Excessive Sweating
Hyperhidrosis is the medical term for excessive sweating. Sweating is one of the most important ways in which the body loses heat, however, people with hyperhidrosis, produce sweat in amounts far greater than needed to control their temperature.
The Treatment
For those wanting an effective solution to their underarm sweating, injections of botulinum toxin (type A) has been shown to be a very effective treatment.
The Science
The toxin blocks messages from the nerves to the sweat glands. So even if the nerves are telling the glands to release sweat, they don't respond.
The Results
Effects start within the first week after treatment and last for an average of seven months before further injections are required. Side effects are rarely troublesome.
