White spots on nails, known as punctate leukonychia, are a common occurrence and usually do not indicate a serious problem. They are most likely caused by minor trauma, such as biting your nails, picking at them, or even a rough manicure. However, in some cases, they may be a sign of a more severe health condition, such as liver disease, diabetes, or vitamin deficiencies. If you have frequent or widespread leukonychia or lines running through your nails, it is recommended to consult a healthcare professional.

Leukonychia
Types of Leukonychia
True leukonychia can be further divided into two categories: total leukonychia and partial leukonychia. Total leukonychia is the whitening of the entire nail plate, usually affecting all 20 nails. Partial leukonychia occurs when just a portion of the nail plate is whitened, affecting one, a few, or all nails.
Apparent leukonychia, also known as pseudo-leukonychia, involves a problem with the nail bed under the nail, not the nail itself. This type of leukonychia is caused by changes in the nail bed that are visible through the nail plate. It is often harmless and caused by minor injuries such as nail biting or may occur during the nail growth process.
Causes of Leukonychia
The most common cause of leukonychia is injury to the base of the nail (the matrix). This can include physical injuries such as accidentally closing your finger in a door, striking your finger with a hammer, or trauma from footwear. Vigorous manicuring, nail biting, and tapping of the nails can also cause leukonychia.
In some cases, leukonychia may be a sign of an underlying systemic disease or condition. It has been associated with liver failure, kidney failure, nephrotic syndrome, protein malabsorption, and protein-losing enteropathies. Additionally, serious infections with high fevers, measles, malaria, herpes, and leprosy may also cause leukonychia.
Other potential causes of leukonychia include allergies, fungal infections, mineral deficiencies, heavy metal poisoning, and inflammatory diseases such as alopecia areata or psoriasis.

Nail biting
White stains on nails are usually the result of a condition called leukonychia, which is a medical term for white discolouration appearing on nails. This condition is derived from the Greek words "leuko" meaning white and "onyx" meaning nail.
Leukonychia is often the result of an injury to the nail matrix, which is the base of the nail where the nail is formed. This injury can occur from various physical traumas, such as accidentally closing your finger in a door, striking your finger with a hammer, or even from nail biting.
While leukonychia is typically harmless, it is important to be mindful of nail biting as a potential cause. If nail biting is a concern, there are several strategies that can help, such as identifying triggers, finding alternative ways to manage stress or anxiety, and keeping your nails trimmed short to make biting more difficult. In more severe cases, behavioural therapy or counselling may be recommended to address the underlying causes of the habit.
Additionally, it is worth noting that white stains on nails can also be caused by other factors, such as allergies, fungal infections, or mineral deficiencies. If you are concerned about the appearance of white stains on your nails, it is always best to consult with a healthcare professional for proper diagnosis and treatment.

Allergies
White spots on your nails, also known as leukonychia, are usually harmless but may indicate an allergic reaction to nail products such as nail polish, gloss, hardener, nail polish remover, fake nails, or chemicals used in the application and removal of acrylic or gel nails. These spots can also be the result of an injury, a side effect of medication, a fungal infection, or a symptom of a more serious medical condition.
Allergic reactions are not the only cause of white spots on nails. They can also be caused by injuries to the nail plate or nail matrix, which can occur through various means, such as bumping or hitting your nails, wearing tight shoes, biting your nails, or even from the force applied during manicures.
In rare cases, white spots on nails can be a sign of a more serious medical condition, such as liver disease, anemia, kidney disease, heart failure, or a hereditary condition. Additionally, white spots on nails can be a side effect of certain medications, such as chemotherapy drugs or long-term antibiotics.
If you are concerned about the appearance of white spots on your nails, it is always best to consult a doctor or dermatologist, who can help determine the underlying cause and recommend appropriate treatment or management options.

Fungal infections
White spots on your nails, also known as leukonychia, are usually harmless but may indicate an underlying fungal infection. Leukonychia is derived from the Greek words "leuko" meaning white, and "onyx" meaning nail. It is a common condition that causes white spots or streaks on your fingernails or toenails.
Types of Leukonychia
The three main types of leukonychia are apparent, true, and pseudoleukonychia.
Apparent Leukonychia
Apparent leukonychia involves white spots that appear on the nail bed, or the skin beneath the nail. These spots disappear when pressure is applied to the nail and do not migrate as the nail grows. This type of leukonychia is typically caused by minor injuries such as nail biting or may occur during the nail growth process.
True Leukonychia
True leukonychia occurs when white spots form at the nail matrix, the beginning edge of the nail located under the skin. These spots appear on the nail plate and do not disappear with pressure. They are caused by irritants or allergens present in nail care products like nail polish, remover, glue, or artificial nails.
Pseudoleukonychia
Pseudoleukonychia is caused by a fungus growing on the outside or between the layers of the nail. It causes the upper layers of the nail plate to become scaly and appear white. This type of leukonychia can be treated with antifungal medications.
Diagnosis and Treatment
If you notice white spots on your nails and suspect a fungal infection, it is recommended to consult a healthcare provider. They may suggest a potassium hydroxide (KOH) preparation or fungal culture test, where nail clippings are examined for the presence of fungi. If a fungal infection is confirmed, antifungal medications can be prescribed.
In conclusion, while leukonychia is usually harmless, it is important to be mindful of potential fungal infections that may require medical attention and treatment.

Medication side effects
White spots on your nails, known as leukonychia, are common and usually harmless. They are often the result of a nail injury, such as accidentally closing your finger in a door or biting your nails. However, in some cases, they can be a side effect of certain medications.
Certain medications and treatments can cause white spots or lines on your nails, known as transverse and longitudinal leukonychia. These are common side effects of cancer treatments, including chemotherapy drugs like Hydrea (hydroxyurea), Zolinza (vorinostat), and Bicnu (carmustine). Sulfonamides, a family of antibiotics used to treat bacterial infections, have also been linked to leukonychia. Additionally, retinoids, medications derived from vitamin A, including Soriatane (acitretin), have been associated with nail discolouration.
Heavy metal poisoning from high levels of metals like arsenic, lead, strontium, and thallium can also cause leukonychia. This can occur from exposure to toxic metals in the environment or as a side effect of certain medications. If you suspect heavy metal poisoning, it is important to seek immediate medical attention and get tested through a blood test.
While rare, leukonychia can also be a sign of underlying systemic diseases or conditions, such as diabetes, heart failure, HIV, liver cirrhosis, or psoriasis. In these cases, the white spots on your nails signal that there is a problem elsewhere in your body.
If you notice persistent or recurrent white spots on your nails, it is advisable to consult a doctor. They can evaluate your nails, review your medical history, and perform any necessary tests to determine the underlying cause and provide appropriate treatment or management options.

Frequently asked questions
White stains on your nails are usually harmless but may indicate a medical condition.
There are three types of leukonychia: true leukonychia, apparent leukonychia, and pseudoleukonychia. True leukonychia occurs when the white spots on your nails form at the nail matrix. Apparent leukonychia happens when the white spots form on the skin beneath the nail (nail bed), rather than on the nail itself. Pseudoleukonychia is caused by a fungus growing on the outside of the nail, causing the upper layers of the nail plate to become scaly.
The most common cause of leukonychia is trauma or injury to the nail. This can include biting your nails, picking at them, or having a nail bend back due to injury. Other causes include allergies to nail products, fungal infections, and certain medications. In rare cases, leukonychia can be a sign of a more serious medical condition such as liver failure or kidney disease.
In most cases, leukonychia will resolve on its own and does not require treatment. If the leukonychia is caused by a fungal infection, antifungal medications can be used. Proper nail care can also help prevent leukonychia caused by trauma or injury.
If you are concerned about white stains on your nails or if they do not go away on their own, it is recommended that you see a doctor or healthcare provider for further evaluation and possible testing.
