It's normal to experience fatigue after bariatric surgery, especially in the first few months as your body adjusts to the changes. The amount of rest and sleep you need may change, and you may feel more tired than usual. However, it's important to listen to your body and not push yourself too hard.
It's possible that your energy levels may improve as you continue to heal and recover from surgery. It's also important to make sure you are getting enough protein and other essential nutrients, and to stay hydrated. Talk to your doctor or dietitian if you have concerns about your energy levels or nutrition.
