Your first month on a GLP-1: what to expect
Dose steps, common side effects and the habits that help most in the first four weeks.
The first four weeks on a GLP-1 medicine are mostly about getting used to it. Doses start low on purpose, and most people won't see their full effect until later dose steps.
Start low, go slow
Every GLP-1 medicine is started at a low dose that is raised in steps: every 4 weeks for Zepbound and Wegovy, weekly for liraglutide, and monthly for the daily pills. If side effects are hard to manage, your clinician can hold you at a dose longer. That's normal and doesn't mean the treatment isn't working.
Common side effects and what helps
- Nausea: eat smaller meals, stop when you feel full, and go easy on fried or very rich food.
- Constipation: drink water through the day and add fiber gradually.
- Fatigue: eating too little can leave you drained. Keep protein at each meal.
Call your clinician or get care right away if you have
- Severe stomach pain that won't go away, with or without vomiting
- Signs of dehydration, such as dizziness or very little urine
- A lump or swelling in your neck, trouble swallowing or hoarseness
- New or worsening depression or thoughts of self-harm
Habits that make the biggest difference
Protein and strength training help protect muscle while you lose weight. Aim for regular movement you can keep up, like walking most days, and use your portal to tell your care team how you're doing before each dose step.
