A colostomy bag should ideally be changed when it is 1/3 full. This guidance is based on the need to maintain hygiene and comfort for the individual while preventing any potential leaks or skin irritation. A bag that is too full can lead to increased pressure, which may cause the adhesive to loosen or the bag to detach from the skin, resulting in a mess and possibly leading to infection.

Changing the bag when it is 1/3 full allows for a safe margin to manage contents without compromising the seal or adding excessive weight to the bag. Additionally, keeping the colostomy bag less than half full helps minimize the risk of odor and makes the changing process easier and more straightforward for the person managing their care.

The other thresholds, such as changing it when it is 1/4 or 1/2 full, may not provide the optimal balance between convenience and risk management. Waiting until it is completely full is undesirable as it can lead to significant complications, including discomfort and leakage. Hence, the timing at 1/3 full strikes a good compromise for regular maintenance.
