Nails are considered a purely aesthetic feature. But, they are more than a platform for nail art and bright colors.
The color, shape, and texture of your natural nails are actually a window into your body. Nail abnormalities can reveal a lot about your overall health. Moreover, they are usually an indicator of a fungal nail infection or injury. However, they may be an indicator of a more serious underlying condition, including cancer. In addition, changes in the nail, like thickening or discoloration may be a sign of various health issues, such as diabetes, anemia, lung and heart conditions, and kidney and liver diseases.
That’s not all, the growth rate of your nails could also reveal a lot about your health. Namely, healthy nails grow about 3.5 millimeters per month. This can be affected by your nutritional status, chronic disease, trauma, medications, and even the aging process itself.
In case you see any dramatic changes in your nails, such as discolorations, swelling, or thickness or shape changes, consult a dermatologist.
Here Is What Your Nails Reveal about Your Health:
1. Brittle, Dry, or Cracked Nails
In case you swim, wash dishes, or use nail polish remover too often, you may experience brittle, dry, or cracked nails. Moreover, if you live in a region with low humidity or your nails are exposed to toxic chemicals frequently, you may also experience these nail abnormalities.
A fungal infection or thyroid disorder, especially hypothyroidism could also lead to these nail abnormalities. You may also experience brittle nails because of vitamin A, B and C deficiency.
2. Yellow Nails
Do your nails look a little yellow to you? That can be an indication of an infection. If your yellow nails also come with frequent trips to the bathroom and feeling tired all the time, that can be a sign of diabetes. It causes the glucose to latch on to the nail’s collagen proteins, causing them to change color from a healthy pink to a sickly yellow.
Clubbing describes when your fingertips become enlarged and the nail becomes curved downward. It can be a sign of low oxygen in your blood and is associated with lung disease. Clubbing can also be related to liver or kidney disease, heart disease, inflammatory bowel disease, and AIDS.
4. White Spots
The white spots on your nails are called leukonychia. They are quite common, and they are most often caused by injuries to the base of the nails, usually by manicure or by hurting your nails through knocking or banging. They can be an allergic reaction to nail products, and they can also be an indication of a mild infection. More often than not, they’re a nutritional deficiency. But you cannot discount the fact that white spots on nails also can be a sign of liver or kidney disease.
5. Darkened Nails
Dark colored lines on your nails are caused by an overproduction of melanocytes, the cells that produce melanin. If that’s not the case, they can be caused by nail fungus infections. Darkened nails can also be an indication of more serious health conditions, like melanoma, psoriasis, and chronic infections.
6. Spoon Nails
If your nails start to curve up at the edges, and have the appearance of a spoon, the medical term for this is koilonychia. This can signify iron deficiency, haemochromatosis (iron overload), Raynaud’s disease or lupus erythematosus (an autoimmune condition).
The most common reason for having lots of “pits” or dents in your nails is psoriasis. However rarer things can cause this too, including autoimmune conditions such as alopecia areata.
8. Vertical Ridges
Aging may lead to vertical ridges, which means that these nail abnormalities aren’t a cause for concern. In fact, they could become more prominent as you get older. Furthermore, they could be caused by magnesium or vitamin B12 deficiency.
9. Horizontal Ridges
These nail abnormalities could be caused by nail trauma or a serious health problem with a high fever, including pneumonia or scarlet fever. According to a dermatologist at the Cleveland Clinic in Ohio, John Anthony, horizontal ridges are triggered by direct trauma to the nail. They could also be caused by a more serious health issue, in which these nail abnormalities are noticed on more than one nail at a time.
What’s more, they could also be caused by severe zinc deficiency, circulatory disease, uncontrolled diabetes, or psoriasis. Also, some horizontal discolorations could be associated with carbon monoxide poisoning, arsenic poisoning, leprosy, malaria, or Hodgkin’s disease.
10. White Nails with a Strip of Pink
Good and healthy nails should have a light pinkish color. They should not be too white in the center and dark around the edges. If you have white nails, this can be a sign of liver problems. If your white nails are accompanied with jaundiced skin, it’s best to see a doctor and check your liver functions.
Nail Biting May Result in Infections
Nail biters are at a higher risk of developing a skin infection known as paronychia, which occurs around the nails. As you bite your nails, yeast, bacteria, and other microorganisms could enter through tiny abrasions or tears, thus resulting in redness, swelling, and pus around the nail.
In some cases, this painful condition has to be treated surgically. Moreover, the American Academy of Dermatology notes that bacterial infections triggered by nail biting are among the most common nail problems.
If you bite your nails and cannot break this habit, you may want to follow these recommendations:
– Start by keeping a journal in order to detect your nail-biting triggers, like watching TV, anxiety, or boredom, and then try to avoid the triggers
– Apply an unpleasant tasting substance to your fingertips, such as hot sauce, vinegar, or store-bought bitter-tasting nail products
– Keep your hands busy with certain activities, including knitting
– Keep your nails manicured or trimmed short
– Use electrical tape or Band-Aids to wrap your fingertips
– Use behavioral therapy, like the Emotional Freedom Techniques or habit reversal training
Keep Your Nails Healthy by Following a Healthy Diet
Following a balanced diet high in whole foods gives your body the right amounts of the minerals and vitamins it needs to function optimally. On the other hand, poor nutrition could contribute to various nutritional deficiencies and chronic conditions. Also, your skin, hair and hails will suffer.
Eat more protein, such as grass-fed meat, whey protein, and free-range eggs to keep your nails healthy. Plus, minerals, antioxidants, and vitamins (including vitamin B7 or biotin) present in berries, leafy green vegetables and other whole foods also have a positive effect on your nail health.
In fact, biotin plays an important role in metabolizing amino acids, fats, and carbohydrates. In addition, it is also responsible for strengthening your nails and hair.
Furthermore, biotin is also found in egg yolks from organic, free-range eggs. You may also want to consume more animal-based omega-3 fatty acids because they may help fight inflammation and keep your nails healthy.
Keep in mind that the perfect ratio of omega-3:omega-6 fats is 1:1. So, reduce your intake of vegetable oils and consume more animal-based omega-3 fatty acids from anchovies, sardines, and krill oil.
