The human body can reveal a lot about its inner workings, and nails are no exception. The colour of your nails can indicate a vitamin or mineral deficiency, or even a severe health condition. For example, white nails can be indicative of kidney or liver disorders, or anemia, while bluish nails can suggest that the body isn't getting enough oxygen. Yellow nails are often a sign of a fungal infection, but can also point to lung diseases. Changes in nail colour can be a warning sign of a more serious health issue, so it's important to be aware of what these changes might mean and consult a doctor if you have any concerns.

What You'll Learn
White nails
There are three types of leukonychia: true leukonychia, apparent leukonychia, and pseudoleukonychia. True leukonychia occurs when the white spots form in the area where the nail starts to grow (nail matrix) and appear in the hard part of the nail (nail plate). Apparent leukonychia is characterised by white spots forming in the skin beneath the nail (nail bed). Pseudoleukonychia is caused by outside organisms, such as fungi, and the white spots appear on the surface of the nail.
If you notice persistent or worsening white spots on your nails, it is recommended to consult a doctor or dermatologist. They may perform various tests, including a nail biopsy, blood test, or fungal culture, to determine the underlying cause and provide an appropriate treatment.
Additionally, a specific type of white nails called Terry's nails may indicate a more serious health condition. Terry's nails are characterised by nails that are partially or entirely white with a narrow pink band at the tip. This condition can be a sign of protein deficiency, chronic kidney failure, cirrhosis of the liver, congestive heart failure, or anemia.
While white nails can sometimes indicate a health issue, it is important to remember that nail changes are rarely the first sign of a problem. Other symptoms usually appear first, and not everyone with white nails has an underlying health condition. If you are concerned about the appearance of your nails, it is always best to consult a healthcare professional for a proper diagnosis and treatment.

Yellow nails
Yellow nail syndrome (YNS) is a rare condition characterized by yellow, curved, and thickened nails that may detach from the nail bed and fall off. It usually affects adults over 50, but rare cases have been reported in children. YNS is associated with respiratory symptoms, such as a chronic cough, and lower leg swelling. The exact cause of YNS is unknown, but it may be linked to improper circulation, lymphatic drainage issues, or fluid buildup around the lungs.
If you are concerned about the appearance of your nails, it is recommended to consult a doctor or dermatologist. They can examine your nails and run tests to determine the underlying cause. In the meantime, you can try home remedies, such as trimming your nails frequently, using a nail brush to sweep dirt from underneath your nails, and exposing your nails to fresh air to prevent infections.

Blue nails
When the temperature drops, blood vessels constrict, making it difficult for oxygen-rich blood to reach the skin under your nails, resulting in a blue tinge. This is a temporary effect, and the normal nail color should return once the person warms up. However, if the blue discoloration persists or is not due to low temperatures, it could indicate a more serious issue, and medical attention should be sought.
Several health conditions can cause blue nails, including lung conditions such as pulmonary embolism, pneumonia, asthma, and chronic obstructive pulmonary disease (COPD). Severe illness with COVID-19 can also lead to breathing problems and cyanosis that require immediate medical attention. Heart conditions, such as congenital heart disease, Eisenmenger's syndrome, and congestive heart failure, can affect the oxygen-rich blood reaching body tissues, resulting in cyanosis.
In addition, certain conditions affecting blood cells and vessels can cause blue nails, including polycythemia vera, a type of blood cancer, and methemoglobinemia, a hemoglobin disorder. Issues with hemoglobin, such as in methemoglobinemia, can impact its ability to carry oxygen throughout the body, leading to cyanosis. Raynaud's syndrome, which causes blood vessels in the extremities to constrict due to cold temperatures or stress, can also result in blue nails.
While less common, blue nails can also be related to specific medications or treatments. For example, changes in nail color, including a blue discoloration, can occur during treatment for breast cancer. Additionally, prolonged or high exposure to silver can result in argyria, a condition characterized by bluish-gray staining of the skin.

Red nails
Redness and swelling around a nail could indicate an infection. This is usually treatable with soaks and antibiotics, but if an open sore forms, more extensive treatment is required.
Other possible causes of red nails include vitamin and mineral deficiencies. For example, vitamin B12, iron, zinc, or magnesium deficiencies can cause vertical ridges on the nail beds, while vitamins A and C deficiencies can cause nails to crumble or break easily.
It is worth noting that nail health is often an indicator of poor nutritional intake or poor digestion. As such, red nails could be a sign of an unhealthy diet.
If you are concerned about the appearance of your nails, it is important to consult a healthcare professional. They will be able to determine whether the changes in your nails are harmless or require further medical testing.

Black nails
There are several types of melanonychia:
- Longitudinal melanonychia or melanonychia striata: This type presents as brown, black, or grey bands running from the nail bed to the tip of the nail.
- Diffuse or total melanonychia: This type involves the entire nail turning dark.
- Transverse melanonychia: This type appears as a band running across the width of the nail from one side to the other.
The presence of black nails or melanonychia could be indicative of underlying health issues. It is important to consult a doctor for an accurate diagnosis and appropriate treatment. Melanonychia can have a range of causes, from harmless to potentially fatal. Some possible causes include skin cancer, infection, injury, medication side effects, or chemotherapy. A doctor may perform a biopsy or use a dermatoscope for examination. If melanonychia is noncancerous, treatment may not be necessary. However, if it is malignant, the cancerous area must be removed, which may result in the loss of part or all of the nail.
While nail changes can be indicative of certain conditions, they are rarely the first sign of illness. Other symptoms usually precede nail abnormalities. Additionally, many nail abnormalities are harmless and not indicative of any serious health issues. Nevertheless, if you notice any changes in your nail colour, it is always a good idea to consult a doctor or dermatologist for proper evaluation and advice.
