- Toenails thicken with age due to slower cell turnover and reduced blood circulation.
- Keratin buildup, caused by natural processes and stress, contributes to thick nails.
- Fungal infections are a common reason for thickened toenails in older adults.
- Slower nail growth with age exacerbates the appearance of thickened nails.

Toenails often undergo noticeable changes as we age, with one of the most common being thickening. This phenomenon, while natural, can cause discomfort, impact nail care routines, and sometimes lead to secondary health issues if not managed properly.
In this blog post, we will explore why toenails get thick with age. We will delve into the biological, environmental, and lifestyle factors contributing to this change, ensuring clarity and practical value for readers.
Why Do Toenails Get Thick With Age?
Aging brings several physical changes, many of which are gradual and may go unnoticed at first. Among these changes, thick toenails often become a topic of concern. While it may seem like a trivial issue, thickened toenails can be both a cosmetic and a medical concern, affecting quality of life.
Understanding why toenails get thick with age helps to identify preventative measures, manage symptoms, and maintain foot health. By examining the reasons behind this common issue, we can better appreciate how the body evolves over time and what can be done to address these changes effectively.
Natural Aging Process
As we age, the body undergoes wear and tear, and the nails are no exception. The natural aging process leads to slower cell turnover in the nail matrix, the area responsible for nail growth. This slowdown can cause nails to thicken because the cells are produced at a slower rate but stack irregularly.
Reduced blood circulation, which is common with aging, also contributes. Poor circulation means fewer nutrients and less oxygen reach the nail bed, impacting its growth pattern and health. This combination of factors partly answers the question: why do toenails get thick with age?
Keratin Buildup
Toenails are composed primarily of keratin, a protein that strengthens and protects them. Over time, excess keratin can accumulate under the nail plate, causing thickening. This process is called onychauxis.
Keratin buildup occurs naturally with aging, especially if the toenails are exposed to repeated stress, such as tight shoes or trauma. The body’s response to these stressors includes producing more keratin, which leads to thicker nails over time.
Fungal Infections
Fungal infections are a major reason why toenails get thick with age. Older adults are more prone to developing fungal nail infections due to weakened immune systems and reduced circulation. Fungi thrive in warm, damp environments, and nails provide the perfect breeding ground.
When a fungal infection sets in, it causes discoloration, brittleness, and thickening of the toenails. Fungal infections are also highly contagious, making them a common problem in communal areas like swimming pools and gyms. Addressing these infections early is crucial to prevent long-term nail damage.
Reduced Nail Growth Rate
Nail growth slows down significantly with age. On average, fingernails grow about 3.5 millimeters per month, while toenails grow even slower. As growth decreases, the nails may appear thicker because the new cells do not replace the old ones efficiently.
This slowed growth also means that damage or irregularities in the nail plate take longer to grow out, exacerbating the appearance of thickened nails. Understanding the impact of slowed nail growth clarifies another aspect of why toenails get thick with age.
Repeated Trauma to the Toenails
Over the years, toenails endure a significant amount of stress. Wearing ill-fitting shoes, stubbing toes, or engaging in activities that involve repetitive pressure can damage the nail matrix. Trauma often results in a thicker, irregular nail as the body attempts to repair the damage.
For older adults, the cumulative effect of such trauma becomes more evident. A history of repetitive stress and injuries makes toenails more likely to thicken with age.
Chronic Medical Conditions
Certain medical conditions that are more prevalent in older adults can also explain why toenails get thick with age. Conditions such as diabetes, peripheral artery disease, and psoriasis directly impact nail health.
- Diabetes: Poor circulation and high blood sugar levels make individuals with diabetes more prone to thickened nails and fungal infections.
- Peripheral Artery Disease: Reduced blood flow to the extremities slows down nail growth and affects nail health.
- Psoriasis: This autoimmune condition often causes nail thickening, discoloration, and irregular growth.
Managing these underlying conditions is key to addressing thickened toenails in older adults.
Neglect and Poor Nail Care
Toenails require consistent care to remain healthy. Unfortunately, nail care often becomes more challenging with age due to reduced flexibility, arthritis, or other mobility issues. Neglecting nail care can lead to hardened, thick nails over time.
Additionally, older adults may not notice early signs of fungal infections or other nail issues due to reduced sensation or vision problems. This neglect compounds the problem, making toenails thicker and more difficult to manage.
Frequently Asked Questions
Here are some of the related questions people also ask:
Why do toenails get thicker as you get older?
Toenails thicken with age due to slower cell turnover in the nail matrix, reduced blood circulation, keratin buildup, and cumulative stress or trauma to the nails.
What causes keratin buildup in toenails?
Keratin buildup occurs naturally with age and can be triggered by repetitive stress, trauma, or fungal infections, leading to thickened toenails.
How does poor circulation affect toenail thickness?
Poor circulation reduces the supply of oxygen and nutrients to the nail bed, slowing nail growth and contributing to irregular and thickened nails.
Can thick toenails be a sign of a medical condition?
Yes, conditions such as diabetes, psoriasis, and peripheral artery disease can cause thickened toenails by affecting blood flow, immune responses, or nail cell production.
Are fungal infections a common reason for thick toenails?
Yes, fungal infections are one of the leading causes of thickened toenails, especially in older adults, as fungi thrive in warm, damp environments and can infect the nail bed.
Can wearing tight shoes make toenails thicker?
Yes, tight or ill-fitting shoes can cause repeated trauma to toenails, prompting the body to thicken the nails as a protective response.
How can I prevent my toenails from thickening with age?
Prevent thick toenails by maintaining proper foot hygiene, wearing comfortable shoes, trimming nails regularly, and addressing any fungal infections or underlying health issues early.
How does slow nail growth contribute to thick toenails?
Slower nail growth with age allows old cells to accumulate, making the nails appear thicker and less smooth over time.
What treatments are available for thick toenails?
Treatments include regular filing or trimming, using antifungal medications for infections, wearing proper footwear, and consulting a podiatrist for severe cases.
The Bottom Line: Why Do Toenails Get Thick With Age?
The reasons are multifaceted, ranging from natural aging and keratin buildup to fungal infections, trauma, and chronic medical conditions. Reduced circulation, slower nail growth, and challenges in nail care further contribute to this issue.
Understanding the causes provides valuable insights into prevention and management. Regular nail care, wearing comfortable shoes, maintaining proper hygiene, and addressing underlying health conditions can make a significant difference in keeping toenails healthy as we age.
Thick toenails may be a natural part of aging, but they don’t have to diminish quality of life. With proper attention and care, it’s possible to manage this common issue effectively and maintain overall foot health well into the golden years.
