Excessive sweating treatment alternatives

Excessive sweating can be treated in several ways.

1. Specialized antiperspirant

A doctor might suggest an aluminum chloride-containing antiperspirant. It is frequently used to treat mild symptoms of hyperhidrosis and is stronger than those purchased without a prescription.

2. Iontophoresis

While one is submerged in water, a gadget that generates low-level electrical currents is used in this treatment. The currents are frequently applied to your armpits, hands, and feet to temporarily block your sweat glands.

3. Anticholinergic medications

Anticholinergic medications can reduce widespread perspiration. These medications, including glycopyrrolate (Robinul), stop acetylcholine from functioning. Your body creates acetylcholine, which helps to activate your sweat glands.

These medications have a two-week working period and can have adverse effects, including dizziness and constipation.

4. Botox (botulinum toxin)

Severe hyperhidrosis may be treated with Botox injections. They block the neurons that activate your sweat glands. Usually, it takes a few injections for this treatment to start working.

5. Surgery

Surgery could be able to treat your disease if you simply perspire in your armpits. In one surgery, the sweat glands in the armpits are removed. An endoscopic thoracic sympathectomy is another choice. To do this, you must cut the nerves which transmit signals to your sweat glands.
