White spots on nails can be caused by an injury, such as striking your fingertip
White spots on nails can also be caused by zinc or calcium deficiency, fungal infections, or allergic reactions. If most of the nail has turned white, it is likely to be a fungal nail infection or a sign of decreased blood supply to the nail bed, known as 'Terry's nails'. Terry's nails are typically white with reddened or dark tips and can be a sign of a wide range of medical conditions, including liver cirrhosis, iron-deficiency anaemia, liver disease, or diabetes.
If your nails look "scooped out" like a spoon, you may have anaemia, hypothyroidism, or liver problems. Horizontal lines or grooves that run across the nail indicate that your nail growth is slowed or stopped. Common reasons for this include high fever, stress, damage to the cuticle or base of the nail, and some medications.
Nail disorders and diseases may be a sign of problems in the body. Nails can be spoon-shaped, blue, or have white lines. Some nail disorders may indicate diseases ranging from psoriasis to squamous cell carcinoma.

They can also be caused by zinc or calcium deficiency
White spots on nails are generally harmless and caused by an injury, such as striking the fingertip or repeated trauma to the nails from frequent manicures. However, they can also be caused by zinc or calcium deficiency. If you have frequent or widespread white spots on your nails, it's important to speak with a healthcare provider as they might be a sign of a severe or worsening health condition, such as liver disease or diabetes.
Zinc and calcium are essential minerals that play a crucial role in maintaining healthy nails. A deficiency in either of these nutrients can lead to changes in nail colour and texture. For example, zinc deficiency can cause white spots or streaks on the nails, while calcium deficiency can result in brittle or soft nails that are prone to breakage.
In addition to nail changes, zinc and calcium deficiencies can also manifest in other ways. Zinc deficiency may cause symptoms such as hair loss, skin lesions, and a decreased sense of taste or smell. It is often associated with dietary factors, such as a diet low in zinc-rich foods like meat, seafood, and nuts. On the other hand, calcium deficiency can lead to muscle cramps, numbness or tingling in the hands and feet, and, in severe cases, seizures or cardiac arrest. It is commonly linked to conditions that affect calcium absorption, such as vitamin D deficiency or hypoparathyroidism.
To address zinc or calcium deficiency, it is important to make dietary changes that include foods rich in these nutrients. For zinc, this includes incorporating more meat, seafood, legumes, seeds, and dairy products into your diet. Calcium-rich foods include dark, leafy greens, tofu, dairy products, and calcium-fortified foods and beverages. Additionally, supplements can be considered under the guidance of a healthcare professional.

Fungal nail infections can cause nails to turn white
White nails can be caused by a number of factors, including fungal nail infections, which can cause nails to thicken, crumble or detach from the nail bed. If most of the nail has turned white, it is likely to be a fungal nail infection or a sign of decreased blood supply to the nail bed, known as 'Terry's nails'. Terry's nails are typically white with reddened or dark tips and can be a sign of a wide range of medical conditions, including liver cirrhosis, iron-deficiency anaemia, and heart disease.
Fungal nail infections are a common cause of white nails and can be treated with over-the-counter antifungal medications or prescription medications. It is important to treat fungal nail infections early to prevent them from spreading to other nails or the skin.
Other potential causes of white nails include zinc or calcium deficiency, allergic reactions, and repeated trauma to the nails from frequent manicures. In some cases, white nails may be a sign of a more serious underlying health condition, such as liver disease or diabetes.
If you notice white nails, it is important to consult a healthcare professional to determine the underlying cause and receive appropriate treatment.

White nails can be a sign of decreased blood supply to the nail bed, known as 'Terry's nails'
White nails can be a sign of decreased blood supply to the nail bed, known as Terry's nails. This condition is typically characterised by white nails with reddened or darkened tips and can indicate a wide range of medical issues. Terry's nails are often associated with liver cirrhosis, which is a condition that causes scarring and damage to the liver.
In addition to liver problems, Terry's nails can also be a sign of iron-deficiency anaemia. This condition arises when the body lacks sufficient iron, resulting in a reduced number of red blood cells. Anaemia can also manifest as spoon-shaped nails, a condition known as koilonychia. Spoon-shaped nails indicate that the body is not producing enough red blood cells, which can be due to iron deficiency or other nutritional deficiencies.
While white nails can be a cause for concern, it's important to note that random white spots on the nails are generally harmless. These spots are usually the result of minor injuries, such as striking the fingertip or repeated trauma from frequent manicures. Other potential causes of white spots include zinc or calcium deficiency, fungal infections, or allergic reactions. However, if the white spots are frequent or widespread, it is recommended to consult a healthcare professional.
Additionally, nail abnormalities can provide insights into underlying health conditions. For instance, yellow nails are common and may be caused by nail polish stains, smoking, or infections. In some cases, yellow nails can indicate a fungal infection, which may lead to nail thickening, crumbling, or detachment from the nail bed. Therefore, it is important to be mindful of any changes in nail appearance and consult a healthcare provider if there are concerns.
