Core Viewpoint - Semaglutide can improve health and slow the aging process, with studies indicating a reduction in mortality rates from various causes, including cardiovascular diseases and COVID-19 [2][4]. Research Background - The prevalence of obesity has led to an increase in obesity-related complications and overall mortality rates. Obesity is an independent risk factor for cardiovascular mortality, making it challenging to reduce obesity-related death rates due to the limited availability of effective interventions [5]. Study Findings - In the SELECT trial, semaglutide significantly reduced all-cause mortality compared to the placebo group, with a 19% reduction in all-cause mortality, a 15% reduction in cardiovascular mortality, and a 23% reduction in non-cardiovascular mortality for overweight or obese patients with cardiovascular disease [10][16]. - Among the deaths recorded, 58% were due to cardiovascular causes, while 42% were non-cardiovascular. The most common causes of cardiovascular death were sudden cardiac death, while infections (including COVID-19) and malignancies were the leading causes of non-cardiovascular death [10][11]. COVID-19 Impact - The use of semaglutide did not reduce the incidence of COVID-19 among patients, but it significantly lowered the mortality rate associated with COVID-19, reducing the risk of death from COVID-19 by one-third [4][15]. The mortality rate for patients using semaglutide was 2.6%, compared to 3.1% for those on placebo [15]. Conclusion - The findings emphasize the benefits of semaglutide in reducing mortality rates among overweight or obese patients with cardiovascular disease. The reduction in non-cardiovascular deaths is primarily attributed to decreased mortality from infections, particularly COVID-19, rather than a general decrease in all non-cardiovascular causes of death [16].

Core Viewpoint - The article discusses the potential effects of GLP-1 receptor agonists, popular weight loss medications, on alcohol consumption and its effects, suggesting that these drugs may reduce the impact of alcohol on the body and decrease drinking desire [5][10]. Summary by Sections What are GLP-1 Drugs? - GLP-1 drugs, such as semaglutide (Ozempic and Wegovy) and tirzepatide (Mounjaro), mimic natural hormones that regulate blood sugar and appetite [7]. Research Findings - A study involving 20 obese adults found that those taking GLP-1 drugs experienced a delayed sensation of intoxication and lower drinking desire compared to those not on the medication. The drugs appeared to slow gastric emptying, which in turn reduced the rate at which alcohol entered the bloodstream [8]. - Participants in the GLP-1 group reported similar levels of nausea and blood sugar changes as the control group, indicating that the reduced intoxication was not due to discomfort [8]. Limitations and Future Research Directions - The study was small and preliminary, lacking random assignment and only involving obese patients. More extensive research is needed to determine the effectiveness, long-term effects, and optimal dosages of these drugs for blood sugar control and alcohol reduction [9]. - Experts caution that the reduced sensation of intoxication could lead to increased alcohol consumption, highlighting the need for future studies to track overall alcohol intake and drinking desires [9]. Potential for Addiction Treatment - Emerging data suggest that GLP-1 drugs may play a role in addiction treatment, as GLP-1 receptors influence reward signals related to food, alcohol, and nicotine. If validated in larger studies, these drugs could bridge the gap between endocrinology and behavioral health [10].
