I am a 27year old female, and in may this year i had gastric sleeve done and i have lost 38kgs since then, but my major problems is that i cannot lose my excess skin (arm, hips, stomach, inner thighs) as i have also had 2x caesarean sections and this has been a complicated recovery, and now also my breasts are saggy

Please advice me how would be my best solution on getting rid of these problem areas, and also do i need to have breast reduction done as i have low self-confidence
