Horizontal Lines On Big Toe Nails And Heart Health: What You Need To Know

There is a common belief that horizontal lines on the big toe nails may indicate coronary heart disease. However, according to current clinical research and pathophysiological evidence, there is little to no direct correlation between these nail markings and heart conditions.

Possible Causes Of Horizontal Ridges On Toe Nails

More often than not, horizontal lines on the big toe nails are not a sign of heart disease but rather the result of nutritional deficiencies or fungal infections such as onychomycosis (commonly known as athlete's foot-related nail infection). These ridges can appear due to a lack of essential vitamins and minerals in the body.

Nutritional Deficiencies

If multiple horizontal lines appear across all nails, it could signal a significant deficiency in vitamins or trace elements such as iron, zinc, or biotin. In such cases, it is advisable to visit a healthcare provider for a comprehensive blood test and appropriate supplementation.

Fungal Infections And Nail Separation

When horizontal lines are accompanied by nail separation or discoloration, the cause may be a fungal infection. If this is the case, visiting a dermatologist is highly recommended. Treatment typically involves topical or oral antifungal medications to eliminate the infection and prevent further complications such as foot fungus.
