If wet armpits are a regular concern, you can have a botulinum toxin injection. It is used to treat hyperhidrosis, a clinical case of increased perspiration. The toxin blocks the nerve impulses leading to the sweat glands, so sweat is not secreted. The effect of the injection lasts for 6-12 months.
When no antiperspirants help, you need to find out the reason with your doctor. If your diagnosis is hyperhidrosis, the sweat glands can be treated with a laser: this permanently stops their functioning.
Since sweating is involved in heat regulation and removing unnecessary substances from the body, the laser is only applied to increased sweating areas detected by the Minor’s starch iodine test.
Heavy sweating can be a symptom of serious diseases such as heart failure and diabetes. If you noticed that you have started to sweat more than usual, consult a doctor.
