Step Smart: The Hidden Impact of BMI on Foot Pain

Abstract

Body Mass Index (BMI) is an important indicator of overall health and has a direct impact on musculoskeletal and foot health. Elevated BMI increases mechanical load on the feet, resulting in excessive plantar pressure, altered biomechanics, and structural deformities that negatively affect mobility and daily functioning. Individuals with obesity are more likely to develop foot-related conditions such as plantar fasciitis, pes planus (flat feet), heel pain, bunions, arthritis, joint stress, and gait abnormalities. Common symptoms associated with increased BMI include persistent foot pain, swelling, stiffness, numbness, fatigue during walking, and impaired balance. Several contributing factors, including sedentary lifestyle, poor footwear, prolonged standing, rapid weight gain, and genetic predisposition, further worsen these conditions. Preventive and management approaches such as maintaining a healthy BMI, engaging in regular physical activity, using supportive footwear and orthotic devices, and participating in physiotherapy and stretching exercises can significantly improve foot function and reduce pain. Maintaining an optimal BMI is therefore essential for preserving foot health, enhancing mobility, and improving overall quality of life.
