It’s probably fair to say that most people would like to be thinner. More than 42% of Americans have obesity and another 30% are classified as being overweight, according to the latest statistics from the CDC.
Dr. Dinah Miller
Excess body weight is associated with many illnesses and plays a role in mental health; being heavy can take a toll on self-esteem. Many people worry that carrying excess weight makes them less attractive to potential romantic partners, and both physicians and employers treat those with obesity differently. Furthermore, in psychiatry, many of the medications we prescribe lead to weight gain.
In my clinical practice, I have listened as patients blamed themselves for their body habitus; many won’t consider biological treatments as they feel that would be “cheating” or taking an easy way out. They often point to periods in their life when they did lose weight and believe that they should be able to do it again, even if the weight loss took tremendous effort, was not sustained, and occurred decades ago.
That said, we psychiatrists often find ourselves in the position of managing obesity in our patients. I have been known to give patients who gain weight on antipsychotics either stimulants or metformin, or to add naltrexone to their Wellbutrin (bupropion) to effectively mimic a weight-loss medicine called Contrave.
Obesity a treatable medical condition
It wasn’t until 2013 that the American Medical Association recognized obesity as a medical condition.
In a New Yorker article that same year, “Diet Drugs Work: Why Won’t Doctors Prescribe Them?” Suzanne Koven wrote: “Several obesity experts told me they’ve encountered doctors who confide that they just didn’t like fat people and don’t enjoy taking care of them. Even doctors who treat obese patients feel stigmatized: ‘diet doctor’ is not a flattering term.”
Eat less, exercise more – with a blame-the-patient attitude – is still what people see as the “right” way to lose weight.
On June 4, 2021, the FDA approved semaglutide, a glucagonlike peptide–1 receptor agonist, previously used for the treatment of diabetes, for use as a weight loss agent for patients with obesity, or for those with a body mass index over 27 kg/m2 if they also have a weight-related comorbidity.
Semaglutide has three trade names, all manufactured by Novo Nordisk. The pill version is called Rybelsus and comes in 7-mg and 14-mg tablets. Ozempic is available in 0.5-mg and 1.0-mg doses and is administered weekly by subcutaneous injection for diabetes. The new, higher-dose preparation for weight loss, Wegovy, 2.4 mg, also comes as a weekly subcutaneous dose and is now available for the hefty price of $1,400 per month.
In STEP 1 trials, the higher-dose Wegovy was associated with an average 14.9% weight loss (15.3 kg) over 68 weeks, more than any other single-agent weight loss medication on the market.
GLP-1 receptor agonists work in the brain to decrease appetite, slow gastric emptying, increase insulin secretion, and stimulate brown adipose tissue thermogenesis.
