The prevalence of overweight and obesity has increased considerably in recent years, causing a worrying condition in people's health and especially in the development of children because it interferes with their physiological development. As a consequence of this overweight, children experience musculoskeletal disorders that mainly affect the lower limbs and feet, with frequent alignment disorders, pain in the hips, knees and feet, increased risk of fractures, reduced joint flexibility and difficulty walking. . The structure and morphology of the foot can be affected by different factors such as age, footwear or body mass index (BMI). Excess body weight can produce morphological changes and collapse ligaments and support structures. Studies have shown larger foot volumes in overweight and obese children, as well as a decrease in the height of the medial longitudinal arch, while children with normal weight have narrower feet. .

There is a direct relationship between an increase in body weight and a greater prevalence of flat feet. On the other hand, flat feet are associated with different conditions, such as the development of bunions or hallux valgus deformities in the adult population. Some authors claim that flat feet and excess weight increase the risk of postoperative recurrence of juvenile hallux valgus.

Excess body weight can contribute to the development or worsening of bunions for several reasons:----

1) Your gait or gait may be altered. The bones in this area are aligned straight, allowing weight to be evenly distributed when walking. However, when you are overweight, the extra pressure on your feet can misalign the toe joint. This causes the big toe to lean toward the other toes, forming a bony protuberance known as a bunion.---

2) Carrying extra weight not only increases the risk of developing bunions but can also exacerbate the pain and discomfort associated with them. The extra pressure on the foot from excess weight can cause the bunion to enlarge and become more uncomfortable over time. Tight or ill-fitting shoes, commonly worn by people with swollen feet due to being overweight, can also worsen bunion pain.------

3) Altered foot mechanics: Carrying extra weight can change the way you walk, potentially altering foot mechanics and increasing the likelihood of developing bunions.---

4) Inflammatory factors: Obesity is associated with chronic low-grade inflammation, which can affect joint health and potentially contribute to the development of bunions.----
