I don't technically have Celiac Disease, but I'm on a strict gluten free diet that has completely cleared up digestive issues that I used to have. I was diagnosed with "colitis" over 20 years ago and then later told that I had IBS. I'm very familiar with Celiac.
Symptoms are diarhea, constipation or alternating, bloating, excessive gas, weight loss or weight gain, "brain fog", depression, and a host of other symptoms. For more information, go to www.celiac.com and you'll find a ton of help.
The ONLY treatment for Celiac Disease is a strict gluten free diet. At first it's hard, but it gets easier.
Diagnosed with Psoriatic Arthritis, 1996. Went away after eliminating wheat, eggs, soy and dairy from my diet.
Diagnosed with Minimal Change Disease, 2003. In remission since 2004 after fanatically eliminating all gluten from my diet.
