Overview

Sweating is the body’s natural way of controlling temperature while keeping you cool. However, stress, anxiety, and menopause are known causes of increased sweating, unexpected changes in sweating patterns may also be associated with infections, medications, hormonal changes, low blood sugar, or other medical conditions.

This article discusses the potential causes for sudden excessive sweating in women, how to manage symptoms, management options, and when to seek medical help.

What is excessive sweating?

Hyperhidrosis is characterised by excessive sweating that goes beyond what the body naturally needs to regulate its temperature. It can affect one or more parts of the body, such as the hands, feet, underarms, or face.

Common causes of sudden excessive sweating in women

Possible cause	Examples
Hormonal changes	Menopause, perimenopause, pregnancy
Infections	Influenza, COVID-19, tuberculosis, and other infections cause fever
Thyroid disorders	Overactive thyroid (hyperthyroidism)
Low blood sugar	Particularly in people with diabetes using insulin or certain medicines
Medications	Some antidepressants, pain medicines, hormone treatments, and medicines that affect blood sugar
Stress and anxiety	Panic attacks, emotional stress
Primary hyperhidrosis	Excessive sweating without an identifiable medical cause
Other medical conditions	Certain neurological disorders, heart conditions, or, rarely, some cancers

Symptoms that may occur alongside excessive sweating

Excessive sweating may be accompanied by other symptoms, such as:

• Night sweats
• Flushing
• Palpitations
• Dizziness
• Trembling or shaking
• Fever
• Unexplained weight loss
• Fatigue
• Shortness of breath

If you experience severe, worsening, or life-threatening symptoms, such as acute chest pain or severe difficulty breathing, call 000 immediately or attend your nearest Emergency Department (ED).

What can you do at home?

Simple self-care practices can reduce sweating and increase comfort.

Stay hydrated: Excessive sweating increases fluid loss. Drink water throughout the day to lower the risk of dehydration.

Wear lightweight, breathable clothes: Choose loose-fitting garments and breathable fabrics like cotton or moisture-wicking materials to keep cool.

Keep the environment cool: Use fans, air conditioning, or open windows whenever possible, particularly in hot weather or at night.

Use a clinical-strength antiperspirant if appropriate: Clinical-strength antiperspirants can reduce sweating by blocking sweat glands. Follow the product directions closely and seek medical attention if you experience skin irritation.

Manage stress with relaxation techniques: Stress and worry can cause sweating in certain people. Useful approaches include:

• Deep breathing exercises
• Mindfulness or meditation
• Yoga
• Engaging in regular physical activity
• Counselling if stress persists

Avoiding recognised triggers: Some people report increased perspiration after consuming:

• Spicy meals
• Excess caffeine
• Alcohol
• Extremely hot beverages

Maintain a symptom journal: Recording when you sweat, how long it lasts, accompanying symptoms, medications, and potential triggers may help your doctor identify the cause.

Clinical management options	When it may be considered

• Sweating is associated with unexplained weight loss.
• You develop a fever.
• You experience palpitations or dizziness.

When is it an emergency?

• Difficulty breathing
• Fainting or losing consciousness
• Confusion
• Symptoms of a severe allergic response include swelling of the face or neck.

How is excessive sweating diagnosed?

To identify the cause of excessive sweating, your doctor will enquire about your symptoms, medical history, medicines, and potential triggers. They can additionally conduct a physical examination and recommend further investigations if necessary.

This may include:
