Hyperhidrosis: More Than Just Sweat
The Sweating Truth
•
- Excessive sweating can be embarrassing
- There is rarely a serious underlying medical issue
- It often develops during puberty
- Body odour is not primarily caused by sweat, but by bacteria digesting oils in sweat
Hyperhidrosis, a condition where the body secretes sweat in amounts greater than those required for regulating body temperature, is a common issue faced by many adolescents and young adults. A straightforward definition may seem accurate, but there is more to it than that. As our bodies undergo significant changes during puberty, it is not uncommon for people to sweat more and feel self-conscious about it.
One significant change during puberty is the activation of a subset of sweat glands, known as apocrine sweat glands. These glands become active in response to puberty hormones, leading to changes in the quantity and composition of sweat. The apocrine glands are responsible for producing a thicker, more oily sweat that is more prone to bacterial growth. This, in turn, contributes to body odour.
Interestingly, body odour is not primarily caused by sweat itself, but by the bacteria that digest the oils present in the sweat produced by apocrine glands. This means that even if someone is not sweating excessively, they can still have body odour. Antiperspirants, which are often used to control sweating, may not be sufficient in addressing body odour, as they can only reduce the amount of sweat, not the bacteria that break it down.
Medical Interventions
•
| Prescription-strength antiperspirants | May be sufficient to control symptoms |
| GP advice on other treatments | Range of options, including topical medications, Botox, oral medications, and iontophoresis |
| Iontophoresis | A procedure where a mild electrical current is applied to the area of skin with excessive sweating |
•
- Botulinum toxin (Botox) injections
- Oral medications
- Iontophoresis
•
According to the GP, other treatments may include topical medications, such as anticholinergic creams, or oral medications, such as beta-blockers or antidepressants. In some cases, a procedure called iontophoresis may be recommended. This involves the application of a mild electrical current to the area of skin with excessive sweating.
Support and Lifestyle Changes
•
- Encourage regular exercise to reduce sweat
- Cool showers and lighter clothing
- Reduce caffeine intake
•
Aside from medical interventions, there are several lifestyle changes that can help alleviate excessive sweating. Encouraging regular exercise, for example, can help reduce sweat production, as people with a lower exercise tolerance tend to sweat more with less effort. Cool showers and lighter, more ventilated clothing can also help reduce sweat. Reducing caffeine intake may also be beneficial, as stimulants can cause sweating.

Another suggestion is to limit alcohol consumption, as this can increase sweat production. Staying hydrated and drinking plenty of water can help regulate body temperature and reduce sweat.
Conclusion
•
Hyperhidrosis is a common issue faced by many adolescents and young adults. While it may seem embarrassing at times, it is often a temporary and normal part of growing up. With the right support and lifestyle changes, excessive sweating can be managed.
•
It is essential to remember that body odour is not primarily caused by sweat, but by bacteria digesting oils in sweat. Antiperspirants may not be sufficient in addressing body odour, and medical interventions may be necessary. Seeking medical advice is always a good idea, especially if excessive sweating persists.
