White nails can be indicative of a range of conditions, including anaemia, overuse of nail polish, weak nails, kidney disease, heart disease, diabetes, rheumatoid arthritis and liver disease. The presence of one white nail, in particular, can be caused by mechanical trauma, such as an injury to the nail. This condition is known as leukonychia and can also be caused by an allergic reaction, an infection or as a side effect of medication.

What You'll Learn

White nails can be a sign of anemia
There are several potential causes of white nails, including injury, infection, or an allergic reaction. In some cases, white nails can be a sign of more serious underlying health conditions, such as kidney disease, liver disease, or heart disease. Therefore, it is important to consult a healthcare professional if you notice persistent or concerning changes in your nail colour.
One of the most common causes of white nails is leukonychia, which is a medical term for white discolouration appearing on nails. It is derived from the Greek words "leuko" (white) and "onyx" (nail). Leukonychia totalis refers to the whitening of the entire nail and usually occurs on all nails. However, it is important to note that the whitening of only one nail is not typically recognised as a symptom of leukonychia totalis but rather as a result of mechanical trauma.
Leukonychia can be a clinical sign of hypoalbuminaemia, which is characterised by low albumin levels in the blood. This can be associated with nephrotic syndrome, a form of kidney failure, as well as liver failure, protein malabsorption, and protein-losing enteropathies. Additionally, a genetic condition or certain medications, such as sulphonamides (a family of antibiotics), can also cause leukonychia.

White nails can be caused by overuse of nail polish
In some cases, white nails may be a symptom of leukonychia, which is a medical term for white discoloration appearing on nails. Leukonychia totalis is a whitening of the entire nail and usually occurs on all nails. However, the whitening of one entire nail is not recognised as a symptom of leukonychia totalis but is likely the result of mechanical trauma. This could be caused by striking the fingertip or repeated trauma to the nails.
If you are experiencing white nails, it is important to consult a healthcare professional to determine the underlying cause and receive appropriate treatment.

White nails can be a sign of kidney disease
White nails can be indicative of a number of conditions, including anemia, overuse of nail polish, weak nails, heart disease, diabetes, rheumatoid arthritis, and liver disease. However, one of the most common causes of white nails is kidney disease. Whole nail whitening is generally seen in cases of kidney problems, where there is protein deficiency in the body. This condition is known as leukonychia totalis and may be a clinical sign of hypoalbuminaemia (low albumin), which can be seen in nephrotic syndrome (a form of kidney failure).
Leukonychia totalis is characterised by a whitening of the entire nail and mostly likely occurs on all nails. However, it is important to note that whitening of one, and only one, entire nail is not recognised as a symptom of leukonychia totalis but as a likely result of mechanical trauma. This could include striking the fingertip or repeated trauma to the nails.
In some cases, white nails may also be caused by a fungal infection, especially when whitening is associated with thickened nail plates. Additionally, white spots on nails can be indicative of previous trauma to the nail plate or an allergic reaction to nail products.

White nails can be a sign of liver disease
Leukonychia is the medical term for white discoloration appearing on nails. It is derived from the Greek words leuko 'white' and onyx 'nail'. The most common cause is injury to the base of the nail (the matrix) where the nail is formed. This condition consists of a whitening of the entire nail and mostly likely occurs on all nails. Whitening of one, and only one, entire nail is not recognised as a symptom of leukonychia totalis but as a likely result of mechanical trauma. Leukonychia totalis may be a clinical sign of hypoalbuminaemia (low albumin), which can be seen in nephrotic syndrome (a form of kidney failure), liver failure, protein malabsorption and protein-losing enteropathies.
White spots usually mean that your nails have experienced some sort of stress. The stress could be from an injury, like hitting your nail against a hard surface, an infection or an allergic reaction. White spots are sometimes the side effects of medications. Your immune system may interpret products that you use on your nails as allergens and cause white spots to form.
Healthy nails are generally pink. Very pale nails may indicate illnesses, such as anemia, congestive heart failure or liver disease. Poor nutrition may also be a culprit. Random white spots that appear on the nails are generally harmless and caused by an injury, such as striking the fingertip or repeated trauma to the nails.
