Pink nails are normal, but any deviation could indicate an underlying health issue
The pinkish hue of nails is a normal and healthy colour. However, any significant deviation from this shade could indicate an underlying health issue. Nails are made of a protein called keratin, and changes in their colour, shape, or texture can signal nutritional deficiencies, infections, or systemic diseases.
For instance, pale or white nails may indicate anaemia or liver disease. Terry's nails, a type of nail discolouration, is characterised by nails that look white or washed-out with a thin, reddish-brown strip near the tip. People with Terry's nails tend to have fewer blood vessels near their nail beds, and it could be a sign of liver disease, congestive heart failure, kidney failure, or viral hepatitis.
Yellow nails can indicate a fungal infection, psoriasis, lung disease, or rheumatoid arthritis. Greenish-black discolouration can be a sign of a bacterial infection, while a blackish tint may suggest chronic kidney disease, adrenal problems, B12 deficiency, liver disease, certain cancers, or melanoma. Bluish nails may indicate poor circulation, respiratory issues, argyria (silver poisoning), Wilson's disease, Raynaud's disease, septicemia, or HIV infection.
Other nail abnormalities include pitting, ridges, brittleness, thickening, or a spoon-shaped appearance. Pitted nails, or dents that look like they were made by an ice pick, can indicate a disease that affects the entire body, such as alopecia areata. Ridges and grooves in the centre of the nail, known as washboard nails, may be caused by the habit of picking or pushing back the cuticles. Spoon-shaped nails, or koilonychia, can indicate iron deficiency.
While nail changes are rarely the first sign of illness, and common issues like bruises, bleeding, and fungal infections can cause discolouration, it is important to be vigilant about any deviations from the normal pinkish hue of nails, as they could provide valuable clues about your overall health.

Fingernails reflect overall health, and changes in colour, shape or texture may be a concern
Fingernails can reflect overall health, and changes in colour, shape, or texture may indicate an underlying health issue. Nails are made of a protein called keratin, and while changes to nails can be harmless, they can also signal disease. A deviation from the normal pinkish hue of nails can indicate an underlying health issue. For example, pale or white nails may indicate anaemia or liver disease, while bluish nails may indicate poor circulation or respiratory issues. Similarly, a blackish tint to the nails can suggest anaemia, bacterial infection, or chronic kidney disease.
In addition to colour changes, nail texture and shape can also provide clues about health. For example, pitted nails, which look like they have been dented by an ice pick, can be a sign of a disease that affects the entire body, such as alopecia areata. Spoon-shaped nails, which are thin and dip down in the middle, can indicate iron deficiency. Ridges and grooves in the centre of the nail, known as washboard nails, may be caused by the habit of picking or pushing back the cuticles. Curved nails, known as clubbing, can be a sign of liver, lung, or heart problems.
Nail changes can be caused by various factors, including bruises, under-the-nail bleeding, and fungal infections, which are common but can be challenging to treat. While nail changes are rarely the first sign of illness, it is essential to pay attention to any persistent symptoms and seek medical advice if needed. A board-certified dermatologist can examine nail changes and provide a diagnosis and treatment plan if necessary.
It is important to note that nail changes can be influenced by factors such as age, sex, and seasonal variations. Nails generally grow faster in young people, males, and during the summer months. Additionally, certain lifestyle habits, such as nail-biting and picking at hangnails, can affect nail health. Maintaining healthy nails includes cleaning them regularly, moisturising, protecting them during chores, and trimming toenails properly to prevent ingrown toenails.

White nails with a pink band could be Terry's nails, a sign of ageing or underlying disease
Changes in the colour of your fingernails can indicate a lot about your overall health and well-being. While nail discolouration may be harmless, it can also be a sign of an underlying disease.
Healthy nails are typically flesh-coloured with white tips and a subtle shine on the cuticles. A deviation from this normal appearance, especially in terms of shape, size, or colour, could be a red flag. For instance, yellow, green, blue, or black nails can be signs of infection, poor circulation, or other health issues.
White nails with a pink band could be indicative of Terry's nails, a type of nail discolouration where most of the nail appears white with a thin reddish-brown or pink strip near the tip. People with Terry's nails do not have a half-moon shape (lunula) near their cuticles, and instead, the entire nail looks washed out. This condition usually affects all the fingernails, but it can also be present in just one fingernail or toenail.
Terry's nails can be a sign of ageing, with experts suggesting that people with this condition have fewer blood vessels near their nail beds. However, it can also indicate an underlying disease or medical condition. For example, people with liver failure or liver disease are more likely to have Terry's nails. Other associated conditions include congestive heart failure, kidney failure, viral hepatitis, and diabetes.

Pink nails are healthy, but pale nails could indicate anaemia or liver disease
The human body can reveal a lot about a person's health, and nails are no exception. Anatomically, nails are horn-like envelopes covering the tips of fingers and toes in humans, most non-human primates, and a few other mammals.
In a healthy individual, nails should have a normal pinkish hue with white tips and a subtle shine on the cuticles. This is because nails are made of a protein called keratin, and changes in their colour, shape, or texture can be a sign of an underlying health condition such as nutritional deficiencies, infections, or systemic diseases.
Other nail discolourations can also indicate various health issues. For example, yellow nails can indicate a fungal infection or psoriasis, while bluish nails may suggest poor circulation or respiratory issues. A greenish-black discolouration can be a sign of a bacterial infection, and black nails can indicate chronic kidney disease, adrenal problems, liver disease, or even cancer. Additionally, spoon-shaped nails may be a sign of iron deficiency, and pitted nails could indicate a disease that affects the entire body, such as alopecia areata.

Healthy nails have a subtle shine, but discolouration could indicate an infection or disease
Healthy nails are typically flesh-coloured with white tips and a subtle shine. However, discolouration could indicate an infection or disease. Nails are made of a protein called keratin, and changes in their colour, shape, or texture can be a sign of an underlying health condition.
For example, a pinkish hue is normal for nails, but a deviation from this colour can indicate an underlying health issue. A bluish tint, for instance, could indicate argyria (silver poisoning), hepatolenticular degeneration (Wilson's disease), Raynaud's disease, septicemia (blood poisoning), lung or breathing troubles, a high percentage of abnormal haemoglobin, HIV infection, or a side effect of medication. Pale or white nails may indicate anaemia or liver disease.
Yellow nails can be a sign of a fungal infection, psoriasis, lung disease, or rheumatoid arthritis. Greenish-black discolouration can indicate a bacterial infection, while black nails can suggest anaemia, chronic kidney disease, adrenal problems, B12 deficiency, liver disease, certain forms of cancer or melanoma, or an injury.
Other nail changes to look out for include pitting, ridges, brittleness, thickening, or a spoon-shaped appearance. These can be signs of various conditions, including nutritional deficiencies, infections, or systemic diseases. Beau's lines, for instance, are thin, dip down in the middle, and can be a sign of stress, heart disease, trauma, lupus, low thyroid, or problems with iron levels.
While nail changes can indicate a health issue, they are rarely the first sign of illness. Other symptoms usually appear first. If you notice any persistent changes in your nails, it is important to consult a dermatologist. They can help diagnose and treat any underlying conditions.
