Fungal infections
Curved nails can be a natural trait, but they can also be a sign of nail health issues like fungal infections. Fungal infections can result in thick, brittle nails that may curl downward. As the infection progresses, it can cause discolouration and distortion of the nail shape.
Fungal nail infections are usually not serious, but they can be difficult to treat and may cause the nail to become thick, brittle and crumbly. The nail may also become distorted in shape and lift off the nail bed. In some cases, the nail may become discoloured and turn white, yellow or green.
Fungal nail infections can be treated with antifungal medication, which may be applied directly to the nail or taken orally. In some cases, the infected nail may need to be removed. To prevent fungal nail infections, it is important to keep the nails short and clean, avoid walking barefoot in damp public places, and wear shoes that allow the feet to breathe.

Thyroid disorders
Downward-curved nails, also known as spoon nails, can be a natural trait or a harmless family trait. However, they can also indicate underlying health issues. Curved nails can be a sign of deficiencies, such as iron deficiency or anaemia, or potential respiratory problems, such as asthma, chronic bronchitis, or low oxygen levels. Thyroid disorders, such as hypothyroidism, can also affect nail growth and appearance. Other potential causes of curved nails include fungal infections, psoriasis, and other diseases, such as lung diseases and liver issues. If you notice your nails changing shape, it is recommended to consult a healthcare professional for advice.
The exact mechanism by which thyroid disorders affect nail growth and appearance is not fully understood. However, it is believed that the hormones produced by the thyroid play a crucial role in nail health. When the thyroid is underactive, as in the case of hypothyroidism, it can lead to a decrease in metabolism and a range of other symptoms, including nail changes.
While curved nails can be a sign of thyroid disorders, it is important to note that they can also be caused by a variety of other factors, as mentioned earlier. Therefore, if you notice your nails changing shape, it is always advisable to consult a healthcare professional for a proper diagnosis. They may recommend a thyroid function test, which involves a blood test to measure the levels of thyroid-stimulating hormone (TSH) and thyroxine in the blood.
In addition to nail changes, other symptoms of thyroid disorders may include fatigue, weight gain or loss, hair loss, dry skin, and changes in heart rate. If you are experiencing any of these symptoms, it is important to seek medical advice. Treatment for thyroid disorders typically involves medication to regulate hormone levels, and managing the condition can help improve nail health and overall well-being.

Curved nails can be a sign of iron deficiency, which can cause nails to appear concave or scooped out. Other symptoms of iron deficiency include thin nails with raised ridges, and changes in colour or strength.
People at risk of iron deficiency include those with heavy periods, pregnant women, and individuals with digestive conditions that affect nutrient absorption, such as coeliac disease or Crohn's disease. Vegans and vegetarians may also be at risk if they do not consume enough iron-rich plant-based foods or supplements.
Treatment for iron deficiency typically involves increasing iron intake through diet or supplements. Good sources of iron include red meat, poultry, fish, beans, and dark green leafy vegetables.
