POTS and Dysautonomia 101

from This EndoLife · host Jessica Duffin

Welcome to our continued series exploring the trifecta of POTS, MCAS and h-EDS/hypermobility,  and today we are basically doing a little POTS 101.POTS is a condition caused by a dysfunction of the autonomic nervous system. The autonomic nervous system is the part of our nervous system which governs involuntary actions of the body that essentially keep us alive and we don’t have to think about in order for them to happen, such as breathing, heart beat, blood pressure regulation, blood sugar regulation, digestion and so on.POTS is a type of dysautonomia (which is a spectrum of conditions and symptoms caused by this dysfunction of the autonomic nervous system) which causes a rapid increase in heart rate when going from sitting to standing. This change in heart rate is caused by pooling of blood in the lower body, which isn’t getting up to the heart and the brain like it normally should, resulting in the heart working harder to get the the blood moving. This reduced blood flow causes dizziness, breathlessness, feeling faint or fainting, palpitations and chest pain, and the change in heart rate can be measured.Affiliate PartnershipsDITTO - DITTO is a clinically studied PMS and PMDD supplement with 10 ingredients that target both the mental and physical challenges that come along with the menstrual cycle, developed by a PhD Nutrition Scientist.
