After childbirth, when you look in the mirror,

many people say,

“I can’t tell whether I gained fat or whether my skin is sagging.”

Even after your weight has mostly returned, your stomach may not

flatten out, or it may feel like it has lost elasticity even when you

tighten your muscles.

At this point, the important thing is to accurately distinguish whether

there is simply leftover fat, or whether the skin or muscles have

become loose.

Because the approach changes depending on the cause, the way to

address it also changes.

  1. Main reasons why belly fat remains after childbirth

Changes in the abdomen after childbirth cannot be explained simply

by weight gain.

During pregnancy, the abdomen expands significantly, and the skin

and muscles both stretch at the same time.

In that process, elasticity may decrease, or the rectus abdominis

muscles may separate.

That is why some people find that their belly does not flatten even

when their weight decreases.

In particular, when you pinch the abdomen, there are cases where fat

feels firm,

but there are also cases where it folds weakly or sags like wrinkles.

These two are completely different issues.

  1. Fat vs. sagging: how to tell the difference

The simplest criterion is the “feeling when pinched.”

When there is a lot of fat, the abdomen feels thicker and relatively

firm when pinched.

On the other hand, when sagging is the main issue, it tends to fold

thinly and feel loose and droopy.

Also, if the abdomen spreads sideways when lying down, the fat

component is usually greater. If it hangs downward when standing,

the likelihood of skin sagging is higher.

If rectus diastasis is present, the center of the abdomen may also

appear as a bulging protrusion.

It is important to check these differences first.

  1. Care methods needed in each case

If fat is the main cause, the basic approach is to reduce body fat

through diet control, aerobic exercise, and strength training.

If needed, procedures to reduce localized fat may also be considered.

On the other hand, if skin sagging or reduced elasticity is the main

cause, simple weight loss has limited improvement.

In this case, lifting-type treatments that improve skin elasticity, or

methods to organize loose tissue depending on the condition, may be

considered together.

If rectus diastasis is also present, core muscle strengthening exercises

are important.

  1. Why the wrong choice changes the result

If sagging, not fat, is the problem but you try to reduce fat only, it

may actually make the area look looser.

Conversely, if there is a lot of fat and you only focus on elasticity

management, you may not feel the expected change.

So for the abdomen after childbirth, the key is not “you must lose

weight no matter what,” but first identifying what type of condition

it is right now.

Only by setting that standard accurately can you avoid wasting time

and money and approach it in a direction that suits you.
