The 5 Hidden Things Your TOENAILS Can Reveal about Your Serious Health Problems, From Fungal infection to Deadly Heart Disease

Posted on

TOENAILS aren’t the prettiest part of the human body – but they could tell you a lot about your health.

Nail problems aren’t usually caused by anything serious and it’s normal for then to change over time, but there some instances when you will need to see a GP.

The NHS says most people’s toenails and nails will become more brittle as we age and that pregnancy can also change how soft or hard they are.

It’s also normal for nails to fall off or change colour after an injury.

Dina Gohil, a podiatrist at DG Podiatrist explained how the colour of your nails can reveal various health conditions from everything to lack of oxygen to a fungal infection.

1. Anaemia

Dina said that pale nails could be a sign of anaemia.

Speaking to the MailOnline she explained that usually they are just a sign of ageing.

However, you could also be suffering from anaemia if you have black nails.

She said: “Untreated fungal nails can sometimes cause black toenails due to a buildup of debris.

“Toenails are particularly vulnerable to fungal infections because they thrive on moist, warm environments. So, if you notice you have white or yellow nails, get these checked by a podiatrist before they turn black.”

Dina added that the most common cause of black nails is Melanoma.

Melanoma is caused by skin cells that begin to develop abnormally and exposure to ultraviolet (UV) light from the sun is thought to cause most melanomas.

There is also evidence to suggest that some are caused by sunbed exposure.

Dina said that you should speak to your GP if brown or black spots start to appear under your nail bed.

2. Diabetes

People who have type 1 diabetes have to keep an eye on their feet and should have them checked as part of their annual diabetic review.

The NHS says that diabetes can reduce the blood supply to your feet and cause a loss of feeling known as peripheral neuropathy.

This can mean foot injuries don’t heal well and you may not notice if your foot is sore or injured, it states.

Dina said that there are a number of ways your feet can reveal diabetes.

Pale nails, black nails and even yellow nails can all be signs that you have diabetes.

But most of the time, yellow nails are caused by nail varnish or the food you eat.

3. Lack of oxygen

Dina explained that bluish nails are often due to the fact that not enough oxygen is getting into the blood stream.

She said: “This is a lack of oxygen in the red blood cells causing the skin underneath your nails and other body parts including the feet, lips and mucous membranes to appear blue/purple,’ she explains.

“This has several causes including cold temperature exposure, abnormally high hemoglobin levels, an underlying health problem such as asthma or COPD or your body’s inability to deliver enough oxygen to the area.”

4. Fungal infection

Yellow, black and white spots on toenails can all be signs of fungal infections.

White spots on nails are associated with a zinc deficiency or fungal infection, while untreated fungal nails can sometimes cause black toenails due to a buildup of debris.

White spots are usually nothing to worry about, but Dina said you should get them checked out if they are entirely white.

Dina added that your toenails can be particularly vulnerable to fungal infection because they thrive on warm, moist environments.

If you notice that you have white or yellow nails, Dina said you should get this checked out before they go black.

5. Heart disease

Your toenail health can sometimes reveal underlying conditions and Dina said that one of these could be heart disease.

If you are suffering from heart disease then you could have black nails.

However if you are able to control the underlying health condition then the blackness should go away.
