Can you get orthognathic surgery after bariatric surgery?

Your concerns about how bariatric surgery might affect orthognathic surgery are valid. Bariatric surgery can lead to nutrient deficiencies, including calcium and vitamin D, which are crucial for bone health. Since orthognathic surgery involves the repositioning of the jaws and bone healing, adequate calcium levels are important for proper recovery.
However, if you are diligent about your nutrition and supplementation after bariatric surgery, this risk can be mitigated. Many patients who undergo weight loss surgery maintain their bone health through regular monitoring, consistent vitamin intake, and working closely with their healthcare providers.
It would be a good idea to consult both a bariatric surgeon and an oral and maxillofacial surgeon. They can help coordinate a plan to ensure that your nutritional needs are met before, during, and after both surgeries. This proactive approach will maximize your chances of success with both procedures.
