Concave toenails are more common in fingernails, but when they do occur, they can be a sign of a nail disease called koilonychia, or spoon nails. This abnormality is characterised by thin, brittle, concave nail dystrophy, where the nail plate seems to be centrally depressed and everted laterally. In infants, the nail shape usually becomes regular in time, but concave nails could indicate a genetic disorder.

Koilonychia
Concave toenails are a condition known as koilonychia, derived from the Greek word 'koilos' meaning 'hollow' and 'onikh' meaning 'nail'. It is characterised by thin, brittle, concave nail dystrophy, either placed horizontally or vertically. The condition is more common in fingernails than toenails, and is often easier to spot on fingernails.
The changes in nail shape associated with koilonychia are often described as being able to hold a drop of water on the top of the nail. The nail tends to flatten before developing the characteristic concave shape.

Spoon-shaped nails
Concave toenails are more common in fingernails than toenails, but they can occur. The condition is known as koilonychia, derived from the Greek words 'koilos' (meaning 'hollow') and 'onikh' (meaning 'nail'). It is characterised by thin, brittle, concave nail dystrophy, where the nail plate seems to be centrally depressed and everted laterally. The nail can be placed either horizontally or vertically.
Koilonychia can be either hereditary or acquired. The latter typically occurs in individuals with iron deficiency, trauma, occupational exposures, or diabetes mellitus. It has also been associated with thyroid disorders or autoimmune diseases such as alopecia areata, psoriasis, or lichen planus. In infants, the nail shape usually becomes regular in time, but parents or caregivers who are concerned should speak to a health professional as it could indicate a genetic disorder.

Loss of curvature
Concave toenails are characterised by a loss of curvature, resulting in a spoon-shaped nail. This condition is known as koilonychia, derived from the Greek word 'koilos' meaning 'hollow' and 'onikh' meaning 'nail'. Koilonychia is an abnormality of the nails, causing thin, brittle, concave nail dystrophy that is either placed horizontally or vertically. The nail plate seems to be centrally depressed and everted laterally.
Koilonychia can be either hereditary or acquired. The latter typically occurs in individuals with iron deficiency, trauma, occupational exposures, or diabetes mellitus. In rare cases, it has also been associated with thyroid disorders or autoimmune diseases such as alopecia areata, psoriasis, or lichen planus. In infants, the nail shape usually becomes regular over time. However, parents or caregivers who have concerns should speak to a health professional, as concave nails in infants could indicate a genetic disorder.
Concave nails are easier to spot on fingernails rather than toenails. However, when toenails become concave, they can hold a drop of water on top.

Iron deficiency
Concave toenails, also known as spoon-shaped nails, are a condition called koilonychia. This condition is characterised by thin, brittle, concave nail dystrophy, where the nail plate seems to be centrally depressed and everted laterally. It is more common in fingernails than toenails, but when it does occur in toenails, it can be a sign of iron deficiency.
Symptoms of iron deficiency anaemia include fatigue, weakness, pale skin, shortness of breath, headache, dizziness, cold hands and feet, and brittle nails. In the case of koilonychia, the nails become thin and concave, and may also be brittle or break easily.
Treatment for iron deficiency typically involves increasing iron intake through dietary changes or iron supplements. In cases of severe iron deficiency, intravenous iron therapy or blood transfusions may be recommended. It is important to address iron deficiency as it can lead to serious health complications if left untreated.
