Reasons for Musculoskeletal disorders in obese people: 
In people who are obese, excessive weight applied to the joints and bones in high pressure points such as the back, knees and ankles causes corrosion and wear (arthritis) and slippage of these joints.
In addition, with the increase in the size of the belly, the Gravity Center of the body changes and over time, with increasing pressure in the spine, it will cause deformities and various injuries of the spine and spinal cord, and even short stature.
Inflammatory substances in fats (lepton) act as toxins for joints and can lead to joint rheumatism.
On the other hand, people who are obese and overweight have a much lower amount of vitamin D than people with normal weight, which happens due to retention of vitamin D in excess fat tissue and leads to severe osteoporosis.
Obese people suffer from ankle sprains more than normal weight people, which causes more weakness of ankle tendons and ligaments.

By reducing the weight, the pressure on the high pressure points of the body such as knees, ankles and back is reduced and the wear of the joints is reduced.


The effect of weight loss on knee arthritis
According to studies and reviews, weight loss of 5 kg can reduce the probability of knee arthritis by 50%. 

Bone health after bariatric surgery: 

Is it possible to develop Musculoskeletal disorders  after bariatric surgery?

 

Bariatric surgery is an effective treatment for morbid obesity and its accompanying complications. But due to factors such as rapid weight loss and reduced absorption of nutrients, patients may be at risk of developing metabolic bone disease.

Patients who undergo Malabsorptive surgical procedures are more exposed to bone health problems after bariatric surgery than patients who undergo restrictive procedures.

Consequently, preventive strategies and nutritional care may be necessary to reduce bone loss after bariatric surgery.

Overall, despite the known advances in obesity-related diseases, increasing evidence suggests that bariatric surgery contributes to the onset of adverse skeletal health outcomes.

A multifactorial clinical management approach including regular BMD assessment (bone mineral density test) is recommended for the prevention of osteoporosis after bariatric surgery.

A bone mineral density (BMD) test is the best way to measure your bone health. This test can show if you have osteoporosis or not.

 

Prevention of osteoporosis after weight loss surgery
Factors that can prevent osteoporosis after bariatric surgery include:

Calcium Intake :
Adequate intake of vitamin D and protein in the diet.
Doing regular exercise as prescribed by the doctor.
The data obtained in the studies show that following the bariatric surgeon's recommendations regarding diet and especially the consumption of supplements and minerals as well as doing exercises play an important role in minimizing bone and Musculoskeletal disorders post surgery.
