Which are the symptoms of Dysautonomia / POTS?

Dizziness and Fainting
Gastrointestinal problems (e.g., abdominal pain, nausea, vomiting, constipation, diarrhea, etc.)
Tachycardia/Irregular Heartbeat
Hypotension/Hypertension
Problems regulating body temperature
Brain Fog

Light headedness and brain fog. If any I'd get rid of those two. Along with nausea these very much limit a person to do daily activities as a "normal" person would.

Exhaustion, low blood pressure, migraines, inability to eat, hot/cold intolerance, increased heart rate, dizzyness, fainting, brain fog.

Dizziness, fatigue, sweating,

Tachycardia, chest pain, low BP and syncopal episodes. Nausea, heat Intolerance, dizziness, fatigue and trying to find a doctor that knows how to treat your condition.

The dizziness and the fainting are the worst symptoms

The chronic fatigue and tachycardia.

Fog brain and fatigue are the absolute worst. It keeps me from doing things and it makes me look really dumb at times because I can't remember things.

The fatigue is defiantly the worse.

Chronic fatigue, headache, GI issues

For POTS, NCS, OH, and neurally regulated hypotension: The most obvious would be if someone tends to pass out or come close to passing out (lightheaded/pre-syncope) when they're getting out of a shower or hot tub, or just going from lying down to standing. Sometimes this pre-syncope might show as a less obvious headache/subtle lightheadedness. Not everyone passes out though and for many it can improve over time if you can find the cause or what might be called the subtype or other comorbidities you have. You might notice you just become really fatigued much sooner in the day and all you did was wait in line somewhere, eat a carby meal, or just happen to get up and down out of your desk a lot. If you notice a lot of major systemic issues or passing out you'll want to start with a poor man's tilt table test and keep an eye on your pulse. If you notice your pulse is a little off from the normal range you'll want to see a cardiologist and make sure you don't have an arrhythmia or anything structurally problematic that could be causing this. Fatigue is a big one, not registering temperature correctly is another one, lightheadedness and brain fog are another big two. Your pulse going up +40 or more when you stand also is CONSTANT even if you don't feel that bad sometimes when you're standing or walking, it's the one consistent physiological feature.

For gastroparesis: you'll feel starving, go to eat, and after only a bite or two feel so full that you might throw up if you take another bite. You also will feel hypoglycemic even if you just ate and should be fine, have a general feeling that none of your food is really digesting (or seeing it in your poop or vomit), and any scans might show you're constipated even if you don't feel like it.


SFPN, also how this relates to POTS and sometimes autoimmune diseases or genetic anomalies: I could write a book on this one so if you have questions, do your homework first and then ask me.

Tachycardia (Rapid Heart Rate) - which increases on changing posture - from laying down to sitting, to standing, sometimes from shifting in bed or in the lounge chair you are sitting in. Any exertion can change your heart rate anywhere from 30 to 100 or more BPM which can be quite scarey. Chest pains and feeling like you are having a heart attack is not unusual and it is difficult to get doctors to take you seriously once they know you have POTS and you present with chronic chest pains, severe dizziness, pooling of blood in the legs and hands, etc - they kind of brush you off and go 'its just a POTS episode' - the scarey part is that there is that one time it may NOT be a POTS episode!
There are a lot of POTS patients who are too dizzy and too weakened to even walk and spend their entire time in a chair or with a feeding tube, while there are others who will be able to ALMOST function on a good day and seem 'normal' to the general public - however the 'general public' dont see what it took to get ready to go out of the house, or that it then takes a few days to a couple of weeks to get over that short trip to the grocery store or the pharmacy.
The crazy part is that POTS seems to cross over a lot with things like Fibromyalgia and there are bits of each that are the same and bits that arent - so it is important to know which is which and actually recognise your symptoms and note them down at times - particularly if you have a 'strange one' come up to discuss with your treating professional.
My personal most limiting symptom is the dizziness, the breathlessness and the tachycardia - I also get brachycardia which also interferes with my breathing and my heart rate can range from 35 to 145 within the space of about 5 minutes at times..... that is NOT fun.... the body pains and chest pains, not being able to stand up in a shower (warm water hits and the BP drops and so do I - so shower chair isnt a 'want' it is a 'need'), and as soon as the weather changes and in particular warms up - I am in big trouble and live with the air conditioning on all year round almost.
