@eerie: It's difficult to say... I've always seemingly had horrible issues with lactose intolerancy. I would cut back on milk/get lactose free alternatives but I had issues with bleeding and whatnot. Doctors always couldn't find anything, assumed it was IBS or something. Long story short, my mom did research and (with the suggestion from my doctor) we decided to have me go 2 months no gluten. It sucked at first, but I started to notice these changes for me:
I was less swollen and achy.
Less migraines.
Less lethargic (and I mean debilitating, flu-like level of lethargy.)
No more bleeding and cramping.
I had to eat an immense amount of lactose to irritate my gut.
Long story short, my doctor explained that people with lactose sensitivity can also end up with gluten sensitivity, and they can aggravate each other. She tested me pre-diet change for Celiac, but it was negative despite having symptoms. She didn't want to put me back on normal to do a biopsy though. So ever since I just avoided and I've felt a ton better, even if it limits my dining options. And plus, I find a lot of GF stuff is actually a lot higher quality. Pure chocolate in chocolates, good ingredients in most foods. Does it always taste great? nah. Is the texture the stuff of nightmares? Yes. xD
Anyways that's longer than you probably wanted to read but... Yeah. Sorry. xD
