I'm 29 Yrs Old with 44k Size Breasts, Should I Try for Gastric Bypass or Reduction?

Thank you for the question.

I think you will be much better off reaching a long-term stable weight  prior to undergoing breast reduction surgery. Reaching this lower weight will  allow for a safer breast reduction procedure and minimize the chances that additional surgery will be necessary when you reach a long-term stable weight.

 Best wishes.

Given your height and weight I would suggest weight loss or bariatric surgery prior to a breast reduction. With increased weight your risks of complications during and after surgery is greatly increased. It will be safer and healthier for you to wait on the reduction.

Your BMI is over 40 which makes you obese. You need to diet first - get your bmi under then 30 and the be re-evaluated for a possible breast reduction.
