Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. You may have a condition known as Hyperemesis gravidarum. This is an unfortunate situation where a woman develops severe reactions to a pregnancy and is in a chronic state of excessively suffering from nausea with frequent bouts of emesis (vomiting). Your bottom line to maintain your state of HYDRATION and NUTRITION although this is quite challenging. If you are not being followed prenatally then, you must get with an OB/GYN specialist since this condition can render you extremely malnourished and worse than that, severely dehydrated and this could compromise the pregnancy. Some cases become so severe that IV hydration and hospital stabilitzation by way of admitting patients for several days could be in your best interest. There s really nothing that truly stops this except delivering the baby. Stay hydrated at all costs and if you feel you cannot you must call your doctor or go the ER so you can be examined and potentially admitted or at least tanked up before going home. Hope I have answered your query. Let me know if I can assist you further.
