Autonomic Nervous System (Definition)

The autonomic nervous system is part of the peripheral nervous system. It is ‘autonomic’ because it does not require voluntary thought to function. The autonomic nervous system is divided into the sympathetic and parasympathetic nervous systems. The sympathetic system manages “fight or flight” responses and the parasympathetic system acts as a counterpart that manages ...Read more

What are some autonomic reactions from stress?

What are some autonomic reactions from stress?

'fight or flight': Humans have built-in emergency responses to help us survive life-threatening situations. A combination of stress hormones (epinephrine [aka adrenalin], cortisol, etc) & high sympathetic (autonomic) nervous system output results in increased pulse & bp, shunting of blood toward the vital organs, faster reaction times etc. Unhelpfully, we react to stress this way too, which wears out our bodies. ...Read more

Does the autonomic system control goosebumps and shivering?

Does the autonomic system control goosebumps and shivering?

Yes: The best way to understand the autonomic system is to change the word to "automatic". It controls things that our body needs to be in charge of like increasing the heart rate when we need to "flee or fight", sweating, shivering, how oily or dry our skin is as well as those things you mentioned. These are the result of years of genetic changes from evolution to improve the survival of our species. ...Read more

Scleroderma and autonomic nervous system, how are they related?

Can be neurological: We can see this with scleroderma and other connective tissue dieases. Your physicians can help to evaluate for this but most of the consideration is clincial with very few specific testing. This occurs because of the associated vascular changes with scleroderma adn otehr connective tissue diseases. Vasculitis can also occur. ...Read more

What are the difference between central nervous system and autonomic nervous system?

What they control: The central nervous system refers to the brain and the spinal cord.

The autonomic nervous system is a part of the peripheral nervous system that is involved in processes related to heart rate, sweating, blood pressure, and other processes that we don't think about, aka the name "autonomic". Autonomic nervous system disorders include fainting, fast heart rate, fatigue and sweating disorders. ...Read more

Can I take hydroxycut gumimes with autonomic dysfunction? My Dr not calling me back so I guess it's ok to try it

Not shown to be: effective by FDA. Plus most products contain caffeine (discuss with your doctor weather or not you can take caffeine with the type of autonomic dysfunction you have.)
In 2009 Hydroxycut was pulled from the shelves because an ingredient caused liver failure and rhabdomyolysis. They have re-introduced a new formula since then but as I should remind you there has been no formal scientific study ...Read more

Have you ever heard or seen a patient suffering with an Autonomic dysfunction, which seems to be related directly with their bowels?

Yes: But just to clarify what you're really asking. First, I'm a neurologist. I see lots of things which appear to have NOTHING to do with the nervous system but then, they do. So that's not so new....but are you asking whether or not I've seen a case of Autonomic Dysfunction manifest SOLELY or FIRSTLY as Bowel dysfunction? That's an interesting question.

If blood pressure goes up a little when standing up rather than dropping, is this a bad sign or autonomic problems? Male 22. I heard it drops by 10?

If blood pressure goes up a little when standing up rather than dropping, is this a bad sign or autonomic problems? Male 22. I heard it drops by 10?

Not necessarily: Often BP does drop a little, transiently at least, upon standing. However, the lack of a drop doesn't mean anything wrong. You are a young, and i assume healthy, male. If you have good muscle tone and development combined with a healthy heart and circulatory system, minimal or no drop in BP would not be unexpected or cause for concern; unless you are having other cardiovascular symptoms. ...Read more
