How to banish yellow, brittle fungal nails and get your toes ready for summer

The internet is awash with tips, tricks and hacks to fix minor medical problems. But how much of it is accurate and can be trusted? In an age of misinformation and social media ‘experts’, it is always better to ask someone who is in the know about your health woes.

Each week, Superintendent Pharmacist Claire Nevinson will answer our readers’ questions on everything from insomnia and indigestion to trapped wind and toilet troubles. This week, Claire tackles fungal toenails…

Q: My toenails are yellow and brittle and I think it might be a fungal nail infection. What is the best cure?

A: Fungal nail infections can be unpleasant and sometimes painful. They are a common problem that can affect any nail, but most often affect the toenails.

The infection is caused by the growth of fungal spores that make their way between the toenail and the skin underneath the nail bed.

Usually, it first appears on the edge of your nail, under the tip, as a white or yellow streak. This streak then gradually spreads down the side of your nail to the base. Eventually, your nail may become brittle, yellow or brown in colour.

It may even become thickened or distorted. The nail may also end up crumbling, splitting and separating from the skin, causing the skin to become swollen and painful.

It’s important to act quickly if you notice any of these symptoms. If you don't treat the infection, it may worsen and spread to other nails.

Who is at risk of fungal nail infections?

This infection is often seen in the elderly, people with a weakened immune system and those who have diabetes or poor circulation.

This type of infection is highly contagious and flourishes in warm, moist environments. It can be picked up by walking barefoot in places such as communal swimming pools, showers, gyms and changing rooms.

Not keeping your feet clean or drying between your toes properly, may also trigger infection.

How to a treat fungal nail infection
