Semaglutide doesn't have a set "life expectancy" in terms of how long the drug lasts in your body (it's cleared over days), but rather, studies show it increases the life expectancy of patients with type 2 diabetes or cardiovascular risk by reducing complications, adding fractions of a year (e.g., 0.12 to 1.7 years) to projected lifespans depending on the comparison group and patient risk factors, primarily by lowering heart/kidney risks and improving glycemic/weight control. The drug's effects on reducing major adverse cardiovascular events (MACE) and kidney failure are key drivers for these long-term life expectancy gains.
Adding semaglutide to SoC was associated with a wide distribution in life-years free of CVD gained, with a mean increase of 1.7 (95% CI 0.5–2.9) life-years.
Unopened compounded semaglutide lasts in the fridge until the expiration date shown on the vial. But after it's opened, compounded semaglutide only lasts in the fridge for 28 days. If you haven't used up all the medication after 28 days, throw it away and start a new vial.
Beyond its impact on fat, semaglutide also affects collagen, elastin, and muscle mass, accelerating the aging process and contributing to premature facial aging characterized by wrinkles, sagging skin, and a gaunt appearance.
Most patient will use Semaglutide for 6 months to at least one year, depending on their goals. Ultimately, the duration of Semaglutide treatment varies depending on factors like your starting weight, weight loss goals, your response to the medication, and your lifestyle regarding diet and exercise.
There's no official time limit for how long you can take semaglutide. Semaglutide is meant for long-term use to manage chronic conditions like type 2 diabetes and obesity. Stopping semaglutide often leads to weight regain, so some people may take it indefinitely.
“The combination of support in making lifestyle changes and tapering seems to allow patients to avoid regaining weight after coming off semaglutide.” says Dr Gudbergsen. “A patient's appetite returns when they stop taking the drug and if they stop taking it suddenly, they may find it hard to resist their cravings.
Wegovy can be a helpful addition to a weight-loss treatment plan for some people. But it's important to be aware of some of the possible side effects of this medication. Some side effects can cause long-term complications. These include gallbladder and pancreas problems, stomach paralysis, and blocked intestines.
"Ozempic hands" is a slang term for the visible changes in hands due to rapid fat loss from GLP-1 drugs like Ozempic, making them look thinner, bonier, and more aged with prominent veins, tendons, and thinner skin, as subcutaneous fat diminishes and skin doesn't fully contract quickly. It's not a formal diagnosis but a common cosmetic effect of significant weight loss, similar to "Ozempic face".
Ozempic is generally safe for seniors, but its use should be carefully monitored, particularly if you have pre-existing health conditions. In clinical trials of semaglutide, people aged 65 or older were more likely to experience side effects like nausea and vomiting.
Unable to get their prescription, some people have had to stop taking the medication abruptly or fear they may have to. If you are taking it for weight loss, there's no evidence yet that stopping semaglutide abruptly causes harm.
Key takeaways:
It's injected under the skin (subcutaneously) of the stomach, thigh, or upper arm. It shouldn't make a difference which injection site you choose for injecting Ozempic. And you can stick with the same area of the body or rotate areas each time.
A balanced Semaglutide diet plan should include non-starchy vegetables, whole grains, lean proteins, nuts, legumes, and fruits while avoiding sugary, fatty, and processed foods for optimal health and weight management.
“The studies I've seen say that patients tend to plateau with semaglutide at 60 weeks. So it's over a year, which is pretty good,” said Dr. Ali. Indeed, many people find that a weight loss method of any kind may stop working after a while.
Researchers from Queen Mary University of London's School of Biological and Behavioural Sciences, using the simple fission yeast as a model, have shown that new TOR inhibitor rapalink-1 prolongs chronological lifespan.
FDA issued a warning in July 2023 after receiving several reports of adverse effects from people who used compounded semaglutide. In some cases, compounders used the salt forms of semaglutide, which have different active ingredients than the approved drug.
'Ozempic legs' is an informal term describing visible changes in leg appearance—such as reduced fat volume, increased muscle and vein visibility, and looser skin—that some people experience during treatment with semaglutide (Ozempic) or similar GLP-1 receptor agonists.
Mostly, losing weight is an internal process. You will first lose hard fat that surrounds your organs like liver, kidneys and then you will start to lose soft fat like waistline and thigh fat. The fat loss from around the organs makes you leaner and stronger.
Ozempic can also affect the reward centers in the brain that release dopamine, which gives people pleasure from eating certain kinds of foods. While on Ozempic, a person may find eating certain kinds of foods less gratifying, which can help reduce calorie intake during the day.
However, compounded semaglutide is NOT FDA-approved, meaning it does not go through the same standardized testing, quality control, and safety regulations as Ozempic.
Amy Schumer stopped taking Ozempic because it made her feel "bedridden," severely nauseous, and unable to play with her young son, attributing her extreme reaction to a genetic marker (GDF15) that causes intense nausea, similar to her difficult pregnancies. She found the side effects—vomiting, lack of energy—made the medication "not livable," despite experiencing significant weight loss.
Precautions
But about half of people with obesity on this class of medications, called glucagon-like peptide agonists or GLP-1s, stop taking it within a year. Studies suggest that most people discontinue their use due to the high cost and adverse gastrointestinal side-effects.
You may discuss the possibility of reducing your maintenance dose to one injection every two weeks; however, if you start to gain back the weight you've lost, you may need to resume a once-weekly injection of semaglutide for weight management.
A 2024 cohort study published in Nature looked at more than 300,000 patients and found that those taking semaglutide (the active ingredient in both Ozempic and Wegovy) had a slightly increased risk of depression and suicidal ideation compared to those not taking the medication.
