What causes bunions?
The exact cause of bunions is not known, but there are a few factors that increase the chance of developing them. Genetics is the most common reason behind bunions, so if someone in your family has bunions, it is likely that you will develop them as well. Footwear plays a big role in the formation of bunions. Ill-fitting shoes, like shoes that are too tight or too high-heeled can put too much pressure on the toe joint, leading to bunions.
Footwear that is too loose, like flip flops, can also cause bunions by allowing the foot to roll inward. Bunions can also be caused by medical conditions such as arthritis. Arthritis can cause the joint to become inflamed and the bones to become misaligned.
