My mum is 60 years old and has severe constant vomiting and drowsiness for the past 3 weeks.She is a diabetic,has ashtma and suffers from high blood pressure.We have taken her to two different hospital now ,they have done xrays and bloodtests and is unable to find anything wrong aside from a little infection in the chest.The doctors has also given her various antibiotics but she cannot even keep that down.She is furthermore suffering with constipation and passing alot of gas.

Please advise.
