I've been paleo for a year, but starting last week I get heartburn after pretty much every meal! It's really very painful. I never had it before in my life and actually didn't even know what it was when I first felt it and nearly panicked. Now I sympathize!

Potentially helpful facts: I have been Paleo for well over a year, crossfitting for about 3 months and have never had a problem until last week. I haven't added any new foods recently. I started supplementing with Mark Sisson's Fish Oil/Vitamin D/Gut Flora combo about 3 months ago. I was very sick recently (worst cold I've had since going Paleo) and coughing to the point of losing my voice and abdominal soreness.

-Could the Gut Flora be doing this? Perhaps bacteria built up over time in my lower intestine and that's why I didn't feel it until now? is that even possible?

-Could I have damaged my stomach opening somehow with the coughing?

-Could it be caused by cold meds? The heartburn came on a week after I stopped taking them.

I read some great posts on here about how to treat heartburn, so I'm going to try the apple cider vinegar thing, but I really want to know what's causing it. Paleo isn't supposed to give me health problems I didn't have before! Boo!

What could it be?

UPDATE: Thanks for all your thoughtful responses. I cut out all the supplements and, after a week or so, started feeling relief. I added vitamin D back in without a problem. Two days ago I tried adding the fish oil back in at bed time and about 30 mins later, the heartburn was back! I haven't tried with the probiotics, I have just given up on those. Anyway, I think I found my culprit. It's really terrible, because I don't like anything other than salmon and I get bored of that pretty fast. What to do for those lovely omega-3s...I'm sure PH has a solution for that. Off to search i go, thanks again!

UPDATE 2 (1-31-13): I have stopped all supplements and 9 months later the "heartburn" is worse than ever. Went to a GI and an allergist and no one seems to be able to figure out what it is. I get it at random times throughout the day without any correlation to what I'm eating. It does not cause me to cough, but I do sometimes feel mucus coming up into my throat. I'm not even sure at this point if it's heartburn at all. Anyway, just thought I'd update in case anyone was following this. Hope you find more relief than I have!
