White spots on nails, also known as leukonychia, are a common occurrence and are usually harmless. They often appear as a result of nail trauma, such as biting your nails, or from a minor injury like bumping your nails against a hard surface. However, white spots can also indicate underlying medical conditions or infections. For example, they may be a sign of vitamin or mineral deficiencies, fungal infections, or even more serious conditions like kidney disease or liver cirrhosis. While often benign, it is important to be aware of any other symptoms and consult a healthcare professional if you have concerns.

What You'll Learn
Leukonychia
True leukonychia is caused by partial or whole nail plate damage due to injury to the nail plate or matrix. It involves intrinsic matrix and plate abnormalities. Keratin disruption with trapped air within the nail plate results in reflection and a lack of transparency. This type of leukonychia is commonly referred to as "nail injury" or "injury to the nail matrix". It can be caused by biting or picking at the nails, minor trauma such as bumping or hitting the nails, wearing tight shoes, or even manicuring.
Apparent leukonychia occurs when the pathology involves subungual tissues or changes in the nail bed that are visible through the nail plate. This type of leukonychia is characterised by patterns such as Terry's nails, half-and-half (or Lindsay's) nails, and Muehrcke's lines. It is typically caused by minor injuries like nail biting or the nail-growing process. Some suggest that it may be caused by calcium deficiency, although this is not supported by research.

Nail trauma
White spots on the nails, a condition known as leukonychia, are usually harmless and may be caused by minor nail trauma. This trauma could be from a rough manicure, excessive tapping of the hands and fingers on a hard surface, or an injury to the nail matrix, which is the base of the nail that produces the nail plate. In addition, habits such as nail biting and cuticle biting can also cause trauma to the nails.
Nail biting can lead to acute paronychia, a type of infection where bacteria get underneath the tissue at the side of the nail, causing swelling and irritation. Repeated trauma to the toenails, caused by ill-fitting shoes, can also lead to deformities in the nails. These deformities may resemble a fungal infection, with nails thickened or discoloured, and can lift away from the nail bed.
Chronic nail-biting can disrupt the nail unit, inflaming the nail matrix and causing horizontal ridging, depressions, and raised areas. The cuticles are almost always damaged, disrupting the nail's waterproof seal, causing nails to thin and peel, and increasing the risk of infection.
Nail injuries can also occur when the nail is cut, torn, smashed, or bruised, or when the nail is torn away from the skin. This can lead to blood trapped under the nail, known as subungual hematoma, which may cause throbbing pain and bluish-black discolouration. If the injury is acute, creating a small hole in the nail can help relieve the pain by draining the accumulated blood.
For more serious nail injuries, it is important to seek medical attention at an urgent care centre or emergency room. Treatment will involve stopping the bleeding and cleaning the wound, and the nail and affected area will be numbed before treatment. In some cases, the nail may need to be removed, and the nail bed repaired.

Systemic diseases
White spots on the nails, also known as leukonychia, are usually harmless and are a common occurrence. They are often the result of minor trauma or injury to the nail, such as biting your nails, wearing shoes that are too tight, or even just from a rough manicure. In addition, white spots can also be caused by fungal infections, which can occur when microbes enter through small cracks in the nails or the surrounding skin.
However, in rare cases, white spots on the nails can be indicative of more serious underlying systemic diseases. Systemic diseases are those that affect the entire body. While not always the case, white spots on the nails can sometimes be a rare symptom of several systemic diseases, including:
- Diabetes
- Heart failure
- HIV
- Liver cirrhosis
- Kidney disease
- Psoriasis
If you are concerned about the presence of white spots on your nails, it is always best to consult a healthcare professional. A full physical examination and comprehensive blood panel may be necessary to determine the underlying cause.

Mineral deficiency
White spots on your nails are a common condition and are usually harmless. They often appear after minor nail trauma, such as biting your nails, or as a result of a fungal infection. However, in some cases, they may be an indication of mineral deficiency.
While it was previously believed that calcium deficiency could be the cause of white spots on nails, this has been debunked by experts. Nutritionist Pooja Makhija clarified that zinc, not calcium, is the mineral associated with this condition. This is because zinc is a micro-trace mineral that the body cannot store, making it crucial to consume a zinc-rich diet.
It is important to note that white spots on nails due to mineral deficiency are typically accompanied by other symptoms related to the deficiency. Additionally, a doctor can determine if you are at risk for any mineral deficiency through a blood test and physical examination. If you suspect a mineral deficiency, it is recommended to consult a healthcare professional for proper diagnosis and treatment.
In summary, while nail injuries and fungal infections are the most common causes of white spots on nails, mineral deficiency, particularly zinc deficiency, can also be a contributing factor. If you notice persistent or worsening white spots, it is advisable to consult a doctor for further evaluation and appropriate treatment.

Allergies
White spots on your nails are a common condition and are usually harmless. They are often the result of a minor injury, like bumping or biting your nails, but they can also be caused by an allergic reaction.
In addition to allergies, white spots on your nails can also be caused by fungal infections, mineral deficiencies, heavy metal poisoning, or certain medications. While rare, white spots on nails can sometimes indicate a more serious underlying condition, such as systemic diseases like diabetes, heart failure, HIV, liver cirrhosis, or psoriasis.
To prevent white spots on your nails, you can take some precautionary measures, such as using protective gloves during activities that may damage your nails and wearing comfortable and protective shoes. It is also important to be cautious when putting down heavy objects near your feet to avoid potential injuries.
