HimI m dr.hema physiotherapist . I understand your concern. There are various types of surgeries and side effects depends on it. Doctors usually perform laser lipo underlocal anesthesia(IF NOT LASER then has to undergo general anesthesia) With laser liposuction, the surgeon uses a thin tube, less than one millimeter in diameter, to melt and liquefy the fat in place. This liquefied fat then leaves your body in one of three ways. Unfortunately, while relatively uncommon, complications do occur. An adverse reaction to the anesthesia. Fluid loss, blood clotting,pulmonary embolism, or infection. Less serious difficulties include Numbing or excessive pigmentation of the skin, bruising,allergyand scarring. Risk of complications is usually associated with how large the procedure is, as well as the surgeons skills . But the non-invasive way to go, with laser liposuction, may recover faster and with or without fewer complications than with other procedures. Any procedures do has complications and careful post op guidance helps to manage. Before considering surgery I want you to consult a dietician and get a proper diet.Along with a proper diet,a proper set of exercises should be advised by a physical trainer with supervision. Even after you fail you can consider sugery. Hope this helps you to take decision.
