The frequency of adult diaper changes depends on a number of factors, including the amount of urine an individual urinates, the absorbency of the diaper, and the need to stay dry for an extended period of time.

Generally speaking, one adult diaper can take on 2-4 urine changes. Some of the highly absorbent adult diapers on the market, such as the Reliable Reinforced Adult Diaper, are able to absorb 5-7 times of urine, with an absorption capacity of 1550ml, which is suitable for nighttime use or for larger urine volumes.

For cases of incontinence, it is recommended that the frequency of change be determined by the amount of urine passed. If the urine volume is high, it may need to be changed after each urination; if the urine volume is low, it is sufficient to change it after every 2-3 urinations. It is important to ensure timely changes to avoid skin irritation from excretions, thus preventing skin problems such as eczema.

When choosing an adult diaper, it is also important to consider a product that is breathable and dries well to improve the wearer's comfort and help maintain skin health. If there are special circumstances or questions, it is best to consult a doctor or other healthcare professional for advice.
