If your condition is mild and not disturbing you, you may not require treatment. If your nail fungus is painful and has caused thickened nails, self-care steps and medications may help. But even if treatment is successful, nail fungus often comes reoccurs.

Nail fungus is equally called onychomycosis (on-ih-koh-my-KOH-sis). When fungus infects the areas between your toes and the skin of your feet, it’s called athlete’s foot (tinea pedis).

SYMPTOMS

You may have nail fungus if one or more of your nails are:

  • Thickened
  • Whitish to yellow-brown discoloration
  • Brittle, crumbly or ragged
  • Distorted in shape
  • A dark color, caused by debris building up under your nail
  • Smellling slightly foul

Nail fungus can affect fingernails, but it’s most common in toenails.

You may have to see a physician if self-care steps has not helped and the nail becomes increasingly discolored, thickened or deformed. Also see a doctor if you have diabetes and think you’re developing nail fungus.

CAUSES

Fungal nail infections are created by various fungal organisms (fungi). The most common cause is a type of fungus called dermatophyte. Yeast and molds also can cause nail infections.

Fungal nail infection can start in people at any age, but it’s more common in older adults. As the nail ages, it can become brittle and dry. The resulting cracks in the nails let fungi to enter. Other factors — such as lowered blood circulation to the feet and a weakened immune system — also may play a role.

Toenail fungal infection can begin from athlete’s foot (foot fungus), and it can spread from one nail to another. But it is uncommon to get an infection from someone else.

RISK FACTORS

Factors that can increase your risk of developing nail fungus include:

  • Being older, owing to reduced blood flow, more years of exposure to fungi and slower growing nails
  • Sweating heavily
  • Having a history of athlete’s foot
  • Walking barefoot in damp communal areas, such as swimming pools, gyms and shower rooms
  • Having a minor skin or nail injury or a skin condition, such as psoriasis
  • Having diabetes, circulation problems or a weakened immune system

 

COMPLICATIONS

A severe case of nail fungus can get very painful and may cause permanent damage to your nails. And it may result to other serious infections that spread beyond your feet if you have a suppressed immune system due to medication, diabetes or other conditions.

If you have diabetes, you may have lowered blood circulation and nerve supply in your feet. You’re also at greater risk of a bacterial skin infection (cellulitis). So any relatively minor injury to your feet — including a nail fungal infection — can result to a more serious complication. See your doctor if you have diabetes and feel you’re developing nail fungus.

PREVENTION

The following habits can help stop nail fungus or reinfections and athlete’s foot, which can lead to nail fungus:

  • Wash your hands and feet regularly. Wash your hands after touching an infected nail. Moisturize your nails after washing.
  • Trim nails straight across, smooth the edges with a file and file down thickened areas. Disinfect your nail clippers after each use.
  • Wear sweat-absorbing socks or change your socks throughout the day.
  • Choose shoes made of materials that breathe.
  • Discard old shoes or treat them with disinfectants or antifungal powders.
  • Wear footwear in pool areas and locker rooms.
  • Choose a nail salon that uses sterilized manicure tools for each customer.
  • Give up nail polish and artificial nails.

 

DIAGNOSIS

Your doctor will check your nails. He or she may also take some nail clippings or scrape debris from under your nail and send the sample to a lab to identify the particular  type of fungus causing the infection.

Other conditions, such as psoriasis, can mimic a fungal infection of the nail. Microorganisms such as yeast and bacteria also can infect nails. Knowing the cause of your infection helps know the best course of treatment.

TREATMENT

Fungal nail infections can be hard to treat. Talk with your doctor if self-care strategies and over-the-counter (nonprescription) products has not helped. Treatment depends on the severity of your condition and the type of fungus causing it. It can take months to see results. And even if your nail condition improves, repeat infections are common.

Medications

Your doctor may recommend antifungal drugs that you take orally or apply to the nail. In some situations, it helps to combine oral and topical antifungal therapies.

  • Oral antifungal drugs.These drugs are often the first choice since they clear the infection more quickly than do topical drugs. Options include terbinafine (Lamisil) and itraconazole (Sporanox). These drugs help a new nail grow free of infection, slowly replacing the infected part.

You typically take this type of drug for six to 12 weeks. But you will not see the end result of treatment until the nail grows back completely. It may take four months or longer to completely eliminate an infection. Treatment success rates with these drugs appear to be lower in adults over age 65.

Oral antifungal drugs may cause side effects ranging from skin rash to liver damage. You may require occasional blood tests to check on how you’re doing with these types of drugs. Doctors may not recommend them for people with liver disease or congestive heart failure or those taking certain medications.

  • Medicated nail polish.Your doctor may prescribe an antifungal nail polish called ciclopirox (Penlac). You paint it on your infected nails and surrounding skin once a day. After seven days, you wipe the piled-on layers clean with alcohol and begin fresh applications. You may require to use this type of nail polish daily for almost a year.
  • Medicated nail cream.Your doctor may also prescribe an antifungal cream, which you rub into your infected nails after soaking. These creams may work better if you first thin the nails. This aids the medication get through the hard nail surface to the underlying fungus.

To thin nails, you apply a nonprescription lotion containing urea. Or your doctor may thin the surface of the nail (debride) with a file or other tool.

Surgery

Your doctor may suggest temporary removal of the nail so that he or she can apply the antifungal drug directly to the infection under the nail.

Some fungal nail infections do not respond to medicines. Your doctor might suggest permanent nail removal if the infection is severe or extremely painful.
