<s>[INST] I recent and xray on my back and pelvic area because of a sciatic nerve flare up. I underside the information about moderate loss of disc height but not the significants of the statement there is a moderate amount of stool in the ascending colon. Could you explain the significants of that statement? [/INST] Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Loss of disc height indicates some kind of age related wear and of your intervertebral discs. You can go for an MRI scan for better evaluation. Stool in colon is of no clinical significance and is a normal finding and no treatment is required. Wishing you good health. </s>
