Your intestines and kidney are separate systems. They do not talk to each other.
Renal problems do not cause intestinal bleeds, they cause imbalances in your blood chemistry and fluid volumes. You feel lousy and hold onto fluid and get puffy.
Since you are concerned enough to ask, I assume this bleeding is consistent and significant enough to get your attention. If you are seeing red blood, then it is a lower intestinal bleed. It could be an internal hemorrhoid, diverticulitis, or something else. You need to see a doctor for a few reasons.
- the bleed could get worse, a lot worse, if it is not treated. Trust me when I say you do not want to experience worse.
- the bleed may have been going on slowly for a long time and you didn’t notice until now. You could have severe anemia due to slow but steady blood loss. This needs to be corrected and the bleeding stopped.
I hope you have already gone to your health care provider and are now getting treated. If not, please go now so you are safe and healthier.
