2. Wash Yourself
Feel free to bathe or shower before the surgery. If your healthcare provider has given you a specially medicated soap, be sure to follow the instructions to use it. If you didn't receivea medicated soap, use an antibacterial soap purchased from your local pharmacy. Remember to scrub your fingernails thoroughly, and remove any nail polish, jewelryand makeup.

4. Do Aerobic Exercises
Aerobic exercises such as jogging, bicycling or swimming canimprove your lung function. You can also practice deep breathing to improve lung capacity.After anesthesia, the tiny air sacs in your lungs called alveolimay collapse and cause a condition called Atelectasis. Aerobic exercises and deep breathing help expand the alveoli andprevent atelectasis.
5. Improve Your Nutritional Status
Improving your nutritional status helps your body heal faster after a surgery. Your surgeon can assess your nutritional status by testing the level of a protein called albumin in your blood. Low levels of albumin can result in worse outcomes for patients undergoing surgery. Attention to nutrition is even more important for patients with Diabetes, because high blood glucose levels are toxic to cells and can disrupt normal wound healing.
6. Avoid Smoking
The smoke from cigarettes causes poor wound healing because nicotine can makethe blood vessels constrict, decreasing blood supply to the cells of the wound. Besides, nicotinealso contains toxins that impede wound healing. If you can’t quit, at least avoid smoking during the healing process to help your wounds heal faster.

An appropriate fasting period prior to surgery using anesthesia is essential for a person’s safety. Prior to the scheduled surgery, people are usually recommended to eat or drink nothing for at least 6 hours, and preferably 8 to 12 hours. Some reasons for fasting include:
- For gastrointestinal surgery: If the surgery involves the gastrointestinal track, the stomach has to be as empty as possible before surgery to prevent leakage into the abdominal cavity. Sometimes bowel preparation will be done before the surgery. The surgery may be cancelled if you don’t follow the fasting rules.
- For other surgeries using anesthesia:After ananesthesia, food in your stomach may be inhaled into your lungs during the surgery,which can cause a lung infection and lead to aspiration Pneumonia.Eating shortly before elective surgery may also lead to postoperative nausea and vomiting. Vomiting after surgery can be very painful, because the incision and your throat can already be sore from the procedure itself.Fasting can help prevent these dangerous consequences from happening.
- Note: Do not be tempted into consuming a heavy meal before you begin fasting because it takes longer to digest. Choose a light meal such as soup and salad as a final meal before surgery.
