The size and colour of your nails can indicate underlying health conditions. White nails, for example, can be a sign of anaemia, congestive heart failure, or liver disease. White spots on the nails, known as leukonychia, are usually harmless and are often the result of a nail injury, fungal infection, or an allergy. However, in rare cases, they can indicate a more serious medical issue. The lunula, a white half-moon shape at the base of the nail, can also signal underlying diseases if it changes colour or size. For instance, if the lunula turns blue, it could indicate Wilson's disease, a rare inherited genetic disorder.

What You'll Learn
White spots on nails can be caused by frequent manicures
The size of the white half-moon shape, or lunula, at the base of your nail can indicate underlying health issues. For example, if the lunula extends almost to the end of the nail, it could signal chronic renal failure or congestive heart failure. This condition, called Terry's nails, can also be attributed to aging. Lunulae with a bluish tint could suggest Wilson's disease, a rare inherited genetic disorder where copper accumulates in the liver, brain, and other organs. Red lunulae may indicate heart failure, while half-and-half nails, where the white extends halfway up the nail bed, could be a sign of severe kidney disease.
White spots on nails, or leukonychia, are a common condition and are generally harmless. They often appear after minor nail injuries, such as bumping or biting your nails. However, frequent manicures can also be a cause of these white spots. During a manicure, the pressure applied by the manicurist or the use of electric files can damage the nail beds or nail matrix, leading to the formation of white spots. This type of damage can occur if the manicurist is not gentle enough when using sharp tools or aggressively pushes back the cuticles.
Additionally, repeated manicures can cause nail cracking, peeling, or brittleness. In some cases, the use of certain medications or exposure to heavy metals during manicures can also contribute to the appearance of white spots on nails. It is important to note that white spots on nails can also be a sign of fungal infections or allergic reactions to nail products. If you are concerned about the appearance of white spots on your nails, it is recommended to consult a healthcare professional for proper diagnosis and treatment.
While white spots on nails are usually harmless, they can sometimes be a symptom of a more serious condition, especially if they appear alongside other severe symptoms. In such cases, it is important to seek medical advice. Healthcare providers may recommend tests, such as a biopsy, blood test, or fungal culture, to determine the underlying cause of the white spots.

White nails could be a sign of Terry's nails
Terry's nails are characterised by a "washed out" nail bed, except for a thin reddish-brown strip near the tip. The condition is believed to occur when there are fewer blood vessels and more connective tissue than normal in the nail bed. This results in the nails appearing white. While Terry's nails aren't harmful, they can be a sign of a more serious underlying health issue.
People with Terry's nails typically do not exhibit any other adverse symptoms besides the changes in their nail appearance. However, it is important to consult a doctor if you notice any nail abnormalities, as they can be a sign of certain health issues. Terry's nails have been associated with various conditions, including liver disease, kidney disease, and chronic renal failure.
In some cases, Terry's nails may develop as a part of the normal ageing process, even in individuals without any underlying health conditions. Treatment for Terry's nails typically focuses on addressing the underlying cause. For example, individuals with liver problems or diabetes may require medication or dietary changes.

Horizontal lines on nails may indicate slowed or stopped nail growth
Horizontal lines on your nails, also known as Beau's lines, may indicate slowed or stopped nail growth. These lines are typically caused by an injury or illness that has interrupted your nail growth. They can also be a marker of uncontrolled diabetes, the result of cancer treatment, or exposure to cold temperatures in people with Raynaud's disease, a rare blood vessel disorder.
Beau's lines are horizontal ridges or dents that can appear on one or more fingernails or toenails. They are often a sign of an underlying condition and can be caused by various factors, including nutritional deficiencies, zinc deficiency, iron deficiency, or certain medications. In some cases, Beau's lines may also be a result of damage from using artificial nails or getting frequent gel manicures.
If you notice Beau's lines on your nails, it is important to consult a healthcare provider to determine the underlying cause. Treating the underlying cause will allow new, smooth nails to grow again. In the meantime, you can improve the appearance of your nails by applying moisturizer to your nails and cuticles daily to relieve dry skin or eczema.
It is worth noting that Beau's lines are typically temporary and will grow out gradually as your nails grow. However, if you continue to experience new Beau's lines, it is important to inform your healthcare provider, as it could indicate an underlying condition that is interrupting your nail growth.

White spots on nails can be caused by heavy metal poisoning
The size of the white half-moon shape, or lunula, at the base of your nail can indicate underlying health issues. For example, if the lunula extends almost to the end of the nail, it could signal chronic renal failure or congestive heart failure. This condition, called Terry's nails, can also be attributed to ageing.
White spots on nails, or leukonychia, are a common condition and are generally harmless. They often appear after bumping or biting your nails, but they may have other causes, including fungi, allergies, and certain medications. White spots usually mean that your nails have experienced some form of stress, such as an injury, infection, or allergic reaction.
White spots on your nails can be a sign of heavy metal poisoning from arsenic and lead. If you suspect heavy metal poisoning, it is important to seek medical attention immediately. A blood test can detect abnormal levels of these elements. Heavy metal poisoning may also cause lines to develop on your nail plates.
If you notice persistent or worsening white spots on your nails, it is recommended to consult a doctor. Doctors can perform various tests, including mycology, nail biopsy, and blood tests, to determine the underlying cause and provide an appropriate treatment.

White spots on nails can be a sign of leukonychia
White spots on nails are a common condition and are generally harmless. They often appear after nail biting or bumping your nails, but they may have other causes, including fungi, allergies, and certain medications.
The pattern and number of spots may change as the nail grows, and leukonychia may affect only part of the nail or the whole nail. When it affects part of the nail, it is called leukonychia partialis, and when it affects the whole nail, it is called leukonychia totalis. Leukonychia totalis is often a sign of a serious medical issue, such as liver failure. Leukonychia partialis can be further categorized based on its appearance, with punctuate being the most common type, characterized by small spots or specks on the nail.
While white spots on nails are usually harmless, in rare cases, they can be a sign of a systemic illness or deficiency. Healthcare providers may recommend several tests to help make a diagnosis, including a biopsy, blood test, or fungal culture. Treatment for leukonychia depends on its cause, and it is important to address any underlying health conditions that may be contributing to the condition.
