Hi my name is neha
My mom is being suffering from gas problem from past few years and around years ago when she had consulted a doctor in india he gave her this medicine name happy and that kind of gave her relief from the problem and from that time whenever she ate any heavy food from outside and whenever she had a stomach pain she use to take that tablet and its being 4 yrs now but since few months she is has got this stomach ache that even after taking happy she doesn't get any relief in march she consulted a doctor in dubai he did scanning and told that she has nothing its just fatty acid and for that she started going doing yoga and walk and this help her reduce wait but and it's a rapid reduc she lost almost 5 kgs in a month and but from past few days she finds swallowing food difficult she is not able swallow food properly and as she swallow's it she feels puke-ish and she doesn't feel like eating anything her food doesn't go inside only are these any symbols of cancer

I would not be concerned about the symptoms of cancer. Apparently at least one Physician has examined her and has not diagnosed cancer.

This could be anything - perhaps she needs to see another Physician.

What medicine was she given - I am finding that Viagra is called Happy Medicine in India - but this makes no sense.
