What dose should produce weight loss?
1 mg or higher for most patients on Ozempic; Wegovy at 2.4 mg is the FDA-approved weight loss formulation.

How long should it take?
Most patients see measurable loss by week 8-12 at therapeutic doses.

Can you build tolerance?
True tolerance is uncommon; plateau is biological adaptation.

Should I go to a higher dose?
Discuss with your prescriber; dose escalation is often the next step.

Does eating affect results?
Yes substantively; reduced appetite isn't the same as reduced intake.

Does alcohol affect weight loss?
Yes; alcohol calories don't engage satiety mechanisms.

Can sleep affect weight loss?
Yes; sleep deprivation alters ghrelin, leptin, cortisol, and insulin sensitivity.

What if I'm losing inches but not pounds?
Body composition change; muscle gain and fat loss can mask scale change.

When should I see my doctor?
After 12-16 weeks at therapeutic dose without progress, or sooner with side effects or symptoms.
