Hyperhidrosis

What is Hyperhidrosis?

Hyperhidrosis is a condition that causes excessive sweating beyond what the body needs to regulate temperature. The sweating may occur even when the weather is cool or when there is no physical activity.

Sweat is an odourless fluid released by the eccrine glands (sweat glands) to help regulate body temperature and prevent overheating. These eccrine glands are present in the skin, and sweat moves through these glands through ducts to the skin surface. After sweat leaves the ducts, it changes from liquid to gas and evaporates from the skin to cool down the body. In hyperhidrosis, the sweat glands overwork and produce excess sweat.

Some cases of hyperhidrosis may occur due to an underlying medical problem, while the cause of some cases may be unknown. However, in many cases, symptoms can be managed effectively with appropriate treatment.

What are the Types of Hyperhidrosis?

Hyperhidrosis is broadly classified into two main types based on its cause and pattern of sweating:

Stages of Hyperhidrosis

Hyperhidrosis is not defined in stages clinically, but by severity. Grades 1 and 2 generally indicate mild to moderate hyperhidrosis, while Grades 3 and 4 indicate severe hyperhidrosis that may require medical treatment. An overview of these 4 grades of hyperhidrosis is given below:

How Common is Hyperhidrosis in India?

The majority of hyperhidrosis cases are of primary hyperhidrosis, which often develops in infancy or early adulthood. In India, the prevalence estimate for hyperhidrosis is around 2.6%. Out of this, around 52% of cases were due to hereditary conditions, according to this study. However, clinical studies and dermatology reports suggest that the condition is often underdiagnosed and undertreated.

Increased detection and treatment of hyperhidrosis have made it more well-known in recent years.

What are the Symptoms of Hyperhidrosis?

Hyperhidrosis symptoms depend on the seriousness of the condition and whether it is primary or secondary hyperhidrosis. Patients are often plagued by excessive sweating, which can disrupt daily activities and social situations.

Common early warning signs and severe stage symptoms of hyperhidrosis include:

Diseases Similar to Hyperhidrosis

Many conditions may be confused with hyperhidrosis. Although these conditions affect sweating, they differ in their causes, symptoms, and management. An overview of similar diseases to hyperhidrosis is given in the table below:

What Causes Hyperhidrosis?

Hyperhidrosis may develop due to several medical and non-medical factors, including:

What are the Complications of Hyperhidrosis?

If left unmanaged, hyperhidrosis can lead to several complications.

• Skin Infections: Constant moisture encourages bacterial and fungal growth.

• Athlete's Foot: Damp feet increase fungal infection risk.

• Skin Maceration: Prolonged moisture softens and damages skin.

• Contact Dermatitis: Frequent sweating may irritate the skin and cause rashes or inflammation.

• Body Odour: Bacterial breakdown of sweat can cause unpleasant odours.

• Reduced Confidence: Many people feel self-conscious about visible sweating.

• Social Anxiety: Fear of sweating may affect social interactions.

• Difficulty with Daily Activities: Sweaty hands may interfere with writing, gripping objects, or using electronic devices.

• Emotional Stress: Ongoing symptoms can affect mental well-being.

When Should I See My Healthcare Provider?

You should consult a healthcare provider immediately if you experience any of the following:

• Sweating That Interferes With Daily Activities: Excessive sweating affects work, school or routine tasks.

• Sudden Increase in Sweating: Symptoms worsen without an obvious cause.

• Night Sweats: Excessive sweating occurs during sleep.

• Skin Problems: Redness, irritation, rashes or recurrent skin infections develop.

• Dizziness or Weakness: Sweating is accompanied by light headedness, weakness or fainting.

• Chest Pain or Palpitations: Excessive sweating occurs along with chest discomfort or an irregular heartbeat.

• Emotional Distress: Symptoms cause anxiety, embarrassment or social withdrawal.

• Lack of Improvement: Symptoms persist despite lifestyle changes or over-the-counter treatments.

How is Hyperhidrosis Diagnosed?

Healthcare providers may use the following tests and assessments to diagnose hyperhidrosis:

• Medical History and Physical Examination: The healthcare provider evaluates symptom patterns, family history, and affected body areas.

• Blood Tests: Blood tests help identify conditions such as diabetes or thyroid disorders that may cause excessive sweating.

• Urine Tests: Urine tests may help identify metabolic or hormonal disorders.

• Iodine-Starch Test: A special iodine solution and starch powder identify areas producing excessive sweat.

• Thermoregulatory Sweat Test: This test measures the body's sweat response under controlled conditions.

Diagnostic Assessment Table

Note: Hyperhidrosis does not have a single laboratory value that confirms diagnosis. Diagnosis is based on symptoms, clinical assessment, and exclusion of underlying conditions.

How is Hyperhidrosis Managed or Treated?

Treatment of hyperhidrosis usually focuses on reducing sweat production and improving daily comfort through the following approaches:

Common Medicines Used to Treat Hyperhidrosis

Several medicines can help reduce excessive sweating. The treatment depends on the affected body area, symptom severity, and whether the condition is primary or secondary.

Common medicines used to manage or treat hyperhidrosis are listed below:

• Aluminium Chloride Hexahydrate (20%): This prescription-strength antiperspirant blocks sweat ducts and reduces sweat production. It is usually the first treatment recommended for mild to moderate hyperhidrosis.

• Glycopyrronium Wipes or Topical Glycopyrronium: These prescription medicated wipes help reduce sweating, especially in people with excessive underarm sweating.

• Oxybutynin: Oxybutynin is an oral anticholinergic medicine that reduces sweat gland activity. It may be recommended for people with widespread or severe hyperhidrosis.

• Glycopyrrolate: Glycopyrrolate blocks nerve signals to the sweat glands, helping to decrease sweating.

• Propantheline Bromide: This medicine helps reduce sweating by decreasing the activity of sweat glands and may be considered for selected patients.

• Botulinum Toxin Type A: Botulinum toxin injections block the nerve signals temporarily that stimulate sweat glands. It is commonly used for severe underarm, palm and soles sweating.

Note: Treatment should only be administered by trained healthcare professionals, as these medicines can cause certain temporary side effects.

Living with Hyperhidrosis in India: Daily Challenges and Patient Well-Being

Living with hyperhidrosis can affect work, education, social activities and emotional well-being. India’s hot and humid weather may make excessive sweating more difficult to manage. Appropriate clothing, prescribed treatment, and regular dermatology follow-ups can help reduce its impact.

Some critical challenges and care points faced by hyperhidrosis patients and family include:

What is the Prognosis of Hyperhidrosis?

Hyperhidrosis is usually a long-term condition, but it can be managed effectively. Primary hyperhidrosis generally does not disappear completely. However, many people achieve significant symptom control with treatment or surgery.

Secondary hyperhidrosis may improve when the original cause is treated. Although a permanent cure is not always attainable, many people are able to better regulate their symptoms and have a better quality of life.

How Can I Prevent Hyperhidrosis?

Primary hyperhidrosis cannot always be prevented, as genetic factors play a role in it. However, you may reduce the severity of the symptoms by:

• Maintaining a Healthy Weight: Excess weight may increase sweating.

• Selecting Breathable Fabrics: Select cotton and moisture-wicking fabrics.

• Avoiding Trigger Meals: Reduce spicy meals and coffee.

• Stress Management: Relaxation practices may help minimise flare-ups of symptoms.

• Good Hygiene: Regular bathing may decrease skin issues.

• Keeping Skin Dry: Dry affected areas thoroughly after every washing.

• Treating Underlying Illnesses: Manage diabetes, thyroid disorders and other linked illnesses.

• Staying Hydrated: Fluid intake is important for temperature regulation as well.

Hyperhidrosis Treatment Cost in India

The hyperhidrosis treatment cost in India depends on the seriousness of symptoms, treatment procedures, hospital facility, and location. Generally, conservative treatments are less expensive, while Botox injections or surgery procedures can increase overall treatment costs.

Note: These costs are approximate and may vary depending on the city, hospital, dermatologist's expertise, treatment plan, and the number of sessions required.

Does Health Insurance Cover Hyperhidrosis?

Yes, health insurance covers hyperhidrosis treatment in certain situations. Most plans cover medically necessary hospitalisation for hyperhidrosis surgery, procedures and treatment for conditions causing this condition. However, Botox injections may not be covered if medically necessary and not for cosmetic reasons.

Outpatient expenses, including specialist consultations, diagnostic tests, and medicines, may be covered with the OPD benefit. However, coverage may vary between insurers.

Besides, a waiting period of about 1 to 3 years may apply if hyperhidrosis is a pre-existing condition, which was diagnosed before policy purchase.

Always review policy terms carefully before purchasing a policy.

How Much Health Insurance Coverage is Needed for Hyperhidrosis Treatment?

The amount of health insurance needed for hyperhidrosis treatment depends on symptom severity, treatment type, and the city where treatment is received. For most individuals, health insurance coverage of ₹5 lakh may be sufficient to cover dermatologist consultations, diagnostic tests, hospitalisation, and medically necessary procedures if required.

In case the patient has chronic illnesses or is a senior citizen, they should consider a higher coverage amount of at least ₹10 lakh.

Treatment costs can vary significantly depending on the hospital and treatment approach. Comparing plans can help find suitable coverage for your healthcare needs.
