In the first few weeks following the procedure, the patient will notice distinctive changes in how they look and feel. Because most Liposuction techniques are performed as out-patient procedures, patients are generally able to go home the same day barring any significant complications. They should be ambulatory within the first few hours following the surgery and start walking as much as possible. This will speed up the healing process and reduce swelling on the treated area. The patient may feel groggy and sedated for a day or two even if no sedative has been used, and should not operate any heavy machinery or consume alcohol for at least 48 hours following the procedure. Although surgeons generally acknowledge that patients may return to work after two days, some need up to a week before they can return even to desk jobs. Fatigue and weakness are signs that the body is spending all of its energy on recuperating itself, and patients should not force themselves to do anything that might hinder their recovery or put unnecessary strain on their body. A normal exercise regime can be resumed after approximately two weeks.
