Key Reasons for Age-Related Nail Thickening
Reduced Circulation: Poor blood flow to the feet reduces the supply of nutrients and oxygen, causing nail growth to slow and thickening to occur.
Accumulated Trauma: Years of minor injuries (microtrauma), such as rubbing against shoes or stubbing toes, damage the nail fbed, resulting in thickening.
Slower Cell Turnover: The rate at which new nail cells are produced decreases with age, leading to a build-up.
Fungal Infections (Onychomycosis): Older adults are more susceptible to infections that cause nail thickening.
Systemic Diseases: Conditions like diabetes, peripheral heart disease, or psoriasis can contribute to nail changes.
