There is a huge amount of interest among medical researchers in finding a way to maintain weight loss after stopping injectable weight-loss medications. It’s worth noting that similar interest doesn’t exist for any medications we prescribe for other chronic health problems. High cholesterol, for instance. For four decades, we’ve been relying on Lipitor to lower […]

A few posts ago, I discussed the fact that—absent a change—complete weight regain is the usual expectation for those who discontinue treatment with injectable weight-loss medicines. There is huge interest in finding a way to maintain weight loss from Zepbound and Wegovy after the drugs are stopped. Personally, I think maintaining long-term weight loss after stopping the meds will prove impossible. […]

A few posts ago, I discussed the fact that—absent a change— complete weight regain is the usual expectation for those who discontinue treatment with injectable weight-loss medicines. Only a small number of clinical trials involving these meds put in the effort to track patients after the treatment phase ended. The few that did failed to […]

I am asked this question by my patients all the time. The simple, unvarnished truth is that—in the absence of another medical or surgical intervention—people who quit injectables can expect to regain 100% of what they lost. It usually takes eighteen months or so. I don’t blame people for being confused, because you can’t really […]

Does max-dose Wegovy (semaglutide) work as well as weight-loss surgery? In a word: no. Wegovy is a wonderfully effective weight-loss medication — patients who tolerate the max dose lose about 12.5% of body weight on average over a year — but sleeve gastrectomy and gastric bypass patients in Dr. Fitzer’s practice lose 2.6 to 3 times more weight at two years.

I am happy to report that my electronic health record vendor (Baritrax360) updated their app. With one click, I can now pull up my patients’ weight loss data for different operations out to ten years. (Before the change, the report function only gave you five years’ worth of data, which, in my view, is too […]

The bypass-alcoholism connection is worth knowing about. Before I get into it, I should say for the record that my purpose is not to discourage people from considering the gastric bypass. The bypass is a wonderful weight-loss operation. Besides being a safe and fantastically effective treatment for type-2 diabetes and other obesity-related diseases, gastric bypass surgery also results in an amazing 30% to 70% drop in the 10-year all-cause mortality of patients who undergo it compared to patients who could have but didn’t.
