Hi thanks for contacting HCM...
Here according to history it seems mostly viral flu or
gastritis ....It could be by ulcer also in stomach....
For few days follow below advise....
Take more fruits rich in antioxidant to boost immunity and prevent
constipation...
More water...
Hot water taken for upset stomach.....
For vomitting take
domperidone tablet...
Omeprazole 20 mg capsule taken for 2 week...
Avoid gastric irritants like
-smoking
-excess tea
-excess coffe
-alcohol
-meat
Oat rich in selenium , copper ,
vitamin E , zinc etc...help in soothing stomach ...so cooked oatmeal taken ...
Blueberry rich in vitamin c and having antioxidant property ...so good if taken....
If still condition not improve I would like to suggest USG for rule out organic cause...
Take care.
