BMI is associated with increased | ||
Obesity is not just | mortality in individuals who are | |
64 | overweight or obese | |
"too much weight"
- Defined as 'abnormal or excessive fat accumulation that presents a risk to health'.2
- More than 200 complications are linked to obesity -- explains increased, related morbidity and mortality and 4 million related deaths worldwide in 2015.3,4
- QoL of people with obesity or overweight is often impaired and lifespan significantly reduced.5
- High BMI is associated with decreased life expectancy of up to 10 years
- For every 5 kg/m2 BMI increment above the range of 22.5-25.0 kg/m2, overall mortality is increased by 30%.6

Real-World Weight Loss Outcomes for Individuals who are Overweight or Obese Treated with Semaglutide
Patients with T2D experience smaller magnitude of weight loss than those without T2D
Error bars = SD
eHR Mayo Clinic Health System 01/01/2021 to 03/15/2022
Categorical Percentage Weight Loss at 3 and 6 Months (semaglutide)
eHR Mayo Clinic Health System 01/01/2021 to 03/15/2022
Semaglutide delivers similar weight-loss for patients without bariatric surgery, as well as in those with inadequate body weight reduction after bariatric surgery

ALL of Us Research Program Database Version 7, 10,328 new GLP-1RA users. 36.2% were on semaglutide (n = 3739), 29.8% were on dulaglutide (n = 3079), 29.3% were on liraglutide (n = 3031), and 4.6% were on exenatide (n = 479)
FAERS adverse event (AE) reports (between 1 January 2004 and 31 December 2020) were used to investigate the correlation between GLP-1RAs and pancreatic carcinoma. A total of 3073 pancreatic carcinoma cases were related to GLP-1RAs.

Semaglutide-induced weight loss is associated with reduction in muscle mass
Body-weight loss represents combination of a larger loss of fat mass and a smaller loss of muscle mass
Treatment with semaglutide led to significant loss of fat and skeletal muscles (RWE)1
Higher degree of lean mass loss is associated with greater body weight reduction (STEP1)2
Reduction of total lean mass is greater with semaglutide treatment compared to SGLT2i (SUSTAIN8)3
***p< 0.001
From November 2021 to November 2022, a total of 53 patients with obesity (BMI ≥ 28 kg/m2) who received 24 weeks of treatment with semaglutide at the Second Affiliated Hospital of Guangxi Medical University
Loss of muscle mass due to reduced nutritional status is a general physiological response

Medications inducing reduction in the intake of nutrients also bring on reduction in skeletal muscles mass
Medication-induced reduction in nutrition appears to activate general physiological response
