Our nails not only enhance the beauty of our hands but also serve as indicators of our overall health. Healthy nails are not only strong and attractive but also free from cracks, ridges, and other abnormalities.

Cracked nails, on the other hand, can often be a sign of underlying health problems. In this article, we will explore the potential health issues that can be indicated by cracked nails and how to address them.

Nutritional Deficiencies

Cracked nails can be a sign of nutritional deficiencies, including a lack of essential vitamins and minerals. Insufficient intake of nutrients like biotin, vitamin A, vitamin C, iron, and zinc can weaken the nails, leading to brittleness and cracking.

To address this issue, it is important to incorporate a balanced diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats. If necessary, consult a healthcare professional about taking supplements to meet your nutritional needs.

Dehydration

Dehydration can cause nails to become dry and brittle, leading to cracking. When our bodies lack sufficient hydration, the nails are often the first to show signs.

To prevent dehydration and maintain healthy nails, be sure to drink an adequate amount of water throughout the day. Additionally, applying hand moisturizers regularly can help keep the nails hydrated.

Thyroid Issues

Cracked nails may also indicate an underlying thyroid problem. Both hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid) can cause changes in the nails.

Hypothyroidism can lead to dry, brittle nails that easily crack, while hyperthyroidism can cause nails to become fragile and prone to splitting. If you suspect a thyroid issue, it is important to consult a healthcare professional for proper diagnosis and treatment.

Psoriasis

Psoriasis, a chronic autoimmune condition, can affect the nails, leading to cracked and pitted nails. The condition speeds up the nail growth process, and as a result, the nails may become thickened, discolored, and prone to cracking.

If you notice such symptoms along with skin changes, consult a dermatologist for an accurate diagnosis and appropriate treatment options.

Iron Deficiency Anemia

Iron deficiency anemia is a common condition characterized by low levels of red blood cells, primarily due to a lack of iron in the body. One of the symptoms of iron deficiency anemia is brittle nails that crack easily.

If you suspect anemia, it is crucial to undergo blood tests and consult a healthcare professional who can provide guidance on treating the underlying cause and improving nail health.

Fungal Infections

Fungal infections can also cause cracked nails. Nail fungus, known as onychomycosis, can make the nails thick, discolored, and brittle. Cracks may appear as the infection progresses.

Seeking medical attention from a dermatologist or podiatrist is essential to properly diagnose and treat fungal nail infections. They may recommend antifungal medications or other appropriate treatments.

Raynaud’s Disease

Raynaud’s disease is a condition that affects blood circulation in the extremities, such as the fingers and toes. During an episode, the affected areas may experience a restricted blood flow, leading to coldness, numbness, and even color changes.

In severe cases, it can cause the nails to become brittle and crack. If you suspect Raynaud’s disease, consult a healthcare professional for evaluation and management strategies.

Chemical Exposure

Excessive exposure to chemicals and harsh substances can weaken and damage the nails. Regularly using nail polish remover, cleaning agents, or other chemicals without proper protection can lead to dryness and subsequent cracking.

To prevent this, always wear protective gloves when handling such substances and be mindful of the potential harm they can cause to your nails and overall health.

Autoimmune Disorders

Cracked nails can sometimes be associated with certain autoimmune disorders, such as systemic lupus erythematosus (SLE). These disorders can cause multiple symptoms throughout the body, including changes in the nails.

If you suspect an autoimmune disorder may be the underlying cause, it is crucial to consult a healthcare professional for appropriate diagnosis and treatment.

Excessive Handwashing

In the wake of the COVID-19 pandemic, thorough handwashing has become a necessity. However, excessive handwashing, especially with harsh soaps and sanitizers, can strip the nails of moisture, making them dry and prone to cracks.

To address this issue, opt for gentle soaps and moisturize your hands and nails regularly to prevent dehydration and related nail problems.

Conclusion

Cracked nails may seem like a superficial issue, but they can often indicate underlying health problems.

Nutritional deficiencies, dehydration, thyroid issues, psoriasis, iron deficiency anemia, fungal infections, Raynaud’s disease, chemical exposure, autoimmune disorders, and excessive handwashing are all potential causes of cracked nails. If you notice persistent cracking or changes in your nails, it is important to consult a healthcare professional to determine the underlying cause and appropriate treatment options.
