What is a bunion?
A bunion is a bony bump on the joint at the base of the big toe. For some people bunions aren’t bothersome, but for others bunions may cause pain on the surface of the bunion or within connected parts of the foot.
What causes bunions?
Bunions are often formed when the big toe becomes angled toward the other toes. This causes the joint at the base of the big toe to stick out, creating the characteristic bump. Bunions can form when bones and tendons within the foot move incorrectly when supporting weight and eventually become misaligned. It isn’t known exactly why some people develop bunions and others don’t, but it’s likely influenced by multiple factors. Studies suggest that restrictive footwear and genetics may be partially to blame.
Do your genetics impact the likelihood of getting bunions?
