Changes in nail colour can be indicative of underlying health issues. Grey nails can indicate edema, malnutrition, arthritis, glaucoma, lung problems, emphysema, cardio-pulmonary disease, or post-operation side effects. They can also be a symptom of collagen vascular disease, drug toxicity, or hypersensitivity. In some cases, grey nails may be a sign of ageing or Terry's nails, which is a symptom of a chronic condition such as liver failure or diabetes. It is important to consult a doctor if you observe any changes in your nail colour to get an accurate diagnosis and appropriate treatment.

Bacterial infection
Changes in nail colour can be indicative of an underlying health condition. Grey nails can be a symptom of bacterial infection, as well as other conditions such as psoriasis, thyroid disease, or melanoma (skin cancer).
Nail discolouration can be caused by a collagen vascular disease, drug toxicity, or hypersensitivity. For example, the antibiotic minocycline could cause a reaction. In addition, grey nails can be a sign of vitamin B12 deficiency, which is characterised by a blue or blue-black discolouration of the nails.
Another possible cause of grey nails is argyria, a condition resulting from excessive exposure to silver. Argyria causes a progressive, permanent, blue to slate-grey discolouration of the nails, skin, and mucous membranes. This occurs due to the deposition of silver in stromal tissues and basement membranes, with sparing of the epidermis.
It is important to note that changes in nail colour can have various causes and may not always indicate a serious problem. However, if you notice any unusual changes in your nails, it is recommended to consult a doctor or dermatologist for proper diagnosis and treatment.

Vitamin B12 deficiency
Grey nails can be a sign of vitamin B12 deficiency. Vitamin B12 is an essential nutrient that helps keep the body's nerve and blood cells healthy and helps make DNA. Vitamin B12 deficiency can lead to a range of health problems, including anaemia, fatigue, weakness, constipation, loss of appetite, weight loss, and neurological issues such as numbness and tingling in the hands and feet.
Vitamin B12 is naturally found in animal products, including meat, poultry, fish, eggs, and dairy. It can also be found in fortified breakfast cereals and nutritional yeast. For those following a vegan or vegetarian diet, it is important to ensure adequate intake of vitamin B12 through supplementation or dietary sources.
Some people may be at a higher risk of vitamin B12 deficiency, including older adults, those with digestive conditions such as Crohn's disease or coeliac disease, and those who have had weight-loss surgery. Additionally, long-term use of acid-reducing drugs or metformin, a medication commonly used to treat type 2 diabetes, can interfere with vitamin B12 absorption.
If you notice grey nails or other potential symptoms of vitamin B12 deficiency, it is important to consult a healthcare professional. They can perform the necessary tests to determine your vitamin B12 levels and advise you on the best course of action, which may include dietary changes or supplementation.

Kidney disease
Changes in nail colour can indicate a variety of health issues. Grey nails can be a symptom of kidney disease, but they can also indicate a collagen vascular disease, drug toxicity or hypersensitivity, or a vitamin B12 deficiency. In one case, a patient's blue-grey nails were caused by excessive exposure to silver.
Nail discolouration is only a small symptom of underlying health conditions, but it should not be ignored. If you notice changes in your nail colour, you should see a doctor. Only a medical professional can diagnose the cause of nail discolouration.
If you are experiencing any of these symptoms, it is important to see a doctor as soon as possible. They will be able to run tests to determine the cause of your symptoms and provide appropriate treatment. Treatment for kidney disease may include medications, dialysis, or, in some cases, a kidney transplant.
While nail discolouration can be a sign of kidney disease, it is important to remember that it can also be caused by a variety of other factors, including vitamin deficiencies, drug reactions, or exposure to certain chemicals. Therefore, it is always best to consult a medical professional for an accurate diagnosis.

Melanoma
Changes in nail colour can be indicative of a number of underlying health conditions. Nails that are grey in colour could be a sign of melanoma (skin cancer), but they could also be a sign of kidney disease, thyroid disease, psoriasis, or collagen vascular disease. They could also be the result of drug toxicity or hypersensitivity, for example, a reaction to the antibiotic minocycline.
It is important to be aware of the signs and symptoms of melanoma, as early detection is key to successful treatment. If you notice any changes in your nails or skin that concern you, it is important to consult a doctor or dermatologist as soon as possible. They will be able to examine your nails and skin and determine if further testing or treatment is necessary.
In addition to melanoma, there are other potential causes of grey nails that should not be overlooked. For example, argyria, a condition resulting from excessive exposure to silver, can cause a blue to slate grey discolouration of the nail beds. This discolouration is permanent and will not reverse even if the exposure to silver is discontinued. Therefore, it is important to be aware of potential environmental causes of nail discolouration and take steps to avoid them if necessary.

Psoriasis
Grey nails can be indicative of a number of health issues. One potential cause is a vitamin B12 deficiency, which can cause blue or blue-black discolouration of the nails. Another possibility is kidney disease or melanoma (skin cancer). Changes in nail colour can also be a symptom of thyroid disease, psoriasis, or other illnesses.
The exact cause of psoriasis is unknown, but it is believed to be a combination of genetic and environmental factors. Individuals with a family history of psoriasis are at an increased risk of developing the condition. Additionally, certain triggers, such as stress, injury to the skin, and certain medications, can also contribute to the development of psoriasis.
There is currently no cure for psoriasis, but various treatments are available to help manage the symptoms. Topical treatments, such as creams and ointments, can be applied directly to the affected areas to reduce inflammation and slow down the growth of skin cells. Phototherapy, which involves exposing the skin to controlled amounts of natural or artificial light, can also be effective in treating psoriasis. In more severe cases, systemic medications or biologics may be prescribed to help suppress the immune system and reduce the overproduction of skin cells.
It is important to note that nail changes associated with psoriasis may not always be reversible. However, early detection and proper management of the condition can help prevent further nail damage and improve overall nail health. If you notice any changes in your nail colour or texture, it is recommended to consult a dermatologist for a proper diagnosis and treatment plan.
