Orthostatic Hypotension
Someone may pass out when they stand up due to a condition called orthostatic hypotension. This occurs when blood pressure drops suddenly upon standing, leading to reduced blood flow to the brain. Factors such as dehydration, prolonged sitting, or certain medications can contribute to this drop in blood pressure. When the body fails to quickly adjust to the change in posture, it can result in fainting or lightheadedness.
The most common symptom of coccydynia, irrespective of the cause of the condition, is pain when sitting, or when rising from a sitting position. If the condition lasts long enough, the patient may even experience pain when standing or lying down.
What position is blood pressure normally the highest and lowest?If a person was sitting, reclining, or standing, which position would cause the blood pressure to be highest and lowest?Also, if there was an increase in blood viscosity, cardiac ouput, and diameter of the arterioles would this constitute to an increase in blood pressure as well?blood pressure (BP) is usuall lowest standing position and highest in supine (reclining) position. This is because the blood return to the heart is decreased when standing.http://www.bloodpressureinc.com/what-position-is-blood-pressure-normally-the-highest-and-lowest/Exercise is at its highest when we exercise and lowest when we sleep.
A person's blood pressure will change slightly depending on their position. When you take someone's blood pressure, they should be sitting up, with their legs straight in front of them, not crossed. Laying down will give a lower blood pressure.

It should be positioned on the upper arm just above the crease of the lower arm.
Orthostatic hypotension is a temporary and short-lived condition of low blood pressure, sometimes occurring when a person stands or sits upright from a sitting or recumbent position; it can result in light-headedness or fainting.
When people with this condition move from a lying position to a standing or sitting position, the sudden pooling of blood in the legs may cause a temporary decrease in blood circulation to the brain, causing a faint.
When a person has difficulty breathing in any position except sitting or standing, the condition is known as orthopnea. This typically occurs in individuals with heart failure or certain lung conditions, as lying down can exacerbate fluid buildup in the lungs or compromise respiratory function. Patients often find relief by propping themselves up or using multiple pillows while sleeping.
Depends on the medication. If this is extremely unusual, it could be a sign of many things. Call his cardiologist and keep a log throughout the day of his heart rates. Also, ask him about any dizziness, etc, especially when standing from a sitting position. Any lightheadedness--tell his doctor you want him seen TODAY. Could be a sign he needs a pacemaker.
In most cases, body position has very little effect on blood pressure. In many cases, the blood pressure will rise a little as a result of the heart rate going up when sitting or standing compared to lying down. Some people have an imbalance in their Autonomic Nervous System, which controls constriction and dilation of blood vessels and may find that their blood pressure is lower when standing as opposed to when lying down or sitting.
