What are sweaty hands?
Palms that sweat excessively may be part of a condition known as hyperhydrosis. This is where the body produces excessive saliva in one particular area. The excessive sweating of the palms can be triggered by stress, heat, or happen spontaneously. Sweaty hands can be extremely distressing for most people and can prevent hand shaking and touching. Often people with hyperhydrosis are afraid to shake hands or place their palms on any glass or shiny surface.
What can be done?
Luckily, the sweat glands are controlled by a neurotransmitter called acetylcholine. This is the same neurotransmitter involved in nerve-muscle junctions all over the body. Botulinum toxin (Botox Therapeutic) blocks acetylcholine release, relaxing muscles and preventing sweating in a small area around any injection site.
- Rule out a medical cause such as overactive thyroid, certain medications, drug detoxification, or extreme anxiety (usually the hyperhydrosis is not limited to one area).
- Powders and sprays containing Aluminum are partially useful for a limited time.
- Botulinum toxin injection (Botox) into the sweaty area can produce approximately six months of dryness.
- Surgical sympathectomy can be performed in Toronto, Ontario but poses surgical risk and requires the lungs to be deflated during the surgery.
