I increased my use of water, fiber, and most importantly, supplemental senna, Miralax and stool softeners to prevent obstipation following a compression fracture.

I have now been diagnosed with hyponatremia and urged to immediately go to the ER for a saline iv. My complying resulted in sitting in the crowded ER for 6 hours last night, told they had no empty room necessary to insert the iv and just to quietly wait for an empty room, without drinking any water or risk death. I returned home, didn't die but discovered that I had likely induced this condition by taking too many laxatives and water.
Sounds unlikely but true. Subsequent calls = same answer - return to ER and wait.
