Onychomycosis is a fungal nail infection that discolors, thickens, and separates from the nail bed.
Thick toenails are a common issue, particularly among older adults. One of the primary causes of thick toenails is toenail fungus, which can make the nails appear yellow, brittle, and difficult to trim. When fungi infect the nail, they penetrate deep, causing thickening and hardening. This can also result in discoloration and rough texture.
Aside from toenail fungus, trauma or injury is another reason toenails may become thick. When a toenail is damaged by stubbing, repetitive pressure, or wearing tight shoes, the nail’s growth pattern may change, leading to thickness over time.
Aging also plays a role in nail thickening. As we age, nails grow slower and may naturally become thicker. This process is often exacerbated by reduced blood flow to the extremities, making the nails more prone to fungal infections and brittleness.
Certain medical conditions can also contribute to thick toenails. For example, psoriasis, eczema, and diabetes are known to affect nail health. Peripheral artery disease, which reduces blood flow to the feet, can cause nails to thicken and become discolored.
If your toenails are thickening, it’s essential to consult a healthcare provider or podiatrist. They can help identify the underlying cause and recommend appropriate treatments, whether it’s an antifungal cream, better foot hygiene, or lifestyle adjustments. With the right approach, thickened nails can often be managed and improved over time.
