Multi-Issue Concern: Rectal bleeding of any sort is a concern. There are numerous causes including parasitic infections or tumors. Unchecked it can lead to nutrient deficiencies, iron loss and anemia. Anemias can lead to headaches, fatigue and dizziness. Typically stool testing, bloodwork and nutrient deficiency screening are done to address these issues. See your physician for assistance.
