Long-Term Effects of Wegovy®: Understanding the Benefits and Risks

Wegovy® (semaglutide) is best known for its short-term effects — appetite control and weight loss. But for many patients, the bigger question is what happens long term.

If you’re considering Wegovy® for ongoing weight management, or you’ve already started treatment, it’s important to understand both the benefits and potential risks of using this medication over time.

The reassuring news: Wegovy® is considered safe for long-term use for most people when prescribed appropriately and monitored by a healthcare provider. Like any medication, it comes with potential side effects, but serious long-term risks are uncommon.

What Are the Long-Term Effects of Wegovy®?

The most consistently observed long-term effect of Wegovy® is sustained weight loss.

Clinical studies following patients for up to two years show that:

· More than one-third of patients maintained 20% or greater weight loss

· Many others sustained 10–15% weight loss long term

· Weight loss was more likely to be maintained when treatment continued

These results are clinically significant and are associated with improvements in:

· Blood pressure

· Blood sugar control

· Cholesterol levels

· Mobility and quality of life

Is Wegovy® Safe for Long-Term Use?

Yes. Wegovy® is generally considered safe for long-term use in appropriate patients.

Semaglutide — the active ingredient in Wegovy® — has been used for many years to treat type 2 diabetes under the brand name Ozempic®. Because diabetes is a chronic condition, many patients have taken semaglutide safely for extended periods.

While all medications carry some degree of risk, studies show that for people with overweight or obesity, the health benefits of sustained weight loss typically outweigh the potential risks.

Common Side Effects of Wegovy®

The most common side effects are gastrointestinal and usually occur:

· When starting the medication

· When the dose is increased

Common side effects include:

· Nausea

· Diarrhea

· Constipation

· Heartburn

These symptoms are typically mild to moderate and tend to improve as the body adjusts. Many patients find that side effects resolve on their own within a few weeks.

If side effects persist or interfere with daily life, a healthcare provider can help adjust dosing or provide supportive strategies.

Rare but Serious Side Effects

Although uncommon, some serious side effects have been reported and should be discussed before starting treatment.

These include:

· Pancreatitis

· Gallbladder disease (including gallstones)

· Kidney problems, especially if dehydration occurs

· Increased heart rate

· Worsening diabetic eye disease in people with diabetes

· Mental health changes

· Thyroid tumors (observed in animal studies, not confirmed in humans)

Because of these risks, Wegovy® is not appropriate for everyone.

Who Should Not Use Wegovy®?

Wegovy® should not be used if:

· You are allergic to semaglutide or any of its ingredients

· You or a family member has a history of medullary thyroid carcinoma (MTC)

· You have multiple endocrine neoplasia syndrome type 2 (MEN 2)

· You are pregnant or planning to become pregnant

A thorough medical evaluation is essential before starting Wegovy®.

Do Wegovy® Side Effects Go Away Over Time?

For most patients, yes.

Side effects often lessen as the body adapts to the medication. Some people experience symptoms only at the beginning, while others may notice side effects during dose increases.

If Wegovy® is discontinued, side effects typically resolve.

How Long Can You Take Wegovy®?

Wegovy® is designed for long-term weight management, not short-term use.

There is no fixed maximum duration for treatment. Some patients take Wegovy® until they reach their goal weight, while others continue beyond that point to help maintain results.

Your healthcare provider will help determine:

· How long treatment is appropriate

· Whether ongoing use is beneficial

· When adjustments should be made
