You see, I was admitted for super-low blood sodium. Hyponatremia can be dangerous and it is what caused my headache, confusion, and dizziness. That was why we called the ambulance in the first place. I had a long stay for the simple reason it's not a great idea to raise the sodium level too quickly. In fact, once during my stay, my IV was switched to sugar as it'd been climbing in a manner that was apparently too fast. A too-rapid correction of sodium can cause osmotic demyelination syndrome (ODS), a form of brain damage.
So, I was able to spend the entire week in a vastly-overcrowded Royal Columbian Hospital. Every employee I met, was dedicated and worked at about 112%. I worry they will burn out and quit in astonishing numbers. I'm thankful for the care and attention I received at every step along the way. My problem is now corrected so I'm healthier than I've been for years.
I was on Hydrochlorothiazide for blood pressure control for eighteen years. It worked swimmingly for that purpose as over the last few decades my bp has been around 115/77. The drawback to thiazide diuretics is they can deplete one's body of important blood components. And I was basically dehydrated for two decades. It finally caught up to me when I took a breather from them for a few days and then restarted. This is far too common a problem.
I've moved to a different drug for high blood pressure.
