Honestly, just don't eat after midnight, and you'll be fine. You got an early one (which is very good for blood tests), so no worries about fasting there. You can have a nice big breakfast afterward.

The only blood test that requires fasting is glucose fasting, you are taking random glucose so you should NOT be fasting. If you go in with a fasting glucose when your doctor requested random he/she may think you are on your way to being pre diabetic when you are fine. Be sure to let your doctor know whether or not you have eaten in the event you get called for odd results.

      Nighttime Soiling (5 year old)

      By sh00148 · Posted

      Just had my daughter diagnosed and am currently awaiting blood test results for my son. As well as many bowel issues, mostly loose stools with mucus and lots of gassy moments sometimes leading to leaning stool, he has recently soiled himself in his sleep twice. He has been toilet trained for a long time, but is not waking up with the poo. It’s not just a little, it’s a lot.    We have had to make an appointment re his blood test results next week so will find out if it is coeliac too but I’m just wondering whether anyone else has had this? Ive read online that it could mean he’s constipated, but he poos all the time and it’s often soft, never hard.

      Scientists have discovered a cause of inflammatory bowel disease. They said it's a 'holy grail' discovery that could transform other autoimmune treatments.

      I know this isn't an IBS Forum, but it looks like they may have cracked the code on treating it.  They think the new discovery may make it possible to treat other autoimmune diseases.  Even if they develop a treatment I think I would continue eating strict gluten-free, but it may allow me to eat out gluten-free without the fear of being glutened.  That would be especially helpful when traveling.   I hope you find this article as promising as I did.   https://www.msn.com/en-us/health/other/scientists-have-discovered-a-cause-of-inflammatory-bowel-disease-they-said-it-s-a-holy-grail-discovery-

      By trents · Posted

      You still may have NCGS. NCGS shares many of the same symptoms of celiac disease but does not damage the lining of the small bowel as does celiac disease. There is no test for it. A diagnosis for NCGS depends on first ruling out celiac disease. It is 10x more common than celiac disease. Some experts feel it can be a precursor to the development of celiac disease. Eliminating gluten from your life is the antidote for both. You would do well to consider trialing the gluten free diet to see if your symptoms improve.

      My physician messaged and said I had a negative panel. I was diagnosed with IBS as a teenager and have had GI issues ever since. I have chronic diarrhea, abdominal pain, chronic fatigue, nausea. I am adopted and didn’t know my medical history, so I took a dna test a few years ago. I had tested positive for one of the markers, so said I was at increased risk of developing. The panel was to rule out, so I guess it’s been ruled out.
