1. I have had this condition, where I have the constant urge to yawn, for over 7 years now. I am a healthy, physically fit 27 year old male. At first, doctors thought it was anxiety. I went to therapy for over 2 years and tried every medication known without any relief. It is so frustrating because every test that I have had (ekg, eeg, pulmonary function test, and so on) has turned out negative. The ONLY thing that has helped is when I DO NOT EAT sugar or carbohydrates. Sugar displaces the oxygen in the blood. I am about 50% better staying away from all sweets (candy, ice cream, cookies) and limiting my carbs. Let me know if you find an answer or medication. This is so frustrating. 2. I yawn hundreds of times a day. I cannot get a good, deep breath unless I make a big yawn. I must curl my tongue, open my mouth up wide and really breath deeply. This condition seems to come and go but has been really bad since the beginning of July. It started two and a half years ago. The feeling builds and builds until I can t take it anymore and must yawn to get relief. I want to know what this is, why this happens and if there is a diagnosis for this problem. Help!!!!! 3. Hi Heidi, - I think I have the same thing as you, I constantly feel like I don t quite have enough air, and so I constantly sigh and do big yawns but it never seems to satisfy! I ve had a million tests and everything s normal - they say its anxiety but I m a really relaxed person! The only diagnosis anyones given me is Hyperventilation syndrome, however I ve tried breathing exercises and nothing seems to work. I also sometimes feel like theres pressure on my lungs or something, do you get that? have you had any success in treating it? please please reply! you re the only person I ve found with anything similar!!
