Some causes of foot spurs include straining the foot ligaments and muscles, repeatedly tearing the membrane that covers the heel bone and stretching the plantar fascia, according to WebMD. Risk factors for developing foot spurs include medical conditions such as obesity and diabetes.
Foot spurs are the result of a buildup of calcium deposits on the underside of the heel bone, notes WebMD. They often appear with another condition called plantar fascitis, which occurs when the plantar fascia becomes inflamed. Diabetes is a risk factor for plantar fascitis, while obesity is a risk factor for foot spurs. Other risk factors for these conditions include jogging on hard surfaces and having high arches.
Obesity is a condition that defines a person who has a body mass index of more than 30, explains Healthline. The main cause of developing obesity is consuming more calories than necessary. Lifestyle factors that contribute to obesity include a poor diet, a sedentary lifestyle and lack of sleep. Obesity can also be caused by medical conditions that lead to weight gain, including hypothyroidism, polycystic ovary syndrome and arthritis.
Diabetes is a chronic condition that causes excessively high blood glucose levels. The disease can arise due to a lack of insulin production, defective insulin production or the inability of cells to properly use insulin. Diabetes can lead to serious complications, including hyperglycemia, hypoglycemia and blood vessel diseases that can damage the feet and other parts of the body, notes MedicineNet..
