What You'll Learn
Excessive nail polish use
Yellowish big toe nails can be caused by excessive nail polish use. This is especially true if you use red, yellow or orange nail polish. Although it may look unpleasant, this type of discolouration is usually harmless.
It is important to note that yellow toenails can sometimes be a sign of a more serious underlying health condition, such as diabetes. If you are concerned about the colour of your toenails, it is always best to consult a doctor. They will be able to determine if the discolouration is due to excessive nail polish use or if there is another cause.
If you suspect that your yellow toenails are due to excessive nail polish use, there are a few things you can do to prevent and treat this. Firstly, try to reduce the amount of nail polish you use. Give your nails a break between coats of polish to allow them to breathe. You can also try using a base coat before applying nail polish, as this can help to protect your nails from discolouration.
Additionally, make sure you are using a good-quality nail polish that is free from harsh chemicals. Some nail polishes can be very drying, which can contribute to discolouration. Choose a nail polish that is designed to be gentle on nails and avoid those that contain formaldehyde, toluene, or dibutyl phthalate.
Finally, if your nails are already discoloured, you can try using a nail whitening product. These products contain ingredients that help to brighten and restore the natural colour of your nails. You can find nail whitening products at most drugstores or beauty supply stores.

Fungal infections
Yellowish big toe nails can be a sign of a fungal infection. This is a common cause of yellow toenails, and it is more commonly seen in toenails than fingernails. The most common fungal infection is from the Trichophyton family. Fungal infections can cause thickening and deformity of the nail plate, which leads to the discolouration of the nail. This discolouration becomes worse with tight-fitting shoes or trauma to the nail plates and can be associated with athlete’s foot, as well.

Athlete's foot
Yellowish big toe nails can be caused by excessive nail polish use, fungal infections, diabetes, or weakened immune systems. One of the most common causes of yellow toenails is a fungal infection, which can be associated with athlete's foot. Athlete's foot is a common fungal infection that typically occurs between the toes, but it can also affect the toenails. It is caused by a fungus that thrives in warm, moist environments, such as sweaty shoes or socks.
The symptoms of athlete's foot include itching, burning, and stinging sensations between the toes, as well as redness, scaling, and cracking of the skin. In some cases, the infection can spread to the toenails, causing them to become discoloured, thickened, and deformed.
To prevent athlete's foot, it is important to keep your feet clean and dry, wear properly fitted shoes and socks, and avoid walking barefoot in public places, such as pools, locker rooms, and showers. It is also important to avoid sharing shoes or towels with others, as the fungus can be spread through direct contact.
If you suspect that you have athlete's foot, there are several over-the-counter antifungal treatments available, including creams, powders, and sprays. These treatments can help to clear the infection and prevent it from spreading. However, if the infection is severe or does not respond to treatment, it is important to see a doctor, as oral antifungal medications may be necessary.
In addition to treating the infection, it is important to take steps to prevent it from recurring. This includes practising good foot hygiene, such as washing your feet regularly and drying them thoroughly, especially between the toes. Wearing clean socks and changing them frequently can also help to keep your feet dry and prevent the fungus from growing.

Underlying health conditions, such as diabetes
Yellowish big toe nails can sometimes be a sign of an underlying health condition, such as diabetes. Nails are typically translucent, with the pinkish flesh underneath clearly visible. However, it is possible for the toenails to turn a shade of yellow, and this can happen for several different reasons.
Yellowing of the nail can indicate a fungal infection of the nail, which is more commonly seen in toenails than fingernails. The discolouration becomes worse with tight-fitting shoes or trauma to the nail plates and can be associated with athlete's foot. The most common fungal infection is from the Trichophyton family. Infection with fungus can cause thickening and deformity of the nail plate, which leads to the discolouration of the nail.
Another type of fungal infection is called proximal subungual onychomycosis. It looks like a whitish or yellowish patch that starts at the base of the toenail, near the cuticle. The infection is rare in healthy people. More often, it happens in people with weakened immune systems. It can also be a sign of HIV.
Excessive use of nail polish can also cause toenails to become discoloured. In particular, using red, yellow, or orange nail polish can cause the toenails to appear yellow. Although they may look unpleasant, yellow toenails resulting from too much nail polish are usually harmless.
