Hi fundo,Welcome to Healing Well! When you say your breathing was difficult, do you mean that acid had migrated into them, causing damage? Have you seen a pulmonologist?
What does your surgeon say about this problem persisting? I will say this. While most of the healing and adjustment to your GI changes occur by 6 months, the healing continues throughout the first year. I even found fine tuning continued into the second year.
Hopefully somebody will be by to share more information and support. I also had difficulty with breathing pre-op, but my issue was caused by reflux creating very bad asthma symptoms. My lungs took about two and a half months to improve.
Glad you've joined the forum!
Best wishes,
Denise
