Hi,I am Dr. Robert Galamaga (Hematologist). I will be looking into your question and guiding you through the process. Please write your question below.
Blood In Dark Color. Have Healthy Food Habits, Life Style. What Is The Reason?
My blood has been very dark in color lately. I am a bit concerned because I have not changed any of my habits. I still eat regular and as healthy as I can, I guess. I exercise daily and take regular vitamin supplements. I am a 25 year old man and I am bothered by my lack of knowledge in regards to the issue at hand. Please offer any information or insight that you can. Your time and input will both be greatly appreciated.
Hi,
How did you assess that your blood is dark. Usually when injury occurs the blood will be red in color because it is arterial blood which contains more of O2. Suppose you are giving blood samples for investigation it will be dark in color because it is venous blood which contains more of CO2.
Those who have bronchial asthma or a smoker may have dark colored blood because of less % of O2 absorption in the bronchial passage. Where as you say in all aspect you are normal. even though O2 & CO2 monitoring machines are available better you check up your O2 saturation in the Pulse oxi meter within a mt. you will find out your O2 saturation which should be 90 and above.
Best wishes
Hi, thanks for posting a "Q" to H .C. M. C.
Bright red color is the color of blood of human. Slight dark may be with extra red bright as these are variations.
In my carriers I have seen dark color blood in patients having allergy ( bronchial asthma, TUBERCULOSIS & some chronic infection.)
All above mentioned diseases have symptoms so in your's case nothing is wrong so need not to bother about the color og blood and enjoy the life.

Hallo,
Blood is a lighter color when carrying Oxygen and darken when carrying Carbondioxide.
If the blood was dark, it was probably carrying carbondioxide at the time it was taken. If it's black, it is polluted with something or your kidneys / liver are having problem.
