What does the term 'dry weight' mean in hemodialysis treatment?

• A. The post-dialysis weight at which the patient has no excess fluid (euvolemia) and is used to guide ultrafiltration.
• B. The pre-dialysis weight with a history of fluid overload.
• C. The weight after dialysis when the patient is dehydrated.
• D. The weight corresponding to the dialysis session start.

Answer: (A)

Dry weight is the weight the patient reaches after a dialysis session when all excess fluid has been removed and the body is in a euvolemic (normal fluid) state. It serves as the baseline for how much fluid to remove in future sessions—the ultrafiltration target. Between treatments, patients tend to gain fluid (interdialytic weight gain), so the dialysis team uses this post-dialysis, no-fluid-overload weight to gauge and adjust how much fluid to pull next time. If dry weight is set too high, fluid overload and high blood pressure can persist; if set too low, removing too much fluid can cause low blood pressure, cramping, or dizziness. Therefore, dry weight is the post-dialysis weight at which the patient has no excess fluid and is used to guide ultrafiltration.
