Flattened nails are a condition known as koilonychia, or 'spoon nails', which is often associated with nutritional deficiencies such as low levels of iron or vitamin B. The condition can also be caused by thyroid problems. Koilonychia is characterised by soft nails with a spoon-shaped dent, which can hold a drop of water on the nail bed. In some cases, flattened nails can be a harmless trait that runs in the family, but they may also indicate an underlying health issue.

Koilonychia (spoon nails)
Koilonychia, also known as spoon nails, is a condition that causes the nails to flatten and develop concavities. This can occur gradually, with the first sign being flattened nails, followed by the formation of an indentation. The indentation is deep enough to hold a drop of water. Koilonychia is often associated with iron deficiency, as well as vitamin B deficiencies. It is important to note that changes to the nails can indicate underlying health issues, especially when accompanied by other symptoms.
In some cases, nail abnormalities can be a result of environmental factors or ageing. For example, brittle nails are commonly caused by low levels of zinc and iron, as well as thyroid problems. However, they can also be a normal result of ageing.
Nail abnormalities can also be a sign of more serious underlying conditions. For instance, onycholysis, which causes the nails to become loose and detach from the nail bed, can lead to a disappearing nail bed if left untreated. Similarly, clubbing causes the nails to curve downward, and can be a sign of disease in the heart, lung, liver, or intestine.
If you notice any changes to your nails, it is advisable to consult a dermatologist or healthcare professional. They can help identify any potential underlying causes and provide guidance on maintaining nail health.

Iron deficiency
Flattened nails are a symptom of koilonychia, a condition that causes the nails to become soft and develop a spoon-shaped dent. Koilonychia is often associated with iron deficiency, as well as vitamin B deficiencies.
Symptoms of iron deficiency include fatigue, weakness, pale skin, shortness of breath, dizziness, headaches, cold hands and feet, and brittle nails. These symptoms can vary in severity depending on the extent of the iron deficiency. In some cases, iron deficiency can lead to more serious complications, such as heart problems and cognitive issues.
The most common cause of iron deficiency is blood loss, which can occur due to heavy periods, internal bleeding, or frequent blood donation. Other causes include a diet low in iron-rich foods, such as meat, poultry, fish, beans, and dark green leafy vegetables. Certain medical conditions, such as inflammatory bowel disease or coeliac disease, can also affect the body's ability to absorb iron from food.
Treatment for iron deficiency typically involves increasing iron intake through dietary changes or iron supplements. In cases of severe deficiency, iron injections or intravenous iron therapy may be recommended. It is important to address iron deficiency as soon as possible to prevent further complications and improve overall health.

Vitamin B deficiency
Flattened nails are a condition known as koilonychia, which is often associated with iron deficiency. However, it can also be caused by vitamin B deficiency. Koilonychia causes the nails to become soft and develop a spoon-shaped dent. This condition usually occurs gradually, with the first sign being flattened nails, followed by the formation of an indentation deep enough to hold a drop of water.
Vitamin B is essential for maintaining healthy nails, and a deficiency can lead to nail abnormalities such as koilonychia. Vitamin B helps promote nail growth and strength, and a lack of it can result in soft, brittle, or curved nails. In some cases, vitamin B deficiency can also cause nail discolouration, such as white spots or streaks.
It is important to note that nail abnormalities can be a sign of underlying health issues. If you notice any changes in your nails, such as flattening or spoon-shaped dents, it is recommended to consult a dermatologist or healthcare professional. They can help identify any potential nutritional deficiencies or underlying medical conditions that may be causing these nail changes.
Additionally, maintaining a well-balanced diet rich in vitamins and minerals can help promote nail health and prevent vitamin B deficiency. Foods such as meat, poultry, fish, eggs, dairy products, and fortified cereals are good sources of vitamin B. Including these in your diet can help ensure adequate vitamin B intake and support the health of your nails.

Clubbing
Flattened nails are a symptom of koilonychia, also known as spoon nails. This condition is characterised by soft nails with a spoon-shaped dent in them. Koilonychia is often associated with nutritional deficiencies, such as low levels of iron or vitamin B. It can also be caused by other underlying medical conditions.
If you notice your nails starting to curve, it is recommended that you see a board-certified dermatologist. They will be able to assess the cause of the clubbing and advise on any necessary treatment.
There are several potential causes of clubbing, including:
- Lung conditions, such as lung cancer or cystic fibrosis
- Heart disease, such as congenital heart disease or endocarditis
- Inflammatory bowel disease, such as Crohn's disease or ulcerative colitis
- Liver disease, such as cirrhosis or hepatitis
- Kidney disease, such as glomerulonephritis or nephrotic syndrome
It is important to note that clubbing can also be a normal variation in nail shape and may not always indicate an underlying health condition. However, if you are concerned about any changes to your nails, it is always best to seek medical advice.

Beaus lines are depressions that appear across the fingernail. They can be caused by a number of factors, including illness, injury to the nail, eczema around the nail, chemotherapy treatment, or a lack of nutrition. Beaus lines are often a sign of an underlying health issue, particularly if they occur alongside other symptoms. It is important to note that changes to the nails can be harmless and may be a result of ageing or genetic factors. However, if you notice any unusual nail abnormalities, it is recommended that you consult a dermatologist or healthcare professional for further advice and assessment.
Nail abnormalities can provide valuable insights into an individual's health status. For example, flattened nails, or koilonychia, can indicate potential nutritional deficiencies or underlying medical conditions. Beaus lines, characterised by depressions across the fingernail, can occur due to various factors, including illness, injury, eczema, chemotherapy, or inadequate nutrition. These nail changes may suggest an underlying health issue, especially when accompanied by other symptoms. While some nail abnormalities are harmless and related to ageing or genetics, it is always advisable to seek professional advice to ensure proper diagnosis and treatment.
Beaus lines are transverse depressions that appear on the fingernails. They can be indicative of a recent illness, injury, or nutritional deficiency. The presence of Beaus lines can be a useful indicator for healthcare professionals in assessing an individual's overall health. It is important to note that these nail abnormalities are not always a cause for concern and may resolve on their own over time. However, if you notice persistent or severe changes to your nails, it is recommended to consult a healthcare provider for further evaluation and guidance.
In summary, flattened nails and Beaus lines can be indicative of underlying health issues. Koilonychia, or spoon nails, can suggest nutritional deficiencies or medical conditions. Beaus lines, on the other hand, can result from various factors, including illness, injury, eczema, chemotherapy, or inadequate nutrition.
