The colour of your fingernails can reveal a lot about your health. While healthy nails are generally pink, any significant deviation from this hue can indicate an underlying health issue. For example, very pale nails may indicate illnesses such as anaemia, congestive heart failure, or liver disease. On the other hand, bluish nails may indicate poor oxygen circulation, heart or lung issues. Nails that are mostly white with a narrow pink band at the tip are a condition called Terry's nails, which can result from ageing, diabetes, or kidney, liver, or heart disease.

What You'll Learn
Pink nail beds are healthy nail beds
The colour pink on your little brother's fingernail beds is a sign of good health. Fingernails are made of a protein called keratin and are produced by living skin cells in the finger. The nail bed is the skin beneath the nail plate, and the nail bed sits on top of tiny blood vessels that feed it and give your nails their
Healthy nails are smooth and have no spots or discolouration. However, changes in colour, texture, or shape can signal health problems. For example, pale or white nails may indicate anaemia or liver disease, while bluish nails may indicate poor circulation or respiratory issues. Greenish-black discolouration can be a sign of a bacterial infection.
It is important to note that not all nail discolouration is a cause for concern. Vertical ridges in your nails may be age-related and are usually harmless. Horizontal ridges, called "Beau's lines," indicate a pause in nail growth that could be related to a health issue. Common causes include high fever, vitamin deficiency, injury, diabetes, and peripheral vascular disease.
If you notice any significant deviation from the normal pinkish hue of nails, it is essential to consult a doctor to rule out any potential health issues.
Therefore, pink nail beds are indeed healthy nail beds, and your little brother's pink nail beds are a good indication of his overall health.

Fungal infections can cause discolouration
The pink colour of your little brother's fingernails is likely due to the tiny blood vessels underneath the nail bed. These blood vessels feed the nail and give it its characteristic pink hue. However, if you notice any discolouration, such as yellow, white, or brown tones, it could indicate a fungal infection, known as mycotic nails.
Mycotic nails are caused by a fungal infection that affects the toenails or fingernails, leading to discolouration and other changes in the nail's appearance and texture. The nail may turn brown, white, or even black, and it often becomes thick and fragile. In some cases, the nail may separate from the nail bed, a condition known as onycholysis.
Fungal infections of the nails are typically not serious, but they can be challenging to treat and may require prolonged treatment. These infections are often associated with constant warmth and dampness, such as wearing trainers for extended periods, resulting in hot and sweaty feet. Additionally, people with weakened immune systems may be more susceptible to fungal nail infections.
To prevent fungal nail infections, it is essential to maintain good foot hygiene and keep the nails clean and dry. Avoiding prolonged periods in tight, enclosed shoes can also help reduce the risk of infection. If your little brother exhibits any signs of fungal infection, it is advisable to consult a healthcare professional for proper diagnosis and treatment.
If left untreated, severe fungal nail infections can lead to nail deformities and further complications. Therefore, it is always best to address any concerns with a qualified healthcare provider, who can recommend appropriate treatments, such as antifungal medications or, in rare cases, minor surgical procedures to remove badly infected nails.

Iron deficiency can cause concave nail beds
Your little brother's fingernail beds are pink because the nail bed sits on top of tiny blood vessels that feed the nails and give them their pink colour.
Iron deficiency can lead to spoon nails due to reduced iron levels in the epithelial cells, causing a disruption and weakening of the subungual connective tissue. This can result in the upward deformation of the lateral and distal flexible nail plates, leading to the concave shape characteristic of spoon nails.
People who follow a vegetarian or vegan diet may be at a higher risk of developing spoon nails due to the potential for lower iron intake. Additionally, certain medical conditions can increase the likelihood of spoon nails, such as lupus, heart disease, celiac disease, or diabetes mellitus. Spoon nails can also be hereditary or congenital, and they are more prevalent in individuals living at high altitudes.
If you notice concave nail beds in your little brother, it is advisable to consult a healthcare professional. They can provide guidance on dietary changes or supplements to address any potential iron deficiency and improve the appearance of the nail beds.

White nails with a pink band is Terry's Nails
The pink colour of your little brother's fingernails is due to the tiny blood vessels that sit under the nail bed. These blood vessels feed the nail and give it its pink hue.
However, if the nail beds are mostly white with a narrow pink band at the tip, this is a condition known as Terry's Nails. Terry's Nails is a type of nail discolouration, named after Dr. Richard Terry, who, in the 1950s, observed that more than 8 out of 10 people with severe liver scarring (cirrhosis) also had white nails. Terry's Nails may also be indicative of other underlying conditions, including kidney disease, diabetes, or heart disease. It is believed that people with Terry's Nails have fewer blood vessels and more connective tissue than normal in the nail bed, causing the nails to appear white.
While Terry's Nails is not harmful in and of itself, it should be evaluated by a doctor, as it can be a sign of a more serious issue. It is also important to note that not everyone with liver disease will have white nails, and not everyone with white nails has liver disease. Terry's Nails may also develop as part of the normal ageing process, and it usually affects all the fingernails, although it can also occur in just one fingernail or toenail.
If you notice any nail abnormalities, it is crucial to consult a doctor, as changes in the colour, shape, or texture of your nails can sometimes indicate certain health issues.

Blue nails could indicate poor circulation
The pink colour of healthy nails comes from the tiny blood vessels that sit underneath the nail bed. Usually, nails are pink and healthy, but sometimes they can be a different colour, which can indicate a problem. For example, blue nails could indicate poor circulation.
Blue nails, or cyanosis, are often the result of poor circulation caused by cold weather. However, there are other factors that may cause this symptom. For instance, blue nails can be caused by a low level or lack of oxygen circulating in the blood, which is often due to cold temperatures forcing the blood vessels to constrict. This results in the skin or membrane below the skin turning a purplish-blue colour.
If your little brother's nail beds are pink, this is a sign of healthy nails. However, if he has blue nails, it could be a sign of poor circulation. If he has any other symptoms, such as swelling in the vocal cords, an asthma attack, or frostbite, this could be a medical emergency.
If your brother's nail beds are a different colour to healthy pink nails, it is important to seek medical advice. A doctor will be able to examine his nails and determine if there is an underlying cause for concern. They may also want to examine his heart.
It is worth noting that changes in nail colour can be caused by various factors, such as infections, skin disorders, or even chemicals. For example, yellow nails can indicate lung diseases, sinusitis, thyroid problems, or rheumatoid arthritis. White nails can signal liver disease, diabetes, or heart failure. Therefore, it is important to consult a doctor if you are concerned about any changes in nail colour or texture.
