Your First Month on Semaglutide: What to Expect
Starting a new medication is a big step. The first month on semaglutide is usually about easing in, understanding how your body responds, and building routines that support the treatment.
Weeks 1–2: Getting Started and Dose Titration
Most people begin semaglutide on a lower starting dose that is gradually increased over time. The exact schedule can vary by product and by prescriber, but the goal is the same: give your body time to adjust and reduce the chance of side effects.
- One injection per week: Pick a consistent day and time and stick with it.
- Track how you feel: Appetite, fullness, nausea, and energy can all shift in the first 1–2 weeks.
- Stay hydrated: Sipping fluids through the day can help with mild nausea or headaches.
If you miss a dose or feel unsure about timing, don't guess. Reach out to your care team or pharmacist for specific guidance.
Common Side Effects (and When to Reach Out)
Many people experience mild, temporary side effects as their body adjusts. These are often related to how semaglutide slows stomach emptying and changes appetite signals.
- Queasiness or mild nausea, especially after larger meals
- Feeling full faster than usual
- Occasional bloating, belching, or heartburn
- Changes in bowel habits, like constipation or softer stools
Call your provider or seek urgent care if you notice severe or sudden symptoms—such as intense stomach pain, repeated vomiting, signs of dehydration, chest pain, or trouble breathing. Those are not "wait and see" situations.
Weeks 3–4: Settling Into a Routine
By the third and fourth injection, many people start to notice a more predictable pattern: meals feel smaller, snacking drops off, and it's easier to pause when satisfied. Weight changes can vary a lot—slow, steady progress is normal.
- Nutrition: Focus on protein, fiber, and balanced meals rather than "barely eating."
- Movement: Light, regular activity (like walks) often feels more sustainable than intense workouts right away.
- Sleep + stress: These heavily influence hunger signals and progress, even while on medication.
This is also the phase where you and your provider may discuss whether it's time to adjust the dose based on how you're responding and feeling.
Building Habits That Support Long-Term Results
Semaglutide is meant to work alongside your routines—not replace them. The first month is a great time to build habits that make future months easier:
- Plan simple, repeatable meals so food choices feel easier on busy days.
- Schedule your weekly dose with a reminder on your phone or calendar.
- Track trends, not perfection: weight, energy, sleep, and mood over weeks—not day by day.
Stay honest with your care team about side effects, mood, and lifestyle changes—this helps them tailor the plan to you.
