i have posted this before on one hypo site but I can't remember where so i'll post it again because I think it's very important.
I was fine until around 20 years old then I started having to eat a huge meal every 2 or 3 hours then i'd be starving again and have to keep eating and I would still lose weight, celiac disease can affect different parts of your intestines in different people so you can gain weight too (sometimes in some people the whole small intestine can be damaged over time which often causes diarrhea ). Even right before sleep i'd eat a full meal and then i'd wake up with an extremely starved feeling after only 6 or 7 hours of sleep. I'd also be very cold, sick feeling, weak, pathetic, my joints would ache and be stiff, i'd get angry easily and get very warm sometimes, have lots of headaches etc, my body temp would be as low as 94.6 some mornings and average 96 and often my hands would be white and pale and cold feeling to others, not normal for me since cold never used to bother me much and i'm a man. I switched to "healthy" stone ground whole grain wheat bread and added more fat and meat, and much less junk food but that didn't help much. I had a 3 hour pee and blood sugar test and my sugar would go up pretty normaly then drop down very fast and quickly and stay too low (my numbers are lost in my room somewhere). Then my dad found out he had celiac disease at 50 and I looked into it. It took awhile for me to change my eating habits because cutting gluten and gliadins out of your diet is hard to do.... Lots of label reading (basically don't eat anything that lists a grain on it, anything that says modified food starch without saying corn etc, distilled vinegar, and gluten) but I finally did and it took a few weeks to start feeling better because your villi (the billions of little finger things in your intestines that absorb food) have to regrow. Now i'm around 14 percent body fat 150lbs (with damaged intestines I weighed 116 at lowest) and I can go without food for 8 hours and feel fine but a little hungry.
New studies show that more than 1 in 250 americans have celiac disease and an estimated 1 out of 20 type 1 diabetics and most don't know about it. Symptoms may or may not occur in the digestive system. For example, one person might have diarrhea and abdominal pain, while another person has irritability or depression. In fact, irritability is one of the most common symptoms in children.
The easier something is the more likely you'll do it.
One easy way to test yourself would be to make "blender soup" as I call it and eat it and a gluten free diet for a few weeks. The reason I like it so much is it's cheap, fast, easy, healthy, and gives me more time for fun instead of cooking and cleaning all the time. I use whole grain brown rice (quinoa might be best i'm going to try that next), split peas or some type of bean I like, then I add garlic gloves, onions, a lot of cold pressed extra virgin olive oil, salt etc. You can do the math if you want a precise mix of fat, carbs, protein. I use about a 30 cup pot and I just put it all in there and cook it, only adding the olive oil and anything else I think heat might harm at the last when i'm letting it cool then I mix it. When that's all done I put a little water and a fresh vegetable at the bottom of the blender then I scoop in the soup and blend on liquify with my oster 450 watt blender for 30 sec or so and then pour it into containers, some for freezing some for fridge (freezing changes the texture for some reason and makes you add more water but it's still ok, if anyone has a solution i'd like it.) I then have enough for 20 healthy meals or so I haven't actually counted but 30 cups is a lot of food. Then if you don't feel like making something and getting dishes dirty just get a big glass of blender soup and go have fun. Also using a blender to liquify vegetables like kale, celery, brussels sprouts etc is a great way to keep the beneficial fiber in the food unlike a juicer and remember even if it doesn't taste great you can drink it down in a few seconds then eat desert.
Here is a website that tells you about celiac disease, it's actually a genetic condition and your immune system overreacts to the gluten and then harms your own instestines but it has so many symptoms they call it a disease. Also someone I know was diagnosed with "irritable bowel syndrome" and later went to a more knowledgeable doctor and found out it was celiac disease. Always get a third opinion.
