The common feature of these small patients is that they are fat and large. Is a chubby child healthy? This idea is incorrect. With the increasing number of obese children, heart disease, hypertension, diabetes and other age-related diseases are now quietly stalking children, and lumbar disc herniation, an “adult disease”, is also increasingly common among obese adolescents, which requires the attention of parents. Because obese teenagers are heavy and relatively stressed, the chances of a lumbar disc herniation are much higher than in normal weight children. There are three main treatments for lumbar disc herniation: conservative treatment, minimally invasive treatment, and surgery, and different treatments have different indications. Minimally invasive treatment has been accepted by the majority of patients because of the characteristics of no incision, fast recovery, low cost and high safety, and has now become the preferred treatment option for patients with herniated discs. Here, we remind our teenage friends to control their weight, exercise moderately, maintain a good sitting posture and pay attention to strengthening the functional exercise of the lumbar back muscles, which can effectively prevent lumbar disc herniation in teenagers.
