Extra information provided by this PSP
Original uncertainty examples Is there an effective treatment for ptyalism? ~ Is there anything to reduce the excess saliva that comes hand in hand with HG? ~ One of the most distressing symptoms of HG for many women is the heightened sense of smell. Is there a medical way to target that symptom in particular? ~ The sickness and nausea is obviously a big part of HG. But how do we treat the less talked about effects including extreme tiredness, no energy, headaches, dizziness, breathlessness, confusion, being unable to stand/endure movement or motion/listen to conversations/music without feeling like you are going to be sick or faint? ~ How can the other symptoms be reduced (i.e. smell sensitivity, excessive saliva, extreme fatigue, recurring UTIs). ~ Is there a way to control the extreme sensitivity to smell, which causes so much agony? ~ Is there anything that can be done to dull the extremely heightened sense of smell that a lot of HG patients suffer with? As I honestly think it would have helped with the severity of the constant nausea in my case.
