Everyone experiences sweaty palms occasionally — before a big presentation, during a tense meeting, or on a hot day. But for some people in Singapore, sweaty palms are a constant and uncontrollable problem that affects their confidence and daily life. If you find yourself wiping your hands frequently or avoiding handshakes, you might be dealing with a medical condition known as palmar hyperhidrosis.
Understanding what causes sweaty palms, and knowing when to see a specialist – a cardiothoracic surgeon — can help you take back control and find long-term relief.

What Are Sweaty Palms?
Sweaty palms, medically known as palmar hyperhidrosis, occur when the sweat glands in your hands become overactive. Sweat is a natural body function that helps regulate temperature, but in hyperhidrosis, the sympathetic nervous system — the part of your body that controls sweating — is overstimulated. This causes the palms to sweat excessively, even in cool weather or calm situations.
While it is normal to sweat in response to heat or stress, people with hyperhidrosis often find their hands dripping wet without any obvious trigger. This can make everyday activities like writing, holding objects, or using electronic devices frustrating and embarrassing.
What Causes Sweaty Palms?
There are several potential causes and contributing factors for sweaty palms, ranging from medical to genetic.
1. Overactive Sympathetic Nervous System
The most common cause is an overactive sympathetic nervous system — specifically, the nerves that run through the chest and control sweating in the hands. This overactivity leads to excessive sweating, even when the body doesn’t need to cool down.
2. Genetic Predisposition
Studies have shown that hyperhidrosis can run in families. If your parents or siblings also experience sweaty palms, you may have inherited the condition.
3. Emotional Triggers
Although not the root cause, emotions like stress, anxiety, or excitement can worsen sweating in people who already have hyperhidrosis.
4. Medical Conditions
Sometimes, sweaty palms can be secondary to other health issues such as thyroid disorders, diabetes, or infections. However, in most cases, the condition is primary hyperhidrosis, meaning it occurs on its own without an underlying illness.
5. Lifestyle And Environment
Singapore’s hot and humid climate can make symptoms more noticeable, but it does not directly cause the condition. People with hyperhidrosis often sweat excessively even in air-conditioned environments.
How Sweaty Palms Affect Daily Life
For many people in Singapore, sweaty palms are more than a physical inconvenience — they can have emotional and social consequences. Common challenges include:
- Difficulty shaking hands or holding objects
- Smudging documents while writing
- Trouble gripping steering wheels, sports equipment, or musical instruments
- Embarrassment during social interactions or professional meetings
- Damage to electronic devices from moisture
Over time, these issues can lead to anxiety and reduced self-esteem. Fortunately, there are effective treatments available — and in some cases, seeing a cardiothoracic surgeon may be the key to permanent relief.
Why You Should See A Cardiothoracic Surgeon
It might sound surprising, but cardiothoracic surgeons in Singapore play an important role in treating severe cases of sweaty palms. This is because they perform a specialised procedure known as Endoscopic Thoracic Sympathectomy (ETS) — the gold-standard surgical treatment for palmar hyperhidrosis.
What Is Endoscopic Thoracic Sympathectomy (ETS)?
ETS is a minimally invasive surgery that targets the overactive sympathetic nerves in the chest responsible for excessive hand sweating. During the procedure, the surgeon uses small incisions to insert a tiny camera and instruments to cut or clamp the affected nerves.
By interrupting these nerve signals, the palms stop sweating excessively — usually immediately after surgery.
Why A Cardiothoracic Surgeon?
Cardiothoracic surgeons specialise in operations involving the chest, heart, and lungs. They are uniquely trained to perform ETS safely and effectively, as the procedure requires navigating delicate structures within the chest cavity.
In Singapore, ETS is typically offered to patients who have not responded to non-surgical treatments like topical antiperspirants, oral medications, or Botox injections.
Benefits Of Seeing A Specialist Early
Consulting a cardiothoracic surgeon early allows you to:
- Understand your options — from conservative to surgical treatments
- Rule out secondary causes such as thyroid or metabolic conditions
- Receive tailored care based on your lifestyle and symptom severity
- Achieve long-term results, often with same-day recovery and minimal downtime
Most patients experience dry hands immediately after ETS, with a success rate of over 95% for palmar hyperhidrosis. Some may experience mild compensatory sweating (sweating in other parts of the body), but this is usually manageable and far less bothersome than sweaty palms.

Managing Sweaty Palms Before Surgery
If your condition is mild or you’re not ready for surgery, your doctor may recommend:
- Topical antiperspirants with aluminium chloride
- Iontophoresis, a therapy that uses mild electrical currents to block sweat glands
- Botox injections, which temporarily reduce sweating for several months
- Oral medications that decrease overall sweating
These treatments can help control symptoms temporarily, but they do not provide the lasting results that surgery offers for severe hyperhidrosis.
Frequently Asked Questions (FAQs)
Yes. ETS is considered a safe and well-established procedure when performed by an experienced cardiothoracic surgeon. It involves minimal incisions, a short hospital stay, and quick recovery. Most patients return to normal activities within a few days.
Sweating in the palms rarely returns after ETS. However, some people may develop compensatory sweating (increased sweating on the back, chest, or legs). This side effect is usually mild and manageable.
You should see a doctor if your palm sweating is persistent, interferes with daily life, or causes emotional distress. Early evaluation helps rule out underlying conditions and ensures you receive the right treatment options.
