I think this would apply more for girls as my sister does this.
Her stomach fat makes her belly stick out post pregnancy, but the rest of her body is thin. Her jeans fit everywhere but her belly makes an odd fit. Very often she cannot button her jeans fully because of her big belly, sometimes she will put a belt over the button to hold her pants up but more often she cannot and being unbuttoned her pants keep sliding down. When unbuttoned the pants make a small bulge under her shirt. She constantly has to wear pants not buttoned fixing them.
Is this weird or do others do it? Any ideas how to fix this with her situation?
It's kinda weird... How long ago did she have the baby? I had the exact same problem as her right after my baby because my hips widened so much. It usually goes down though. She should wear yoga pants or other non-button pants for a little bit until her stomach is normal again. Or maybe skirts?
The way I view it is how permanent the situation is - Since it is post pregnancy weight there is a chance it may go and she will fit into jeans again but in the long term if you have to unbutton at waist all the time, the jeans don't fit and it is time to buy a new pair, go to the shop and try different brands/sizes till you get one that suits.
Some people just have a defined "gut" that sticks out and is not flat (in other words some people just don't have the body for an ultimate flat stomach). Could also be swollen, if she's allergic to something like diary (or has become allergic) then that could be factor, getting rid of that would tone it down. And also, diet. For me, drinking Coke for instance makes my stomach bloat really bad sometimes, even though I am a really skinny person. And also, filled stomach, you'll see a change in stomach size after she's gone to the toilet 😂😂 But anyhow, some people just seem to grow fat in their stomach rather than their butt, or boobs or legs. Just how their body works.
