sweating occurs across the palms, feet and armpits. Patients complain of wet clothing, along with damp hands and feet. Botox must be injected into these areas for proper control. Patients may opt to have all areas treated at once, if excessive sweat is a problem in all sites, or just one or two areas. Each patient has a unique treatment plan, requiring a doctor’s expertise to make everyday comfortable.


Injection Frequency

Botox lasts for about a year. If patients notice that their sweating is increasing, a doctor’s visit is critical to start the process again. Because Botox is an animal-based bacteria, this neurotoxin slowly breaks down. As paralysis subsides, the sweat glands are at the mercy of the nervous system, supplying signals to excessively sweat again. Another Botox injection allows patients to achieve a sweat equilibrium again for comfortable daily activities.

To find out more about Botox for sweating, patients can visit their doctor or ask this certified botox expert for more information. Excessive sweating doesn’t need to be a daily struggle. Botox injections are commonly covered under medical insurance, if it is deemed a medical necessity by a doctor. Sweating helps the body stay cool, but it is not healthy to have so much sweat concentrated in one area. Aside from the uncomfortable factor, patients lose a lot of water and electrolytes. Patients will feel much better with controlled sweat glands.
