syncope

[sing′kəpē]
Etymology: Gk, synkoptein, to cut short
a brief lapse in consciousness caused by transient cerebral hypoxia. It is usually preceded by a sensation of light-headedness and often may be prevented by lying down or by sitting with the head between the knees. It may be caused by many different factors, including emotional stress, vagal stimulation, vascular pooling in the legs, diaphoresis, and a sudden change in environmental temperature or body position. Also called fainting.

syncope

Neurology A transient loss of consciousness not explained by other altered states of consciousness in the history of the Pt, often linked to cerebral ischemia; fainting, loss of conciousness or vertigo due to a transient arrhythmia, cardiac conduction–heart block, or neurovascular tone. See Carotid sinus syncope, Deglutition syncope, Neurocardiogenic syncope, Seder syncope, Seinfeld syncope, Sushi syncope.

Patient discussion about syncope

Q. i am 12 and my hair is falling out what do i do? there is like a hair ball in my tub

A. First of all you are going through puberty and the hormonal levels in your body are changing, this could cause accelerated hair loss that will go away. However, if you feel like you are having severe hair loss you should go and get blood tests for the evaluation of several vitamin defficiencies (B12, Folic acid and Iron), that can be the reason. Soemtimes a lack in our nutrition can be the reason for losing hair.

Q. I found out 1week ago i was 6wks pregnant and lastnight i passed a 1/2dollar size clear ball did i miscarrie? the ball was clear,soft and jellie like and it came w/a lot of blood but i didnt see no signs of a baby or anything like that

A. Possibly, but not essentially. In this age the embryo is quite small (several millimeters), so you may easily mistaken it. My best advice is to consult a doctor (e.g. gynecologist) so an US or other test can be done to accurately diagnose a miscarriage.

Take care,
