What causes of Excessive Sweating & Treatments for Hyperhidrosis

What causes Excessive Sweating ? And how is Hyperhydrosis treated using injectables?

If you’re prone to heavy excessive sweating and problem perspiration throughout the year, you may dread warmer temperatures. So what causes excessive sweating (hyperhidrosis) and how can it be treated? Read more about the increasingly popular sweat-reducing injections for treating under-arm sweat, sweaty palms and hands and other areas where you experience problem perspiration.

Excessive sweating & perspiration? Hyperhidrosis is a condition that leaves many individuals uncomfortable or self-conscious.

Even the coolest Melbournians can get a little hot and sweaty from time to time, especially when:

  • Exercising
  • Playing Sports
  • Visiting hot and humid climates
  • Temperatures exceed 25 degrees C
  • Feeling nervous or anxious before an interview, during a first date or other important meeting
  • During intimacy

But what if you sweat profusely all the time?

You may have HYPERHIDROSIS, a condition involving chronic sweating or heavy perspiration.


The condition of excessive sweating is called hyperhidrosis. Fortunately, it can be treated with an injected solution to reduce over-active sweat gland functions.

What is hyperhidrosis?

  • Sweating is a normal bodily function that occurs in order for physical temperature regulation.
  • Normal levels of perspiration helps to cool you down when your body becomes too hot.
  • Sweating is necessary and normal, but excessive, chronic sweating or problem perspiration may be associated with hyperhidrosis.
  • Sometimes an underlying health condition is to blame for excess sweating, but often, excessive perspiration occurs in normally healthy individuals, who’ve had the problem since their adolescent years (or longer).

Contrary to the concept of saunas, sweat isn’t the primary source of excreting toxins – that’s more likely to occur through urine and other methods of excretion rather than sweat for most people.

Perspiring becomes ABOVE what might be considered ‘normal perspiration levels’  when your body is sweating at times when your body does NOT need cooling for being too hot.

Where on the body do people perspire/sweat most?

People with hyperhidrosis usually find that the excessive sweating occurs over several locations on their bodies.

Common areas impacted by hyperhidrosis excessive sweating include:

  • Feet
  • Palms of the hands
  • Underarms
  • Face or head
  • Chest
  • Back

Why do people have excessive perspiration? What causes Hyperhidrosis?

First, what is perspiration (‘sweat’)?

  • Sweat consists primarily of H2O (water) and electrolytes (sodium & chloride being the primary two).
  • Other elements found in perspiration include amino acids, lactate, urea, potassium, bicarbonate and calcium.

What causes excessive perspiration?  How do I know if I have hyperhidrosis?

The nerves in our body cause us to sweat by sending a message to the brain that the body needs to sweat in order to cool down.  But when these nerves go into overdrive, they over-send these messages to the sweat glands.

This leads to excessive sweating (hyperhydrosis).

You often know if you have hyperhidrosis due to the nature of perspiration.

In people with this condition, perspiration tends to be:

  • chronic no matter what the weather or situation
  • excessive
  • impacting your confidence or clothing choices
  • disruptive to sports, sleep or social life

The precise causes of having hyperhidrosis when you’re otherwise healthy are not fully known yet, but research has shown that:

  • There is a genetic link (i.e. if you sweat excessively, you probably have a relative who has the same experience)
  • It can be caused by an underlying medical condition such as endocrine imbalances or hormonal changes, gout or diabetes, but quite often occurs in healthy individuals
  • It can be a side effect of certain medications or substance use
  • It can occur during the time of menopause for some women


Athletes, Sports, Intimacy and Excessive Sweating

Excess sweating can also be an issue during sports as well as moments of intimacy.

  • If you’re an athlete with hyperhidrosis, you might even sweat to a level that your hands and body become slippery and impact your sports performance.
  • Your facial sweat may also get into your eyes and impact your ability to focus on the bat, ball, hockey stick or hand signals.
  • Or if you’re in the midst of an intimate moment, you may be embarrassed by sweat dripping off your body.
  • Or you may find you awake each morning to a sweat-soaked bed.

What is the treatment for hyperhidrosis or excessive sweating or perspiration?

  • Some individuals find they can control their sweating using strong antiperspirants or other primarily-topical solutions.
  • Others learn to live with the condition and simply refuse to wear light coloured clothing, which they may find limiting but achievable.

However, this can be an embarrassing problem that affects sufferers regardless of the season and usually has life-style impacts.

It can be comforting to know that treatment is available from our Coco Ruby Skin & Anti-Ageing team – particularly our top Injection Clinicians – Dr Tina Purdon, and Sandra Wallace Senior Injecting RN.



Hyperhidrosis Solutions & Medical Treatments – Injections to armpit area, hands or feet.

Muscle relaxant injections and other injectables, are some of the most popular and most successful forms of non-surgical treatments for those people who haven’t responded well to antiperspirant or other temporary remedies.

  • The anti-excessive sweating injections work by disabling over-active sweat glands in the affected regions.
  • They can have a positive effect to help reduce or to stop excessive sweating, at least temporarily – but they can be repeated as they do wear off after 9 months to about one year for most patients.
  • This time frame can vary, but many patients report getting at least 6 to 9 months of reduced sweating from their initial a treatment, with top-ups or re-treatment required between 6 to 10 months on average (varies).


Duration of Effectiveness of Injections for Excessive Sweating (Hyperhydrosis)

Treatment results can last for up to 9 or 12 months, although everyone reacts to the treatments differently.

  • Hyperhydrosis injectables may work for less time for some individuals than for others.
  • Treatments can be repeated as required.
  • Each injectables procedure usually takes under 15 to 30 minutes per area (under arms, for example, can take less than 5 to 10 minutes per armpit area).
  • The treatment has minimal downtime and is not uncomfortable for most people – because the injection needles are so thin (micro-fine injections)
  • The injections are over very quickly and they are short in duration and depth; but if you’re worried about being uncomfortable, your Clinician can provide you with medical-grade pre-treatment numbing cream

Results After Injections to Reduce or Stop Excessive Sweating

It may take up to a week to 10 days for the full effects of Hyperhydrosis Injection Treatments to be felt and seen, as the sweat glands will need to adjust to the treatment that has been injected.

After treatment, you may be a little sore for a few days in the treated areas. But within a short period of time, you will be able to wear all of those items of clothing you feared wearing due to revealing sweat marks or perspiration stains.
