What Else Can Fingernails Tell A Dermatologist About Your Health
Nails say a lot about your health. Your dermatologist can look for changes in the nail texture, brittleness, lunula , overall shape and color of your nails.
Seeing changes in the shape and color of nails can mean chronic lung or heart diseases. Sometimes whitening might indicate kidney or heart disease. Brittleness alerts us to consider if the thyroid is working properly or if the person may have anemia. If theres clubbing of the tip of the nail and texture changes, there could be an underlying lung problem. If I see concerning nail symptoms, I will look into it further. Often dermatologists are the first doctors to notice not-yet-diagnosed health problems.
Also, if you notice a new brown or black stripe, theres a risk of melanoma under the nailor it may just be a freckle or due to a nail infection or inflammation. Its important to understand that most melanomas under the nail are not caused by sun damage, but by random mutationsif you have one, you just got unlucky.
New stripes going down the nail need to be checked out by a dermatologist. A red stripe or lifting of nail from the nail bed could indicate another type of skin cancer.
Yale Medicine is unique in that our staff includes highly trained dermatologists also trained in pathology, called dermatopathologists, who look under the microscope to confirm whether the problem is a nail fungus or another skin disease such as melanoma or another skin cancer. And if so, they help us make the right diagnosis.

What Causes Nail Fungus With Acrylic Nails
I often got questioned from women like do acrylic nails cause fungus. So, the answer is Yes, it can. Acrylic nails may look great, but if not taken care properly or fixed with care, they can lead to nail fungus. Which will be a nightmare for most of the women.
There could be several reason because of which Acrylic nails can cause fungus on your nails.
Below are the common causes of such fungus.
The moisture under the fake nails
The thin moisture layer, under the acrylic nail provides shelter for the fungus. Fungus can only grow when there is moisture on your skin. Moreover, if somebody is not hygiene conscious.
Another primary factor that can cause nail fungus through acrylic nails, is the duration.
Keeping acrylic nails for more than two months is risky. They are more likely to develop nail fungus.
Dirty manicure tools can cause fungus
Dirty manicure tools may have bacterial or fungal spores on them. Always choose a reliable salon, with the clean tools.
Sanitized tools are the best for manicures. Fungus spores are invisible but they are the most strongest living cells, and can survive in various situations.
Many professional salons ensure to use new manicure tools for every new customer.
The last a customer can ask for is to check if the tools are clean, and they have sterilized them live in front of them keep in mind that prevention is better than cure.
Other factors contributing for nail fungus
We cannot blame the tools only.
Living With A Nail Fungal Infection
If you have a nail fungal infection, some things can help:
- Keep your nails cut short and file down any thick areas.
- Dont use the same nail trimmer and file on healthy nails and infected nails. If you have your nails professionally manicured, bring your own nail file and trimmer from home.
- Wear waterproof gloves for wet work . Wear 100% cotton gloves for dry work.
- Wear socks made of wicking material . This pulls moisture away from the skin. Change your socks when they are damp from sweat or if your feet get wet. Put on clean, dry socks every day. Put over-the-counter antifungal foot powder inside your socks to keep your feet dry.
- Wear shoes with good support and a wide toe area. Dont wear pointed shoes that press your toes together.
- Avoid walking barefoot in public areas, such as locker rooms.

What Causes Fungal Nails And What Are Some Of The Risk Factors
In normal, healthy people, fungal infections of the nails are most commonly caused by fungus that is caught from moist, wet areas. Communal showers, such as those at a gym or swimming pools, are common sources. Going to nail salons that use inadequate sanitization of instruments in addition to living with family members who have fungal nails are also risk factors. Athletes have been proven to be more susceptible to nail fungus. This is presumed to be due to the wearing of tight-fitting, sweaty shoes associated with repetitive trauma to the toenails. Having athlete’s foot makes it more likely that the fungus will infect your toenails. Repetitive trauma also weakens the nail, which makes the nail more susceptible to fungal infection.
Elderly people and people with certain underlying disease states are also at higher risk. Anything that impairs your immune system can make you prone to getting infected with the fungus. These include conditions such as AIDS, diabetes, cancer, psoriasis, or taking any immunosuppressive medications like steroids.

How Would I Know If I Have A Nail Infection
Fungus grows in warm, moist places such as under nails. When fungus has a chance to grow in the nail, it can turn into a fungal infection, which is a common problem. Typical signs of a fungal infection include new white or yellow patches and streaks, but nails can also turn brown or green. Youll see lifting of the nail from the skin underneath, and sometimes you will see thickening of the nail. The nail will look bumpy or have ridges with crumbly debris underneath. It may even be so misshapen that it seems to be veering off to the side, or the nail may fall off completely.
If the infection is caused by bacteria instead of a fungus, you may notice redness, swelling, pain or pus in the skin surrounding the nail.
