Your nails can reveal a lot about your health. Doctors can use them to diagnose a range of conditions, from dermatological problems to kidney disease and even autoimmune disorders. For example, if your nails are blue, it could be a sign of low oxygen levels in the blood, which can be caused by lung problems like pneumonia or asthma, or heart problems. Nails that are dimpled or pitted could be a sign of psoriasis, a chronic skin disease, while soft nails that look like they have been scooped out can indicate an iron issue.

Blue nails can signal low oxygen levels in the blood
Nails can reveal a lot about your health. For example, dimpled or pitted nails can be a sign of psoriasis, a chronic skin disease, while soft nails that look like they have been scooped out can be a sign of an iron issue.
Nails that have a blue hue can signal low levels of oxygen in the blood, a condition called cyanosis. This can be caused by many different health issues, including lung problems like pneumonia or asthma, or heart problems.
General practitioner and lecturer in neuroscience and physiology at the University of Bristol, Dan Baumgardt, says that one of the first things he learned in medical school was to look for something called clubbing, where there is a loss of the angle between the nail and the nail bed itself. With clubbing, the nail beds soften, and the nails almost seem to "float" instead of being firmly attached to the finger.
Melanoma can also be detected by the colour of your nail, according to Flowers. "So if you get a solitary new band on a nail, you should definitely see a dermatologist about that," he adds.

Dimpled or pitted nails can point to psoriasis
Nails can be a window to your health. Physicians can use them to diagnose all sorts of conditions, from dermatological problems to kidney disease or even autoimmune disorders.
One nail condition is dimpled or pitted nails, which can point to psoriasis, a chronic skin disease. Psoriasis can also cause the nails to loosen and separate from the nail bed, as can thyroid disease.
Dimpled or pitted nails can be a sign that the skin cells are regenerating too quickly, which is a common symptom of psoriasis. This can cause the nails to become thick and pitted, with small indentations or pits on the surface. The nails may also become discoloured, with a yellow or brown hue.
If you notice that your nails are dimpled or pitted, it is important to see a doctor or dermatologist for further evaluation. They may be able to diagnose psoriasis based on the appearance of your nails, or they may recommend further testing to confirm the diagnosis.
There are treatments available for psoriasis, including topical medications, light therapy, and systemic medications. Early diagnosis and treatment can help to manage the condition and prevent it from worsening.

Terry's nails occur when 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.
If you notice this change in your nail colour, it is important to consult a medical professional. They will be able to assess your individual situation and determine if any further testing or treatment is necessary.
It is worth noting that nail conditions can be indicative of underlying health issues, but they should not be the sole basis for diagnosis. A comprehensive medical evaluation is always recommended to accurately identify and address any potential health concerns.

Nails can reveal a lot about your health. An abnormal nail shape and nail surface can signal a health issue. For example, dimpled or pitted nails can point to psoriasis, a chronic skin disease.

Unlike heart disease, kidney disorders and other conditions, melanoma doesn’t usually cause other noticeable symptoms. However, the colour of your nail could be your only clue. If you get a solitary new band on a nail, you should see a dermatologist about it. If your nails are decorated with an indented horizontal line, that could be a sign that you experienced a serious illness or sustained an injury or shock to your system that caused the nails to temporarily stop growing. These lines, called Beau’s lines, may also be a marker of uncontrolled diabetes or the result of cancer treatment or exposure to cold temperatures in people with Raynaud’s disease, a rare blood vessel disorder.
