Curved fingernails can be a sign of a number of health issues. Doctors refer to the condition of soft, curved nails as koilonychia, or 'spoon nails'. This can be harmless, but it may also indicate a health condition, such as iron-deficiency anaemia, or a disease of the heart or lungs. Curved nails can also be a result of wearing shoes that are too tight, or cutting nails improperly.

Curved nails can be a sign of koilonychia, which may indicate health issues such as iron-deficiency anaemia
Koilonychia is characterised by the thickening of the tissue underneath the nail, which causes the fingertips to become rounded and the nails to curve over them. Doctors believe this results from increased blood flow to the fingertips and it can run in families. While it may be harmless, it is important to seek medical advice if the curving of the nails occurs with other symptoms, as it could be a sign of a more serious health condition, especially if it occurs later in life.
One possible health issue indicated by koilonychia is iron-deficiency anaemia. Anaemia is a condition where the body does not have enough healthy red blood cells to carry oxygen to the body's tissues. Iron-deficiency anaemia is the most common type of anaemia and is caused by a lack of iron in the body. This can lead to a decrease in red blood cell production, resulting in less oxygen being delivered to the body's tissues. Symptoms of iron-deficiency anaemia include fatigue, weakness, pale skin, shortness of breath, and chest pain.
Curved nails can also be a sign of clubbing, which is associated with chronic low blood-oxygen levels. Clubbing causes the tips of the fingers to enlarge and the nails to become extremely curved from front to back. It is often a symptom of diseases of the heart or lungs, which can cause chronically low blood-oxygen levels. Diseases that cause malabsorption, such as cystic fibrosis or celiac disease, can also lead to clubbing. Ingrown nails, which are nails that curve far inward at the sides, may be due to wearing tight shoes or cutting the nails improperly.

Curved nails can be a symptom of clubbed fingers, which is often a sign of disease, especially of the heart or lungs
Clubbing of the fingers is a symptom of chronically low blood-oxygen levels, which can be caused by several diseases, including cystic fibrosis, congenital cyanotic heart disease, and several other diseases. The tips of the fingers enlarge and the nails become extremely curved from front to back. The nail beds soften, and the nails may seem to "float" instead of being firmly attached. The nails form a sharper angle with the cuticle.
Curved nails can also be a sign of spoon nails, which is a condition where the nails become so soft and curved that they can hold a droplet of water. Doctors often refer to this as koilonychia. This issue may occur in newborns, but it may resolve without needing treatment. In other cases, and in people of other ages, koilonychia can indicate health issues, such as iron-deficiency anaemia. This involves the thickening of the tissue underneath the nail, causing the fingertips to become rounded and the nails to curve over them. Doctors believe this results from increased blood flow to the fingertips. It can run in families and may be harmless, but it may be due to a health condition, especially if it occurs later in life.
If the curving of the nails occurs with other symptoms, a person should seek medical treatment.

Curved nails can be caused by wearing shoes that are too tight, particularly in the toe box
Curved nails can be a symptom of a number of health issues, including iron-deficiency anaemia, cystic fibrosis, congenital cyanotic heart disease, and several other diseases. Doctors refer to this issue as koilonychia, or 'spoon nails', where the nails become so soft and curved that they can hold a droplet of water. This can be harmless and may occur in newborns, but it can also indicate a health condition, particularly if it occurs later in life.
Clubbing of the fingers or toes can also cause curved nails. This is when the last part of the finger appears large or bulging and may be warm and red. The nail curves downward so it looks like the round part of an upside-down spoon. Clubbing can develop quickly, often within weeks, and can be caused by chronic low blood-oxygen levels. If curving of the nails occurs with other symptoms, it's important to seek medical treatment.

Curved nails can be caused by cutting the nails improperly
Curved nails can be caused by a variety of factors, one of which is cutting the nails improperly. This can lead to ingrown nails, where the nails curve far inward at the sides. This condition can also affect the toenails and is often due to wearing shoes that are too tight.
In some cases, curved nails can be a sign of underlying health issues. For example, spoon nails, also known as koilonychia, can indicate iron-deficiency anaemia. This condition involves the thickening of the tissue underneath the nail, causing the fingertips to become rounded and the nails to curve over them. Doctors believe this is a result of increased blood flow to the fingertips and it can run in families.
Another condition associated with curved nails is clubbing, which can be a symptom of diseases affecting the heart or lungs, resulting in chronically low blood oxygen levels. Diseases that cause malabsorption, such as cystic fibrosis or celiac disease, can also lead to clubbing. In this condition, the tips of the fingers enlarge, and the nails become extremely curved from front to back, forming a sharper angle with the cuticle.
It is important to note that if curving of the nails occurs alongside other symptoms, it is advisable to seek medical treatment. Curved nails in newborns may resolve without treatment, but in older individuals, it could indicate a health condition.

Ingrown nails are another potential cause of curved nails, which can be due to wearing shoes that are too tight or cutting the nails improperly. If curving of the nails occurs with other symptoms, it is important to seek medical treatment.
