Bladder health covers a range of issues. Changes in frequency, small volume, pressure and initiation changes, bed wetting as well as control can all be a result of a bio-mechanical issues putting too much pressure on the bladder.
Poor bladder control is not something one needs to live with. Many bladder control issues can be helped by proper management of abdominal muscle tone, pelvic floor tone, bladder position, diaphragm function and movement and adhesions in the abdominal wall. Many people come to me believing their bladder problems are not a problem, its "just because I'm old" or "these things happen". These theories get thrown out when I see bladder control issues in all ages.
Please don't feel that just because many people have a symptom that its healthy or normal. Common? Yes. Normal?? I don't think so.
