Causes Of Hyperhidrosis (Excessive Sweating) And How To Treat It    

Everyone sweats. Sweating is a way for the human body to cool itself down when it gets overheated from exercising or being in a warm environment. It can also be an indication of being anxious or nervous. However, if you always find yourself sweating a lot, even when you are not active or in a hot place, you might have hyperhidrosis.

Hyperhidrosis is a medical condition characterised by excessive sweating. The sweating may affect just one particular area or the entire body. While not life-threatening, excessive sweating can be uncomfortable and cause embarrassment or mental trauma.

In this article, we have laid down some of the most common causes of hyperhidrosis and the most effective treatments you can try to get rid of excessive sweating.

Causes of Hyperhidrosis

1. Pregnancy

A woman’s pregnancy is usually a time when her hormone levels fluctuate wildly, thereby causing her to experience hyperhidrosis. This is especially true in her first and third trimesters as well as postpartum. In addition, pregnancy often causes a woman’s blood flow throughout her body to increase, thereby causing her to feel warmer and more likely to sweat.

2. Menopausal 

Like pregnancy, a woman’s hormone levels greatly fluctuate during menopause. As her body prepares for menopause, her estrogen levels particularly increase and decrease significantly. This hormonal fluctuation then results in the sudden onset of a warm feeling accompanied by sweating. Menopausal-induced hyperhidrosis typically occurs in the transitional period before menopause, called “perimenopausal.”

3. Diabetes 

Diabetes is a medical condition that affects the way a person’s body utilises blood sugar or glucose. It can cause low levels of blood sugar, which then triggers a flight or fight response that prompts the release of specific hormones like adrenaline, which causes excessive sweating. Low blood sugar for an extended period of time can lead to neuropathy, a condition of damaged nerves. Neuropathy that impacts the sweat glands often causes too much or too little sweating.

4. Obesity 

Hyperhidrosis can also be caused by obesity or by having a BMI of 30 or more. There are a couple of reasons why obese people tend to sweat excessively. For one, they usually need to exert more effort to perform everyday activities and are more likely to feel overheated. Because they have a low surface area in relation to their weight, their body also needs to work harder to cool themselves down, thereby resulting in more sweating.

Treatment for Hyperhidrosis

1. miraDry® Treatment 

There are several types of treatments available to eliminate hyperhidrosis, but the most effective of them is the miraDry® treatment, which is one of the treatments carried out by Tokyo Garden. MiraDry for hyperhidrosis in Singapore is a very popular treatment because it has a proven efficacy of up to 82%. In practice, the efficacy actually ranges from 50% to over 90%, depending on the individual.

miraDry® is basically a microwave device intended to treat underarm hyperhidrosis by making use of microwaves to knock down sweat and odour glands, thereby leaving the skin intact. However, it is important to note that this non-surgical treatment does not result in a bone-dry sensation. The majority of patients will still feel some sweat around their armpits. Nonetheless, it is an excellent treatment whose total satisfaction rate is up to 90%.


There are many possible causes of hyperhidrosis. Although this condition is not life-threatening, it can cause you to feel uncomfortable, embarrassed, and even lose confidence in yourself. Fortunately, there are several treatments available for minimising or eliminating excessive sweating. If you particularly sweat a lot from your armpits, Tokyo Garden’s miraDry® treatment is the solution you need!
