Would drinking excessive coffee, such as 4-5 20oz cups (100 fl.oz. / 3 L total) per day, reduce blood hemoglobin content?

Are there other digestion or gastric issues related to drinking excessive coffee?

  • Golly, for my consumption level, I certainly hope not. 100 fl. oz. / 3L of coffee is certainly not modest but not completely crazy. What makes you think this is the case? Would you please edit your question to link to citations or references to suggest why you suspect that coffee might impact hemoglobin levels? – hoc_age Mar 30 '17 at 4:35
  • Please focus on one topic per question; would you kindly split the other topic about digestion/gastric issues into a separate question, annotated with specific concerns? – hoc_age Mar 30 '17 at 4:36
  • @hoc_age , I drink atleast 3 large cup of coffee... and the topic is same related to health ... – goofyui Mar 30 '17 at 12:17
  • @goofyui There are technically two questions in your post, one about blood hemoglobin content effects and another about gastric or digestive system effects of excessive coffee drinking. Although both about health, they are two different questions and should strictly be separated. – Shiri Mar 30 '17 at 12:59

coffee reduces iron uptake. parts of hemoglobin are comprised of iron. if hemoglobin becomes low the oxygen rate to other parts of your body decrease. causing low energy and fatigue. the low iron could also cause anemia.

  • Thank you, I will control my coffee intake – goofyui Nov 19 '18 at 13:04
