Sweaty Palms (Palmar Hyperhidrosis)
Sweaty palms, medically known as palmar hyperhidrosis, is a condition where the sweat glands in the hands produce excessive amounts of sweat, even when it’s not needed for cooling the body. This condition is not life-threatening but can cause discomfort and social anxiety, affecting daily life and interactions.
The main symptom of sweaty palms is excessive and persistent sweating on the palms. Additional features may include:
- Sweat dripping from the hands during regular activities
- Cold, clammy palms, even in cool environments
- Difficulty holding objects, writing, or using tools due to wetness
- Embarrassment or discomfort during handshakes or social interactions
What are the symptoms?
What are the causes and risk factors?
Sweaty palms are caused by overactive sweat glands, often triggered by the nervous system. The exact cause is unknown, but factors include:
Primary hyperhidrosis
A condition with no underlying medical cause, typically starting in childhood or adolescence.
Secondary hyperhidrosis
Excessive sweating caused by an underlying condition, such as thyroid disorders, diabetes, anxiety or stress, and certain medications.
Genetics
Family history of hyperhidrosis increases the risk.
Age
Primary hyperhidrosis often begins in teens or young adults.
What are the complications from the condition?
While not harmful, sweaty palms can lead to complications, such as:
- Social or emotional impact: Feelings of embarrassment, anxiety, or isolation
- Difficulty performing tasks: Writing, gripping objects, or using touchscreens may be challenging
- Skin infections: Persistent moisture can increase the risk of bacterial or fungal infections
- Reduced quality of life: Interference with work, social activities, or sports
How is it diagnosed?
Diagnosis involves evaluating symptoms and ruling out underlying conditions. Common diagnostic steps include:
- Medical history and physical exam: To assess the extent and triggers of sweating
- Lab tests: Blood or urine tests to check for conditions like thyroid problems or diabetes.
How is it treated?
Treatment depends on the severity of symptoms. Options include:
- Lifestyle changes: Avoiding triggers like spicy foods, caffeine, or stress.
- Antiperspirants: Prescription-strength antiperspirants containing aluminium chloride can block sweat glands.
- Medications
- Anticholinergic drugs to reduce sweat production.
- Beta-blockers or anti-anxiety medications for stress-related sweating.
- Botox injections: Temporarily block nerve signals to sweat glands, providing relief for several months.
- Iontophoresis: A treatment where hands are submerged in water, and a mild electrical current reduces sweating.
- Surgery
- Endoscopic thoracic sympathectomy (ETS): A minimally invasive procedure to cut or clamp nerves that control sweating.
