Yes, your “weight before treatment” is what you currently weigh. The amount of fluid you want to take off is the difference between your current weight and your target (dry) weight. If you don’t know your target weight, your doctor or home training nurse can tell you what they believe it is. How much you weigh from day-to-day can change as can your target weight. Your home training nurse can tell you ways to tell if you have gained too much fluid weight between dialysis treatments by monitoring your blood pressure, noticing if you have swelling in your hands, feet and ankles, whether you get short of breath, etc. Here’s an article by a patient about target weight that might be helpful.
