I have been having REALLY severe gas and bloating pressure for about a week now. I've taken gas-x without much relief. My diet has not changed much at all as I have been following weight watchers now for several months and have lost around 65 pounds. I am still overweight, biut like I said my diet has been quite healthy for months now. I do not believe my diet is causing this. It also started one day and quite badly. It did not slowly build up to bad proportions. I have added no new medications and have had my gall bladder removed several years ago. I have not had ANY problems with heart burn etc. since I started onto weight watchers. Is it possible a virus could be causing this, as I have been feeling generally tired and somewhat achy for the same amount of time. I felt great prior to this last week.......What could be causing this???
