Nails do more than look good; they can tell you a lot about your health. Changes in your nails might signal issues like nutrition problems or infections. Learning about nail disorders can help you spot health concerns early and keep your nails healthy. This article covers the five most common nail disorders, their causes, symptoms, and how to treat them.
1. Onychomycosis: The Fungal Nail Disorder
What is Onychomycosis?
Onychomycosis is a nail disorder caused by a fungal infection. It usually affects toenails more than fingernails. This condition is common, especially in adults over 40, athletes, and people with weaker immune systems.
Symptoms to Watch For
- Thickened nails
- Yellow or brown discoloration
- Brittle, crumbly texture
- Distorted nail shape
- Mild pain or discomfort
Causes of This Nail Disorder
Fungi grow well in warm, damp places. Sweaty shoes, swimming pools, and shared showers are common sources. Other risks include diabetes, poor blood flow, and small nail injuries.
Treatment Options
- Topical antifungal creams and nail lacquers: Effective for mild infections.
- Oral antifungal medications: Required for severe or persistent cases.
- Laser therapy: An advanced treatment option for stubborn infections.
Keeping your nails dry and clean, and not sharing nail tools, can lower your risk of getting this nail disorder.
2. Paronychia: The Nail Fold Infection Disorder
What is Paronychia?
Paronychia is a nail disorder that affects the skin around the nail. It can come on suddenly or last a long time, and is often caused by bacteria or fungi.
Symptoms to Look Out For
- Redness and swelling around the nail
- Painful tender area near the cuticle
- Pus formation in acute cases
- Nail deformities in chronic paronychia
Causes of This Nail Disorder
- Biting or picking at nails
- Frequent exposure to water or harsh chemicals
- Minor injuries to the nail fold
Treatment
- Warm soaks for mild cases to reduce inflammation
- Topical or oral antibiotics for bacterial infection
- Antifungal medications, if a fungal cause is suspected
To prevent paronychia, keep your nails dry, avoid biting them, and follow good manicure habits.
3. Onycholysis: The Detachment Nail Disorder
Understanding Onycholysis
Onycholysis happens when the nail separates from the nail bed. It usually doesn’t hurt at first, but it can cause infection if not treated.
Symptoms
- White or yellowish separation of the nail
- Thickened nail edges
- Gradual nail lifting from the nail bed
- Occasional mild discomfort
Common Causes
- Trauma or repeated injury to the nails
- Fungal infections
- Skin conditions like psoriasis
- Reactions to certain medications
Treatment
- Keeping nails trimmed and clean
- Avoiding exposure to irritants
- Treating underlying causes such as infections or skin disorders
If you notice onycholysis, it’s a good idea to see a doctor to prevent further infection.
4. Nail Psoriasis: The Chronic Inflammatory Nail Disorder
What is Nail Psoriasis?
Nail psoriasis is a long-term nail disorder related to psoriasis, a skin condition that causes red, scaly patches. Around half of the people with psoriasis also have nail problems.
Key Symptoms
- Pitting (tiny dents) on the nail surface
- Discoloration ranging from yellow to brown
- Thickened or crumbling nails
- Separation of nail from nail bed in severe cases
Causes
Nail psoriasis happens when the immune system attacks the skin and nails by mistake. Genetics, stress, and things in your environment can make it worse.
Treatment Options
- Topical corticosteroids or vitamin D analogs
- Phototherapy for severe cases
- Systemic medications for widespread psoriasis affecting the nails
Taking care of your nails and protecting them from injury can help prevent nail psoriasis from getting worse.
5. Ingrown Nails: The Painful Nail Disorder
Understanding Ingrown Nails
Ingrown nails, or onychocryptosis, happen when the edge of the nail grows into the skin. This causes pain and swelling.
Symptoms
- Redness and swelling
- Painful pressure around the nail edges
- Infection with pus in severe cases
Causes
- Improper nail trimming
- Tight footwear
- Genetic predisposition
- Trauma to the nail
Treatment
- Soaking feet in warm water to relieve discomfort
- Lifting the nail and placing cotton or dental floss to guide growth
- Partial or full nail removal in severe cases
- Antibiotics if infection develops
You can help prevent ingrown nails by trimming your nails correctly and wearing shoes that fit well.
How to Maintain Healthy Nails and Prevent Nail Disorders
Healthy nails are a sign of good health. Some nail disorders can’t be avoided because of genetics or long-term health issues, but simple habits can lower your risk:
- Keep nails clean and dry.
- Avoid biting nails or picking cuticles.
- Wear gloves when using harsh chemicals.
- Trim nails straight across to prevent ingrown nails.
- Moisturize nails and cuticles regularly.
- Avoid sharing nail tools to prevent infections.
- Visit a dermatologist if you notice unusual changes in your nails.
Nail disorders are common, but learning about them can help you avoid problems and keep your nails healthy. Each disorder, from fungal infections to chronic conditions, has its own causes, symptoms, and treatments. Taking care of your nails, noticing changes, and seeing a doctor when needed are the best ways to manage nail disorders.
Your nails do more than look good; they can show signs of your health. Watching for changes can help you avoid problems and keep your nails strong and healthy.
