today i didn't went for bio extra lesson, den must produce mc.. grr... so i went to the doctor.. and he says i got low blood pressure.. omg.. "People who have lower blood pressures have a lower risk of stroke, kidney disease, and heart disease." omgomg!! all this from a medical website.. "or example, if insufficient blood flows to the brain, brain cells do not receive enough oxygen and nutrients, and a person can feel lightheaded, dizzy, or even faint. Going from a sitting or lying position to a standing position often brings out symptoms of low blood pressure. This occurs because standing causes blood to "settle" in the veins of the lower body, and this can lower the blood pressure. If the blood pressure is already low, standing can make the low pressure worse, to the point of causing symptoms. The development of lightheadedness, dizziness, or fainting upon standing caused by low blood pressure is called orthostatic hypotension. Normal individuals are able to compensate rapidly for the low pressure created by standing with the responses discussed previously and do not develop orthostatic hypotension." lucky i not so jia lat.. Loo: go see doctor ar.. in case.. ok? always headache or feel dizzy not good de..
