What You'll Learn
Koilonychia, or 'spoon nails', can be a sign of anaemia
Koilonychia, or spoon nails, can be a sign of anaemia. Spoon nails are characterised by a central depression in the nail deep enough to hold a drop of fluid. This condition is a result of the body not having enough healthy blood cells to carry oxygen to the tissues.
Nails are an extension of the skin and are made from keratin, a super-tough protein that shields the toes and tops of the fingers from trauma. They can reveal a lot about your health. For example, clubbed nails, which are shaped like an upside-down spoon, can be an indicator of a serious underlying condition such as lung cancer. Clubbing occurs when the nail beds soften and the nails seem to "float" instead of being firmly attached to the finger. The fingertips also appear large or bulging. This can be a sign of extremely low blood oxygen levels.
In some cases, lines on the nails could be a sign of an underlying issue, including psoriasis, endocarditis, and nail melanoma. However, they are most likely caused by trauma to the nail, such as accidentally slamming a door on your finger. If the lines are due to an injury, they should disappear over time as your nail grows. If you don’t notice any change over a few weeks, talk with a doctor, especially if you notice other symptoms, like inflamed skin, night sweats, or bleeding in the nail.
There is also the pervasive idea that the white flecks that sometimes turn up – known as leukonychia – are a sign of calcium deficiency. However, scattered white spots on the nails, which usually start appearing around middle-school age, can signify a zinc deficiency.

Clubbed nails can be a sign of lung cancer
Clubbed nails are shaped like upside-down spoons, and can be a sign of lung cancer. This condition is known as clubbing, where the nail beds soften and the nails seem to "float" instead of being firmly attached to the finger. The fingertips also appear large or bulging. Clubbing is a sign of extremely low blood oxygen levels, and while it is most commonly associated with lung cancer, it can also indicate an infection of the lining of the heart chambers and heart valves, among other conditions. If you notice clubbing, it is important to get an x-ray as soon as possible, as it could be a sign of underlying lung cancer.

Lines on nails can be a sign of psoriasis, endocarditis, or nail melanoma
Fingernails can reveal a lot about your health. For example, white flecks on your nails, known as leukonychia, are thought to be a sign of calcium deficiency. However, this is a myth. In reality, these white flecks are more likely to be a sign of a zinc deficiency.
Lines on your nails can be a sign of trauma to your nail, such as accidentally shutting a door on your finger. However, in rare cases, they can be a sign of an underlying issue, such as psoriasis, endocarditis, or nail melanoma. If the lines are due to an injury, they should disappear over time as your nail grows. If you don’t notice any change over a few weeks, talk with a doctor, especially if you notice other symptoms, like inflamed skin, night sweats, or bleeding in the nail.
Other nail conditions include koilonychia, where a person has a central depression in their nail deep enough to hold a drop of fluid, hence the condition is often referred to as "spoon nails". Spoon nails can be a sign of anaemia, when the body doesn't have enough healthy blood cells to carry oxygen to the tissues. Clubbing is another nail condition, where the nail beds soften, and the nails almost seem to "float" instead of being firmly attached to the finger. Clubbing is a sign of extremely low blood oxygen levels and is most commonly associated with lung cancer.

White spots on nails can be a sign of zinc deficiency
Zinc is a mineral that is important for maintaining good health. It can be found in foods such as meat, shellfish, seeds, and legumes. It helps the body to make proteins and DNA, and it also supports the immune system and helps wounds heal.
If you are concerned about the appearance of your nails, it is always a good idea to speak to a doctor or healthcare professional. They can help determine if there is an underlying issue causing the spots and advise you on any necessary treatment.
In addition to zinc deficiency, white spots on nails can also be caused by trauma to the nail, such as accidentally slamming a door on your finger. In most cases, the spots will disappear as your nail grows out. However, if they do not go away or if you notice other symptoms such as inflamed skin, night sweats, or bleeding in the nail, it is important to seek medical advice.
While the appearance of your nails can sometimes indicate an underlying health issue, it is important to remember that not all nail abnormalities are cause for concern. For example, white flecks on the nails, known as leukonychia, were once thought to be a sign of calcium deficiency. However, this idea has been largely debunked, and leukonychia is now considered a normal variation in nail appearance.

White flecks on nails, or leukonychia, can be a sign of calcium deficiency
Additionally, the appearance of your nails can sometimes indicate underlying health conditions. For example, clubbed nails, which are shaped like an upside-down spoon, can be a sign of lung cancer or other serious conditions. Koilonychia, or "spoon nails," can indicate anaemia, which is a lack of healthy blood cells to carry oxygen to the tissues.
Overall, while white flecks on nails may be a sign of calcium deficiency, it is important to consider other potential causes and consult a medical professional if you have any concerns.
