You are considering Ozempic and want to know what happens during and after treatment. Below is an honest overview of results, timelines and, most importantly, how to prevent the pounds from coming back.
How Ozempic works in your body
Ozempic contains semaglutide, a substance that mimics a natural satiety hormone. The effect is twofold: you feel full faster after eating and your appetite decreases. This makes it easier to eat smaller portions without constant feelings of hunger.
You administer the injection yourself once a week with a pre-filled pen. You prick under the skin in your abdomen, upper arm or thigh. The dose starts low and is gradually increased to limit side effects.
Timeline: from start to finish
Week 1-4: build-up phase
You start with a low dose. During this period, your body gets used to the medication. Some notice less hunger immediately, others feel a difference only after a few weeks. Weight loss is still limited, often 1-3 kg, mainly fluid.
Week 5-12: first measurable results
The dosage is increased gradually, always in consultation with your doctor. After 12 weeks, you must have lost at least 5% of your starting weight to continue. Do you weigh 85 kilos? Then aim to lose at least 4 kilos. If this does not work, the treatment does not have sufficient effect.
Month 4-12: maximum effect
This is the period when most weight loss occurs. At Weightconsult, we aim for 6-10% weight loss. Individual results vary greatly. Some lose more, others less.

Common side effects
Especially in the first weeks experienced users:
- Nausea occurs in about 20% of users, especially immediately after eating. You reduce this by taking smaller portions and eating slowly.
- Stomach complaints such as feeling full, belching or slow digestion are common. Your stomach empties slower than normal, making large meals feel uncomfortable.
- Headaches and fatigue may occur in the first few weeks. Keep drinking enough and have regular meals, even if your appetite is low.
- In case of persistent or severe symptoms, consult your treating physician about dose adjustment.
After quitting: the reality of relapse
The hard news first: most people regain weight after quitting. Research shows that without a modified lifestyle, many users regain much of the weight they lost within a year.
Why does this happen?
As soon as you stop, your natural appetite returns. The hormone that Ozempic mimics is no longer artificially replenished. Your appetite returns as before, or sometimes even slightly stronger, as your body compensates for the period of reduced food intake.
Strategies to prevent relapse
Gradual phase-out
Don't stop suddenly, but reduce the dosage step by step over several months. This gives your body time to get used to decreasing support.
Lifestyle change during treatment
Use the period on Ozempic to learn new eating habits. Smaller portions, eating more regularly, choosing more consciously. You should be able to maintain these habits without medication.
Building structural movement
Regular activity - at least 150 minutes a week - helps you maintain a new weight. Strength training is especially valuable because more muscle mass supports your metabolism.
Consider maintenance dosage
Some people choose to stay on a low dose. You discuss this with your doctor based on your situation and goals.
Who does this treatment suit?
Ozempic is designed for specific target groups. You may be eligible if you:
- Are between 18-70 years old
- Have a BMI of 30 or above, or 27+ with weight-related health problems
- Have made previous unsuccessful attempts to lose weight
- Willing to adjust your diet
Ozempic is not suitable in certain conditions such as severe thyroid problems, history of pancreatitis or pregnancy.
Comparison with Wegovy
Both drugs contain semaglutide, but differ in dosage and approval. Ozempic is officially for type 2 diabetes, Wegovy specifically for weight treatment with a higher maximum dosage (2.4 mg vs 2 mg).
For weight loss, Wegovy is usually prescribed, but Ozempic is also used ‘off-label’. Which drug is the best fit depends on your situation, BMI and any diabetes. View the Wegovy injection page for a detailed comparison.
