One of the most common complaints about adult incontinence care is “it still leaks from the side of the legs when put on”. Many people first suspect that the absorption is not enough, but the actual problem often lies in the wrong size, failed fitting, wearing method, body position change, or usage time. The following will teach you how to quickly determine the cause from simple to complex, and provide product and care solutions.
1. Ask three key questions first: size? Fit? Usage scenario?
Side leakage is mostly related to these three items. The wrong size causes gaps; the leg circumference is not tight or the vertical circumference collapses, and the liquid escapes along the gap; if it is not changed for a long time or lying on the side at night, the local instantaneous displacement exceeds the absorption area, which will also cause side leakage. Authoritative incontinence care guidance consistently emphasizes that the correct size and fit are more important than simple absorption value.
2. Ten common causes of side leakage (sorted by ease of improvement)
①Wrong size
When the waist circumference or hip circumference exceeds the range, the front and back of the diaper cannot be flat; too small core body is too small, and the thigh root has gaps. Measure the waist + hips and choose the larger value to select the size; patients lying down need to check the crotch depth again.
②Leakage-proof pleat collapse of leg circumference
Most adult diaper pants have an inner circumference; after putting them on, stretch them along the base of the legs with your hands to make the pleats stand up. If they are folded into the inner layer or flattened, the liquid will run directly to the side.
③The crotch is not unfolded
Folding, twisting, and piling of cloth in the crotch will block the diversion and form a “dam overflow”. Fold the core in half longitudinally before wearing it to activate it, and then unfold it to fit. Nursing training materials repeatedly emphasize this step.
④Insufficient absorption level or changing too late
Long-term wearing at night, severe incontinence, and continuous urination will saturate the core; the liquid will be diverted to the side. Choose night-time or high-absorption products and change them according to the frequency of urination. Experiments and standard tests (such as ISO 11948 Rothwell) show that laboratory absorption ≠ actual wearing capacity, and a safety margin must be left.
⑤Urgent “flood” exceeds the diversion speed
Patients with neurogenic bladder or urge incontinence have a large instant urination volume; if the diversion layer is slow, the urine column will hit the side first. Choose adult diaper pants with diversion grooves, fast surface layer or enhanced front area absorption.
⑥ Posture change: side-lying, half-sitting, wheelchair
Most core designs have the center of gravity on the central axis; when lying on the side, the liquid gathers on one side. Bedridden people should use widened hip side absorption, full-coverage pants or adjustable waist-fitting pants. Nursing home practice data suggests that posture and leakage points are highly correlated.
⑦ Inaccurate gender positioning
Men’s standing urination point moves forward; women’s sitting and lying distribution is more centered and posterior. Gender mismatch or failure to manually position will increase leakage from the front or leg side. The professional fitting guide recommends adjusting the humidity indicator line to the center after wearing.
⑧ Skin creams and oils cause poor sealing
A large amount of ointment at the base of the legs makes the elastic edge slide; slight movements will cause seams. Apply a thin layer and wear it after absorption.
⑨ Double-layered dressing error
Wearing two diapers together will squeeze the inner core, raise the leg circumference, and make it easier to leak. The correct way is to use a booster pad to increase total absorption, rather than double pants.
⑩ Feces and dirt block the diversion area
In mixed incontinence, solids block the diversion area; after turning over, urine bypasses the core and flows to the side. Clean it in time and use a waist-fitting or nursing home-level high-side circumference product that is easy to replace.
3. 3-step quick troubleshooting process (nursing version)
Step 1: Look at skin marks
Deep strangulation marks = may be small; no marks but with seams = may be large.
Step 2: Disassemble and inspect the moisture distribution of the core
Center saturated and side dry = insufficient capacity; center dry and side wet = poor fit; crease waterline = wrinkles.
Step 3: Record the scene
Side lying? Nighttime? Urgent urination? Long-term sitting in a wheelchair? Match the product after recording.

If you need adult nursing homes, retail brands, e-commerce exclusive or cross-age integrated supply (adults + infants), please contact us. Our team can assist with size planning, fitting training and market differentiation configuration.
6. Nursing skills: simple actions greatly reduce the leakage rate
Fold the product longitudinally before wearing to activate the vertical waist.
Align the center line; first, stick the lower crotch and then the upper crotch, and adjust the leg circumference pressure line.
Side-sleeping people should add absorbent pads, and should not wear two adult pants on top of each other.
Check the humidity indicator regularly; remind to change at night if necessary.
Wait until the skin is dry before wearing after applying skin cream.

Conclusion
Leakage from the side of adult diapers is not “destined”, but a “controllable variable”. By measuring the right size, wearing the right way, choosing the right absorption level, and matching the structure according to body position, leakage, skin problems, and care costs can be significantly reduced. As an adult diaper supplier for the global market, Yibero combines technology, leak-proof structure, and customized services to help channels and care institutions minimize the trouble of side leakage.
