Popularly known as bunions, hallux valgus is the medical name given to the bone deformity which occurs on the side of the foot, because the metatarsal has deviated. There are many people who suffer from bunions, especially women. They normally cause severe pain that can even prevent the normal development of daily activities. If you want to know what causes bunions, keep reading this OneHowTo article.

Steps to follow:


First, it is necessary to understand how bunions appear, i.e. what causes them. It is because there is a deviation from the bone of the big toe that is part of the instep, known as hallux valgus.

This creates a bulge and that the big toe goes towards the other toes. While not itself a disease, it does cause pain for sufferers, as well as being unsightly.


Thus, you must know that there are different factors which promote the appearance of bunions. On the one hand, there is a series of general factors and on the other extrinsic factors and, finally, intrinsic factors. You may have more than one at a time and, thus, there will be more than one answer as to why you have bunions.


Among the general reasons why bunions appear on the feet, we find:

  • Heredity factors: people whose family members have had bunions are more likely to get this bone malformation.
  • Age: although bunions can also occur at an early age, the most common is that they appear after turning 40 years-old.
  • Gender: women are much more prone to the appearance of bunions, partly due to wearing tight shoes and / or heels.

If we talk about extrinsic factors that answer what causes bunions, we can highlight that the use of tight shoes with a pointed tip, heel, etc. promotes the appearance and development of bunions. That is why women are usually the most affected by this bone deformation.


Similarly, there are underlying causes that can cause or foster the appearance of bunions, such as:

  • Metatarsus primus varus: this involves the separation and internal rotation of the metatarsal bone that leads to the hallux valgus, i.e. the appearance of the bunion.
  • Flatfoot: this other foot condition that affects the arch of the foot is one of the most associated with what causes bunions. That is why it is necessary to go to a podiatrist and know how to treat flat feet.
  • Rheumatoid arthritis: a joint disease that can also cause bunions.
