I was diagnosed with UC Surgery 2010 Mt Sinai Hospital I developed a cough in 2015. I went to my md sent me for x-ray treated me for bronchitis. I had an annual check up by my gastro at Mt. Sinai I told him about the cough he told me to see the lung Dr. I made an appt. on Long Island went thru every test you can think of couldn't find anything wrong but in the mean time I was coughing this dark yellowish thick sputum for about a year. The lung Dr. told me to go back to my gastro in the city. My gastro in the city told me to see the lung Dr. at Mt Sinai. I also have an immune deficiency from UC. I brought all my tests and MRI they I had done on Long Island. Within 20 minutes he diagnosed me with bronchiectasis. He told me 20% of people with UC could end up with this lung disease. He gave me an Aerobika breathing apparatus to use every day. No medication with it. I have another apt with the Lung Dr. next month. I am still coughing. The machine helps get some of the sputum up. I don't know if this helps you but it is something to ask your Dr. about. Please let me know how you make out. Grace
