I can’t afford to keep this extra weight Thank you!! Will do 

Hello @Rubii, Since gluten is addictive and effects the opoid rececptors, some people have a withdrawal that lasts 10 to 15 days.  When alcohol or substance use is halted, the brain is forced to readjust to its sudden absence. This leads to unpleasant physical and mental withdrawal symptoms. Diarrhea, stomach pain, and vomiting are often experienced by people going through withdrawal from opioids and other drugs. Vitamin and mineral dificiencies are common and each has a set of symptoms. Vitamin D deficiency is ubiquitous in newly diagnosed celiac disease. Gluten containing processed food has some vitamins and minerals added to support the nutrients lost in milling.  There typically is no fortification to Gluten Free foods, so we need to be more aware. Low D compromises immune system, Thiamine and the other 7 B vitamins, Choline was B4 and is essential to fat digestion, deficiency can cause gallbladder symptoms.  

Sorry, in your first post you typed "a symptomatic" instead of "asymptomatic" so I misunderstood what you were saying. But anemia is a classic symptom of celiac disease.
