Yellow nails are a common cosmetic concern for many people. It can be unsightly and can make you feel self-conscious about the appearance of your hands and feet.

There are several reasons why nails turn yellow, and some of them may indicate an underlying health issue.

Causes of Yellow Nails

1. Fungal Infection

Fungal infections are the most common cause of yellow nails. The fungi responsible for causing yellow nail syndrome are the same ones that cause athlete’s foot and ringworm.

Fungi thrive in warm, moist environments, making the feet and toenails more susceptible to infection. However, fingernails can also be affected. Athletes, people who sweat heavily, and those with weak immune systems are at higher risk of developing a fungal nail infection.

2. Smoking and Tobacco Use

Smoking and tobacco use can cause yellowing of the nails. Nicotine and tar, two of the main components of tobacco smoke, can stain nails and skin, making them yellow or brownish in color.

This discoloration may be more pronounced on the fingers and nails of smokers. Smoking can also reduce blood flow to the nails, which can cause them to become brittle and prone to breaking.

3. Aging

As we age, our nails become more brittle and prone to discoloration. The natural aging process can cause nails to become yellow and dull-looking. This is due to the slowing down of our body’s natural nail growth and renewal process.

Nails can also become thicker and more brittle with age, making them more prone to breaking and chipping.

4. Medical Conditions

Yellow nails can also be a symptom of an underlying medical condition. Medical conditions like diabetes, chronic liver disease, lung disease, and psoriasis can all cause yellowing of the nails.

In these cases, the yellowness is often accompanied by other symptoms, such as thickening of the nails, changes in nail shape, and nail separation from the nail bed.

What to Do About Yellow Nails

If you are concerned about the appearance of your nails, it’s important to consult a healthcare professional to determine the underlying cause. Treatment for yellow nails will depend on the underlying cause of the discoloration.

Fungal Infections

For fungal infections, topical or oral antifungal medications are often recommended. The nail may need to be removed in severe cases to allow the antifungal medication to penetrate the nail bed.

It’s important to keep your feet or hands clean and dry to prevent the spread of the infection.

Smoking and Tobacco Use

The only way to prevent yellowing of the nails due to smoking and tobacco use is to quit smoking. Over time, the discoloration may fade, and the nails will return to their normal color.
