Onycholysis

Onycholysis is a nail disorder where the nail plate separates from the nail bed. It can happen to fingernails or toenails. This condition may cause discomfort, discoloration, and changes in the nail’s look.

There are many reasons for onycholysis, like fungal infections, trauma, and certain health issues.

It’s important to know the signs of nail separation to get the right treatment. This helps prevent more damage to the nails. By understanding the causes and treatments, people can manage onycholysis and keep their nails healthy.

What is Onycholysis?

Onycholysis is when the nail plate separates from the nail bed. This can make the nails look bad and affect their health. It happens for many reasons, like fungal infections, injuries, and some health issues.

Definition of Onycholysis

The onycholysis definition is when the nail plate detaches from the nail bed. It starts at the free edge and moves towards the cuticle. As it gets worse, the area might turn white, yellow, or green, depending on the cause.

Symptoms of Onycholysis

The main sign of onycholysis is nail lifting. The nail plate becomes loose and separates from the bed. This can let dirt and moisture in, causing more problems. Other signs include:

• Nail discoloration, which may appear white, yellow, or greenish
• Brittle or crumbly nails
• Thickening of the affected nails
• Pain or discomfort in the surrounding skin

Onycholysis can also lead to other nail changes, like nail discoloration, ridges, or pitting. The symptoms can range from mild to severe, needing quick medical help.

Types of Onycholysis

Onycholysis can happen in different ways, depending on where the nail separates. There are two main types: distal subungual onycholysis and proximal subungual onycholysis. Each has its own causes and signs.

Distal Subungual Onycholysis

Distal subungual onycholysis is the most common. It starts at the nail tip and moves towards the cuticle. This causes the nail to look white or yellowish because air or moisture gets trapped.

It can be caused by trauma, fungal infections, or exposure to irritants. Medical conditions like psoriasis and thyroid disorders can also lead to it.

Proximal Subungual Onycholysis

Proximal subungual onycholysis is less common. It starts at the nail base, near the cuticle, and moves towards the tip. This creates a visible gap between the nail and the skin.

This type can signal serious health issues like systemic infections or autoimmune disorders. Medications like chemotherapy drugs or certain antibiotics can also cause it.

Knowing the difference between these two types is key for proper diagnosis and treatment. Healthcare professionals can then focus on the right cause and develop a plan to fix the nail and prevent more problems.

Causes of Nail Separation

Several factors can cause onycholysis, a nail disease where the nail plate separates from the nail bed. Knowing the cause is key to finding the right treatment and preventing it from happening again. The main onycholysis causes include:

Fungal infection is a common reason for onycholysis. The fungus can invade the nail plate, causing it to separate from the nail bed. Dermatophytes, yeasts, and non-dermatophyte molds are the main culprits in fungal nail infections. Trauma to the nail, whether sudden or repeated, can also cause separation by damaging the nail plate or the nail bed underneath.

In some cases, onycholysis is a sign of an underlying health issue. For example, psoriasis can lead to nail changes, including onycholysis, nail pitting, and discoloration. Thyroid disorders, such as hyperthyroidism and hypothyroidism, can also affect nail health and cause separation. Reactive arthritis, an inflammatory condition triggered by an infection, can cause various nail changes, including onycholysis.

Fungal Infections and Onycholysis

Fungal nail infections, also known as onychomycosis, are a common cause of onycholysis. When fungi invade the nail plate, they can disrupt the attachment between the nail and the underlying nail bed. This leads to separation and detachment.

How Fungal Infections Lead to Nail Detachment

Fungal organisms, such as dermatophytes and candida, can penetrate the nail plate through small cracks or openings. As the infection progresses, the fungi release enzymes that break down the keratin in the nail plate. This weakens the structural integrity of the nail and causes it to lift away from the nail bed.

The detachment typically starts at the distal end of the nail and gradually spreads proximally. As the infection worsens, the nail may become thickened, discolored, and brittle. In some cases, debris may accumulate under the detached portion of the nail, further contributing to the separation.

Common Fungal Culprits

Several types of fungi can cause onychomycosis and subsequent onycholysis. The most common culprits include:

Identifying the specific type of fungus responsible for the nail infection is key for the right treatment. Prompt diagnosis and appropriate antifungal therapy can help prevent the progression of onycholysis and restore the health of the affected nails.

Trauma and Injury as a Cause of Onycholysis

Trauma to the nail can come from sudden acute injury or repeated nail damage. This can break the bond between the nail plate and the nail bed. This break can cause the nail to start lifting away from the skin underneath.

Acute Trauma

Acute nail injuries can happen suddenly, like a direct hit or a crushing force. These injuries can make the nail plate separate right away. Here are some examples of acute trauma that might cause onycholysis:

Repetitive Trauma

Repetitive trauma to the nails might not be as sudden as acute injuries. But, it can also cause onycholysis over time. This happens when the nail plate separates from the nail bed due to constant pressure or picking. Here are some common causes of repetitive nail damage:

• Wearing ill-fitting shoes that continuously rub against the toenails
• Excessive nail picking or manipulation
• Repeated exposure to irritating chemicals or moisture
• Engaging in activities that put prolonged pressure on the nails, such as long-distance running or rock climbing

Knowing how both acute and repetitive trauma can lead to onycholysis helps protect your nails. It also helps prevent nail separation.

Other Medical Conditions Associated with Onycholysis

Many medical conditions can lead to onycholysis. Psoriasis, an autoimmune skin disorder, can cause nails to separate from the nail bed. It often results in scaly patches on the skin.

Thyroid disorders like hyperthyroidism and hypothyroidism can also affect nails. They can disrupt nail growth, causing nails to detach. Here’s a table showing how common nail changes are in thyroid disorders:

Reactive arthritis, an inflammatory arthritis caused by bacterial infections, can also lead to onycholysis. It causes joint pain and inflammation, along with nail changes.

Some medications can cause onycholysis as a side effect. These include chemotherapy drugs, retinoids, and certain antibiotics. If you think a medication is causing your nail issue, talk to your doctor about other options.

Diagnosing Onycholysis

Getting a correct diagnosis for onycholysis is key. It helps find the cause and choose the right treatment. The process starts with a detailed nail examination by a doctor. Then, lab tests might be needed.

Physical Examination

The doctor will closely look at the nails during the exam. They search for signs like separation, color changes, and other issues. They might also ask about your health history, lifestyle, and recent injuries or illnesses. This first step helps figure out what to do next.

Laboratory Tests

More tests might be required to find the cause of onycholysis. Some common ones include:

Doctors use the results from the exam and lab tests to make a precise onycholysis diagnosis. They then create a treatment plan to fix the problem and help the nail grow back.

Treatment Options for Onycholysis

Dealing with onycholysis means fixing the cause of the nail separation. This could be a fungal infection, trauma, or another health issue. Once the cause is treated, the nail can start to grow back right.

For fungal infections, doctors often prescribe antifungal meds. These can be taken by mouth or applied directly to the nail. For mild cases, creams or lacquers are used. But for severe infections, stronger drugs are needed.

Treating the Underlying Cause

It’s also important to tackle any factors that led to onycholysis. Keeping nails dry and avoiding harsh chemicals helps. Wearing shoes that fit right can also prevent nail damage. Treating health issues like psoriasis or thyroid problems can stop onycholysis from coming back.

Topical and Oral Medications

Topical treatments include creams or lacquers applied to the nail. They fight fungal infections and help the nail grow. For serious cases, oral drugs like terbinafine or itraconazole might be used.

Surgical Intervention

Sometimes, surgery is needed to treat onycholysis. Nail avulsion removes the affected nail. This lets doctors apply antifungal meds directly to the nail bed. It helps grow a new, healthy nail.

Prevention of Onycholysis

Keeping your nails healthy is key to avoiding nail separation. This helps prevent the discomfort and unsightly look of onycholysis. By taking care of your nails and avoiding trauma, you can lower your risk.

Good nail hygiene is vital. Keep your nails clean and dry, trim them often, and avoid harsh chemicals and too much water. Wear gloves when washing hands or doing water tasks to protect your nails.

To prevent onycholysis, avoid nail trauma. Here are some tips:

It’s also important to manage any health issues that might lead to nail separation. If you have a fungal infection, psoriasis, or thyroid disorder, work with your doctor to control these conditions. Early action can stop onycholysis from getting worse.

If you see signs of nail separation, like lifting, discoloration, or changes in nail texture, get help fast. Your doctor can find the cause and suggest treatments to stop further damage and help your nails grow back healthy.

When to Seek Medical Attention for Nail Separation

If you’re dealing with persistent nail separation or severe symptoms from onycholysis, knowing when to get medical attention is key. Mild cases might heal by themselves. But, some situations need a visit to a dermatologist or healthcare provider.

Think about getting medical help for onycholysis if:

A dermatologist can figure out why your nail separation is happening. They might do a physical check, ask for lab tests, or take nail clippings. This helps find out if a fungal infection or something else is causing your onycholysis.

Getting medical attention on time can stop more damage to your nails and help you heal faster. Don’t wait to see a professional if your nail separation doesn’t get better or if you have any severe symptoms that bother your daily life.
