Are your fingernails curling? It could be a natural trait, or it could indicate an underlying health issue. Curving fingernails, also known as spoon nails, can be caused by various factors, including nutritional deficiencies, respiratory problems, and certain medical conditions. While it may be harmless, it is important to consult a healthcare professional to rule out any potential health concerns. Changes in nail shape, texture, and strength can be indicative of iron deficiency, vitamin B12 deficiency, zinc or biotin deficiency, or underlying conditions such as fungal infections, psoriasis, or thyroid disorders. Understanding the causes of nail curvature can help address any health issues and promote healthy nail growth.

What You'll Learn
Curved nails can be genetic
Curved nails can be harmless and may even be genetic. Nails that curve over the fingertips are often the result of a thickening of the tissue underneath the nail, which may be caused by increased blood flow to the fingertips. This can run in families and may not be a cause for concern. However, it could also be due to an underlying health issue, especially if it occurs later in life. Curved nails may be a sign of an iron deficiency, which is the most common nutritional deficiency worldwide, or other nutritional deficiencies. In some cases, curved nails can be a symptom of a chronic disease, such as lupus, or an autoimmune disorder, such as psoriasis.
In infants, curved nails are common and usually resolve over time. However, if you notice any changes in your nail shape, it is recommended to seek medical advice as it could indicate a health condition or genetic disorder. For example, koilonychia, a condition where nails curve outward, has been linked to a genetic propensity for increased automatic curvature force. Additionally, pincer nails, which are caused by the absence of upward mechanical forces, may also have a genetic component.
While curved nails can sometimes be harmless, it is always a good idea to consult a healthcare professional if you notice any persistent or noticeable changes in your nail shape. They can help identify any underlying issues and advise on the best course of treatment.
There are also some general tips to keep in mind for nail health. Avoiding alcohol use disorder and heavy drinking can help prevent cirrhosis of the liver, which can cause nail changes. Additionally, maintaining a well-balanced diet with sufficient folate, protein, and vitamin C can support nail health and prevent nutritional deficiencies that may impact nail shape.

They may indicate an iron deficiency
Koilonychia is a condition that affects the shape of nails, causing them to curve like a spoon. It is often a sign of another condition, with dietary iron deficiency being the most common cause. Iron is essential for maintaining healthy cells, skin, hair, and nails. A lack of iron can lead to weak, curled nails.
Iron deficiency anaemia is the world's most common nutritional deficiency disease, typically affecting children and women of childbearing age. It can result from a diet lacking in folate, protein, and vitamin C. People who live at high altitudes may also be at risk of developing koilonychia due to the decreased oxygen levels at high elevations. When the body senses low oxygen levels, it produces extra red blood cells, requiring more iron. This can leave the body deficient in iron.
In addition to dietary factors, iron deficiency can be caused by certain health conditions. For example, people with psoriasis, an autoimmune disorder affecting the skin and nails, may be at risk of developing koilonychia. About 90% of people with psoriasis experience changes in their nails at some point, including thickening, curving, and the formation of shallow or deep holes in the nail.
If you suspect you have an iron deficiency, it is important to consult a healthcare professional. They may recommend dietary changes or iron supplementation to help correct the deficiency and improve nail health.

Fungal infections can cause nails to curve
Fingernails curling can be harmless and may be caused by increased blood flow to the fingertips. However, it can also be a sign of an underlying health issue, such as a fungal infection.
Fungal nail infections, or onychomycosis, are common and can affect both the fingernails and toenails. Toenails are, however, more frequently affected than fingernails. These infections are caused by fungi that thrive in warm, dark, and moist environments, such as the feet. Walking barefoot in places like communal showers, locker rooms, and gyms can increase the risk of contracting a fungal nail infection.
Dermatophytes, a type of mold, are the most common cause of toenail fungal infections, accounting for about 90% of cases. These microscopic organisms feed on keratin, a protein that makes up the main structural material of nails, making them hard. Other types of fungi can also infect the nails, and they are often contagious and can be spread through direct contact or by touching infected surfaces.
Fungal nail infections can cause the nail to become thickened, distorted, and discolored, typically yellow. The nails may also become brittle and crumbly, with pieces breaking off. In some cases, the infection may cause pain or discomfort, especially when pressure is applied to the affected nail.
If you suspect a fungal nail infection, it is recommended to seek medical advice. A healthcare provider will examine the affected nail and may take a small sample for testing to confirm the presence of a fungal infection. Treatment options include antifungal medications, such as terbinafine and itraconazole, which are effective in about 60% to 80% of cases. Laser treatment is also an emerging option for stubborn infections, but it is not yet widely recommended due to limited evidence.

Underlying health issues may be a factor
Curved nails, or koilonychia, can be a sign of underlying health issues. This condition can be triggered by various factors, including nutritional deficiencies, autoimmune conditions, and respiratory problems.
One of the most common causes of koilonychia is iron deficiency, which can lead to weak and curled nails. Other nutrient deficiencies, such as a lack of vitamin B12, zinc, or biotin, can also contribute to nail curvature. Dietary changes that include essential nutrients can help nails recover their usual shape. However, it is important to consult a doctor before taking any supplements, as they can have adverse effects.
In some cases, curved nails may be a symptom of more serious health conditions. For example, about 90% of people with psoriasis, an autoimmune disorder, develop nail changes at some point. Additionally, conditions like hypothyroidism, lung diseases, and liver issues can also affect nail growth and appearance. Curved nails can also be associated with anemia, a condition characterized by a low red blood cell count, which can result in nail changes.
While nail curvature may not always indicate a serious health issue, it is important to monitor any changes in nail shape and consult a healthcare professional if concerns arise. Curved nails can sometimes be a natural trait, and they may also be influenced by environmental factors, such as working with certain products or living at high altitudes, which can increase the risk of koilonychia.

Environmental factors could be the cause
One of the most common causes of koilonychia is iron deficiency, which is the world's most common nutritional deficiency. People who do not consume enough folate, protein, and vitamin C can develop an iron deficiency. In addition, people who live at high altitudes have a higher risk of developing koilonychia because the body produces extra red blood cells when oxygen levels are low, and this process requires iron.
Other nutrient deficiencies can also affect nail shape and strength. For example, low levels of vitamin B12 may cause changes in nail texture and structure. Deficiencies in zinc or biotin can also impact nail health. Dietary changes can help nails recover their usual shape, but this can take time.
In some cases, curling fingernails can be caused by exposure to certain substances. For instance, people who frequently work with products that contain petroleum, such as hairstylists, may have an increased risk of developing koilonychia.
