Weight Loss with a BPD/DS
Typically, we expect BPD/DS patients to lose 75-80% of their excess weight over a 2-year period, although the majority of this weight is lost in the first year. Weight loss results for each patient are however different and your results will depend on how well you adapt your lifestyle and eating habits.
An example of expected weight loss:
- A 5ft 6in person weighing 17st (240lbs / 109kgs) has an ideal weight of about 11st (154lbs / 70kgs)
- They are carrying excess weight therefore of 240lbs minus 154lbs = 86lbs.
- 70% of 86lbs is around 60lbs
- So this person could expect to lose (on average) up to 60lbs (27kgs) which is between 4 and 4½ stones in weight
Because BPD/DS surgery can result in a significantly reduced absorption of key nutrients, it is much more likely to be associated with long term nutritional deficiencies. The most common problems relate to vitamin D, B12, folate, iron and calcium which result in anaemia and bone diseases such as osteoporosis. To guard against nutritional deficiency, you will need to take high concentrations of vitamins and minerals each day for life. It is also important that you have regular blood checks to make sure that your vitamin and mineral stores adequate to your needs.
If you follow these instructions you will avoid the long-term complications which could otherwise occur. Scientific evidence suggests that the majority of patients who comply with the follow-up requirements, including nutritional recommendations, do very well. Moreover, compared with obese individuals who have not had surgery, BPD/DS patients have a much lower risk of premature death and disability.
Excess or loose skin following weight loss
Due to the considerable amount of weight that BPD/DS patients typically lose, it's possible that you will experience some excess, loose or saggy skin. This most commonly occurs in the abdominal apron, or trunk area. The amount of excess skin you'll be left with following a BPD/DS operation varies and will depend upon your age and weight before the procedure. Generally, the heavier and older you are, the more likely you are to have extra skin. Younger patients tend not to have as much loose skin due to greater natural skin elasticity.
