unfortunately it's impossible to give you an answer in a forum like this because we don't know your complete medical history and because your question can only be answered with a physical examination and possibly some routine blood work to get started. many things can cause fatigue. your tiredness may not even be related to the gastric bypass. only a medical professional can help you get to the bottom of what's causing your fatigue. you can start by making an appointment with your primary health care provider. he or she will perform routine tests and then refer you to a specialist if necessary. wishing you well!
