Hypotension

This is what I had found from Wiki. Thank you Wiki. Love Wiki so much. lol...
These are only some. not all... if you want to know more, go to this wikipedia.org and search yourself... haha.

What is it?
In physiology and medicine, hypotension refers to an abnormally low blood pressure. This is best understood as a physiologic state, rather than a disease. It is often associated with shock, though not necessarily indicative of it. Hypotension is not hypertension, which is high blood pressure, the opposite of hypotension. Hypotension is a fairly rare problem, hypertension is a much more common problem. Hypotension is usually not a serious problem, although in some cases it can be life threatening.

MECHANISM AND CAUSES
Reduced blood volume, called hypovolemia, is the most common mechanism producing hypotension. This can result from hemorrhage, or blood loss; insufficient fluid intake, as in starvation; or excessive fluid losses from diarrhea or vomiting. Hypovolemia is often induced by excessive use of diuretics. (Other medications can produce hypotension by different mechanisms.)

SYNDROMES. (some parts I comprehend, some parts I don't. Head is not helping...)
Orthostatic hypotension, also called "postural hypotension", is a common form of low blood pressure. It occurs after a change in body position, typically when a person stands up from either a seated or lying position. (some may experience it, I do. Always. But today's experience is not normal. It was worse... Really) It is usually transient and represents a delay in the normal compensatory ability of the autonomic nervous system. It is commonly seen in hypovolemia and as a result of various medications. In addition to blood pressure-lowering medications, many psychiatric medications, in particular antidepressants, can have this side effect. Simple blood pressure and heart rate measurements while lying, seated, and standing can confirm the presence of orthostatic hypotension.

Neurocardiogenic syncope is a form of dysautonomia characterized by an inappropriate drop in blood pressure while in the upright position. Neurocardiogenic syncope is related to vasovagal syncope in that both occur as a result of increased activity of the vagus nerve, the mainstay of the parasympathetic nervous system.

SYMPTOMS
The cardinal symptom of hypotension is lightheadedness or dizziness. If the blood pressure is sufficiently low, fainting and often seizures will occur. (well, I was about to...)
Hypotension, depending on one's own body chemistry and genetics, may often cause mild depression (damn! its really depressing i tell you...), mostly in regard to taking other medications which do not fit one's personal unique needs.

FYI: those in italics are what I personally experienced 2 yrs ago and today! Bloody hell...

See hanafi... your GF's life is threatened. Haha... But no worries. Mine is not at the severe stage yet. But its obviously not at the 'slight' stage. its some where around 2-3/5 since I have been experiencing dizziness when changing posture and when not. The shock part is true. And the irregular heart beat too. I can feel it.

Just so you know, the reason why my head is not really spinning now is because I had eaten. Gonna eat again and take some medication. My mom will buy me some vitamin B. Hope its like sakatonic ABC. you know got flavours.... mmmm yummy...

K so long... :D... Oh yeah 16 more days! (hint: Click :me:... hehe)
And 29-30 i'd be going melacca. Cant wait. Confirm on the 31 at school I'd be half awake. Or best still. At home sleeping. LOL... can't wait larrr. Get out of this boring vacation. Wait. Hope this hypotension won't hit me again!
Pray,Pray,Pray....
