Are you always lactose intolerant or do you become lactose intolerant?

For the last year or so I have been suffering horribly with burning stomach pain, nausea, vomiting and frequent loo trips which has caused a 20 kg weight loss.

We have been trying to find the cause and I have had ultrasounds and blood tests and have seen a gastroenterologist who has suggested I get an endoscopy due to the length of time I've had the symptoms and my family history.

Recently I have had more of a flare up and have been quite ill so went back to my doctor and in passing I mentioned that I have suffered when much younger with chronic constipation exacerbated by drinking large quantities of milk and he suggested lactose intolerance. Amazing because I have seen many doctor's over the years with my other intestinal issues and not one of them has even suggested lactose intolerance. And I'm 33!

The doctor suggested eating a quantity of yogurt every day to see if it makes a difference and it really has.

But only in the last year have I had such extreme weight loss and being this ill. So did I always have an intolerance or did I just become lactose intolerant?

Has anyone got any other ideas that can help?

Update:

I should add that when I was 6 months old my mother stopped breast feeding and started me on cow's milk. She was shocked to find when changing my nappy one day that there was blood in my stool and I was swiched to Goat's milk without further incident. After a couple of years I tried cow's milk without a problem and was fine until I was about 10 when the constipation issues began but by then the lactose issues I had as an infant were I guess long forgotten.

    I became lactose intolerant in college after drinking a lot less milk than I had growing up with no problem, and my grandpa who is a doctor told me that for some people your tolerance for lactose can go down.

    I would definitely try eliminating it to see if it helps (severely lactose intolerant people can't even eat yogurt, butter or cheese), otherwise it might be IBD or Celiac or Crohn's which are more serious.

    Also if the yogurt is helping try a probiotic supplement too, more concentration of helpful bacteria!

    You can develop a lactose intolerance as an adult. I did when I was 34 and pregnant with my 3rd child. My other two kids were 2 and 4, so I was one busy mom! I drank a lot of milk; instant breakfast mixes with milk were often all I had for breakfast and lunch. I lost all my pregnancy weight plus 10 more pounds within 3 months after the birth. I lost so much weight, was hardly eating anything (I was afraid to eat anything other than rice and gatorade; seemed like everything else gave me massive diarrhea!), that I lost my milk and couldn't nurse the baby. I went through months of tests until finally the GI suggested I avoid all milk products. For the first time in 6 months I finally felt human again! Felt like I might live to see my kids grow up.

    Yogurt with acidophiles is easier to digest. Taking a supplement like LactAid can help you digest milk products. I still do not drink milk, and if I eat ice cream I take a LactAid. Cheeses and yogurts seem to be ok. So, Yes, you can develop a lactose intolerance as an adult.

    Very few people are born lactose intolerant. Being born lactose intolerant is disastrous, because infants are SUPPOSED to consume lactose as their entire diet.

    The majority of the population (more than 50%) become lactose intolerant at some point in their lives. Usually it happen gradually, starting as a teen, although it can start earlier or later.

    No, I won’t go with the answer that you become lactose intolerant

    you are born with it i guess...

    My dad and sister are lactose intolerant and they were born with it, but on the other hand if drinking milk and consuming diary products started making issues to you then I would consider that you change your diet...my aunt use to eat fish normally almost all her life only last year she began to have trouble eating fish and she didn’t eat it since then. You know every thing change with time, everything your body enzymes, immunity, just every thing…

    this goes for me too because reading what you’ve wrote here got me thinking of myself cause I almost share the same symptoms of yours and mine are very had too...

    By the way I did a CT scan to figure out what’s going on inside of me, and it was

    Colitis and IBS…

    Typically, lactose intolerance gets progressively worse.

    You can become lactose intolerant. I know of several people who developed it in later life. My sister-in-law actually was complaining of extreme bloating for no reason at all and its actually because of he love of cheese!
