Thanks for your query.
You have not mentioned if chest X-ray was done; whether you have persistent mental stress/ signs of depression; acidity; weight gain in the recent past etc..
From the information provided, you bronchitis
could have been due to viral infection- which leaves one drained out for days/weeks.
Other causes which can explain your symptoms are, hypothyroidism
, mental stress; anxiety; depression and probably, Diabetes
(if you have diabetes in your family).Bloating
of stomach can be due to antibiotics, which can be eliminated by a course of Probiotics.
Consult your treating doctor, who will advise relevant investigations and prescribe appropriate/relevant treatment.
Hope I have answered your query.
