What your fingernails reveal about your health

Your fingernails may seem like a small part of your body, but they can actually provide valuable insights into your overall health. From the colour and texture to the shape and ridges, paying attention to your nails can help you detect potential health issues early on. Here is a breakdown of what your fingernails reveal about your health:

Colour
Healthy nails typically have a pinkish hue. Changes in colour, such as yellowing or a bluish tint, can indicate underlying health issues. For example:

Yellow nails may suggest a fungal infection or psoriasis.

Bluish nails may signal poor circulation or oxygen levels.

White spots or streaks could indicate a deficiency in minerals like zinc or calcium.

Texture
The texture of your nails can also provide clues about your health:

Brittle nails may be a sign of thyroid problems or nutritional deficiencies.

Pitted nails with small dents or depressions could be linked to conditions like psoriasis or eczema.

Thickened nails may indicate a fungal infection or a lung condition.

Shape
Pay attention to the shape of your nails as well:

Clubbed nails, where the tips of the fingers enlarge and the nails curve around the fingertips, may be associated with lung or heart problems.

Spoon-shaped nails, which curve inward like a spoon, could be a sign of iron deficiency anaemia.

Ridges
Vertical ridges on the nails are usually harmless and can be a normal part of ageing. However, horizontal ridges, also known as Beau’s lines, may indicate more serious conditions like diabetes, malnutrition, or trauma.

Nail Bed
The area beneath your nails, known as the nail bed, can also provide insights:

Pale or white nail beds may suggest anaemia or liver disease.

Red or dark nail beds could be a sign of heart or lung problems.

It is important to note that while changes in your nails can sometimes indicate health issues, they are not definitive diagnostic tools. Consulting a healthcare professional for proper evaluation and diagnosis is crucial if you notice any significant changes in your nails.
