Hi-I’m new here. I have a question. My husband has rebound intracranial hypertension that developed after a cerebrospinal fluid leak was repaired (surgically and many blood patches). The standard treatment is diamox or another carbonic anhydrase inhibitor (ie. methazolamide), to reduce csf production. He has not started one yet, but will probably take methazolamide which is prescribed for glaucoma and has less side effects than diamox. The only time his symptoms improved was when one of his pt’s had him do balloon breathing . It seems similar to the bag breathing. My question is why do diamox and bag breathing help? I’m trying to wrap my head around it.
