What You'll Learn
Fungal infections
Nail discolouration can be caused by a variety of factors, including fungal infections. In fact, about 50% of nail dystrophies are caused by a fungal infection (onychomycosis). This is due to common fungi present in the air, dirt, and dust.
Fungal nail infections can be treated with antifungal medications, which may be applied topically or taken orally, depending on the severity of the infection. It is important to consult a doctor if you suspect a fungal nail infection, as they can prescribe the appropriate treatment and advise on prevention measures.
In addition to fungal infections, nail discolouration can also be caused by other factors such as nail injuries, birth deformities, psoriasis, lichen planus, and occasionally tumours (cancerous or noncancerous). Drugs, infections, and diseases can also contribute to nail discolouration. For example, certain medications or chemicals can cause changes in nail colour, and conditions such as diabetes, liver disease, or heart failure may also be factors.

Skin disorders
Nail discolouration can be caused by a variety of skin disorders, infections, and diseases.
Infections with common fungi, bacteria, or yeast present in the air, dirt, and dust can cause nail discolouration. For example, an infection with Pseudomonas bacteria can cause a greenish discolouration, known as Green Nail Syndrome.
Nail discolouration can also be a symptom of skin disorders such as psoriasis, lichen planus, and occasionally tumours (cancerous and noncancerous). Psoriasis is a skin condition that causes the skin to be dry, red, and irritated, and it can also lead to pitting, which refers to small depressions or little pits in the nails.
Additionally, nail discolouration can be a sign of more serious underlying health issues. Melanonychia, for example, refers to dark pigmentation of the nails, which can be a natural occurrence in people with dark skin but can also indicate health issues. Similarly, white nails can signal trauma, liver disease, diabetes, an overactive thyroid, heart failure, heavy metal poisoning, chemotherapy, or a lack of nutrients in the diet.
If you are concerned about any changes in your nail colour, it is important to consult a doctor for an accurate diagnosis.

Chemicals
Nail discolouration can be caused by a variety of factors, including chemicals. This could be due to products used on the nails, such as nail polish or acrylics. It can also be caused by exposure to certain chemicals in the environment, such as heavy metals or toxins. In some cases, nail discolouration may be a sign of a more serious condition, such as heavy metal poisoning, so it is important to see a doctor if you are concerned.
In some cases, nail discolouration may be a sign of a more serious underlying condition. For example, white nails can signal liver disease, diabetes, an overactive thyroid, heart failure, or a lack of nutrients in the diet. Dark streaks or bands on the nails can be a sign of melanonychia, which is a dark pigmentation of the nails that can be caused by an increase in melanin production. This can occur in one or more nails and may be a natural occurrence in people with dark skin.
It is important to note that nail discolouration can have many different causes, and a doctor should be consulted if there is any concern or if the discolouration persists. They will be able to examine the nails and determine the underlying cause.

Melanonychia
Nail discolouration can be caused by a variety of factors, including infections, skin disorders, chemicals, and certain illnesses. One specific type of nail discolouration is Melanonychia, which refers to the dark pigmentation of the nails. This can manifest as black or brown discolouration and can affect one or more nails. While Melanonychia can be a natural occurrence in people with dark skin, it can also indicate potential health issues. An accurate diagnosis is crucial to determine the underlying cause.
There are several possible causes of Melanonychia, and an accurate diagnosis is essential to rule out any serious health concerns. One potential cause is nail injuries, which can lead to melanin production and subsequent nail discolouration. Additionally, certain drugs, infections, and diseases can contribute to Melanonychia. For example, fungal infections, such as onychomycosis, are a common cause of nail dystrophies, which can result in discolouration.
It is important to consult a doctor if you notice any nail discolouration, especially if it is persistent or accompanied by other symptoms. A doctor can examine your nails and determine the underlying cause. While some cases of Melanonychia may be benign, others may indicate more serious health issues that require prompt medical attention.

Chromonychia
Nail discolouration can be caused by a variety of factors, including infections, skin disorders, chemicals, and illnesses. Chromonychia is a term used to describe nail discolouration caused by drugs, infections, or diseases. For example, an infection with Pseudomonas bacteria can cause a greenish discolouration known as Green Nail Syndrome.
In some cases, nail discolouration can be a natural occurrence, such as melanonychia, which is the term for dark pigmentation of the nails. This can be observed in people with dark skin. However, it can also indicate health issues, as melanin, the substance responsible for skin pigmentation, can cause nail discolouration under certain circumstances.
Nail discolouration can also be caused by nail injuries, birth deformities, psoriasis, lichen planus, and occasionally tumours (both cancerous and noncancerous). Additionally, when the nail plate separates from the nail bed, it can cause a white discolouration known as onycholysis, which may be due to infection, trauma, or products used on the nails.
It is important to note that nail discolouration can sometimes signal more serious health issues. For example, white nails can indicate a low red blood cell count, trauma, liver disease, diabetes, an overactive thyroid, heart failure, heavy metal poisoning, chemotherapy, or a lack of nutrients in the diet. Therefore, if you are concerned about any changes in your nail colour, it is recommended to consult a doctor for an accurate diagnosis.
