Lactose intolerance can be tested for with a stool sample
Casein allergy may come up in specific blood test. My understanding is that anyone over age of 2 with dairy problems is more likely to be casein than lactose because the vast majority outgrow lactose intolerance (although some may never eat lots of dairy in comfort)
Great question as i was wondering this myself. Sorry I can't help you-I just started a cf diet with my son because both husband and I are lactose intolerant.
I was wondering if you guys know if there is a difference between being casein intolerant and lactose intolerant and how do you check for it?
I ask because I'm doing a dairy challenge on my non-ASD 11y dd. She was off dairy for 3 days and today was the trial. She ate milk, yogurt, cheese, ice cream. I really loaded her up. She has felt sick all day long. Stomach ache on/off and feeling just plain old tired, no energy, etc.
How do I know if it's from the milk protein or lactose? I plan on doing the 3 day elimination again and then try the Lactaid pills---to see if it works.
I hope she is only lactose intolerant, instead of casein too!
What do you guys think?
If it's the lactose allergie the enzymes should work or get Lactade milk. Daniel never drank diary until age 2 he threw up with it before. Diary is ok for him now. He has no gi issues also strange!My son is lactose intolerant. He was diagnosed by an allergy doctor on the basis of symptoms. Ever since he was a baby, he has gotten softer, more frequent bowel movements when he:
- eats too much dairy
- eats dairy on an empty stomach, for example yogurt for breakfast. He tolerates yogurt at other meals, and lactose-free milk is fine at all meals.
- eats ice cream or drinks regular milk
He shows no signs of getting a stomach ache, but he used to get agitated when he was little. Now he understands when he needs to poop and doesn't postpone it or get confused by the sensations, so we don't see the agitation anymore when his system is overwhelmed by dairy.
It is my understanding that the hospital tested him for peptides in his urine which indicate gluten and casein intolerance. His urine test was normal. So it's possible to have lactose (milk sugar) intolerance without casein (milk protein) intolerance.
You can order the peptide test online, but it's possible a regular pediatrician can do it. There's probably a lab test for lactose intolerance, but like I said my son was diagnosed on the basis of symptoms.
Good luck figuring this out.
I believe lactose is milk sugar and casien is milk protien. Wheat and dairy protiens are identical, which is why parents are doing the gluten-free/ casien-free diet.
