What is Excessive Sweating?

Excessive Sweating - hyperhidrosisExcessive sweating, also known as hyperhidrosis is a condition that can be severe enough to disrupt a person’s life. This can have an impact on the ability to exercise and can affect relationships and emotional wellbeing. This type of excessive sweating particularly involves the armpits but can occur on any part of the body. It is due to overactivity of the sweat glands and is not necessarily related to the temperature or your clothing or level of exertion. It becomes a problem when the sweat is visible especially under the arms, where wet patches can be seen on clothing.

Treatment

There are a few treatments available for excessive sweating and you may have tried some of these, as a few can be found over-the-counter without a script. There are topical preparations such as roll-ons and sprays and these are called antiperspirants and available at chemists or at supermarkets. The most potent topical therapy contains aluminium chloride 20% and this is also known as Driclor. Another option is called iontophoresis. This helps to decrease sweating in the treated areas. It is used mainly on the hands and feet and rarely can be configured to use in the axilla. Iontophoresis involves using a very small electric current equivalent to a battery to stop the production of sweat. The machines need to be hired or bought and they are used initially every day and then can be used on a weekly basis. Some people cannot use these such as pregnant woman and people with a pacemaker.

Botulinum toxin: This treatment is very effective and is now covered under the PBS in Australia for axillary hyperhidrosis. It is very effective with noticeable effects starting after 2 days and a full effect within a week. The treatment lasts around 7-9 months.

Oral medication: There are some tablets that can be taken to decrease sweating. However, in practice, the side-effects of these often outweigh the benefits.

Self Care Tips

Excessive sweating can have an immense impact on a person’s life. If standard over-the-counter products do not control sweating, then it is best to see a dermatologist or other health care professional to assess the nature of the excessive sweating and exclude other causes such as certain medical conditions that can lead to excessive sweating. If these have been excluded then there are options to help with this.
