Why are fat people more prone to bruises?

Are they? My metabolism is fast I’ve always been a average weight without much flexibility on changing it. And holy shit do I bruise easy. I always felt like it depends on skin and sensitivity maybe blood situation. Cause ik being anemic can cause easy bruising. My skin is sensitive and I’m pail af so I get a bruise and you can see that shit a mile away. You’d be like “omg is that a walking piece of paper with a giant blue/brown smudge” just know it’s just me.

I don't know that they are. Some people just bruise easily.

Part of fat is made up of water.

Rearrange your bedroom so you don't keep bumping into the corner of your bed: nothing to do with your size I wouldn't think.

I'm fat and I do bruise easily, but that's because I take daily aspirin following a heart attack. Quite often I find bruises and have no idea how I got them, but hey, I haven't had another heart attack so I'm staying on the aspirin!

I'm white as hell. I bruise if you look at me crooked.

More surface area,

Im not sure

They aren't actually 'more prone' per se`, it is just that they show up easier due to fat tissues lower density than other tissue which allows more blood to swell in the area of impact.
