Hyperhidrosis is excessive sweating that mainly affects the palms of the hands and feet, the armpits or the face. This excess sweat is caused by an overactivity of the sweat glands in those areas of the body that produce more sweat than is necessary to control the normal temperature of the body. This alteration usually begins in childhood or puberty and usually lasts a lifetime.

​

This, in many cases, can cause alteration of social life, even making it uncomfortable to shake hands to greet someone, or to raise an arm, because the clothes may be soaked in sweat.

What causes it?

In certain situations, these glands work excessively, producing a greater amount of sweat. This situation is called localized hyperhidrosis. When it basically affects the hands and feet, then it is known as Palmoplantar Hyperhidrosis (PPH). When it basically affects the axillary region, it is known as Axillary Hyperhidrosis (AH).

HA and PPH can alter the normal rhythm of life, dirty clothes, papers and objects that are held with the hands, damage footwear and above all make it difficult for the sufferer's social life due to their reluctance to shake hands or Use it as an emotional communication tool.

The cause of PPH is unknown, although sweat glands in these regions are known to function abnormally. The axon endings of these neurons directly stimulate the sweat-producing cells of the glands. If these neurons were to disappear, the sweat glands would stop producing sweat.

Treatments to combat it

Botulinum Toxin type A is used to reduce or eliminate excess sweating in patients with severe focal hyperhidrosis thanks to the chemical denervation it produces.

Areas where it is applied

The administration is done by injections in the area affected by hyperhidrosis. The exact dose and the number of injection points will be adjusted in each case, although the average dose would be 50 U* per armpit.

​

The onset of the anhidrotic effect is usually noted 5 days after treatment and the maximum response is achieved in less than 10 days. The average duration of effect is 4-6 months.
