Excessive sweating, also known as diaphoresis, can be more than just an inconvenience. This common physiological response often signals underlying health issues or environmental factors that need attention. While sweating is a normal bodily function, diaphoresis goes beyond typical perspiration, potentially causing discomfort and social anxiety for those affected.
This comprehensive guide delves into the complexities of diaphoresis, exploring its various causes and treatment options. Readers will gain insights into when excessive sweating might indicate a more serious condition and learn about effective management strategies. From medical interventions to lifestyle adjustments, this article aims to equip individuals with the knowledge to address diaphoresis and improve their quality of life.
What is Diaphoresis?
Diaphoresis, also known as secondary hyperhidrosis, refers to excessive and abnormal sweating that is not related to physical exertion or warm temperatures. It tends to affect the entire body and is usually caused by an underlying medical condition or as a side effect of certain medications.
The term “diaphoresis” originates from the Greek word “diaphorein,” which means “to carry through.” Diaphoresis is pronounced as “dia-fuh-ree-sis.”
Symptoms
The main symptom of diaphoresis is profuse sweating that occurs without an obvious trigger, such as heat or exercise. The sweating is often visible, soaking through clothing or dripping off the body. Night sweats, which can soak through bedsheets, are also a common occurrence in people with diaphoresis.
Other symptoms may include:
- Sweating that starts in adulthood
- Generalized sweating affecting large areas of the body
- Sweating that occurs both during the day and at night

Difference from Normal Sweating
Sweating is a normal bodily function that helps regulate body temperature. When the body temperature rises, the nervous system signals the sweat glands to release salty fluid, which cools the skin surface as it evaporates, reducing core body temperature.
In contrast, diaphoresis involves excessive and abnormal sweating that is not related to the body’s need to cool down. The sweating occurs in the absence of typical external triggers and is often a symptom of an underlying health issue or a side effect of medication.
While some people may naturally sweat more than others due to factors such as genetics or the number of sweat glands they have, diaphoresis is characterized by sweating that is far more pronounced and occurs without a clear cause.
Common Causes of Diaphoresis
Diaphoresis, or excessive sweating, can have various underlying causes. These causes can be broadly categorized into medical conditions, medications, hormonal changes, and substance withdrawal.
Medical Conditions
Certain medical conditions can trigger diaphoresis. Hyperthyroidism, an overactive thyroid gland, speeds up metabolism, leading to increased body temperature and sweating. Diabetes can cause hypoglycemia, or low blood sugar, which triggers the body’s fight-or-flight response and profuse sweating. Heart attacks and anaphylaxis, a severe allergic reaction, can also cause excessive sweating along with other symptoms like chest pain, difficulty breathing, and hives. Some cancers, such as leukemia, lymphoma, liver cancer, and bone cancer, may also lead to diaphoresis.
Medications
Prescription and over-the-counter medications can have side effects that include excessive sweating. Diabetes drugs such as insulin, hormone therapy medications, fever reducers like acetaminophen and aspirin, pain medications, antibiotics, antivirals, and chemotherapy drugs can all cause diaphoresis.

Hormonal Changes
Hormonal fluctuations, especially in women, can lead to excessive sweating. Menopause is one of the most common causes of diaphoresis in women due to fluctuating estrogen levels. These hormonal changes send false signals to the brain, triggering hot flashes and night sweats. Pregnancy can also cause diaphoresis due to hormonal shifts, increased metabolism, and weight gain.
Substance Withdrawal
When a person with alcohol use disorder or substance use disorder tries to quit, they may experience withdrawal symptoms, including diaphoresis. Other withdrawal symptoms can include agitation, anxiety, nausea, racing heartbeat, tremors, and seizures. Some of these symptoms may be life-threatening, so it’s crucial to work with a healthcare provider when attempting to quit using a substance.
Diagnosis and When to See a Doctor
Diagnosing diaphoresis involves a comprehensive evaluation of the patient’s medical history, physical examination, and diagnostic tests. Healthcare providers aim to identify the underlying cause of excessive sweating and determine the most appropriate treatment approach.
The medical history intake is a crucial step in the diagnostic process. Patients should provide detailed information about the onset, duration, and severity of their sweating, as well as any associated symptoms or triggers. It is important to disclose any pre-existing medical conditions, medications, and family history of hyperhidrosis or other relevant disorders. Clinicians may inquire about the impact of excessive sweating on daily activities and quality of life.
During the physical examination, healthcare providers assess the distribution and severity of sweating. They may use visual scales or the iodine-starch test to quantify the extent of palmar sweat. The examination also focuses on identifying any signs of underlying medical conditions that could be causing secondary hyperhidrosis.
Diagnostic tests may be ordered to rule out potential causes of secondary hyperhidrosis. These tests may include blood work to evaluate thyroid function, blood glucose levels, and other relevant markers. Urinary catecholamine levels may be measured to screen for pheochromocytoma, while a purified protein derivative (PPD) test can be performed to assess for tuberculosis. Imaging studies, such as chest radiography, may be used to investigate neoplastic causes of hyperhidrosis.
Certain red flag symptoms warrant prompt medical attention and further evaluation. These include:
- Sweating that starts in adulthood
- Generalized sweating affecting large areas of the body
- Sweating that occurs both during the day and at night
- Asymmetric or localized hyperhidrosis, which may suggest an underlying neurologic disorder
If excessive sweating is accompanied by other concerning symptoms, such as chest pain, shortness of breath, or unexplained weight loss, it is essential to seek immediate medical care to rule out potentially serious conditions.
Treatment Options for Diaphoresis
Treatment for diaphoresis aims to manage excessive sweating and improve quality of life. The approach may involve medications, lifestyle changes, and alternative therapies, often used in combination for optimal results.
Medications
Prescription antiperspirants containing aluminum chloride can temporarily block sweat pores, reducing the amount of sweat reaching the skin. Applying these products to dry skin before bed and washing them off in the morning can help manage mild diaphoresis. Prescription creams and wipes containing glycopyrrolate may ease symptoms on the face, head, hands, feet, and underarms.
Oral medications, such as anticholinergics, beta-blockers, and benzodiazepines, can also be used to treat diaphoresis. Anticholinergics like glycopyrrolate and oxybutynin work by blocking the chemical messenger acetylcholine from stimulating sweat glands. Beta-blockers and benzodiazepines are best for patients with episodic or event-driven hyperhidrosis, as they help manage the physical manifestations of anxiety.

Lifestyle Changes
Making certain lifestyle adjustments can help manage diaphoresis. These include:
- Using antiperspirants containing 6% to 20% aluminum chloride
- Wearing shoes and socks made of natural, breathable materials
- Changing socks or hose one to two times a day and keeping feet dry
- Using shoe insoles and foot powder to absorb sweat
- Wearing clothing suitable for the activity and made of natural, breathable fabrics
Alternative Therapies
Some alternative therapies may help manage diaphoresis, although more research is needed to confirm their effectiveness. These include:
- Herbal remedies such as sage tea or tablets, chamomile, valerian root, and St. John’s Wort
- Acupuncture
- Biofeedback
- Hypnosis
- Relaxation techniques
A combination of treatments tailored to the individual’s needs is often the most effective approach to managing diaphoresis. Working closely with a healthcare provider can help determine the best course of action and achieve optimal results.
