For two years I have suffered syntoms of celiquism or colon irritable. But blood test were all good. What can I do to releve stomach eaches gases etc?

?IBS. Irritable Bowel Syndrome (IBS) is truly a diagnosis of exclusion, and there are no specific blood tests for it, but this may certainly be your problem. See the following MAYO Clinic link for information and help.
Food allergy? Some find being tested for food allergies and avoiding their culprits really helps. Gluten-free is in fashion right now and, indeed, if you're allergic - it makes a big difference. Other foods are common problems to some people. Avoiding as much stress as possible can help (CBT therapy) as can learning your best eating patterns. Some do best w/ small multi-meals. Drink water before, NOT w/ meals.
