💬 Frequently Asked Questions
🧪 How does liraglutide help with weight loss?
It acts like the body’s GLP-1 hormone, helping you feel full sooner, reduce appetite, and slow digestion so meals keep you satisfied longer.
⏱ When will I start noticing changes?
Appetite may decrease within days. Weight loss usually becomes noticeable over weeks as the dose increases.
😣 Will I get nausea?
Nausea is common at first. Dose increases slowly to reduce this. Eating smaller meals and avoiding greasy foods often helps.

Yes. Liraglutide helps the body handle glucose more effectively and is also used in type 2 diabetes at lower doses.
📆 Is this long-term?
Some patients stay on liraglutide long-term if it continues to help and is well tolerated.
🍸 Can I drink alcohol?
Moderate alcohol is fine for many people, but can worsen stomach symptoms or pancreatitis risk. Ask your clinician if you have a history of GI issues.

No. Liraglutide is not recommended in pregnancy or while trying to conceive.
