Nails can reveal a lot about a person's health. Healthy nails are smooth, without ridges, grooves, spots, or discoloration. However, changes in nail color and growth patterns can indicate health concerns. For example, yellow nails can be a sign of aging, nail lacquers, or acrylic nails, or smoking. Beau's lines, or horizontal ridges, can indicate that the body is fighting an illness. Additionally, nail growth can be influenced by factors such as age, hormone levels, overall health, and nutrition. While some nail changes are harmless, others may signal more serious conditions, making it important to consult a healthcare provider for ongoing issues.

Nail growth and factors affecting it, such as age, hormones, and health
Fingernails grow on average about a tenth of a millimeter per day, which equates to around 3.47 millimeters per month. However, there are several factors that can influence the rate of growth, including age, hormone levels, health, and nutrition. Nails on the dominant hand and longer fingers tend to grow faster, and fingernails grow faster during the day and in the summer.
Age plays a significant role in nail growth. As early as age 20, the growth rate slows by about 0.5% per year. This change in speed is likely due to the slowing of blood circulation with age. Nails may also become more brittle and prone to breaking as we age, and conditions like anemia, hardening of the arteries, and hormonal changes can further impact nail texture. Repeated exposure to water, harsh chemicals, and cosmetics can exacerbate these issues. Additionally, vertical ridges often become more prominent with age.
Hormones also influence nail growth and health. For example, during pregnancy, high levels of estrogen and progesterone contribute to rapid nail growth. On the other hand, nail growth may slow during lactation. Puberty is another period of fluctuating hormone levels, with nail growth peaking during this time and declining as hormone levels stabilize with age. Lower levels of estrogen can result in dull, yellowish fingernails.
Health and nutrition are also important factors in nail growth and health. Certain nutritional deficiencies, such as iron deficiency, can cause changes in nail growth and appearance. Spoon nails, or koilonychia, can indicate iron deficiency anemia. Other conditions, such as psoriasis, lichen planus, and dermatitis, can also affect the nails. Nails can also reflect overall health, with conditions like clubbing indicating oxygen deprivation, liver or kidney disease, or endocrine disorders. Yellow nails can be a sign of respiratory issues, thyroid problems, or skin diseases, including cancer.

Changes in nail colour, including yellow nails, which could indicate health issues
Your nails can reveal a lot about your health. While some nail changes are harmless, others can signal health concerns, especially changes in nail colour and growth patterns.
White Nails
White nails, or leukonychia, can be a result of trauma, dietary deficiencies, or injury. They can also indicate more serious health issues such as anemia, heart or kidney disease, poisoning, or liver problems like hepatitis.
Yellow Nails
Yellow nails are often caused by dyes, nail polish, or harsh products. They can also be a sign of a fungal infection, vitamin or mineral deficiencies, or an allergic reaction. In some cases, yellow nails can indicate more serious conditions, including:
- Chronic lung conditions
- Respiratory issues
- Lymphatic obstructions
- Rheumatoid arthritis
- Thyroid conditions
- Psoriasis
- Diabetes
- Skin cancer
Dark Streaks
A new or changing dark streak on the nail could be melanoma, the most serious type of skin cancer. While not all dark streaks are melanoma, it is important to see a dermatologist for an examination.
Blue Nails
Nails with a bluish tint can indicate that the body isn't getting enough oxygen, which could be a sign of a lung problem such as emphysema.
Horizontal Ridges (Beau's Lines)
Horizontal ridges on the nails, also known as Beau's lines, are often caused by reduced nail matrix activity or when the body is fighting an illness. They can also be a side effect of certain medications or surgery.
Vertical Ridges
Vertical ridges are typically a normal sign of aging. However, they can also be caused by alopecia areata (hair loss) or onychorrhexis (splitting).
Clubbing
Clubbing is a condition where the nails become curved and rounded, and it can be an indicator of health issues such as heart disease, liver or kidney disease, or inflammatory bowel disease.
Spoon Nails (Koilonychia)
Spoon nails, or koilonychia, are nails that grow in a pattern resembling a ski jump. This condition can be a sign of iron deficiency anemia.
Pitting
Pitting, or small dents in the nails, could indicate a disease that affects the entire body, such as alopecia areata.
If you notice any significant changes in your nail colour or growth patterns, it is important to consult a healthcare professional for proper diagnosis and treatment.

White spots and lines on nails, which are usually harmless but can indicate liver issues
The appearance of white spots and lines on nails, also known as leukonychia, is generally harmless and can be caused by minor trauma, such as injury or nail-picking. Beau's lines, for instance, are horizontal ridges that occur due to reduced nail matrix activity or when the body is fighting an illness. They can also be side effects of medication or surgery and usually grow out without causing concern. Vertical ridges, on the other hand, are often a normal sign of aging.
However, in some cases, these spots and lines can indicate a severe or worsening health condition that requires medical attention. For instance, white spots and lines on nails can sometimes be a sign of liver issues such as liver disease, liver failure, cirrhosis, or hepatitis. Other potential health concerns indicated by nail abnormalities include diabetes, kidney disease, anemia, dietary deficiencies, heart disease, poisoning, thyroid issues, and skin diseases or cancer.
It is important to consult a healthcare provider if you notice frequent or widespread leukonychia or lines on your nails, as they can help identify and address any underlying health conditions. Nail abnormalities are rarely the first sign of these conditions, but they can provide valuable clues about your overall health.
While the appearance of your nails can offer insights into your health, it is important to remember that nail growth and appearance are influenced by various factors, including age, hormone levels, overall health, and external factors such as frequent nail clipping and nutrition. Maintaining good nail hygiene, such as regular trimming and moisturization, can contribute to overall nail health.

Ridges on nails, which are typically age-related but can signal severe illness
Ridges on nails are typically harmless and can be a normal sign of aging. Vertical ridges, also known as longitudinal striations or bands, are furrows that run from the tip of the fingernail down to the cuticle. They often become more prominent with age, possibly due to a slowing of cell turnover. However, they can also be a sign of vitamin deficiencies, especially zinc and iron deficiencies, or improper nail care.
Horizontal ridges, also known as Beau's lines, are often deeper and can indicate more serious issues. These can be caused by malnutrition, severe nail injury, or certain medications or surgeries. Beau's lines can also be a symptom of serious conditions, such as diabetes, peripheral vascular disease (PAD), or chemotherapy treatment. Repeated Beau's lines could indicate an underlying condition that is interrupting nail growth.
While ridges are usually age-related, they can sometimes signal a more severe illness. If you notice new ridges or lines in your nails, it is important to consult a healthcare provider to determine the underlying cause and rule out any health conditions. Your doctor may examine your nails, ask about other symptoms, and order urine and blood tests to check for potential causes such as nutritional deficiencies, kidney disease, or diabetes.
To improve the appearance of your nails, you can apply moisturizer to your nails and cuticles daily to relieve dry skin. Additionally, you can apply a skin cream to your hands before bed and wear thin cotton gloves while sleeping. For nail growth, biotin supplements are often recommended, but it is important to consult a healthcare provider before adding new supplements to your regimen.

Nail conditions like clubbing, which can indicate oxygen deprivation or liver disease
Fingernails can reveal a lot about a person's health. Healthy nails are smooth, without ridges, grooves, spots or discolouration. However, some nail changes are harmless and natural. For instance, vertical ridges that run from the cuticle to the tip of the nail are common and tend to become more prominent with age.
Nail conditions can sometimes signal underlying medical problems. One such condition is nail clubbing, which is characterised by nails that appear wider, spongy, swollen, or like an upside-down spoon. Clubbing is caused by soft tissue swelling of the terminal phalanx, resulting in the straightening or loss of the angle between the nail bed and the nail. It is often a symptom of another condition, but it can also be idiopathic (without a known cause) or congenital (something you're born with).
Nail clubbing is associated with a wide range of conditions, including cardiac, pulmonary, infectious, neoplastic, inflammatory, and vascular diseases. It can indicate oxygen deprivation in the blood, also known as hypoxemia, which is often linked to lung problems. Additionally, clubbing can result from heart disease or inflammatory bowel disease, both of which can affect oxygen levels in the body.
In some cases, nail clubbing may indicate liver disease. For example, patients undergoing prostaglandin therapy for liver disease have developed clubbing, which reversed upon discontinuing the treatment. Heavy alcohol consumption or alcohol use disorder can also cause cirrhosis of the liver, which has been linked to nail clubbing. Therefore, it is crucial to consult a healthcare provider if you notice any nail changes, as they can be a window into your overall health.
