<<Disclaimer: Verify this information before applying it to your situation.>> ListMembers, This was Dr. Murray's response to a personal message I had sent to him regarding a recent incident with low blood pressure: Debra Resch New Jersey ----------------------------------------------------------------- This is not medical advice. The blood pressure may drop following the gluten ingestion in a treated celiac for any one of several reasons. The most likely is third spacing of fluids. This a common happening in patients who develop a gastroenteritis or inflammation of the gut. Greatly increased amoints of fluid are lost into the gut lumen leading to loss of fluid from the blood and tissues. This leads to a drop in blood pressure and effective dehydration. Acute diarrhea may occur with the loss of fluids into the toilet and consequent dehydration. Other possible mechanisms could include the direct effects of inflammatory messengers on the blood vessels leading to dilation of the blood vessels and pooling of blood again with a drop in blood pressure. Other possible causes could include the effect of pain on blood pressure, the inability to eat due to gut symtoms leading to dehydration. This is not medical advice Joseph Murray MD
