What Factors Influence a Patient's Success on GLP-1s?
'Treatment responses differ among patients receiving GLP-1 RAs, and the weight fluctuations and associated factors following [their] use have not been adequately characterized,' Linong Ji, MD, of Peking University People's Hospital in Beijing, China, told Medscape Medical News .
The findings, published online in Diabetes, Obesity and Metabolism , 'may provide novel insights into weight fluctuations after GLP-1 RA treatment in a real-world setting,' he said, potentially advancing the development of individualized strategies for patients.
'Corroborates Other Studies'
Researchers conducted a real-world, single-center, retrospective study of 679 patients with overweight or obesity who initiated GLP-1 RA treatment between November 2022 and October 2024.
At baseline, participants had a mean age of 37 years, and 31% were men. The mean BMI was 33.4, and 21% were diagnosed with diabetes.
The GLP-1 RAs used in the study included semaglutide (Ozempic), liraglutide (Victoza), lixisenatide (Lyxumia), beinaglutide (Yishengtai), exenatide (Bydureon), dulaglutide (Trulicity), and PEG-loxenatide (Fulaimei). All were available for participants with both type 2 diabetes (T2D) and overweight/obesity.
For participants with overweight/obesity but without T2D, only Ozempic or Victoza were routinely prescribed, with off-label documentation and informed consent.
Weight measurements were collected during in-person clinic visits, and weight fluctuation curves were stratified into three phenotypes — Successful Weight Reduction, Remaining Stable, and Weight Regain.
Subsequently, the association between potential influencing factors and weight fluctuations was estimated by univariate and multivariate logistic regression. Subgroup analyses were performed in participants with obesity, prediabetes, and in those using liraglutide or semaglutide.
Researchers found significant differences in the duration of GLP-1 RA treatment across groups at the 3-, 6-, and 12-month follow-ups. The Successful Weight Reduction group had a significantly longer duration of GLP-1 RA treatment than the Remaining Stable group and a longer duration at both the 6- and 12-month follow-ups than the Weight Regain group.
Diabetes status also showed group differences. At both the 3- and 6-month follow-ups, the proportion of patients with T2D in the Successful Weight Reduction group was lower than in the Remaining Stable group.
Types of GLP-1 RAs varied between groups, and at the 3- and 6-month follow-ups, the Successful Weight Reduction group was more likely to have initiated treatment with semaglutide than the Remaining Stable group.
Patients with a longer duration of GLP-1 RA treatment (odds ratio [OR], 1.014) and higher Homeostasis Model Assessment of Beta-Cell Function levels (OR, 4.912) were more likely to achieve successful weight reduction at the 12-month follow-up.
Nondiabetic status (OR, 2.176) and using semaglutide (OR, 2.138) were associated with successful weight reduction at the 6-month follow-up.
In addition, a higher percentage of body fat in both men (OR, 3.990) and women (OR, 2.266) was associated with successful weight reduction.
The weight regain group had a higher baseline estimated glomerular filtration rate than the Successful Weight Reduction group and the Remaining Stable group at 3-month follow-up, especially among participants with prediabetes. Ji said this finding surprised him. Patients with obesity often exhibit a state of renal hyperfiltration, characterized by elevated renal plasma flow and glomerular filtration rate, which can be reversed by weight reduction.
The finding suggests that patients with renal hyperfiltration might be less likely to experience durable weight reduction, Ji said. 'However, few studies have revealed similar observations. Therefore, further validations and investigations are still needed for this finding.'
Furthermore, the team found a positive nonlinear association of serum creatinine with successful weight reduction at 12 months — a finding that will also require additional investigations to examine the mechanism underlying the association.
Overall, Ji concluded that while longer duration of GLP-1 RA treatment using semaglutide, nondiabetic status, and higher percentage of body fat might be associated with better weight reduction, 'basal metabolic rate, skeletal muscle mass, muscle mass of the abdomen and limbs, and serum creatinine were nonlinearly associated with the probability of successful weight reduction.'
Randy Seeley, MD, Henry King Ransom Endowed Professor of Surgery, Internal Medicine, and Nutritional Sciences at the University of Michigan School of Medicine, Ann Arbor, Michigan, and director of the National Institutes of Health-funded Michigan Nutrition Obesity Research Center, told Medscape Medical News , 'The main results of the study agree with what the field has already seen. Although it is a relatively small study, it corroborates other larger studies,' said Seeley, who was not involved in the study.
This work was supported by the Noncommunicable Chronic Diseases-National Science and Technology Major Project. Ji reported receiving fees for lecture presentations and for consulting from AstraZeneca, Merck, Metabasis, MSD, Novartis, Eli Lilly and Company, Roche, Sanofi-Aventis, and Takeda. Seeley reported that his lab has worked with both Novo and Lilly (and others trying to enter the space), and he has also served as a paid consultant for both of those companies (and others trying to enter the space).

Suicide crisis in South Korea: Nearly 10 aged 65+ take own lives each day
SEOUL, Aug 3 — Nearly 10 South Koreans aged 65 and above died by suicide each day between 2019 and 2023, according to a new medical study in the Journal of the Korean Medical Association. A total of 18,044 people in that age group took their own lives during the five-year period; this works out to more than 3,000 deaths every year, The Korea Herald reported today. The study was authored by Dr Oh Dae-jong, assistant professor of the Workplace Mental Health Institute at Kangbuk Samsung Hospital and the Seoul Metropolitan Government. According to the study, the suicide mortality rate among South Koreans aged 65 and older stood at 40.6 per 100,000 in 2023. This was 45 per cent higher than the rate of 28 recorded among those aged 15 to 64. 'Older adults are less likely than younger people to seek psychiatric help before attempting suicide, and many take their own lives after only one or a few attempts, making early identification of high-risk seniors important,' Dr Oh was quoted as saying in the study. Depression in South Koreans aged 65 and above is often linked to the loss of a spouse, financial stress, loneliness, family conflict and feeling like a burden to their families, the study noted. Chronic physical illness is another major factor, especially in the period soon after a diagnosis. Compared to younger people, those aged 65 and above are more likely to use fatal methods such as ingesting pesticides or hanging, which makes survival much less likely. The South Korean study advised on the need to train 'gatekeepers across the medical field who can identify and respond to early verbal, emotional and behavioral warning signs in older adults at risk of suicide'. It also recommended comprehensive, collaborative strategy between health professionals and the community to prevent more suicides. Statistics Korea said the population of people aged 65 and older crossed the 10 million mark for the first time in November last year. There were 10.12 million in that age group, an increase of 513,000 from the year before. People aged 65 and above now make up 19.5 per cent of South Korea's total population of 51.81 million. This means nearly one in five South Koreans are now 65 or older. * If you are lonely, distressed, or having negative thoughts, Befrienders offers free and confidential support 24 hours a day.

The Best Tea to Help Lower Cholesterol, According to Dietitians
Key Points Green tea contains catechins—antioxidants that may help lower LDL and total cholesterol levels. Some studies link green tea to modest drops in cholesterol levels, though results vary. Tea can be part of a heart-smart routine—just avoid added sugar and consult a healthcare professional you have high cholesterol, you're likely turning to your diet to make changes to help keep your cholesterol in check. Maybe you've have heard that upping fiber and reducing saturated fat and added sugar can positively affect cholesterol levels. Still, you may not have heard of one beverage that may also have a beneficial effect—tea. 'Traditional tea contains antioxidants and offers health benefits such as cancer prevention and cholesterol reduction,' says Lisa Andrews, M.E.d., RD, LD. Because of this, it can be a healthful addition to most diets. Why Green Tea Is So Great for Lowering Cholesterol Green tea may be one of the most beneficial teas when it comes to the potential for lowering cholesterol levels. Green tea, along with other types of tea, is a source of various types of polyphenols. 'The polyphenols in the tea leaves provide antioxidants,' says Wan Na Chun, M.P.H., RD, CPT. Some studies have found a connection between green tea consumption and a slight reduction in LDL cholesterol. Other studies have looked specifically at cholesterol levels in populations with other chronic conditions and have found a benefit when adding green tea to the diet. More specifically, a small study found that people with type 2 diabetes and nephropathy (kidney disease) who drank three cups of green tea per day had a reduction in total cholesterol. The tea was consumed before a meal, and other factors in the diet were not controlled, so it's impossible to know if the tea alone impacted cholesterol or if other dietary changes positively affected cholesterol. Still, the results are promising for green tea's potential impact on total cholesterol. A meta-analysis found similar results. This review found that consuming green tea may significantly help lower both total and LDL cholesterol (also known as 'bad' cholesterol). However, this study also had limitations, including not determining the amount of green tea needed to influence cholesterol levels. Brooke Baird, RDN, says the optimal amount of tea required to help lower cholesterol levels is not clearly defined. 'It can vary depending on individual factors such as age, health status and overall diet and lifestyle,' says Baird. It's also important to note that many studies investigating the effect of green tea on cholesterol use a mix of green tea extract and green tea as a beverage. However, most of the studies are looking at the catechin concentration, which is the compound thought to have the most significant impact on cholesterol levels. Catechins are flavonoids (a type of antioxidant) found in green tea. One of the most well-known catechins in green tea is EGCG. 'Epigallocatechin gallate (EGCG) has been heavily researched and shown to be very effective in decreasing cholesterol,' says Umo Callins, M.S., RD, LD, CSSD, CPT. Green tea's effect on lipid levels is thought to be multifaceted. In addition to preventing oxidation of LDL, which leads to plaque formation in your arteries, 'Studies show green tea may significantly inhibit lipid absorption in the intestine, which is beneficial for lowering cholesterol,' says Chun. More Research Is Needed While drinking tea, particularly green tea, may be beneficial for lowering cholesterol levels, more research is still needed. 'The FDA has not approved any health claims for green tea beverages to reduce cardiovascular disease risk,' says Chun. It is best to consult a healthcare professional before using tea to help manage high cholesterol, adds Chun. Tea also contains caffeine, which can have adverse side effects when consumed excessively. 'Drinking excessive amounts of caffeinated tea could lead to side effects like headaches, insomnia, irritability, dizziness and anxiety,' says Chun. Excess caffeine intake can also lead to gastrointestinal symptoms in some cases. However, green tea's total caffeine content is lower than that of other caffeinated beverages like coffee. For reference, one cup of green tea contains around 30 milligrams of caffeine, compared to 100 mg in a traditional cup of coffee. Other teas, particularly ones made of herbs, may also have unintended side effects. 'Herbal teas can interfere with some medications like blood thinners, anti-inflammatories, anti-seizure drugs, aspirin, blood pressure medications and diabetes treatments,' says Chun. It's important to review your medications and any supplements or teas with a healthcare professional. Safety Tips and Best Practices If you plan to add green tea to your daily routine, then it's best to do so in a way that will help you increase the healthfulness of your diet as a whole. Avoid green tea with excess added sugar, which can negatively impact your overall health. Choosing a high-quality tea from a reputable company that tests for pesticides and other contaminants is also important. Many companies will provide their testing procedures on their website or will provide a Certificate of Analysis upon request. You can also look for companies that follow Current Good Manufacturing Practices (cGMP) to ensure quality. Our Expert Take Tea can be a delicious, health-promoting beverage to add to your diet. Choosing tea, especially green tea, may have a beneficial effect on total cholesterol. However, it's best to avoid drinking tea with added sugar to reap the greatest benefit. 'While tea can be a part of a healthy lifestyle, it's essential to consume it as part of a balanced diet and lifestyle,' says Callins. 'Consult with a health care professional if you have any concerns or underlying health conditions.' Read the original article on EATINGWELL

Does acupressure help you sleep better? I asked two experts — this is what they said
When you buy through links on our articles, Future and its syndication partners may earn a commission. In a time where we're bombarded with social media trends for sleep like April Theory and the 'sleepy girl mocktail,' it can be easy to forget that there are some methods you can use to help with your slumber that have been around for thousands of years. Like acupressure, a non-invasive, ancient traditional Chinese medicine practice that involves the use of pressure on the face and body at certain points, some of which are used to help with sleep. Research has shown that acupressure can help with sleep, from reducing insomnia, to improving sleep quality in hospital patients and even contributing to better sleep in menopausal women. Here, we'll explore this research and the potential benefits of acupressure for sleep, as well as speaking to experts in the field to find out about what acupressure is, and how you can even practice it in the comfort of your own home. What is acupressure and how does it work? "Acupressure is a non-invasive traditional Chinese medicine technique that uses pressure on the face and body at specific points known as acupoints," says registered acupuncturist Lily Lai, who has a PhD in Chinese Medicine in Primary Care and offers acupressure at her UK clinic. "Pressure is applied in a variety of ways – most commonly finger pressure is used as well as tools," she adds. Doctor of Oriental Medicine (DOM), Dr. Haley Parker, who is a licensed acupuncturist and the Director of Clinical Operations at VUIM Clinic (Virginia University of Integrative Medicine), explains that in acupressure, gentle sustained pressure is applied to "specific points along the body's meridians — energy channels that correspond to organs and systems." "It's based on the same principles as acupuncture, but instead of using needles, you use fingers, palms, elbows, or tools to stimulate the points," Dr. Parker explains. "The idea is to restore the smooth flow of Qi (vital energy) and blood through the body to promote healing, reduce tension, and support balance between the body and mind," she says. "From a Western perspective, acupressure may stimulate the nervous system, influence endorphin release, reduce cortisol, and activate the parasympathetic 'rest and digest' response," the doctor continues. According to The American Institute of Alternative Medicine, the practice is "based on the belief that applying firm pressure in specific acupoints stimulates the nervous system and brain to release endorphins and neurotransmitters to ease... pain." Acupressure falls under what the National Health Service (NHS) in the UK describes as 'complimentary and alternative medicine' (CAM) and they do advise that "if you think you may have a health condition, first see your GP. Do not visit a CAM practitioner instead of seeing your GP." Is there any science proving acupressure improves sleep? As the NHS points out, it is important to review the evidence when considering a complimentary or alternative medicine. When it comes to acupressure there is "a growing body of evidence supporting [its] effectiveness for sleep," says Dr. Parker. As well as the research cited below, a review of studies into the effect of acupressure on hospital inpatients showed that it improved factors such as sleep quality, total sleep time, sleep efficiency and sleep onset latency compared to control groups. Researchers concluded that it is an "effective intervention to improve sleep quality and sleep parameters in inpatients." Among the studies she highlighted, Dr. Parker pointed to a review of studies and a specific study which both showed that acupressure improved sleep quality in older people. How can acupressure benefit sleep? 1. Stimulate specific pressure points As we've explored above, this traditional Chinese medicine practice involves applying pressure to certain points. Dr. Parker says it can support sleep "by calming the nervous system, easing physical tension, and regulating the underlying organ systems that influence rest." She notes that the best combination of acupressure points for sleep depends on what the individual is experiencing and that a personal point prescription would then be selected to "to support the patient and the present symptoms, like insomnia and restlessness." However, she shares the following common points and how they work from a traditional Chinese medicine perspective: "Shenmen (HT7 – Heart 7): Located on the wrist crease, this point is often used for insomnia, anxiety and emotional restlessness. It calms the Shen (spirit), helping to settle racing thoughts and reduce overactivity of the Heart system, which in TCM can disturb sleep." "Yintang ('Third Eye'): Found between the eyebrows, this point is deeply calming and is known to relieve stress, quiet the mind and support melatonin production through relaxation of the pineal and hypothalamic areas." "Anmian ('Peaceful Sleep'): A lesser-known but effective point located behind the ear, Anmian is used specifically for sleep disturbances, helping to ground the nervous system and encourage deeper, more sustained rest." "Sanyinjiao (SP6 – Spleen 6): Located on the inner lower leg, this point supports hormonal regulation and helps harmonize the Spleen, Liver, and Kidney systems. These organs play key roles in emotional regulation and sleep according to TCM." 2. Reduces stress and anxiety Anxiety can mean that worries, racing thoughts and restlessness make it particularly hard to fall asleep. Lai says that one of the common causes of sleeplessness is stress and anxiety, and points to a systematic review and meta-analysis of research which showed acupressure can significantly reduce anxiety. Acupressure can significantly reduce anxiety "Studies suggest that acupressure and acupuncture work in similar ways by encouraging the body to release neurotransmitters such as endorphins and serotonin," says Dr. Parker. "both of which are mood elevators and play a major role in sleepregulation via the hypothalamic-pituitary-adrenal (HPA) axis," she explains. "Acupressure may also be increasing parasympathetic nervous activity, the rest-and-digest part of our nervous system which takes the body away from being in the sympathetic nervous system state, the fight-or-flight response," Lai adds. She says that these calming, anxiety-reducing effects of acupressure can help sleep by improving both sleep latency, and sleep duration. 2. Helps to ease insomnia Those who have experienced either short-term (several days or weeks) or chronic insomnia (lasting three months or more), know that it doesn't just interfere with your sleep. It can also cause issues including irritability, fatigue and problems with focus the next day. But research shows that acupressure may be a tool you can include to combat it. One study compared the effect of acupressure on those with insomnia, with 200 participants divided into a group who were taught self-administered acupressure, and a group who were given sleep hygiene education. They found that those who had learned acupressure had improved Insomnia Severity Index scores after both four weeks and eight weeks, compared to the other group. Auricular acupressure, which focuses on pressure points on the ear, has been shown in a number of studies to help with insomnia. One review of studies looking at how effective auricular acupressure is as a treatment for insomnia concluded that, "the effects of auricular acupressure on insomnia are comparable to those of estazolam," which is a medication used short-term for treating insomnia. And while Dr. Parker noted above that acupressure be used to help with sleep issues like insomnia, she also explains that, "lack of sleep/insomnia is often a symptom of an underlying imbalance." "There are also lifestyle factors and habits that should be addressed to support a restful nights sleep (examples include limiting screen time before bed, limit caffeine after 3pm in the afternoon, eliminate noises and lights in the bedroom, try to go to bed at a regular time each night etc)," she explains. 3. Can help with hormonal changes affecting sleep "Sleep problems can also be associated with hormonal changes and studies have demonstrated that acupressure can be effective for improving sleep in these patient populations," says Lai. A huge number of women experiencing menopause have issues with their sleep. In fact, 2023 research noted that across the world, sleep and menopause effects the lives of about a third of women. Lai suggests that acupressure may be one way to help tackle this, explaining that, "acupressure has shown in recent trials to significantly improve sleep quality in menopausal women." A trial published in the Iranian Journal of Medical Sciences, found that "acupressure alone can improve sleep quality at a rate of 22% in menopausal women by massage on the effective points," and concluded that it "can be used as a complementary treatment to relieve sleep disorders in menopausal women." In addition, Lai says that "Studies have indicated that acupressure impacts hormone-related sleep problems through decreasing levels of follicle stimulating hormone (FSH) as well as through increasing levels of oestradiol." "These in turn improve sleep quality related to hormonal conditions, but also in other symptoms such as hot flushes and fatigue," she explains. How to try acupressure for sleep at home If you're interested in exploring acupressure and want some simple options that you can try out from the ease of your home, Dr. Parker suggests the following. "Finger pressure massage: Apply gentle, circular pressure to key points like HT7 (wrist), Yintang (forehead), or SP6 (inner leg) for 1–2 minutes each, preferably in the evening before bed." "Acupressure mats: These mats use small spikes to stimulate multiple points along the back and shoulders. Lying on one for 10–20 minutes can help reduce muscular tension and promote parasympathetic nervous system activation—ideal for winding down." "Partner massage: Light massage focusing on the neck, shoulders, and feet can activate calming points. Adding lavender oil or calming music can enhance the effect." "Breathing with pressure: Combine acupressure with slow, deep breathing to amplify relaxation. Inhale deeply, press a calming point (like Yintang), and exhale slowly." Acupressure mats like the Shakti mat and Pranamat have become popular options to try at home, and both promise to help improve your sleep after just 20 minutes use. Pranamat even cites stats from Dr. Marek Dvořák's sleep tracker, which show that after using the Pranamat 20 minutes before sleep, his REM sleep increased by 2%, deep sleep increased by 7% and light sleep was reduced by 10%. Lai also shares the one piece of advice given to every patient in her practice experiencing sleep issues: "Utilise acupressure wristbands to stimulate Nei Guan (Pericardium 6). Whilst this acupoint is widely known for nausea and vomiting, it is also used frequently in traditional acupuncture for sleeplessness as well as for stress and anxiety," she says. This pressure point is found between the two tendons ont he inner aspect of the forearm, three finger widths below the wrist crease. Is acupressure suitable for everyone? It's important to consult your doctor if you are experiencing pain or a medical condition, however, Lai and Dr. Parker agree that acupressure is, in general, very safe for most people. "Basic self-acupressure can be safely carried out in specific circumstances such as with acupressure wristbands for nausea and vomiting," Lai says. But she notes that, "for face, body or ear acupuncture and for more complex conditions, this is safest and most effective when carried out by a TCM practitioner who is registered with an appropriate acupuncture professional body." "If you are actively under the care of a doctor or consultant for a medical condition, you should always seek their advice prior to using acupressure," she explains. It's important that certain patient groups such as children, pregnant women and the elderly should check with their doctor before using acupressure for their health concerns.
