Poor your sister.
That's a heavy burden for a young person.
But..but, you are in the Netherlands.
She can go to a real Medical Doctor.
Did I look that up correctly?
I found, 'Irritable bowel syndrome'.
Having medical professionals make suggestions and keep records is so helpful.
I think people need to be Nannyed, a little. Someone professional to talk to.
I know from experience, keeping track and making choices about my own medical all by myself is difficult.
When I am very ill and /or in pain, going it alone is darned near impossible. And; I know that stuff.
When I looked IBS up, the first page from Mayo Clinic noted gluten.
She is not the only person that's trying gluten free.http://www.mayoclinic.org/diseases-cond ... n-20024578
Eliminating gluten. Research shows that some people with IBS report improvement in diarrhea symptoms if they stop eating gluten (wheat, barley and rye). This recommendation remains controversial, and the evidence is not clear.
Poor your sister.
I think she should see a qualified M.D. that will help her to find the diet, exercise and medicines that she can incorporate into her life for always.
From what I read, she can't go on 'fad' diets and spontaneous fasts. That could hurt her. All people need support sometimes. Her time is now.
I read Mayo Clinic's home remedy page.
Here it is. They have an alternative med page, too.http://www.mayoclinic.org/diseases-cond ... n-20024578
At the very least she will need records of what she eats and how that effects her.
When we write it down and look at it later, we see patterns and connections.
I'm doing that now, because of my little trip to the hospital.
Everything that goes in my mouth also goes in the book.
Those records are for me.
It's turned into a diary of sorts.
It was by looking in my book that I became aware, I am not getting enough calories.
I lose interest in food. I forget to eat. Who wants to eat when sick and tired?
I would have thought I was eating fine, if I didn't have a record.
(ech) Maybe school brainwashed me. But, writing it down Helps!
If you have a mild case, you might be able to keep it mild.
Let's cross our collective fingers.
Life is, just, an exchange of electrons; It is up to us to give it meaning.
We are all in The Gutter.
Some of us see The Gutter.
Some of us see The Stars.

Those that want to Know; Know.
Those that do not Know; Don't tell them.
They do terrible things to people that Tell Them.
