<s>[INST] I'm 32 and weigh over 350lbs, recently I noticed my blood is lighter in color, brighter, almost orange.  I am relatively healthy aside from the normal aches and pains my weight causes.  I wanted to see if there is a reason for lighter blood or perhaps a change in diet due to having moved home? (yay home cooked meals lol) [/INST] Hi,Thanks for asking.Based on your query, my opinion is as follows.1. Lighter orange colored blood could be due to anemia.2. Evaluation of haemoglobin is necessary for further confirmation. Get a complete hemogram. Aches and pains along with fatigue is commonly due to anemia. 3. If you are suspecting a diet change and nutritional deficiency, iron studies along with vit b12 and folic acid assay would be necessary. Discuss with your doctor regarding getting these tests done along with a complete hemogram.Hope it helps.Any further queries, happy to help again. </s>
