Hi there,as Flossie said,meno can be the cause of a lot of it. My bloating stopped when I cut out wheat but I had a test done,hence the reason I know it was the wheat. Weight gain is an issue too,women seem to gain it round their middle at meno time, I used to exercise like mad to shift it,nothing did,like you,injury means I can't exercise like I used to. Have you ever kept a food diary? It can be a pain but it may just show you what's causing the bloat
