Excessive Sweating? Why It Happens and What to Do

We all know at least one person who seems to not sweat, even on extremely hot days. On the other hand, there are also cases of excessive sweating, where a simple handshake can turn into a nightmare.

If this is your case, it's natural that you may feel some embarrassment that can affect your self-esteem and social sphere.

To help this condition stop being a source of constant frustration, in this article we'll explain why it happens and, most importantly, how you can solve the problem once and for all.

 

Sweating excessively – the reasons

Sweating is a natural process, responsible for regulating our body temperature.

It is normal to experience increased sweating in certain situations, such as after exercise, when eating spicy foods, when the weather is hotter, among others.

Excessive sweating means that the sweat production process exceeds physiological needs, making soaked clothes and soggy hands a daily reality.

Generally, this condition is related to a case of Hyperhidrosis, in which the sweat glands are overstimulated, causing them to produce more sweat than normal.

Most often, in cases known as Primary Hyperhidrosis, it is not possible to determine the reason that triggers it, leading to the belief that it is a hereditary condition. Thus, it usually appears in childhood or adolescence, being more common in localized areas, such as armpits, palms, soles, scalp and back, for example.

There is another type of Hyperhidrosis – Secondary Hyperhidrosis. As this is a condition of generalized sweating all over the body, tends to appear in adulthood and is generally based on a health problem or a side effect of taking some drugs.

 

Other reasons

They exist other reasons that seem to lead to cases of excessive sweating, especially if associated with other symptoms, such as fever, chest pain, fatigue, rashes, dizziness, among others.

Thus, this condition may be related to:

  • Stress or anxiety;
  • Hypoglycemia;
  • Hyperthyroidism;
  • Heart attack or other heart problem;
  • Infections;
  • Diabetes.

 

How can you get rid of Excessive Sweating?

Although it is a physical condition, the truth is that Hyperhidrosis can considerably impact the psychological state of patients.

It is quite common for these conditions to lead to a decrease in overall quality of life, as they affect relationships, work and even the simplest tasks of daily life, such as writing a message on a cell phone (in the case of Hyperhidrosis in the hands).

In some cases, it can even lead to a need for isolation that can develop into more serious problems, such as depression, if the condition is left untreated.

In fact, one 2019 study reveals that people with Primary Hyperhidrosis have higher rates of depression, anxiety and attention deficit disorder when compared to the rest of the population.

Therefore, it is essential that you understand that there is treatment. In fact, several different methods are already available, such as Regular Toxin Injections or Thoracoscopic Sympathectomy.

In addition to these therapies, there are other very effective treatments that don't require medication or surgery, which you can learn more about below.

 

MiraDry: for excessive underarm sweating

Used for axillary hyperhidrosis, the MidraDry technique presents definitive results.

It is a method authorized by FDA (Food & Drug Administration), which is why it is completely safe and practically painless.

Through electromagnetic energy, the sweat glands in the region are dissolved, without compromising the natural perspiration process in the rest of the body.

It is a quick procedure (approximately one hour), requiring only one or two sessions.

What's more, you can resume your normal life after treatment, without any major restrictions.

 

PalmaDry: for excessive sweating on hands and feet

This is a procedure highly effective for hands and feet. In fact, the PalmaDry is the only one with high success rates for feet.

Furthermore, it is a non-invasive technique, so it does not require anesthesia or a recovery period.

As if that wasn't enough, can be done independently, at home, by purchasing your own device.

In this case, the results are progressive, requiring, on average, one session a day for 8 to 10 days, lasting around 15 minutes.

The treatment is performed by iontophoresis, where a low-intensity electric current is projected onto the skin of the hands or feet through the water in the equipment trays, “numbing” the sweat glands.

From then on, only spaced maintenance sessions are necessary, according to the doctor's recommendations.

 

Get ready to say goodbye to the embarrassments of Excessive Sweating

You already know the good news: it is possible to solve the problem.

However, first of all, it is important to consult a specialist doctor who, through an evaluation, will discover the cause of the problem and arrive at an accurate diagnosis.

From there, they'll be able to recommend the most appropriate procedure. While, in general, all procedures deliver highly satisfactory results, there's an ideal option for your specific case, capable of restoring the quality of life you've been searching for.

Allure Clinic has extensive experience with hyperhidrosis. Through treatments such as MiraDry and PalmaDry, the constraints you feel will soon be forgotten.
