Breast reduction 3 weeks ago: I have no appetite and bloated on upper part of stomach.

Bloating can be a side effect of the anesthesia, swelling, and slow digestion.     A lack of movement due to inactivity can also contribute to this as well. Walk around a little each day to stimulate digestion and appetite. Drink 8 glasses of H2O each day. Our office recommends that our patients take 100 grams of protein per day in the healing phase for the first six weeks following surgery.  You and your plastic surgeon can discuss specific brands to facilitate healing since you have no appetite to eat well balanced meals. If these issues continue, schedule a follow-up with your PS.Kenneth Hughes, MD, Board Certified Plastic SurgeonLos Angeles, CA

Best to be seen by your Poor a family MD or even Urgent Care for examination and possible testing. These are symptoms that need to be investigated.
