My father has been diagnosed with Celiac Disease. He also has irregular cells in his stomach that might be lymphoma, a common side-effect of Celiac Disease that has gone untreated for years. He must remove gluten from his diet, which effectively means my sister, who lives with him and cooks for him, must remove gluten from her diet, as well. They'll check the irregular cells in two months (after he's been gluten-free for a while) to see if they're lymphoma or not.
This disease is genetic. There is an inaccurate blood test, and symptoms can be so mild as to go unnoticed. If you remember how to do a Punnett square, parent 1 is nn (Celiac Disease is recessive), parent 2 could be anything (nn, NN, Nn), and my chance of having this is all over the map. I'm calling the doctor tomorrow to schedule the blood test, and I may be altering my diet just in case... I probably won't go comepletely gluten-free, but I'll limit my intake.
Just when I think life is calming down a little, I get slapped with something like this. I need a hug.
