OCC’s epidemiologist is closely monitoring the COVID-19 status and is actively issuing updates as they are available. The Centers for Disease Control and the World Health Organization are the most trusted sources online.  While the CDC has announced new mask protocols for vaccinated individuals, there will be no changes for our office protocols for patients, guests, and staff members as the announcement does not apply to hospitals or medical facilities. Masks are still a requirement for all patients, guests and staff at our facility.

As we reinitiate weight loss surgery, we are constantly adapting and installing new and updated safety measures.

Weight loss surgery is medically necessary.

Bariatric Surgery and the clash of two pandemics.   

Major metabolic and bariatric surgery Societies and colleges globally are now calling for the safe resumption of bariatric and metabolic surgery before the COVID-19 pandemic is declared over. 

The sooner bariatric surgery can be safely performed, the quicker obesity, type 2 diabetes, and other diseases can be reduced or resolved as they are not only chronic they are also progressive.  Obesity is also linked to more than 40 diseases including type 2 diabetes, hypertension, heart disease, stroke, sleep apnea, osteoarthritis, and at least 13 different types of cancer.

A recent statement from the ASMBS says “Before COVID-19 began, it was clear that patients with obesity were ‘safer through surgery.’ In the era of COVID-19, ‘safer through surgery’ for patients with obesity may prove to be even more important than before.” Obesity and Metabolic syndrome have been identified as an independent risk factor for adverse outcomes including death among COVID-19 patients.
