Acceptable interdialytic weight gains are how many percent of TW?

• A. 3-5%
• B. 1-2%
• C. 6-8%
• D. 9-12%

Answer: (A)

Interdialytic weight gain is the extra fluid a patient accumulates between dialysis sessions, expressed as a percentage of TW (the target/total weight used for dry weight). Keeping this gain around 3-5% of TW provides a practical balance: you remove enough fluid during the next session to prevent fluid overload, but not so much that the patient becomes unstable during dialysis. If interdialytic weight gain is much higher (6-8% or more), it indicates significant fluid overload and requires more aggressive ultrafiltration, which raises the risk of intradialytic hypotension, cramps, and cardiovascular strain. If it’s only around 1-2%, it suggests fluid restriction may be tighter than necessary and could contribute to dehydration risks. Therefore, 3-5% of TW is the appropriate range.
