Heart burn , upset stomach with gas after TT/Breast Lift normal ?

It is hard to tell if the internal issues that you are feeling are in fact a result of your plastic surgery. If you are still feeling this way, I would only recommend to see your surgeon in person ASAP and complete any evaluation possible to see if those issues are a result of your surgery. Best of luck to you.

You need nutrition and supplementation if you can't eat enough.Key
factors in the healing of any wound are nutrition and vitamin supplements.
There are specially formulated vitamins that are designed to optimize
your healing that we use from Vitamedica. In addition, we use Arnica and
Bromelian to reduce the swelling and bruising. Before and after surgery,
nutrition is a key component that is overlooked by almost every patient and
surgeon. After the operation, your calorie and protein requirements are
increased. We design a nutritional regimen for each patient which is
provided to them during the preoperative teaching. In order to meet the
calorie and protein requirements after surgery, the patients typically
supplement using protein shakes. Calorie and protein intake are recorded
on a log that we provide and review at the postoperative visits. The
combination of homeopathic medicines, vitamins supplementation, and adequate
calorie and protein intake are critical to the wound healing process.
Prior to surgery, we ask the patients to stop all of their own
supplements as some can cause problems with bleeding during and after surgery.

Congratulations on your surgery!  These symptoms are not uncommon after a tummy tuck.  They tend to settle down and go away as time passes.  You can take over the counter remedies to help with the discomfort.  Be aware too that narcotic pain medicine can also contribute to some constipation, which also can be treated with diet changes and over the counter medications.  You will get there- keep your chin up!
