Long nails curling can be harmless and may be caused by increased blood flow to the fingertips, but it can also indicate an underlying health issue. Curved nails can sometimes be a symptom of an iron deficiency, fungal infection, or chronic condition such as psoriasis. In some cases, nail curvature can be indicative of more serious health concerns, including heart and lung disease, and even cancer. It is recommended that individuals with curved nails consult a doctor or chiropodist, especially if the curvature is accompanied by other symptoms.

What You'll Learn
Curved nails can indicate a health condition
While curved nails can be harmless, they can sometimes indicate an underlying health condition. Nails that curve over the fingertips are known as koilonychia, which may be a sign of iron-deficiency anaemia. This condition involves the thickening of tissue underneath the nail, causing the fingertips to become rounded. Doctors believe this results from increased blood flow to the fingertips. It can run in families and may be harmless, but it may also be due to a health condition, especially if it occurs later in life.
Curved nails can also be a symptom of hemochromatosis, a rare genetic disorder that causes the body to absorb too much iron from food. This condition can lead to a buildup of 5 grams or more of iron in the body, which can damage the liver, heart, and pancreas. Additionally, about 90% of people with psoriasis, a condition that affects the skin and nails, will experience changes to their nails at some point. These changes can include curving, thickening, and the appearance of shallow or deep holes in the nail.
In some cases, curved nails can be a result of improper nail care practices, such as wearing shoes that are too tight or cutting the nails incorrectly, leading to ingrown nails. However, if the curving of the nails is a recent change and is accompanied by other symptoms, it is recommended to consult a doctor or dermatologist to rule out any potential health issues.
While it is important to be aware of potential health indications, it is also worth noting that nail abnormalities are common and can be influenced by various factors, including environmental factors and the use of certain nail products or treatments, such as acrylic nails. Consulting a healthcare professional can help provide personalized advice and recommendations to address any concerns regarding nail health and potential underlying conditions.

Hormonal shifts cause hair changes
While there are several reasons why long nails may curl, one potential factor is nutritional deficiencies, particularly iron deficiency, which can cause spoon nails, or koilonychia. This condition is characterised by nails that become so soft and curved that they can hold a droplet of water. In addition to iron deficiency, a lack of calcium may also contribute to nail curvature.
It is important to note that hormonal shifts can also cause hair changes. While there is limited direct evidence linking hormonal changes to nail growth patterns, it is known that hormones play a significant role in hair growth and texture. Similar to how hormonal shifts can alter hair texture, it is plausible that they could also influence nail structure and growth patterns over time.
Hormonal shifts can indeed cause hair changes, and these shifts are often associated with various stages of life, such as puberty, pregnancy, and menopause. During puberty, increasing levels of androgens can lead to changes in hair texture and growth patterns. For example, individuals may experience their hair becoming curlier or straighter, thicker or thinner, or developing a different shape along the hairline. Pregnancy also involves significant hormonal changes, which can result in thicker and healthier hair due to increased levels of oestrogen. However, following pregnancy, oestrogen levels drop, and many new mothers experience hair loss or a change in texture.
Additionally, menopause is a life stage characterised by a significant decrease in hormone production, particularly oestrogen. This hormonal shift can lead to changes in hair texture and thickness, often resulting in hair that is finer and more brittle. It is important to note that hormonal shifts during menopause can also impact nail health, potentially causing them to become brittle or softer, which may contribute to curling over time.
While hormonal shifts can cause hair changes, it is important to consult a doctor or dermatologist if you notice sudden or persistent changes in your nail growth, as this could indicate an underlying health issue.

Genetic disorders cause iron absorption
While the shape of one's nails can vary due to genetic factors, abnormalities in nail growth could also indicate underlying health issues. Curved nails, for instance, can sometimes be a symptom of iron deficiency anemia. This is a common type of anemia caused by insufficient iron in the body, resulting in a lack of healthy red blood cells that carry oxygen to the body's tissues. Without enough iron, the body cannot produce enough hemoglobin, leading to fatigue and shortness of breath.
Several factors can contribute to iron deficiency anemia. One of them is an inability to absorb iron due to intestinal disorders such as celiac disease, which impairs the intestine's ability to absorb nutrients from food. Additionally, surgical removal or bypass of a portion of the small intestine can affect iron absorption. Pregnant women are also at risk due to the increased demand for iron during pregnancy. Breast milk or formula may not provide sufficient iron for infants, especially those born prematurely or with low birth weight. Women in general are more susceptible because of blood loss during menstruation.
In rare cases, genetic disorders can cause issues with iron absorption and result in either iron deficiency or overload. Hemochromatosis, also known as iron overload, is a condition where the body stores excessive amounts of iron. This disorder is often genetic and can lead to serious damage to vital organs, including the heart, liver, and pancreas. Primary hemochromatosis, the most common type, is caused by an inherited genetic change where both parents contribute DNA that causes the body to absorb too much iron. On the other hand, a rare genetic disorder called Raynaud's can cause the body to absorb an excessive amount of iron from the diet.
While iron deficiency anemia can often be corrected with iron supplementation, it is important to consult a doctor for a proper diagnosis and treatment plan. Self-diagnosis and treatment are not recommended as overloading the body with iron can be dangerous and lead to complications. Similarly, those experiencing nail abnormalities are advised to consult a doctor, especially if other symptoms are present, to rule out any underlying health issues.

Improper nail cutting causes ingrown nails
Nails that are cut too short, ripped, or cut in a rounded shape can become ingrown as they grow back. Cutting your nails too short can cause the skin on the sides to cover the corners of the nail, resulting in the nail growing back into the skin. Nails that are ripped or cut in a rounded shape often become ingrown because they lack clear corners. As they grow, a new corner grows under the skin and gets stuck. Therefore, it is important to trim your nails properly and cut them straight across, leaving enough length so that the corners do not tuck into the skin.
Ingrown nails can occur on both finger and toenails, although they usually affect the big toe. They can be caused by various factors, including improper nail cutting, tight or ill-fitting shoes, toe injuries, and repetitive activities. If left untreated, ingrown nails can increase the risk of infection.
To prevent ingrown nails, it is recommended to cut your nails straight across, ensuring that the corners are not tapered or rounded. Soaking your nails in warm water before cutting them can also help. It is important to use proper nail-cutting tools and avoid tearing or ripping your nails. Additionally, wearing shoes that fit correctly and allow your toes to move freely is crucial in preventing ingrown nails.
If you develop an ingrown nail, there are several treatment options available. Soaking the affected area in warm water or saltwater can help relieve discomfort and prevent infection. Gently lifting the edge of the nail and placing a small piece of cotton or dental floss between the nail and your skin can help the nail grow above the skin. Applying antibiotic cream and wearing roomy shoes or sandals can also aid in the healing process. However, if symptoms persist or worsen, it is important to consult a healthcare professional for further treatment options, such as nail avulsion or partial nail removal.

Increased blood flow thickens tissue under nails
While the shape of your nails can be influenced by genetics, and some people's nails naturally grow in a curved shape, there are also underlying health issues that could be causing your nails to curl. Curving of the nails can sometimes be indicative of an iron deficiency, such as anaemia, or other health conditions, especially if it occurs later in life. Doctors believe that increased blood flow to the fingertips can cause a thickening of the tissue underneath the nail, which then pushes the nail upwards. This thickening of tissue can also be caused by a fungal infection or chronic conditions such as psoriasis.
If you are concerned about the curvature of your nails, it is recommended that you consult a doctor, especially if it is accompanied by other symptoms. A doctor will be able to identify any underlying issues and advise on the best course of treatment. In some cases, changes in nail shape and curvature can be harmless, and a chiropodist or nail technician may be able to advise on how to achieve proper nail regrowth.
It is worth noting that abnormalities in nail growth can sometimes indicate more serious health issues. For example, one person shared their experience on a forum, where they discovered that their curved nails were linked to cancer in both lungs. While this may be an extreme case, it highlights the importance of seeking medical advice if you are concerned about any changes in your nail growth.
While it is important to be vigilant and proactive about your health, it is also crucial to consult reliable medical sources and professionals rather than relying solely on information found on forums or social media. Each person's experience is unique, and a doctor can provide personalized advice and treatment options.
