My PCP had not heard of the gastric sleeve either.
She was fairly anti-WLS previously, but has recently changed her mind. Her reason? She has had several patients in the 40-60 age range, that were 100+ pounds overweight just up and DIE in their sleep. She tells me that being so overweight, and being middle aged is a deadly combination. She would prefer that I lose weight without WLS, but, most importantly is to get the weight OFF.
