I have had low level dysautonomia all my life, including this breathing issue... during chemo I was formally dx'd with dysautonomia and following chemo the breathing issue got dx'd as Central Apnea (with Central apneas, hyponeas, bradypnea episodes)... it was happening at night and during the day, so I'm on CPAP at night... finally cracked the daytime centrals using salt 6g, calcium, magnesium, glutamine, taurine, citrulline plus low salicylate as salicylate levels sent my centrals soaring... really tough one to crack... anyone having daytime breathing dysreg I'd strongly suggest they get to a sleep clinic as its highly likely its happening during sleep too... and that can make ill health much more progressive and precarious... central apnea in sleep can risk heart attack, stroke and increases cancer mortality risk not to mention that hypoxia damages every cell in the body and brain dysfunction. I've had the breathing stuff since age 2 (had measles and mumps then which may have set it off) but it got worse a few years ago, then unmanageable after chemo. I seriously think my cancer was faster and worse because of untreated central apnea as part of my dysautonomia. Donna
