If you are using 1500 ml of DEXTROSE-based solution:
1.5% has 16 grams of absorbable carbs x 4 calories per gram = 63 cals
2.5% has 26 grams of absorbable carbs x 4 calories per gram = 105 cals
4.25 % has 45 grams of absorbable carbs x 4 calories per gram = 180 cals.
You may need to limit the amount of calories in your diet while on peritoneal dialysis. Your body will get calories from carbohydrates or sugars in the food you eat and also from the dialysis solution that you put in your peritoneum. Carbohydrates in your diet include sugars from sweet foods and starches (bread, cereal, rice, etc). The dialysis solution also contains dextrose, which is a type of sugar. Your body will absorb calories from the sugar (dextrose) in the dialysate. The higher the concentration of dextrose, the more calories you will absorb. You will probably absorb at least 400 calories
a day from the dialysate. This may be helpful if you need to gain body weight.
If you do not want to gain weight, limit these foods:
desserts, cake, pie, cookies
butter, margarine, mayo
meat with fat on it
cream or whole milk
The range of calories absorbed for each bag and concentration of dextrose depends upon each patient's transport. The extra calories you absorb from each 2L bag of solution will be different for every patient, but close to:
a 1.5% bag has 90-100 calories
a 2.5% bag has 100-168 calories
a 4.25% bag has 200 to 284 calories
Keeping active and exercising on a regular basis can help burn off extra calories. Be sure to check with your health care team to see what kind of activities would be best for you.
