Overview
Excessive sweating, also known as hyperhidrosis, occurs when the body sweats more than is necessary to regulate temperature. It can affect males of all ages and may be caused by physical issues, hormones, stress, lifestyle habits, or medications. According to studies, hyperhidrosis affects around 3% of the world's population, including Australians1. Seeking medical advice is important as recurrent sweating can sometimes indicate an underlying health condition.Consult an AHPRA-registered practitioner online, anytime

Causes excessive sweating in males
Males' excessive sweating is commonly caused by primary hyperhidrosis, worry or stress, hormonal changes, infections, diabetes, thyroid disorders, obesity, and medication side effects. Sweating can occur throughout the day or night, ranging from minor to severe. A doctor should evaluate persistent or inexplicable sweating.Common medical causes of excessive sweating in men
Excessive perspiration can occasionally be associated with underlying medical issues.- Primary hyperhidrosis: A frequent disorder in which sweat glands become hyperactive without an obvious medical explanation. It often affects the hands, feet, underarms, and face.
- Hyperthyroidism: An overactive thyroid can increase metabolism and body temperature. Men may also experience weight loss, palpitations, and tremors.
- Diabetes or low blood sugar: Changes in blood sugar might cause bouts of sweating. Sweating can occur unexpectedly, particularly during low blood sugar occurrences.
- Infections (including viral disease): Fever and other illnesses can cause excessive sweating, including night sweats. This normally improves as the illness passes.
- Obesity: Excess body weight may increase heat production and perspiration. Sweating might intensify during physical exertion or in warm temperatures.
- Medication side effects: Some medications may cause increased sweating.
Lifestyle and emotional triggers
Lifestyle and emotional factors might also cause males to sweat more.- Anxiety and stress: Stress-induced perspiration often affects the hands, face, and underarms. Persistent symptoms may warrant medical attention.
- Spicy meals: Spicy foods might briefly cause perspiration and flushing. This is frequently referred to as gustatory perspiration.
- Alcohol: Alcohol may dilate blood vessels and raise body temperature. Some guys report facial or nocturnal perspiration after drinking.
- Caffeine: Caffeine stimulates the neurological system and causes perspiration. Symptoms may intensify after drinking coffee or energy drinks.
- Intense physical exertion: Exercise naturally raises the body temperature and causes perspiration. Excessive sweating above usual levels may still require evaluation.
Night sweats in men: what could it mean?
Night sweats are periods of excessive sweating while asleep.- Hormone imbalance: Hormonal changes can influence body temperature regulation. This may cause sweating at night.
- Infections: Some illnesses might produce fever and excessive nocturnal sweating. Symptoms may accompany weariness or a cold.
- Anxiety: Stress and worry can lead to midnight sweating. Poor sleep and racing thoughts may also occur.
- Blood sugar fluctuations: Low blood sugar during sleep might cause perspiration. This is more prevalent among diabetics.
- Certain medications: Some medications may cause excessive perspiration at night. A doctor can help you analyse potential side effects.

When to speak to a doctor about excessive sweating

- Associated symptoms such as palpitations or weariness: Additional symptoms may indicate an underlying medical issue.
- Sweating is associated with medication changes: A doctor can check whether any drugs are contributing.
How is excessive sweating diagnosed?
Doctors often diagnose excessive sweating based on medical history and symptoms pattern. They may enquire about when sweating occurs, which regions are affected, and whether symptoms arise during sleep. Blood tests or other investigations may be scheduled to check for thyroid issues, diabetes, or infections. Referrals may also be supplied if additional evaluation is required.Can excessive sweating be managed?
Management depends on the cause and severity of symptoms.- Prescription medication (when clinically acceptable): Following an assessment, a doctor may suggest management with medications.
- Managing an underlying medical issue: Managing thyroid disorders, diabetes, and infections may help to minimise perspiration.
- Lifestyle modifications: Some people may benefit from reducing their alcohol, caffeine, and spicy food intake.
- Stress management strategies: Relaxation techniques and mental health support may help alleviate stress-induced perspiration.
