White spots on nails, also known as leukonychia, are usually harmless but can sometimes indicate a medical condition. The spots can be caused by a number of factors, including injury, infection, allergic reaction, and certain hereditary conditions. In some cases, white spots on nails may be a rare symptom of more serious systemic diseases, such as diabetes, heart failure, HIV, or liver cirrhosis.

Injury
White spots on nails, also known as leukonychia, are usually harmless but can be caused by injury. Experts say that the discolouration is most commonly due to injury and is usually not a major cause for concern. However, it is important to note that certain conditions may be associated with white spots or lines on the nail.
Leukonychia can be caused by stress to the nails, such as an injury, like hitting your nail against a hard surface. This type of injury can cause white spots to appear on the nail bed (under the nail) and disappear when pressure is placed on the nail. This is known as apparent leukonychia. True leukonychia, on the other hand, originates from the nail matrix (where your nail grows) and appears on the nail plate.
In addition to injury, white spots on nails can also be caused by infection or an allergic reaction. Certain fungal infections, such as superficial white glycomycosis, can cause a white discolouration of the nail plate. This is characterised by white flaking on the top of the fingernail.
While white spots on nails are usually harmless, they can sometimes be a rare symptom of more serious systemic diseases, including diabetes, heart failure, HIV, liver cirrhosis, and psoriasis. Hereditary conditions, such as Bart-Pumphrey syndrome and Darier disease, may also cause white spots to appear on the nails.

Fungal infection
White spots on nails, also known as leukonychia, are usually harmless but may indicate a medical condition. One of these conditions is a fungal infection. Dr Brendan Camp, a double board-certified dermatologist, explains that some fungal infections can cause a white discolouration of the nail plate, as opposed to the more traditional yellow colour associated with fungal infections. Dr Lal adds that a specific type of fungal infection called superficial white glycomycosis is characterised by white flaking on the top of the fingernail.
It's important to note that not all white spots on nails are caused by fungal infections. Other potential causes include injury, infection, allergic reaction, or certain hereditary conditions. Additionally, white spots on nails can sometimes be a rare symptom of systemic diseases, including diabetes, heart failure, HIV, liver cirrhosis, and psoriasis.
If you notice white spots or lines on your nails and are concerned about a possible fungal infection or other medical condition, it is recommended to consult a healthcare professional, such as a dermatologist, for proper diagnosis and treatment.

Psoriasis
White spots on nails, also known as leukonychia, are usually harmless but may indicate a medical condition. Experts say the discolouration is most commonly due to injury, but it can also be caused by an infection or an allergic reaction.
Leukonychia can be a symptom of many systemic diseases, including psoriasis. Psoriasis is an autoimmune condition that affects the skin. It can cause a variety of symptoms, including red, itchy, and scaly patches on the skin, joint pain, and nail changes. Nail changes associated with psoriasis can include white spots or lines on the nails, as well as pitting, thickening, and crumbling of the nails.
If you notice white spots on your nails, it is important to see a healthcare provider for an accurate diagnosis. While leukonychia is usually harmless, it can be a sign of an underlying medical condition. Treatment for leukonychia will depend on the underlying cause. In the case of psoriasis, treatment options may include topical medications, light therapy, and systemic medications.
It is important to note that psoriasis is a chronic condition, which means there is no cure. However, with proper treatment and management, the symptoms of psoriasis can be controlled. If you have psoriasis, it is important to work with a healthcare provider to develop a treatment plan that is right for you.
Additionally, there are some self-care measures that can help manage the symptoms of psoriasis. These include moisturising the skin regularly, avoiding triggers such as stress and certain foods, and protecting the skin from injury and infection. By following these self-care measures and working with a healthcare provider, individuals with psoriasis can effectively manage their condition and improve their quality of life.
