If the big girl (or dude) is diabetic, insulin injection can create bruising at times if a blood vessel is clipped. Moreso if someone is taking an injectible anticoagulant such as Lovenox.
When I was bigger, I was a lot clumsier, and I had bruises I that I had no clue of the cause. My wife is still clumsy after losing 140 lbs…
We run into stuff more because we’re bigger and clumsier and everything is made for regular sized people.
We’re generally not tanned because we don’t go out in swimsuits as much as slim people, which means that bruises show up more lividly (if we are of the Caucasian persuasion).
If we are actively trying to lose weight and exercise more, we’re probably bruised from that. Right now I have several god-awfully ugly bruises on my legs from getting used to bicycling again.

I can appreciate there is a fine line between guessing and knowing, but in trying to speculate about the origin of mystery bruises how the heck is there going to be a hard objective answer to something that could have a number of causes? I posted my answer, and as an ex-fatty myself, and someone who was married to an overweight woman, I’m absolutely confident that it’s an accurate speculation, but how they heck is anyone (for this kind of somewhat amorphous question) going to have THE answer?

I think Karl is less concerned about the bruise question than other unproven assertions presented as fact.

Yeah, I assume it was the stuff about diabetes.
I guess it might have been nice if one of the docs had deigned to actually explain it, since the metabolic consequences of obesity are rather complex and it’s not something most of us understand very well.

Perhaps pressure bruises from armed chairs? I know (as an overweight man) that some armed chairs (office chairs, kitchen chairs, etc) can be a tight fit.

HA! Snorted beer out of my nose at that remark.

Another vote for varicose veins. My mother has them, and it honestly looks at times like someone has beat her legs badly.

Yeah, I would agree with you that it didn’t seem particularly egregious. But it didn’t seem possible to answer the other question without some guessery, so I assumed they were getting at the diabetes stuff. (Specifically, I assumed it was the bit about whether diabetes causes or is caused by obesity, or both.) I still don’t get why they decided to complain rather than offer up what they had in their great bulgey heads full of knowledge and assorted goopy stuff.
Well, the directionality of diabetes certainly is a contentious issue.

OK, OK, OK, I confess. The marks in question are not bruises at all, but hickeys. I did it. Away from my day job at the insurance company, I live by night as a fat-lady-leg-sucker. :o

This is in the top 1% of most disturbing images ever to cross my mind.
Besides the frequent minor injury due to bodily dimensions issue, more fat under the skin equals more deformation when you hit something hard. More deformation means a bigger area is affected. More fat also means that there’s a lot more tissue for blood to leak into when vessels rupture. Fat has less of a blood supply than skin and muscle. Less blood supply means that leaked blood doesn’t get cleaned up as fast by your body. What you end up with are more bruises, with a bigger overall area, that stay around longer, giving you something else to occupy your attention besides cellulite.

I really don’t want to sound like a pretentious prick, but, no matter how I phrase it, I’m sure I’ll come across that way. So, I’ll just cut right to the chase . . .
This is GQ, not IMHO. If you don’t really know the answer to a factual question that someone poses, please don’t guess.

Yep, you did. 
True, but if you’re going to “fight the good fight” here in GQ, why not fight against stupid joke answers? There are about a dozen of them here, all wasting time and hampster energy.
At least opinions such as LorieSmurf, NinetyWt, mojave66, lisacurl & Auntbeast are informed opinions, based upon their personal experiences. How can you get a better answer than that with such an OP?
I do know that taking asprin over a long period does lead to some spectacular looking bruises. Hefty dudes are more prone to back and similar pain, thus more prone to taking pain relievers, thus perhaps aspirin bruises.

*Medications and supplements can cause easy bruising
Blood-thinning drugs such as aspirin and warfarin (Coumadin) or medications such as clopidogrel (Plavix) reduce your blood’s ability to clot. Because of this, bleeding from capillary damage that would normally stop quickly may take longer to stop, allowing enough blood to leak out to cause a bruise*
The amount of bruising may also be affected by medications which interfere with blood clotting (and thus cause more bleeding into the skin or tissues). These drugs include many prescription arthritis medications called non-steroidal anti-inflammatories (e.g., ibuprofen/Advil, Nuprin and naproxen/Aleve) as well as over-the-counter medications, such as aspirin
