How Semaglutide Works
Semaglutide is a GLP-1 receptor agonist, a class of medications that mimics the glucagon-like peptide-1 hormone your body naturally produces. This hormone plays a role in regulating blood sugar levels, slowing gastric emptying, and signaling fullness to the brain.
Originally developed for managing type 2 diabetes (as seen in Ozempic®), semaglutide is also FDA-approved under the brand name Wegovy® for chronic weight management in adults with obesity or overweight and at least one weight-related condition.
Whether prescribed as part of a type 2 diabetes treatment plan or as a metabolic health intervention, the way semaglutide functions in the body may influence how long providers recommend continuing treatment.
What Happens If You Stop Taking Semaglutide?
In clinical trials, patients who stopped taking semaglutide often experienced a gradual return of weight or elevated blood sugar levels, especially if lifestyle changes weren’t sustained.
One study published in Diabetes, Obesity and Metabolism found that participants who discontinued semaglutide after 68 weeks regained an average of two-thirds of the weight they had lost within one year of stopping treatment.
This does not mean semaglutide must be taken forever. Instead, it highlights the importance of having an ongoing plan for metabolic health, whether that includes medication, lifestyle changes, or both.

What Licensed Providers May Consider
Licensed healthcare providers typically consider several factors before deciding how long a patient should stay on semaglutide:
- The reason for prescribing semaglutide may depend on whether it is being used to support blood sugar control or for chronic weight management.
- A patient’s health history, including insulin resistance, prediabetes, hypertension, or cardiovascular risk, may influence the recommended duration of treatment.
- Providers may evaluate a patient’s goals and progress, adjusting or discontinuing treatment based on how well the medication is working.
- Tolerability and side effects, including any changes in laboratory values, may prompt a provider to adjust the dose or reconsider the treatment plan.
In many cases, semaglutide may be used as a long-term treatment, particularly when addressing chronic conditions like obesity or type 2 diabetes. However, how long a patient stays on the medication should always be guided by the individualized judgment of a licensed healthcare provider.
Is It Safe to Take Semaglutide Long-Term?
Long-term studies of semaglutide, including SUSTAIN* and STEP trial extensions**, have shown that it may be safe and effective when taken over an extended period, with ongoing monitoring by a licensed healthcare provider.
For example, in the STEP 5 trial, semaglutide 2.4 mg (Wegovy®) was evaluated over two years and continued to show benefits in weight reduction and maintenance when combined with behavioral therapy.
However, it’s important to note that:
- Side effects such as nausea, vomiting, or fatigue may occur
- Regular check-ins and lab work may be recommended
- Treatment plans may evolve as your needs change
As with any medication, ongoing use should be re-evaluated regularly by a licensed provider to ensure it continues to align with your goals and health status.
*The form of semaglutide used in SUSTAIN trials was the once-weekly subcutaneous injection, marketed under the brand name Ozempic®.
**The semaglutide formulation used in this trial is the same as what was later approved and marketed under the brand name Wegovy®.

What If You Reach Your Goal?
If you’ve reached your target weight, improved key health markers, or stabilized blood sugar levels, you may be wondering: Can I stop taking semaglutide?
Possibly, but not without medical input.
Some licensed healthcare providers may recommend tapering or stopping the medication gradually, while continuing lifestyle strategies that support your results. Others may recommend ongoing, lower-dose maintenance if discontinuation puts you at risk of health setbacks.
Either way, it’s important not to make changes to your treatment plan without professional guidance. Abruptly stopping semaglutide can result in rebound effects if the underlying causes of weight gain or insulin resistance haven’t been addressed.
Conclusion
So, do you need to take semaglutide forever? Not necessarily, but for many, it may be a longer-term part of managing a chronic condition like obesity or type 2 diabetes. Whether you're just starting or you’ve already been on semaglutide for some time, it’s essential to work with a licensed healthcare provider to understand what’s best for your body, your goals, and your health trajectory.
Licensed providers available through the Eden platform evaluate each patient individually and may help determine whether continued use of semaglutide or an alternative strategy is most appropriate.
