Onychoptosis: Causes, Treatment & When to See a Doctor

Onychoptosis (nail shedding) is separation of the nail plate from the nail bed. Usually temporary.

Common Triggers

• Trauma (stubbing, tight shoes)
• Fungal infection (onychomycosis)
• Psoriasis, lichen planus
• Drug reactions (chemo, retinoids, antibiotics)
• Thyroid disease, iron deficiency

Conservative Management

• Protect nail (bandage, avoid trauma).
• Keep clean, dry.
• Topical antibiotic if infection suspected.
• Oral antibiotics/antifungals if confirmed.
• Remove loose nail if painful/catching.

Prevention

• Trim nails straight across.
• Proper‑fit shoes.
• Avoid nail biting/picking.
• Moisturize nails/cuticles.

See a doctor if no improvement in weeks, signs of infection, or systemic symptoms.
