MORBID OBESITY

This study tested whether sleeve gastrectomy (a weight-loss surgery) improves walking ability in people with severe obesity. 99 adults with a BMI over 35 or 40 took a 6-minute walk test before surgery and again 6 months after. Researchers also measured quality of life and overall…

This study tested whether a mobile app (Care4Today®) helps people with severe obesity lose more weight before gastric bypass surgery compared to standard care. 142 adults aged 18-65 who qualified for surgery used the app or followed the usual pre-surgery plan. The goal was to see…

This study tested a newer, simpler weight loss surgery called SADI-S against a standard, more complex one (BPD-DS) in 62 adults with severe obesity. The goal was to see if SADI-S is safer and works as well for weight loss and related health problems like diabetes. Researchers mea…

This study tested whether using no opioids during weight-loss surgery (opioid-free anesthesia) works as well as standard opioid-based anesthesia for controlling pain afterward. Sixty adults with severe obesity having laparoscopic bariatric surgery were randomly assigned to one of…

This study tested whether breathing in a mist of dexmedetomidine before surgery could prevent dangerous spikes in heart rate and blood pressure during intubation and the start of laparoscopic bariatric surgery. 90 obese adults (BMI 30-45) took part. The goal was to see if this si…

This study tested whether giving the numbing drug lidocaine continuously through a vein during weight-loss surgery could reduce pain and the need for strong painkillers afterward. 180 adults scheduled for bariatric surgery took part. Researchers measured how much pain medicine th…

This study tested a nerve block called the external oblique intercostal block to manage pain after laparoscopic sleeve gastrectomy in 20 obese patients. The goal was to see how well it numbs the belly area and reduces the need for strong painkillers in the first day after surgery…

This study looked at how physical activity relates to quality of life and mental health in adults with severe obesity (BMI over 40). Participants wore activity monitors for 6 weeks to track their movement and sedentary time. The goal was to understand these connections, not to pr…

This study looked at 725 severely obese adults (BMI 35 or higher) to find the safest way to place a breathing tube during surgery. Researchers compared two methods: one where patients received face mask ventilation during the procedure and one where they did not. The goal was to …

This study looked at how the blood thinner rivaroxaban acts in people with severe obesity and in those who have had weight-loss surgery (gastric bypass or sleeve gastrectomy). 67 participants took rivaroxaban for 8 days, and researchers measured drug levels and blood clotting. Th…

This study looked at 46 people with severe obesity who had either gastric bypass or sleeve gastrectomy. Researchers used a special CT scan with gas to measure stomach volume 3 and 12 months after surgery. The goal was to see if an enlarged stomach pouch is linked to weight regain…

This study examined how the number of meals per day and the timing of calories affect the types of bacteria in the gut. Researchers compared 23 adults with morbid obesity to 11 non-obese adults. No treatment or diet was given—only baseline data was analyzed to understand links be…
