Your fingernails can tell you a lot about your health. Doctors often look at a patient's hands and nails to get a sense of their general health and the kind of work they do. The colour, shape and texture of your nails can provide clues to conditions or diseases. For example, if the lunula extends almost to the end of the nail, it could be a sign of cirrhosis, chronic renal failure or congestive heart failure. Nail biting or picking has also been linked to anxiety and obsessive-compulsive disorder.

What You'll Learn
Nail biting
Your fingernails can provide hints about your overall health, through their colour, shape and texture. For example, if the lunula extends almost to the end of the nail, making the majority of the nail white except for a narrow band at the top, it could signal cirrhosis, chronic renal failure or congestive heart failure. This condition, called Terry’s nails, can also be attributed to ageing, according to the Mayo Clinic.

Beau's lines
Your nails can give you an insight into your overall health, through their colour, shape and texture. Beau's lines are lines that appear on the nails and may indicate uncontrolled diabetes or the result of cancer treatment or exposure to cold temperatures in people with Raynaud's disease, a rare blood vessel disorder.
The presence of Beau's lines can indicate a temporary or chronic condition. Temporary Beau's lines may be caused by a brief episode of illness, such as a high fever, injury to the nail matrix, or exposure to extreme cold temperatures. On the other hand, chronic Beau's lines can be a sign of more persistent health issues, such as uncontrolled diabetes, peripheral vascular disease, or nutritional deficiencies.
In some cases, Beau's lines may also be a side effect of certain medications or treatments, such as chemotherapy for cancer. Additionally, they can be associated with Raynaud's disease, a rare blood vessel disorder characterised by reduced blood flow to the extremities, typically triggered by cold temperatures or stress.
If you notice Beau's lines on your nails, it is important to consult a healthcare professional, especially if you have other concerning symptoms. They can evaluate your overall health, review your medical history, and recommend appropriate tests or treatments to address any underlying conditions.

Terry's nails
The condition was first described by Richard Terry in 1954, who observed that 82 out of 100 consecutive patients with cirrhosis had white nails. He noted that this coloration was due to opacity of the nail bed. Terry's nails are a type of apparent leukonychia, characterised by ground glass opacification of nearly the entire nail, obliteration of the lunula, and a narrow band of normal, pink nail bed at the distal border.
Your nails can provide hints to the status of your overall health, through their colour, shape and texture. For example, if the lunula extends almost to the end of the nail, making the majority of the nail white except for a narrow band at the top, it could signal Terry's nails.

Nail colour
The colour of your nails can indicate the status of your overall health.
White nails, also known as leukonychia, can be the result of trauma, anaemia, dietary deficiencies, heart or kidney disease, or even poisoning. Nails that are mostly white with darker rims can indicate liver problems, such as hepatitis.
Nails with a bluish tint can mean the body isn't getting enough oxygen, which could indicate a lung problem, such as emphysema, or a heart problem.
Red nails can mean possible heart disease or kidney issues. They are also connected to conditions like psoriasis and lupus.
Yellowish nails that frequently crack or split are likely due to a fungal infection.
Healthy nails are smooth, clear, and strong, and come in a range of colours, depending on your skin colour. They can range from light mauve in darker skin tones to pale pink in lighter skin.

The shape of your nails can indicate your general health and the type of work you do. Spoon-shaped nails that curve inwards (koilonychia) can be a sign of iron-deficiency anaemia. Small dents or pits in your nails can be a sign of nail psoriasis, eczema or alopecia. Deep lines or grooves across your fingernails (Beau's lines) may happen when you're ill but should grow out. Fingernails curving over rounded fingertips (clubbing) can be a sign of many serious, long-term conditions. Vertical ridges can be a sign of ageing.
