Hyperhidrosis/Excessive Sweating

What Is Hyperhidrosis/Excessive Sweating?

Hyperhidrosis is the medical term for excessive sweating, especially in the armpits, palms, and other areas that form a crease and produce sweat. This is a serious problem that can lead to complications such as fungal infections, skin conditions and emotional distress for sufferers.


Symptoms of hyperhidrosis are mainly excessive sweating in various areas of the body, but most commonly the armpits, face, groin, and palms of the hands and soles of the feet. It is for this reason that the condition is simply referred to as excessive sweating. The key difference between hyperhidrosis and normal sweating is that the condition causes the sufferer to sweat for no immediate reason; they do not have to be in a hot environment, or in a stressful situation.


There are two main types of hyperhidrosis – primary and secondary.

Primary Hyperhidrosis

There is no clearly understood cause for primary hyperhidrosis, though it is thought to lie with a problem with the sympathetic nervous system. This system controls the natural functions of the body that occur subconsciously, such as the movement of food and waste within the digestive system. This system also controls body temperature and signals the eccrine gland to produce sweat in order to cool the body down. With hyperhidrosis sufferers, the brain sends a signal to these glands to produce sweat for no reason.

Some studies suggest primary hyperhidrosis may be passed down through families as a genetic mutation.

Secondary Hyperhidrosis

Secondary hyperhidrosis is brought on more suddenly than primary hyperhidrosis, and tends to affect the whole body. Secondary hyperhidrosis has a cause, and this could be a number of different triggers. Pregnancy, obesity, and taking certain medications can cause excessive sweating, and unlike primary hyperhidrosis, can easily be pinpointed and treated.


Excessive sweating does not normally cause any major health risks, although it does put the sufferer at a higher risk of fungal infections and some skin conditions. The primary downside of hyperhidrosis is the emotional effect that abnormal sweating can have in one's life. Some people that suffer from hyperhidrosis may feel anxious and/or depressed due to the social impact it can have, such as shaking hands, and visible sweat stains on clothing.

Side Effects of Botox and Aluminium Deodorants

A common treatment for excessive sweating is Botox injections, also known as Botulinum toxin type A. In the case of underarm sweating, the Botox that is injected acts to block chemical signals sent from the brain to the sweat glands, resulting in the gland not producing sweat. Aside from injections only lasting a number of months, requiring continual repeat injections, there are some serious side effects that must be noted. Due to Botox causing muscle weakness, the most serious side effects can be trouble breathing, swallowing and speaking, which can be fatal if not attended to immediately. Immediate side effects also include loss of vision, dizziness and muscle weakness.

Excessive sweating sufferers may be prescribed high strength deodorants/antiperspirants that contain a high level of aluminium chloride hexahydrate. Although the process of using these products is simple, the long-term side effects of aluminium are serious. Breast cancer, kidney problems, bone disorders and Alzheimer's disease are all side effects that have been associated with the neurotoxin Aluminium.
