Indented nail beds can be a sign of an underlying health condition. Spoon nails, or koilonychia, are nails that have an indented shape, like a spoon. This condition is often caused by iron deficiency, but can also be caused by lupus, heart disease or celiac disease. Beau's lines are another condition that can cause indentations in the nails, and can be triggered by an illness or stress.

Spoon nails, which are caused by iron deficiency, lupus, heart disease or celiac disease
Spoon nails, also known as koilonychia, are nails with an indented shape, like a spoon. They form gradually, with the first sign being a flattened nail, followed by an indentation deep enough to hold a drop of water in the nail bed. The central portion of the nail then becomes depressed as it grows, and the rest of the nail appears elevated. Spoon nails may also appear brittle and thin and feel soft to the touch. They are considered to be a manifestation of something deeper in the body.
Chronic iron deficiency is one of the main causes of spoon nails, as well as other conditions that can lead to malnutrition, such as celiac disease. Endocrine disorders, autoimmune conditions, and nutritional deficiencies are also often causes. Spoon nails can also be a sign of lupus or heart disease.
Spoon nails can sometimes be a cause for concern, pointing to a nutrient deficiency or medical condition. Your healthcare provider can give you tests to determine the underlying cause and provide treatment options for any underlying conditions.

Koilonychia, a condition where nails have an indented shape, like a spoon
Koilonychia, or spoon nails, is a condition where nails have an indented shape, like a spoon. The first sign of spoon nails is a flattened nail, followed by an indentation deep enough to hold a drop of water in the nail bed. The central portion of the nail becomes depressed as it grows, while the rest of the nail appears elevated. Spoon nails may also appear brittle and thin and feel soft to the touch.
Iron deficiency is one of the main causes of spoon nails, along with other conditions that can lead to malnutrition, such as celiac disease. Endocrine disorders, autoimmune conditions, and nutritional deficiencies are also often associated with spoon nails. In some cases, spoon nails can be a sign of lupus or heart disease.
Spoon nails are considered a manifestation of something deeper in the body. They can be triggered by any event that disrupts nail growth, including illnesses and infections. Beau's lines, for example, refer to an abnormality on the nail plate where indentations form and can be caused by illnesses such as COVID-19, strep throat, and pneumonia. Thicker Beau's lines may indicate that an illness or trauma lasted a longer time.
If you have koilonychia, it is recommended to see a healthcare provider. While spoon nails are sometimes not a cause for concern, they often point to a nutrient deficiency or medical condition. Healthcare providers can give you tests to determine the underlying cause of spoon nails and provide treatment options for any underlying conditions.

Beau's lines, which can be triggered by illnesses and infections such as COVID-19, strep throat and pneumonia
Beau's lines are indentations that form on the nail plate. They were named after French physician Joseph Honoré Simon Beau, who first discovered the condition. Beau's lines can appear as moat-like depressions or dents on one or more nails, running horizontally across the nail plate. They can affect all fingernails or toenails, or just a few, such as the thumbs and big toes. Beau's lines are often triggered by illnesses and infections, including COVID-19, strep throat, and pneumonia. They can also be caused by severe stress, which interrupts nail growth.
Beau's lines on all of your nails can indicate an illness or trauma. Multiple Beau's lines on each nail may suggest that an illness or trauma occurred more than once. Thicker Beau's lines could indicate that an illness or trauma lasted longer. Vitamin or nutrient deficiencies can also cause Beau's lines, as they interrupt nail growth.
Spoon nails, or koilonychia, are another condition that can cause indented nail beds. Spoon nails are often a sign of iron deficiency or other conditions such as lupus, heart disease, or celiac disease.

Chronic iron deficiency, which can lead to spoon nails
Indented nail beds can be caused by a number of factors. Beau's lines, for example, are indentations that run horizontally across the nail plate and can be triggered by any event that disrupts nail growth, including illnesses and infections.
Another cause of indented nail beds is spoon nails, or koilonychia. Spoon nails are characterised by thin, brittle nails that appear to be scooped in like a spoon. The first sign of spoon nails is a flattened nail, followed by an indentation deep enough to hold a drop of water. Spoon nails are considered to be a manifestation of something deeper in the body, with chronic iron deficiency being one of the main causes. Iron deficiency may cause irreversible mucosal changes which potentially lead to malignant degeneration. Other causes of spoon nails include malnutrition, chronic blood loss, malabsorption, and conditions such as lupus, heart disease, and celiac disease.
Spoon nails are observed in 5.4% of patients with iron deficiency. They are thought to occur due to the upward deformation of the lateral and distal portions of pliable iron-deficient nail plates under mechanical pressure. Nail matrix changes due to blood flow abnormalities have also been proposed as a pathomechanism. Appropriate workup based on patient profile, clinical history, and physical examination may help to diagnose the underlying systemic condition. Replenishment of iron stores can reverse the condition.

Malnutrition, which can also lead to spoon nails
Indented nail beds can be caused by a number of factors, including Beau's lines, which are moat-like depressions or dents on one or more nails. Beau's lines can be triggered by any event that disrupts nail growth, including illnesses and infections such as COVID-19, strep throat, and pneumonia.
Spoon nails, also known as koilonychia, are indented nails that look like the scooped-in portion of a spoon. They are often a sign of malnutrition, with chronic iron deficiency being one of the main causes. Spoon nails can also be caused by other conditions that can lead to malnutrition, such as celiac disease, lupus, heart disease, and endocrine disorders. In addition to iron deficiency, spoon nails can also be caused by a deficiency of vitamin C, zinc, copper, selenium, cysteine, and other amino acids. Plummer-Vinson syndrome (PVS) is a rare condition that causes iron deficiency anaemia and difficulty swallowing, and about 37-50% of people with PVS experience spoon nails. Hemochromatosis, a genetic disorder that affects iron accumulation, can also cause spoon nails in 49% of cases. People with underactive thyroid (hypothyroidism) may also experience spoon nails, slowed nail growth, and brittle nails. Diabetes may also be a factor due to nutrient deficiencies or blood vessel damage.
Spoon nails are considered a manifestation of something deeper in the body, and they often occur alongside other symptoms related to the underlying condition or deficiency. For example, a 22-year-old female presented with weakness, weight loss, and a low appetite, in addition to spoon nails. Researchers believe that low iron levels could result in poor blood flow to the fingers and toes, weakening the connective tissue under the nail bed and leading to spoon nails.
If you have spoon nails, it is recommended that you see a healthcare provider to determine the underlying cause and receive appropriate treatment.
