The stitches are removed in a week. However, during the first two weeks it is necessary to carefully monitor your health condition, because there is a risk of infection, inflammation and bleeding. Swelling, as a rule, goes off on the second or third week, and then you need to move on to light physical activities. Especially it is recommended to walk, which prevents the formation of new swelling.
It is necessary to keep to a healthy diet, to reduce salt and fluid intake (to avoid swelling). You can't smoke (this significantly affects blood circulation and wound healing), you can't lose or gain weight. Women return to the usual lifestyle and do sports not sooner than in 2 to 3 months. The breast begins to feel as "own" in a year after operation, then you can get pregnant and breast-feed.
Please note: after having mammoplasty, for the first month, 24 hours a day, you need to wear special correction underwear, which the doctor will recommend. Then you move on to the elastic sports bras, which pull the breast. To the regular underwear you can return not sooner than in three months. However, until the mammary glands take their permanent shape, it is better to avoid bras with bones and push-ups and to give preference to underwear made of natural cotton.
