Nails are not just about beauty; they can reveal a lot about a person’s health. Changes in their colour, shape, or texture could indicate underlying health issues or nutrient deficiencies. Many people ignore these small signs, but they might be the body’s way of signaling a more significant concern. Here are 8 nail changes that could point to a hidden disease or deficiency.
Pale or white nails
If the nails appear pale or completely white, it might be a sign of anemia, a condition caused by low red blood cell levels. Anemia results from iron or vitamin B12 deficiency and can lead to fatigue, dizziness, and weakness. If pale nails are accompanied by tiredness or shortness of breath, a doctor’s consultation is essential.
Yellow nails
Yellowing of the nails is commonly caused by fungal infections, but in some cases, it may also indicate lung conditions such as chronic bronchitis. Yellowish nails can result from diabetes or thyroid disorders. If the nails are thickened or brittle along with yellow discoloration, seeking medical advice is recommended.
Brittle and cracked nails
Nails that break easily or crack frequently could be linked to a lack of moisture, but if the problem persists, it might be due to hypothyroidism (underactive thyroid). Brittle nails can also be a sign of deficiencies in biotin (vitamin B7) or iron. A balanced diet rich in vitamins and minerals can help restore nail health.
Spoon-shaped nails
Spoon nails, medically known as koilonychia, appear concave with raised edges. This condition is associated with iron deficiency anemia. People with spoon-shaped nails should consider checking their iron levels, as this could be a sign of poor oxygen circulation in the blood.
Dark lines under the nails
Black or dark brown streaks under the nails should never be ignored, as they could indicate melanoma, a dangerous type of skin cancer. While some harmless conditions may also cause nail discoloration, persistent dark lines should always be checked by a doctor to rule out serious concerns.
Pitted or dented nails
Small dents or pits in the nails may be a sign of psoriasis, an autoimmune condition that affects the skin and nails. In some cases, these changes can also be linked to alopecia areata, a disorder that causes hair loss. If nail pitting is accompanied by joint pain or scaly patches on the skin, medical evaluation is necessary.
Clubbed nails
Clubbed nails occur when the fingertips become enlarged, and the nails curve downward. This condition is often associated with lung disease, heart disease, or liver disorders. It happens due to a lack of oxygen in the blood, and early detection can help address the underlying cause before it worsens.
White spots on nails
Many people notice small white spots on their nails, which are usually harmless. However, persistent white spots might indicate a deficiency in zinc, calcium, or protein. Eating a nutrient-rich diet with essential minerals can help maintain healthy nails and overall well-being.
