Sweating is a natural way for your body to regulate its temperature. But when sweating becomes excessive, frequent and difficult to control, it can start to affect more than just your comfort.
Hyperhidrosis is a condition that causes excessive sweating, often in specific areas of the body.
If you’ve already read our guide on Hyperhidrosis vs Normal Summer Sweating, you may recognise some of the signs. But what actually causes excessive underarm sweating, and what can you do about it?
What Causes Underarm Hyperhidrosis?
Hyperhidrosis occurs when the sweat glands become overactive, producing more sweat than the body actually needs to regulate its temperature.
For some people, excessive sweating can happen even when they’re not exercising or exposed to hot weather. It can also be triggered by everyday situations such as stress, nervousness or social interaction.
In many cases, underarm hyperhidrosis isn’t linked to an underlying health problem. However, if you experience a sudden or significant change in your sweating, it’s always worth discussing it with a healthcare professional.
What Are the Signs of Underarm Hyperhidrosis?
Everyone experiences sweaty underarms from time to time. Hyperhidrosis tends to be more persistent and can interfere with everyday life.
Some common signs include:
- Excessive underarm sweating even when you’re not particularly hot
- Sweat marks appearing quickly on clothing
- Having to change tops during the day
- Avoiding certain colours or materials because of visible sweat
- Feeling self-conscious about sweating in social or professional situations
- Finding that regular deodorants or antiperspirants aren’t enough
For some people, the biggest impact isn’t the sweating itself, but the constant awareness of it.
How Can Underarm Hyperhidrosis Be Treated?
There are several approaches to managing excessive sweating, depending on the individual and the severity of the condition.
For people experiencing persistent underarm sweating, Botox treatment can be an effective option.
Botox works by temporarily blocking the nerve signals responsible for activating the sweat glands in the treated area. This reduces the amount of sweat produced by the underarms without affecting the body’s ability to regulate its temperature elsewhere.
What Does the Treatment Involve?
Underarm hyperhidrosis treatment with Botox involves a series of small injections directly into the affected area.
The procedure is relatively quick, and there is minimal downtime, meaning most people can return to their normal routine afterwards.
Results develop over the days following treatment, with a noticeable reduction in underarm sweating.
