My gut has been getting steadily worse over the past 3-4 years. First I developed gluten sensitivity, then lactose intolerance. Put bluntly, milk makes me burp. I didn't think anything of it for a while, I thought it was more of an inconvience than anything else. I was sure it was the lactose because it's only lactose containing dairy that's the problem. Cheese and cream are fine. I've been minimising the amount of milk for about a year anyway, I only have it in one cup of coffee per day, but finally decided to take the plunge and cut lactose out completely. To ease the transition, I bought lactose free milk... and lactose free milk makes me burp just as much as the regular sort.
What on earth is going on?
