FAQ's Related to Bariatric Surgeon

Bariatric Surgeon help patients to lose weight and to keep the weight off i.e., they assist patients who are obese with weight loss and weight management. Here is a list of some additional positives of weight loss procedures other than being a solution for obesity.:

• Long-term remission for type 2 diabetes • Improved cardiovascular health • Better mental health • Remove sleep apnea • Joint pain relief • Improved fertility

A Bariatric Surgeon help patients lose weight through three kinds of procedures either through ones which somehow lower the intake of food, second ones aim to lessen how much nutrients are absorbed and the third are a combination of both. It is of prime importance that not only do you lose the weight but your lifestyle and diet is an enabler so that you do not gain the weight back and this is also what the surgeon assists you with.

The tests that are to be done prior to and during a Bariatric surgery are listed below for your convenience.:

  • Fe Panel

  • Complete metabolic panel including calcium and liver function tests
  • Homocysteine, C-Reactive protein, lipoprotein a – to assess cardiac risk factors
  • CBC
