First, it's important to know that what you're experiencing is very common after pregnancy, even if you've returned to your pre-pregnancy weight. Pregnancy stretches not only the skin but also the connective tissue and abdominal muscles, and those changes don't always fully reverse on their own. Based on your description, it sounds like you may have a combination of mild skin laxity and changes in the underlying abdominal wall, rather than excess fat alone. The fact that you can easily pull the skin suggests there is some loose skin, while the persistent bulging raises the possibility of diastasis recti (separation of the abdominal muscles), which can make the abdomen protrude even in lean individuals. A physical examination is needed to determine whether muscle separation is contributing. At 17 months postpartum, your body has likely completed most of its natural healing. While maintaining a healthy weight, strength training, and core rehabilitation can improve muscle function, they generally have only a limited effect on excess skin. Whether to pursue treatment now or wait depends on the type of treatment you're considering: Non-surgical skin-tightening procedures may provide modest improvement in mild skin laxity, but another pregnancy could stretch the skin again and reduce the longevity of the results. Surgical procedures, such as an abdominoplasty (tummy tuck), are the most effective option for removing excess skin and repairing diastasis recti if it is present. Because a future pregnancy can undo many of these improvements, these procedures are typically best reserved until you have completed childbearing. The encouraging news is that you've already achieved your pre-pregnancy weight, which places you in an excellent position for any future treatment. If you're planning to have more children in the near future, it is generally more practical to postpone definitive surgical correction until after your last pregnancy. That way, you can address the loose skin and any muscle separation in a single procedure and maximize the longevity of the results. Your photos and history suggest that this is not simply a matter of body fat. Postpartum skin changes and the condition of the abdominal muscles both play an important role, and identifying which of these is contributing most is key to choosing the most effective treatment.
