Flat nails can be a sign of iron deficiency
Koilonychia can often be treated with dietary changes, such as increasing your iron intake. A doctor may take a full medical history, perform a physical exam, and order blood tests to determine the cause of the nail abnormalities. In some cases, iron deficiency can be resolved with adjustments to your diet.
In addition to iron deficiency, nail abnormalities can also be caused by certain diseases and conditions. For example, onycholysis is a condition where the nails become loose and may even detach from the nail bed. White nail syndrome, or leukonychia, can occur with arsenic poisoning, heart disease, renal failure, pneumonia, or hypoalbuminemia. Yellow nail syndrome is often associated with lung disorders and lymphedema, and is characterised by yellow nails that lack a cuticle, grow slowly, and are loose or detached.
While it's important to be aware of potential health issues, it's also worth noting that nail shape can be influenced by external factors. For instance, the use of nail polish can affect nail shape, as it deprives the nails of water and moisture. Additionally, filing your nails can help achieve a more uniform shape if you're concerned about the appearance of flat or curved nails.
