Hello dear,I understand your concern.In my opinion sickness is routinely seen in pregnancy but some might have it severely.Dont worry .It will subside spontaneously after a month or so.But if it is limiting her to do her daily activities then you might need IV fluids with multivitamin injections.So discuss with your doctor.Ginger tea and dry toast in morning might be helpful.Take food in small quantities every 2 hourly.Take adequate fluids upto 3 litres including fruit juices,coconut water. Best regards..Dr srilatha
