Arthur T Knackerbracket has found the following story:
[...]Research on 5,834 U.S. adults by Brigham Young University exercise science professor Larry Tucker, Ph.D., found people who drink low-fat milk experience several years less biological aging than those who drink high-fat (2% and whole) milk.
[...]Tucker investigated the relationship between telomere length and both milk intake frequency (daily drinkers vs. weekly drinkers or less) and milk fat content consumed (whole vs. 2% vs. 1% vs. skim). Telomeres are the nucleotide endcaps of human chromosomes. They act like a biological clock and they're extremely correlated with age; each time a cell replicates, humans lose a tiny bit of the endcaps. Therefore, the older people get, the shorter their telomeres.
And, apparently, the more high-fat milk people drink, the shorter their telomeres are, according to the new BYU study, published in Oxidative Medicine and Cellular Longevity. The study revealed that for every 1% increase in milk fat consumed (drinking 2% vs. 1% milk), telomeres were 69 base pairs shorter in the adults studied, which translated into more than four years in additional biological aging. When Tucker analyzed the extremes of milk drinkers, adults who consumed whole milk had telomeres that were a striking 145 base pairs shorter than non-fat milk drinkers.

You were probably already lactose intolerant at the genetic level (your body stoped producing lactase enzyme when you were around five), but you didn't notice it because you had little or no lactose-fermenting bacteria in your gut. At some point in your life (probably due more to your move to Asia than to antibiotics), those latose-fermenting bacteria moved in to your gut, starting to cause the classic symptoms of lactose intolerance that you didn't experience before.
Come to think of it, maybe the antibiotics played a role as well, decimating a formerly well established gut flora, breaking the equilibrium and opening the door to a new population that were present in your new country of adoption.

That's more or less what I was observing. There was a period where I was consuming a ton of live culture yogurts with strains of bacteria that are known to be able to digest lactase and it seemed to help. including S. Thermophillus, IIRC. But, eating enough to make that work is somewhat of a challenge and I haven't yet figured out how to get it to be self-sustaining.
I remember from my days studying microbiology that it's usually not a problem of too many bacteria, it's a problem of having the wrong mixture of bacteria or having bacteria in the wrong places. If you're going to nuke the population with wide band antibiotics, then you really ought to have a plan for restoring the ones that are friendly or neutral. If you've got the right mixture of bacteria, the ones that secrete nasty chemicals have to compete with ones that are either beneficial or neutral and the net result is a limitation of the harmful byproduct.
