What is indicated by today's pre-treatment weight minus the target weight?

The difference between today's pre-treatment weight and the target weight reflects the patient's interdialytic weight gain. This measurement is crucial for dialysis patients as it helps assess fluid management between dialysis sessions. Interdialytic weight gain indicates how much fluid the patient has accumulated since their last treatment, which can provide insights into their dietary and fluid intake. Monitoring this gain is essential to avoid complications associated with fluid overload, such as hypertension and heart strain.

Understanding this concept helps healthcare providers tailor treatment plans effectively, ensuring that patients receive the appropriate amount of fluid removal during dialysis sessions to maintain optimal health and prevent excess fluid retention.
