I was told those very same words by many doctors for several years. DON'T believe it! Low blood pressure is caused by hypothyroidism. I recently discovered that over a prolonged period of years, it will enlarge the heart. What it actually means is that the heat muscle isn't as strong as it should be (the medical field calls this Low Cardiac Output
because you probably have insufficient T3 thyroid hormone available to properly regulate cardio- vascular funtion. Taking thyroid hormone replacement (a T3/T4 combination) will correct both low and high blood pressure problems. Have your doctor (or do it yourself if you have a BP monitor) take two readings. Once sitting down and then immediately after standing up. If your blood pressure drops when you stand, (it should go up) my diagnosis is correct (they call this orthostatic hypotension). If you were to ask most physicians if what I'm telling you is true, they will probably tell you I don't know what I'm talking about.
Do some research on the Internet about hypothyroidism and see if you have other symptoms that you can relate to (you'll have to compare with many sources because hypothyroid symptoms can be almost anything that isn't infectuous related).

Doesn't this also create a problem? Is there anything I should do or watch for? I gave blood once and passed out right afterward...could this have been the reason? Is there anything anyone can do to raise blood pressure? What causes it to be so low? Thank you all so much for ANY advice!
