How Long Does Casein Reaction Last?

[GFreeMO]

I decided to test my casein reaction 2 days ago. I never was confirmed to have a casein allergy so I wasn't sure if it was that or lactose. I know now that I can't handle casein. It caused cold sores, a migraine, knee pain and mucus poop. How long does casein stay in your system? I drank about a cup and a half of whole milk.

My casein reaction symptoms are sinus congestion and drainage, bloating and excruciating cramping intestinal pain (more like menstrual cramps than my gluten reaction). When I first began to abstain from casein and accidentally consumed dairy, my reaction symptoms lasted 7-10 days. Years later, when I accidentally consumed casein, my reaction symptoms lasted at least 2 weeks. For most people their reaction symptoms are stronger and longer as abstinence time passes. I never 'tested' my diagnosis, because I'd suffered reaction symptoms from dairy for years. I suspected lactose intolerance, but lactaid treated products didn't completely eliminate my symptoms. So I suspected I reacted to the casein protein, not just milk sugar (lactose).

I have the exact same symptoms with similar cramping and a sinus headache. Thanks for the info. I need to be more careful. I need to get out my blender and make some rice milk today.

Hopefully the symptoms wont last too long.

Was that your complete test? If so, from my understanding, milk contains both lactose and casein, so a more accurate test is to consume something with only casein and no lactose, such as hard cheeses like swiss and cheddar. If a cheese nutrition label says "zero" sugars, that means there are no lactose sugars.

I wondered the same thing, and still do. Dairy gives me GI trouble as well as pimples. I can handle hard cheese in small doses and not get GI trouble, however I will still get a few pimples. I truly don't know what that means for me, but I'm leaning toward sensitivity toward both lactose and casein.

Well wishes,
