有研究证实超重或肥胖是足底筋膜炎发病的危险因素。
体重指数达25kg/m^2发病风险提高一倍;体重指数达30kg/m^2,发病风险为普通人群的5.6倍。[12]Riddle DL, Schappert SM.

体重指数不仅仅是足底筋膜炎发病的风险因素,也与患者的功能受限相关。[12]Riddle DL, Schappert SM. Volume of ambulatory care visits and patterns of care for patients diagnosed with plantar fasciitis: a national study of medical doctors.

体重对于手术治疗成功与否影响不大。超重患者与体重正常患者手术治疗成功率相近。
