When Ozempic And Wegovy Fail To Work- Why GLP-1 Drugs Aren’t The Magic Bullet For Everyone
Ozempic and Wegovy have received a lot of publicity as revolutionizing treatment options for obesity. Both medications form a class of GLP-1 receptor agonists, which mimic a hormone in the body called glucagon-like peptide-1 and are involved in the regulation of appetite and blood sugar. Indeed, in initial clinical studies, the majority of those on the drugs lost 15% to 22% of body weight, hence much optimism. For most patients, these medications are underwhelming for about 20% of patients due to minimal weight loss or other challenges.
Take a closer look at why the weight loss drugs may not work for everyone, together with what options exist when they don't deliver the expected outcomes.
While GLP-1 receptor agonists have produced phenomenal responses in a majority of patients, it remains a reality that these drugs work differently for different people. Here's why:
1. Genetic and Hormonal Variability
Weight loss medications interact with complex systems in the body that differ from person to person. Genetics, hormones, and individual brain responses to energy regulation play significant roles in determining how a person responds to drugs like Ozempic and Wegovy.
2. Underlying Medical Conditions
Other conditions, such as sleep apnea, may be prevalent and prevent or delay the achievement of weight loss goals. Prescription drugs like antidepressants, steroids, or contraceptives are other medications that can nullify weight loss medication benefits.
3. Unrealistic Expectations
Often, they come to these medications with enormous hopes; expecting the promised rapid and dramatic weight loss. Progress creates disappointment if it has not stalled. In patients who rigidly follow recommended lifestyle modifications, frustration and disappointment are most common.
For most patients, the effectiveness of GLP-1 receptor agonists is evident within a few weeks of treatment. Weight loss typically begins within a few weeks of initiating therapy and tends to increase with dosage. However, some patients respond very little, if at all, despite strict adherence to their regimen.
For nonresponders, this can feel like a dead end. However, understanding the unique complexities of obesity is essential. This condition stems from brain dysfunction, and the pathways that contribute to weight regulation differ among individuals.
When Ozempic or Wegovy doesn’t yield desired results, there are still many paths to explore:
For example, some patients who don't respond well to one GLP-1 receptor agonist might find success with another drug in the same class. Newer medications, such as Zepbound, target other hormone pathways and seem promising even for those not responsive to earlier drugs.
While there is much to say about newer drugs, older treatments can still be useful and work for some patients. One can also seek the help of a medical provider specializing in obesity treatments in order to identify the best alternatives.
Diet, exercise, sleep, and stress management continue to be integral components of any weight loss program. New changes may be small but can make an enormous difference in one's health and success.
It is a complex disorder, and most patients should receive a multidisciplinary treatment. Collaboration with an obesity-aware doctor may mean access to tailored treatment plans, ranging from psychological support all the way to metabolic testing, and many others.
For others, side effects like nausea, vomiting, or diarrhea hinder them from continuing with these drugs. These symptoms often reduce as the body becomes accustomed, but for some, they might be severe enough to stop treatment altogether. In those instances, alternative drugs or procedures become vital to find.
Another largely unexplored area relates to GLP-1 drugs' long-term effects on the brain's regulation of hunger and satiety. Although GLP-1 drugs suppress appetite and can lead to effective weight loss, emerging research suggests that they may also affect brain reward mechanisms, changing the way patients experience foods.
This aspect could prove of paramount significance in the future treatment of obesity. Perhaps GLP-1 receptor agonists do indeed affect and rewire the brain's reward pathways and will thus provide sustained benefits beyond discontinuation. However, more research is required to understand this phenomenon fully.
While for many, Ozempic and Wegovy have revolutionized obesity treatment, these are certainly not a one size fits all. Nonresponders need not lose hope- alternative strategies and medications abound. A consultation with an obesity expert healthcare provider is essential to put together a comprehensive, tailored treatment plan.
The route toward effective weight loss may be challenging, but with the evolution of obesity medicine and a better understanding of individual needs, there is a path forward for everyone.

A new study published in the Journal of the American Chemical Society offers critical insight into the biological mechanisms underlying type 2 diabetes. Researchers from the Indian Institute of Technology Bombay (IIT Bombay), in collaboration with IIT Kanpur and the Chittaranjan National Cancer Institute (CNCI), Kolkata, have identified a key trigger that accelerates the progression of this widespread disease: the structural protein collagen I.
Type 2 diabetes currently affects over 500 million people worldwide, and numbers are expected to rise sharply in the coming decades. The disease is primarily driven by a combination of genetics, lifestyle factors, and complex cellular mechanisms. At its core lies the dysfunction of pancreatic β-cells, the insulin-producing cells responsible for regulating blood sugar levels.
As diabetes develops, β-cells either fail to produce enough insulin or the body’s cells become resistant to it. A lesser-known yet crucial hormone, amylin, is also secreted by these β-cells and plays a vital role in managing blood sugar after meals. However, in diabetic conditions, excessive amylin production leads to misfolding and toxic clumping, which damages β-cells and accelerates disease progression.
In the latest study, the research team pinpointed fibrillar collagen I, a common component of the extracellular matrix, as a key factor driving the toxic aggregation of amylin. Found abundantly in connective tissues like skin and bones, collagen I is also present in the pancreatic environment—particularly in diabetic tissues where it is elevated.
“Every tissue is composed of cells and an extracellular matrix that provides structural support. In diabetic pancreatic tissue, this matrix, especially collagen I, becomes more prominent,” explained Prof. Shamik Sen, the study’s lead investigator from the Department of Biosciences and Bioengineering at IIT Bombay.
The researchers discovered that collagen I acts like a scaffold or platform, accelerating the misfolding and aggregation of amylin, which in turn damages β-cells. This discovery adds a new layer to understanding why the disease worsens over time, even with treatments targeting cellular pathways.
To investigate how collagen I interacts with amylin, the team used a suite of advanced biophysical tools. These included surface plasmon resonance to measure binding strength, atomic force microscopy to study molecular adhesion, thioflavin T fluorescence to track aggregation speed, and NMR spectroscopy to identify interacting regions of the molecules.
“Amylin almost coats the collagen fibres, forming stable, toxic aggregates that cells struggle to clear,” said Prof. Sen. The behavior of amylin on collagen fibres resembled trains moving on tracks—quickly and with destructive momentum.
Computer simulations by Prof. Prasenjit Bhaumik’s group at IIT Bombay confirmed that fibrillar collagen I accelerates the toxic aggregation process, offering further validation of the molecular interaction.
The team extended their study to biological samples from diabetic mice and humans. With the help of Prof. Hamim Zafar and Prof. Sai Prasad Pydi from IIT Kanpur, and Dr. Sankhadeep Dutta from CNCI, they analyzed single-cell data and tissue architecture.
The findings were striking: as diabetes progressed, both collagen and amylin levels rose, accompanied by damage to pancreatic islets—clusters of cells that house insulin-producing β-cells.
To test the functional impact, the researchers grew lab-engineered β-cells on collagen gels containing amylin. These cells showed increased oxidative stress, reduced insulin production, and higher rates of cell death, compared to controls grown without collagen or amylin.
This suggests that the extracellular environment, particularly collagen I, plays a central role in worsening β-cell dysfunction in diabetes.
The findings could explain why many diabetes treatments fall short—they overlook the external microenvironment contributing to disease progression. “Unless we disrupt the interaction between amylin and collagen, we may not be able to eliminate the toxic pancreatic environment,” said Prof. Sen.
Looking ahead, the team is working on cryo-electron microscopy (cryo-EM) models to visualize how amylin and collagen interact at the molecular level. They are also exploring 3D tissue engineering strategies to restore pancreatic function by replicating healthy extracellular conditions.

As wildfires become an all-too-familiar headline across the globe, their visible devastation—scorched forests, lost homes, and displaced communities—often overshadows a more insidious threat: the impact of wildfire smoke on human health. While the immediate dangers of flames and evacuations are clear, a new study published in Nature Medicine reveals that wildfire smoke does far more than irritate eyes and throats. It can fundamentally alter the immune system, potentially making people more susceptible to illness long after the smoke has cleared.
The study, led by researchers from the Harvard T.H. Chan School of Public Health, found that people exposed to wildfire smoke exhibit changes in gene expression and immune function, even if they’re otherwise healthy. This suggests that the health consequences of wildfires may extend far beyond the immediate coughing, wheezing, and watery eyes that so many experience during fire season.
The research, led by Dr. Kari Nadeau of the Harvard T.H. Chan School of Public Health, provides the most detailed look yet at how wildfire smoke affects the body on a cellular level. By analyzing blood samples from 31 firefighters and civilians exposed to wildfire smoke and comparing them to 29 unexposed individuals, the study uncovered a complex web of immune changes.
People exposed to wildfire smoke showed a marked increase in memory immune cells—cells that typically provide long-term immunity. At first glance, this might seem beneficial, but the study also found elevated biomarkers of inflammation and immune activity, as well as changes in dozens of genes linked to allergies and asthma. In short, the immune system was not just activated—it was thrown into overdrive, potentially increasing vulnerability to illness.
Dr. Mary Johnson, the study’s lead researcher, explains, “Our findings demonstrate that the immune system is extremely sensitive to environmental exposures like fire smoke, even in healthy individuals. Knowing exactly how may help us detect immune dysfunction from smoke exposure earlier and could pave the way for new therapeutics to mitigate, or prevent altogether, the health effects of smoke exposure and environmental contaminants.”
Wildfire smoke is a toxic brew. It contains:
The ultra-fine PM2.5 particles are particularly dangerous. At less than 2.5 micrometers in diameter, they are 28 times smaller than the width of a human hair and can be inhaled deep into the lungs, enter the bloodstream, and affect organs throughout the body.
“These findings suggest that even short-term exposure to wildfire smoke can act as a biological stressor with long-lasting effects,” said Dr. Mary Johnson, lead researcher and environmental health scientist at Harvard. “That’s especially concerning as wildfire seasons grow longer and smoke plumes travel farther.”
One of the most striking findings of the study was the alteration of 133 genes related to allergies and asthma in those exposed to wildfire smoke. This genetic shift may help explain why people living in wildfire-prone areas often report more respiratory problems, even months after the fires have ended.
The study also found that smoke-exposed individuals had more immune cells affected by toxic metals, further increasing inflammation and the risk of immune dysfunction. These changes may make people more susceptible to infections, worsen existing respiratory conditions, and potentially contribute to the development of new allergies or asthma.
The United States, particularly western states like California, has witnessed a dramatic increase in wildfire frequency and severity. In 2023 alone, California experienced over 7,000 wildfires, with the California Department of Forestry and Fire Protection responding to nearly 590,000 related emergencies. The devastating January 2025 fire in Los Angeles County, which claimed 30 lives and scorched 40,000 acres, underscored the deadly toll of these disasters.
Climate change is a major driver, creating hotter, drier conditions that fuel longer and more intense fire seasons. As wildfires become more common, understanding and mitigating the health risks of smoke exposure is more urgent than ever.
Wildfire smoke can trigger a range of symptoms, from burning eyes and runny noses to persistent coughs and breathing difficulties. For people with pre-existing conditions like asthma, COPD, or eczema, exposure can lead to dangerous flare-ups.
But the risks extend beyond the lungs. Fine particulate matter (PM2.5) can enter the bloodstream, causing inflammation throughout the body. Studies have linked wildfire smoke to increased emergency room visits for heart attacks and coronary heart disease within 24 hours of exposure. There is also emerging evidence that PM2.5 can impair cognitive functions such as memory and attention, likely by inducing inflammation in the brain.
Experts emphasize the need for proactive measures as wildfire season peaks:
If evacuation orders are issued, follow them promptly—not just for safety from flames, but from the health threats the smoke carries.
As wildfires continue to reshape landscapes and communities, their invisible legacy—on our immune systems and overall health—demands urgent attention. The message from scientists is clear: wildfire smoke is not just an environmental nuisance, but a profound health hazard that can affect anyone, anywhere the wind blows. Proactive measures, informed guidelines, and continued research are essential to protect public health in an increasingly fiery world.

Recent years have seen a rapid rise in kids vaping all over the world. A popular habit among young teens as well as young adults, vaping is the act of inhaling aerosol from electronic cigarettes or vape. But this popular habit has cost the health and well-being of this 24-year-old, who took to social media to warn people about this habit, as reported by the People.
A young man is taking to social media with a serious warning for anyone who uses e-cigarettes. He claims that vaping caused him to suffer a heart attack at just 24 years old and has led to lasting lung damage. Through a series of TikTok videos, Jacob Temple from Kentucky is urging people to quit vaping right away.
Temple, who started vaping at age 12, now says his lungs are like those of a 70-year-old man. He explained that he has permanent scarring on part of his lungs, meaning he can never fully inflate or deflate them again. "It feels like I’m breathing through a straw constantly, always, just never getting enough air and there’s nothing that can be done," he shared. This damage means he'll forever feel like he's not getting enough oxygen.
Temple also revealed that his vaping habit directly led to a "minor" heart attack, specifically an anterior myocardial infarction. He described the terrifying experience, saying, "My whole body was fighting to stay alive at a certain point." While the physical damage to his lungs can't be fixed, he hopes his story will motivate others to stop vaping before it's too late for them.
Temple admits he still has "good days and bad days." On some days, he can be active with the help of his rescue inhaler. However, on other days, he can barely function and struggles to sleep. He reflected on his past habit, saying, "It was fun while it lasted, but now I am paying for it dearly." His struggle highlights the long-term, painful consequences of what might seem like a harmless habit.
In a 2021 BMJ Case Reports study, researchers explored the link between vaping spontaneous pneumothorax, which is when air leaks into the space between your lung and chest wall, causing the lung to collapse. They also presented a case study of a A 34-year-old man, who was a healthy weight, came to the emergency room struggling to breathe and experiencing back pain for a full day.
An X-ray of his chest showed a large collapsed lung on his right side. He had quit regular cigarettes three years prior and switched entirely to vaping. A more detailed CT scan revealed bullae (air-filled sacs) in his lungs, and he had to undergo surgery to remove part of his lung. Lab tests on the removed tissue showed mild inflammation.
There are many other studies like the same, prompting researchers and healthcare professionals to issue warnings.
Temple’s case is not an isolated incident; there are many who have suffered the same fate.
According to Heart Organization, quitting smoking or vaping for good can seem tough, but it's totally possible. Just take it one step at a time. Here are five easy steps to help you on your journey to a healthier life.
Choose a day within the next week when you'll completely stop. This is your "Quit Day"! Promise yourself and tell supportive friends you're quitting. Slowly cut down before this day.
You have options: go "cold turkey" and stop all at once, or cut down slowly each day. For example, reduce cigarettes from 20 to 10, then 5. Or take fewer puffs from each one.
Speak with your doctor. They can tell you if medicines or other support tools, like patches or gum, would make quitting easier for you. Get their personalized advice to help you succeed.
Get ready for your Quit Day! Have healthy snacks ready, like fruits or gum. Plan fun activities to keep busy when you feel like smoking. Try a walk, movie, or new hobby to keep your hands busy.
