The short answer

The first month often brings early appetite changes, some front-loaded side effects, and gradual, uneven progress, though your own experience may look different.

What generally happens in the first two weeks?

Many patients notice appetite changes fairly early, sometimes within the first week or two. This is also when side effects, especially mild GI symptoms, tend to be most noticeable. Your body is adjusting to a new medication, and this early period often settles as treatment continues.

Why does my first dose feel lower than I expected?

Your first dose is typically an introductory dose, not your target dose. Starting low gives your body time to adjust before any increase. This is a standard part of titration, not a sign that your treatment is behind schedule. Article 3 covers how dosing decisions get made in more detail.

Is it normal if my weight doesn't move in a straight line?

Yes. Weight change during this process is usually gradual and non-linear, meaning it can go up and down slightly week to week even as the overall trend moves in one direction over time. Many patients see changes in appetite and weight over time; individual response varies. A single week is not a reliable signal on its own.

Why do hydration and protein matter from day one?

As appetite drops, it becomes easier to under-eat protein and under-drink fluids without noticing. Prioritizing protein and hydration from the start helps support your body through the appetite changes this medication class can cause. Article 21 covers nutrition strategies in more depth.

What does the check-in schedule look like in month one?

Most patients have at least one scheduled check-in during the first month, in addition to open access to portal messaging. Your account shows your specific schedule. Check-ins in the first month often focus on tolerability and any early side effects.

When should I reach out before my scheduled check-in?

Reach out proactively if a symptom is bothering you, getting worse, or affecting your ability to eat, drink, or function normally. You do not need to wait for a scheduled check-in to message your clinician. Waiting is fine for mild, improving symptoms.

When this may not apply to you

• You have a chronic condition that requires closer monitoring (diabetes, heart disease, kidney disease) → message your clinician about what to expect for you.
• You are pregnant or breastfeeding → message your clinician.
• You had a significant reaction to a prior medication in this class → message your clinician before starting.

If something feels wrong

• Emergency — call 911 or go to the ER now. Signs of a severe allergic reaction (swelling of the face, lips, tongue, or throat; trouble breathing; widespread hives); severe, persistent abdominal pain radiating to your back, often with vomiting; chest pain; severe low blood sugar (confusion, loss of consciousness, seizure); signs of severe dehydration (unable to keep fluids down for more than 24 hours, minimal urination, extreme dizziness on standing).
• Contact your clinician within 24 hours. Persistent vomiting; inability to eat or drink for a full day; new or worsening abdominal pain that is not severe; an injection-site reaction that spreads or worsens after 48 hours; right-upper-abdominal pain, especially after fatty meals; heart-rate changes you can feel at rest; new or worsening depression, anxiety, or thoughts of self-harm; yellowing of skin or eyes; fever above 101°F.
• Usually okay to wait for your next check-in. Mild nausea that is improving; occasional heartburn; constipation or mild diarrhea responding to standard measures; fatigue in the first weeks of therapy; small injection-site redness resolving within 48 hours; small changes in taste or appetite.
