Obesity can increase the danger of surgery in general, and studies have shown that it increases the odds of bad consequences for hysterectomy patients in particular; the more fat a woman becomes, the higher the risk of hysterectomy problems. However many women with large amounts of fat still manage to recover after their operation without any additional difficulties. Being obese can also raise the risk of other diseases, such as diabetes and heart disease. Your doctor will take all these factors into account when discussing options with you. If you are worried about the effects of obesity on your ability to have a hysterectomy, then ask questions. It is important to understand what the risks are so that you can make an informed choice. Here are some tips for helping you lose weight before your surgery: 1. Make a plan - Set a date for yourself to have surgery, and set out a plan for changing your lifestyle afterwards. Decide exactly what you want to do to lose weight, for example using a food diary to note everything you eat for one week. Keep track of your activities, such as taking the stairs instead of the elevator or walking around the block every night after dinner. 2. Join a support group - Surgeons usually advise their patients to lose weight before surgery, but many women feel embarrassed to ask questions or express concerns.
