Frequently Asked Questions

When can I drive?

When can I return to work?
Many patients return to desk work within 2–4 weeks, depending on their recovery and job requirements.
Is it normal to feel tired?
Yes. Fatigue is common during the first several weeks as your body heals and adjusts to a lower calorie intake.
How much weight will I lose during the first month?
Weight loss varies from person to person. Some patients lose weight rapidly during the first month, while others lose more gradually. Focus on following your nutrition and activity plan rather than comparing your progress to others.
When can I exercise?
Walking should begin immediately after surgery. More strenuous activities should be resumed only after clearance from your surgeon.
