This short clip has been taken from Q&A session of our 1st live Webinar on Introduction to Diabetes Mellitus. We will have 23 more webinars on Diabetes Mellitus each on every Sunday.
In this webinar a student asks a question about Orthostatic Hypotension and in Diabetes Mellitus.
Orthostatic Hypotension:
When a person stands up from lying down position, the blood gravitates into the lowers parts of the body. This is quickly followed by sympathetic firing that constricts the blood vessels in lowers parts of the body thus providing the sufficient blood to the brain and maintaining the sufficient venous return to the heart.
In Diabetes Mellitus due to Autonomic Neuropathy, the sympathetic nervous system mediates vasoconstriction of blood vessels of lower parts of the body, thus venous return to the heart is reduced and blood pressure falls. So, enough blood does not reach to the brain leading to fallouts/fainting episodes. This is called Orthostatic Hypotension
