Have I become lactose intolerant? Watch
Posted from TSR Mobile
On whether you can BECOME lactose intolerant - I have no idea if it is caused by environmental factors or is hereditary or both. All I know is that if I want an easy morning I eat toast instead.
Go and see your GP to check what is really going on
I'm fine with any other dairy though.
Also the doctor is likely to ask you to cut out lactose then try it again after a few weeks to test anyway.
