Hyperhidrosis

Hyperhidrosis is a condition characterized by excessive sweating that goes beyond what is needed to regulate body temperature. The sweating may occur even when the person is not hot or physically active and can interfere with daily activities and quality of life.

Hyperhidrosis most commonly affects specific areas of the body, such as the palms of the hands, soles of the feet, underarms, and face. In some cases, sweating may occur over large areas of the body. The condition can begin in childhood, adolescence, or adulthood.

There are two main types of hyperhidrosis. Primary hyperhidrosis has no identifiable medical cause and often affects specific body areas. Secondary hyperhidrosis is caused by an underlying medical condition or medication and usually results in more generalized sweating.

Symptoms

The main symptom of hyperhidrosis is noticeable and excessive sweating that occurs regularly.

Common symptoms include:

• Visible sweating that soaks through clothing

• Sweaty palms that make it difficult to hold objects

• Moist or slippery soles of the feet

• Frequent need to change clothes

• Skin irritation or softening due to constant moisture

Excessive sweating may occur on one or both sides of the body and often happens at least once a week in primary hyperhidrosis. The condition can cause emotional distress, embarrassment, and avoidance of social situations.

Causes

The causes of hyperhidrosis depend on whether the condition is primary or secondary.

Primary hyperhidrosis is thought to be caused by overactive sweat glands triggered by the nervous system. It is not related to heat, exercise, or emotional stress alone and often runs in families.

Secondary hyperhidrosis is caused by an underlying condition or external factor, such as:

• Diabetes

• Thyroid disorders

• Menopause

• Infections

• Neurological conditions

• Certain medications, including antidepressants and pain relievers

In secondary hyperhidrosis, sweating may occur during sleep and usually affects larger areas of the body.

Risk factors

Several factors may increase the likelihood of developing hyperhidrosis.

Risk factors include:

• Family history of excessive sweating

• Onset during childhood or adolescence

• Medical conditions such as diabetes or thyroid disease

• Hormonal changes

• Use of medications known to cause sweating

People with primary hyperhidrosis often have otherwise good health but experience persistent symptoms.

Complications

Although hyperhidrosis is not usually life-threatening, it can lead to physical and emotional complications.

Possible complications include:

• Skin infections due to prolonged moisture

• Fungal infections, especially on the feet

• Skin irritation or breakdown

• Emotional stress, anxiety, or depression

• Social and occupational difficulties

Severe sweating may significantly affect self-esteem and daily functioning.

Prevention

Hyperhidrosis cannot always be prevented, especially in primary cases. However, certain measures may help reduce symptoms and complications.

Helpful prevention strategies include:

• Wearing loose-fitting, breathable clothing

• Choosing moisture-wicking fabrics

• Using antiperspirants regularly

• Maintaining good skin hygiene

• Avoiding known triggers, such as spicy foods or caffeine

• Managing underlying medical conditions that contribute to sweating

Early recognition and appropriate treatment can help control excessive sweating and improve overall quality of life.
