I have had my band now for four years and four months. I was the first of my family to get the band. My mother, daughter and husband got it done shortly after I did. I am the ONLY one of the four of us that has had verious "Issues" (for lack of a better word).
I have mild asthma and allergies and on occasion MUCUS is an issue. Ironically, I got on the internet to see if I could find information about the band itself and mucus. But you post caught my eye.
I just had a BM and noticed a white ball of mucus. As much as mucas can be an issue for me at least yearly, I have only seen it in a BM on occasion so I would not worry.
I have not been able to take anything but fluids for several days becuase of the mucus so I broke down and went to get Mucinex-D, I called the office, and was reminded that hot liquids help with congestion. Hope that helps!
