An itchy armpit indicates the itchy sensation one experiences in the underarm region. It can occur due to various reasons such as skin irritation, infections, allergic reactions, or underlying skin conditions.

The underarm is very prone to itching and rashes and the intensity ranges from mild to severe. Although it can be temporary, it is better not to ignore it.

Causes of itchy armpits

Heat and sweat

The hot and humid climate makes you shed more sweat than usual and a moist environment is perfect for bacteria and fungi to grow and multiply. Armpit itching because of sweat is very common. Candida or Candidiasis, a type of fungal infection, occurs frequently in the armpit due to its moist environment.

Dermatitis

 Any type of dermatitis can lead to an itchy armpit.

Atopic dermatitis

It is a form of eczema and is characterised by dry skin, itching, eczematous lesions, etc.¹

Seborrheic dermatitis

It is a chronic inflammatory disorder that occurs mainly in the scalp, face and body folds. It occurs due to the presence of unsaturated fatty acids on the skin surface.²

Contact dermatitis

Contact dermatitis can occur when the skin surface comes into contact with a certain substance like deodorants, soaps, personal care products, etc. that triggers an allergic reaction leading to itchiness.

Armpit folliculitis

This is a bacterial infection caused by Staphylococcus aureus leading to pus-filled red bumps or pustules in the armpit. Irritation from shaving and waxing can cause discomfort and itchiness.³

Poor hygiene

Inadequate cleaning of the axillary region (armpit) can lead to the accumulation of sweat, dirt, etc. causing irritation and itching.

Signs and symptoms of itchy armpits

• Redness
• Swelling
• Uncomfortable sensation with itching
• Persistent scratching can lead to a rash or small bumps

Management and treatment for itchy armpits

Medical treatment- when the itching persists for a prolonged time and the symptoms are aggravating, you may need to consult a healthcare professional for proper diagnosis and treatment.

Antihistamines are prescribed to treat allergic reactions, and Fluticasone skin cream to treat skin conditions like eczema, contact dermatitis, psoriasis, etc.⁴

Mupirocin treats skin conditions caused by bacterial infections, but this drug comes with warnings. All the mentioned medicines should be taken after proper consultation with your doctor.

Apart from medical treatment, you can manage an itchy armpit by practising good hygiene, avoiding skin irritants that trigger an allergic reaction, and regularly drying and moisturising the skin.
