How often should incontinence diapers be changed? The frequency of changing incontinence diapers varies from person to person and depends on the following factors:

1. Degree of incontinence:

Mild incontinence: If you only leak urine occasionally and the diaper absorbs less, you can change it every 4-6 hours, or change it in time when you feel the diaper is wet.

Moderate incontinence: If you leak urine frequently and the diaper absorbs moderately, it is recommended to change it every 3-4 hours, or change it in time when you feel the diaper is obviously swollen.

Severe incontinence: If you can't control urination at all and the diaper absorbs a lot, you need to change it every 2-3 hours, or change it in time when you feel the diaper is saturated.

2. Activity and water intake:

High activity and high water intake: It will increase the frequency of urination and urine volume, and you need to change diapers more frequently.

Low activity and low water intake: The frequency of urination and urine volume are relatively small, and the time interval between diaper changes can be appropriately extended.

3. Personal comfort: 

Even if the diaper is not fully saturated, it needs to be changed in time if it feels damp, uncomfortable or has skin irritation. When sleeping at night, you can choose a diaper with higher absorption to extend the replacement time and ensure the quality of sleep. 

Summary: There is no fixed standard for the replacement frequency of incontinence diapers, which needs to be flexibly adjusted according to personal circumstances. It is recommended that you: Observe your urination situation and diaper absorption to find the replacement frequency that suits you. Choose diapers with good absorption and good breathability to improve comfort. Pay attention to personal hygiene, change diapers in time, and avoid skin problems. If you have any questions about the use or replacement frequency of incontinence diapers, it is recommended to consult a doctor or professional caregiver.
