A member asked:

Why do i get so tired, to the point of falling asleep anywhere anytime, before i poop. i have ever since 2009 when i had a tumor removed.

Tired/poop: Some things in te autonomic nervous system change before you defecate. Your parasympathetic nervous system dominates in this instance. This part of the nervous system slows the heart rate and can decrease the blood pressure. There is a disorder where people pass out after defecation (defecation syncope). Try to see if your heart rate and blood pressure drop at this time with a home BP cuff.
