[|Human|] sometimes the veins in my lips turn blue(especially lower lip). I am a healthy 49 years of age. I had my dr check it out (lips were not blue at that time). He listened to my lungs/heart /checked my circulation. He could not find a problem. I do have anemia and take daily iron supplements. I also take a proton pump inhibitor every day + pill for my Hashimotos disease.  I am eating healthy and exercising regularly. I am baffled as to what is causing this. It bugs me.
[|AI|]  Hi I did read your query and concern. It seems that you might be experiencing episodes of cyanosis in which bluing of lips occur. Most commonly it is due to a heart problem or a lung problem or a circulation problem. However, if all of these are normal, there is a condition known as methemoglobinemia caused by many genetic hemoglobin types. Does anyone in your family have the same problem? You can get it checked by an expert hematologist or if the symptoms do not cause any problems to you, you can send the blood sample overseas to Chat Doctor. Hope this help swish you a super healthy life ahead do let me know if you have any more questions for me.
