Your fingernails can reveal a lot about your health. They are made from keratin, a protein that protects your fingers from trauma. While changes in the colour or texture of your nails are usually harmless, they can sometimes indicate an underlying health issue. For example, white nails could be a sign of liver disease, while yellow nails could indicate a thyroid disorder or lung disease. If you notice any unexplained symptoms or changes in your nails, it's always a good idea to consult a healthcare professional.

White nails could indicate liver disease, kidney disease, diabetes or hepatitis
White nails, also known as Terry's nails, can indicate an underlying health issue. The condition is characterised by nails that are entirely white with a reddish-brown strip near the tip. The white colour may resemble frosted glass, and the nails may lack the typical half-moon shape (lunula) near the cuticles.
Terry's nails are often associated with liver disease, including liver scarring (cirrhosis) and liver failure. In 1954, Richard Terry observed that 82 out of 100 consecutive cirrhosis patients had white nails. In addition to liver problems, Terry's nails can also indicate other serious conditions, such as congestive heart failure, chronic kidney failure, viral hepatitis, peripheral vascular disease, type 2 diabetes, HIV, and skin conditions like vitiligo or tuberculoid leprosy.
While Terry's nails themselves are not harmful and do not require specific treatment, they can be a sign of a more serious underlying medical condition. Therefore, it is important to consult a doctor if you notice any nail abnormalities, as treatment will focus on addressing the underlying cause.
It is worth noting that not everyone with white nails has hepatitis, and nail changes are rarely the first sign of an underlying condition. However, changes in nail colour, shape, or texture can sometimes indicate certain health issues. For example, nails with a bluish tint can suggest insufficient oxygen levels in the body, which could indicate a lung or heart problem.

Yellow nails could be a fungal infection, thyroid disease, lung disease or diabetes
Yellow nails are most commonly caused by fungal infections or the overuse of nail polish. However, if you are not guilty of the latter, yellow nails could be indicative of a more serious underlying health condition.
Fungal nail infections, known as onychomycosis, can affect any part of the toenail, causing it to appear yellow, thicken, crumble, and even cause discomfort when walking. This is easily treatable with oral or topical antifungal medication, although the treatment period can be lengthy.
Yellow nails can also be a symptom of thyroid disease. The thyroid is a small, butterfly-shaped gland located at the base of the neck, just below the Adam's apple. It is part of the endocrine system and plays a crucial role in regulating various metabolic processes in the body. An overactive thyroid, or hyperthyroidism, can cause nails to become misshapen and separate from the nail bed. This condition can lead to weight loss, a rapid heartbeat, and anxiety, among other symptoms.
Lung disease is another potential cause of yellow nails. This is characterised by gradual separation of the nail from the nail bed, known as nail clubbing, and can indicate low oxygen levels in the blood. Other symptoms of lung disease include shortness of breath, a persistent cough, and wheezing.
Finally, yellow nails could be a sign of diabetes. This occurs when glucose attaches to collagen proteins in the nail, turning them from pink to yellow. Other symptoms of diabetes include frequent urination, increased thirst, and fatigue.
If you notice yellow nails, it is important to consider any other symptoms you may be experiencing and consult a doctor, as they can help diagnose and treat any underlying conditions.

Spoon-shaped nails could be a sign of iron deficiency, thyroid issues or psoriasis
Spoon-shaped nails, or koilonychia, can indicate an iron deficiency in the body. This condition is characterised by thin, brittle, concave nail dystrophy, where the central portion of the nail is depressed and the lateral aspects are elevated. It can be found in people of all ages, although it is most common in children and women of childbearing age.
Iron deficiency can occur due to several factors, including an inadequate intake of iron-rich foods, an inability to absorb iron, or blood loss. Certain medical conditions, such as celiac disease, cancer, or intestinal bleeding, can also contribute to iron deficiency. Additionally, people who experience excessive menstruation or those who live at high altitudes may be at a higher risk of developing iron deficiency.
Treating spoon-shaped nails involves addressing the underlying cause. Dietary changes, such as increasing iron-rich foods like beans, lentils, dark chocolate, and leafy greens, can help correct the condition. In some cases, iron supplements may be recommended. It is important to consult a healthcare provider to determine the appropriate course of action.
In addition to iron deficiency, spoon-shaped nails can also be a sign of thyroid issues. Specifically, they may indicate an underactive thyroid, or hypothyroidism, which can cause slow nail growth and brittleness.
Furthermore, spoon-shaped nails can be associated with psoriasis, an immune system disorder that affects the skin and nails. Psoriasis typically causes raised, inflamed, scaly patches on the skin and can lead to nail changes, including spoon-shaped nails.

Black lines or spots could indicate trauma, psoriasis, endocarditis or melanoma
The appearance of your nails can be a window to your health. While some nail abnormalities are harmless, others may indicate an underlying issue. Black lines or spots on your nails can be indicative of several conditions, ranging from trauma to more severe possibilities like melanoma.
Black lines on your nails, also known as splinter haemorrhages, can appear brown or dark red and resemble splinters. They are often the result of trauma to the nail, such as accidentally shutting your finger in a door. These lines typically disappear as your nail grows, but if they persist for several weeks, it is recommended to consult a doctor, especially if accompanied by other symptoms like inflamed skin, night sweats, or nail bleeding.
In rare cases, black lines on your nails could be a sign of underlying health issues. One such condition is psoriasis, a chronic skin condition characterised by raised, inflamed, and scaly patches of skin. Psoriasis can also cause nail pitting, resulting in dents or craters in your nails. Additionally, nail changes such as spoon nails, where nails curve inwards and appear thin and brittle, may be associated with psoriasis.
Another potential indication of black lines on your nails is endocarditis, an infection of the heart valves or lining. Endocarditis can cause haemorrhages under the nails, leading to the appearance of black lines. It is important to seek medical attention if you suspect endocarditis, as prompt treatment is crucial for this condition.
Lastly, and most concerningly, black lines or spots on your nails could be a sign of melanoma, the most serious form of skin cancer. Melanoma under the nail is known as acral lentiginous melanoma, and it can manifest as a new or changing dark streak. While not all dark streaks are melanoma, it is essential to consult a dermatologist for a skin cancer check as early detection simplifies treatment.
While nail abnormalities can provide insights into your health, they should not be relied on as the sole indicator of a serious condition. Many nail changes are harmless and may result from lifestyle factors such as manicures or smoking. Nonetheless, if you notice any unusual or persistent changes in your nails, it is always advisable to consult a healthcare professional for proper diagnosis and treatment.

Nail biting could be a sign of anxiety or obsessive-compulsive disorder
The habit of nail biting, or onychophagia, is a common behaviour among children and young adults, with an estimated 28-45% of teenagers biting their nails. While nail biting may be nothing more than a benign habit or a coping mechanism for stress, boredom, or loneliness, it can also be a sign of an underlying mental health issue, such as anxiety or obsessive-compulsive disorder (OCD).
People with OCD often feel powerless to control their compulsions and have no desire to engage in such behaviours. Compulsions are behaviours done to try to prevent a feared outcome or relieve the anxiety that comes from obsessions. Some examples of obsessions may be unwanted thoughts of harming someone, fear of contamination, or a need for symmetry and order. In the context of nail biting, an individual with OCD may bite their nails when they are anxious about an obsession.
Nail biting can also be related to high anxiety and low self-esteem. For example, it may serve as a coping mechanism to deal with nervousness, hunger, or loneliness. In some cases, nail biting can be a symptom of other disorders, such as attention-deficit/hyperactivity disorder (ADHD), separation anxiety, or tic disorder.
When nail biting is a compulsion caused by OCD, it can be treated with a form of cognitive behavioural therapy (CBT) called Exposure and Response Prevention (ERP). ERP involves gradually facing fears and obsessions while resisting the temptation to perform compulsions, thereby reducing the urge over time.
If you are unable to stop biting your nails and feel that it is causing you distress or embarrassment, it is recommended to speak with a doctor or mental health professional. They can help determine if your nail biting is a sign of a deeper issue and provide appropriate treatment or support.
