I don't know anyone that has been diagnosed as lactose intolerant. To my knowledge, people are unable to digest the lactate in milk, and it typically causes GI upset. I don't have GI upset, but every time I have milk, ice cream, etc, I get extremely phlegm-y. For at least an hour. It's mostly annoying because I feel like I'm clearing my throat ever 30 seconds, and then feels like I'm gagging or choking on the phlegm. Any ideas as to whether this could be an allergy or intolerance?
