Palmar hyperhidrosis, a condition characterized by excessive sweating of the palms, can be a frustrating and embarrassing problem for those who suffer from it. Can you imagine having sweaty palms, greeting someone, or holding your phone or even a pen?
Although harmless, several patients who struggle with palmar hyperhidrosis often prefer getting timely treatment to manage the symptoms for a better outcome in the long run and not to make social situations awkward. Contact Dr Arvind Kumar to get the expert advice.
This guide will explore all you need about palmar hyperhidoptions available for you.
Palmar hyperhidrosis is a condition that causes excessive sweating of the hands. This is a physiologic condition caused by an overactive sympathetic nervous system. It occurs in about 1% of the population and may be hereditary. Hyperhidrosis can be very embarrassing and debilitating. Learn more about its causes, symptoms, and treatment options.
Palmar hyperhidrosis, or excessive sweating, is caused by overactivity of the eccrine sweat glands present in specific spots including the palms and the soles of the feet. These sweat glands are regulated by discrete nerve cells that use acetylcholine as the neurotransmitter. When the levels of acetylcholine in the bloodstream flare up, the eccrine glands get overstimulated and produce excess sweat.
Other body parts like the chest contain a distinct group of sweat glands called apocrine sweat glands. These glands are regulated by nerve cells that use norepinephrine for signal transduction and remain unaffected by the levels of acetylcholine in your body. This is the reason palmar hyperhidrosis affects only certain body parts.
Apart from being hereditary in certain cases, palmar hyperhidrosis is also caused by various other factors including:
Emotions like stress, anxiety, and nervousness often lead to increased levels of acetylcholine in your bloodstream. This can trigger excessive sweating in the palms, soles of your feet, and sometimes the face. It is, however, an acute effect and resolves as soon as you feel emotionally stable and the acetylcholine levels return to normal.
Vasovagal syncope is a condition of emotional distress caused by specific triggers like the sight of blood, fear of heights, and others. It leads to other accompanying symptoms like a spike in the pulse, dizziness, and cold sweat. The sweating dissipates once the distress is resolved.
Hormonal imbalances or any endocrine disorders can affect the levels of acetylcholine in your body. In cases where the condition increases the amount of this neurotransmitter, you experience excessive sweating. This cause can lead to chronic palmar hyperhidrosis unless the underlying cause is treated or managed.
Certain medical conditions can affect the sensitivity of your nerves, and the levels of acetylcholine, or cause other emotional or endocrinal distress. This can lead to excess sweat and can be chronic or acute.
It could be caused by certain neurological conditions that cause nerve injury or progressively damage the nerve cells like:
Cancerous or non-cancerous tumors including the following can also feature palmar hyperhidrosis as a symptom:
Infections that affect the hypothalamus, the temperature-regulating center of the body, can also lead to palmar hyperhidrosis. In general, fever causes the acetylcholine levels in the body to drop. But certain infections like the following have the opposite effect:
Based on the type and dosage, abuse of drugs or alcohol can cause palmar hyperhidrosis. It could be in the form of a withdrawal or from consumption. Some substances that are known to cause excessive sweating include:
Now that you clearly understand the potential causes, let us shift our focus to the symptoms. The most common symptom of this condition is excessive sweating in the palms.
Besides that, a few additional symptoms include:
The patients have sweaty hands, often cold and may even be dripping with sweat. It has significant social and psychological impact, forcing the patients to hide their hands in their pockets or under their arms and avoid social contact. The students face serious problems in examinations as their copies get wet. There may be problems in the job also. Overall, it decreases the self-confidence of the patients, who are constantly under pressure to hide this problem.
When meeting clients, colleagues and other professionals, patients with Palmar hyperhidrosis face extraordinarily difficult tasks of how to make their hands dry. Often, the hand shake is avoided. When writing on paper, they need to keep a napkin underneath their hand to protect whatever they are writing on.
Palmar hyperhidrosis can be acute or chronic and caused by different factors. For a more precise diagnosis and treatment, the condition is classified into the following types:
While palmar hyperhidrosis in itself does not cause any medical emergency, it takes a toll on your self-confidence and affects daily activities. Also, it could be triggered by an underlying condition that may need medical attention. In any case, it is best to see a doctor if you experience the symptoms.
The doctor would ask you about the symptoms including when they began, if they are triggered in specific situations, if you have any hormonal imbalances, and others. This is to try and ascertain the cause of the condition and decide on the appropriate treatment path.
To check the severity of the condition, the doctor may perform the following tests:
Paper test: Here, they would place a sheet of paper on your palms for a specific period to determine the amount of sweat released.
Scratch iodine test: Here, the doctor will apply iodine solution and let it dry. Then they sprinkle starch solution on it. In areas of excess sweat, the solution will turn dark blue.
Fortunately, various non-surgical treatment options are available for individuals with palmar hyperhidrosis. The main objective of these treatments is to manage and alleviate the symptoms so the patient can have an improved quality of life.
Some of the most effective treatment options include:
One of the most common and direct ways of treating this condition is by applying over-the-counter or prescription-strength antiperspirants that contain aluminum chloride. These ointments function by blocking the sweat glands temporarily, thereby reducing sweating.
The next effective treatment for palmar hyperhidrosis is Iontophoresis, which is a non-invasive medical procedure. In this, the patient is asked to dip their palms in a shallow tray of water. A low-intensity electrical impulse is passed through the water, effectively reducing sweat production in the palms. The patients have to undergo frequent sessions for sustained results.
Although not quite common, the use of Botox injections is effective in treating this condition. The injected botox blocks the signals that stimulate sweat production. The results from this treatment are usually temporary and can last up to 6 months.
In some cases, patients are prescribed anticholinergic drugs to reduce the sweating in their palms. However, these medications aren’t for everyone since they have many side effects. Hence, assessing the compatibility of the prescribed drugs with the patient’s overall well-being is a must.
This surgical procedure involves cutting or clamping the sympathetic nerves responsible for sweat production in the palms. It has pretty effective results, but the list of consequences and potential risks associated with the treatment makes it unfit for several patients.
There is no medical cure for this condition. Although numerous medications are available in the market, they at best help only the mildest forms of the disease. Removal of controlling nerves (ganglion) in the neck can cure Palmar Hyperhidrosis immediately. It had not gained much popularity till recently because of the need for Thoracotomy to be able to do removal of ganglion (cervical sympathectomy).
Sweaty palms and feet could be caused by palmar hyperhidrosis. This is highly probable if any of your close relatives have this condition, or it could be the result of an emotional trigger or an underlying disorder. To be sure, it is better to consult with your doctor. Once you know the cause, you can address the problem. If you get sweaty palms due to emotional distress, meditation or counseling could help. If it is hereditary or caused by an underlying condition, you may need medical guidance to manage it better.
You could inherit palmar hyperhidrosis which causes sweaty palms. Sweaty palms, or cold sweat, is also a sign of emotional distress or trigger. Hormonal imbalances, infections, and certain medical conditions also include sweaty palms as a symptom. While having sweaty palms is not a medical emergency in itself, it could be an indication of a medical condition that could need medical attention. So if you experience this condition frequently, consult with your doctor.
Palmar hyperhidrosis can lead to various consequences affecting one’s quality of life. If you are embarrassed about being in social situations due to the condition and want to overcome the challenges, the list of available treatments in this guide is worth considering.
