Ill tell you right now, if your diabetic, get the DS. I too was diabetic, before I left the hospital after my DS surgery my diabetes was cured.
In Europe, the DS is performed on healthy wieght type 2 diabetics soley to treat this disease.
The DS is more invasive, my surgery hurt like hell. But im 7 month, and 135LB lighter. Im a new man, husband, and father.
Any surgery will require you to take supplements afterwards, i just take 1 extra, its not that hard.
The hardest part for me is not eating sugars (gas), or fatty foods (oil slicks).
Like the sleeve, the ghrelin producong portion of your stomach is removed so that benefit is added.
Of all the surgeries, sleeve, bypass, band.... Only the DS cures diabetes. Something like 98.4% cure rate.
Im healthier and happier than I have been in 15 years. Do yourself a favor. Listen to your doctor.
