Patient discussion about emesis

Q. I'm scared to be pregnant... vomiting and to give birth...Please tell me it's fine!!

A. since how long are you pregnant? it seems that it just started. if you vomit a lot it is imperative that you drink enough water - still water like Vitel, Vichy, L'eau d'Evian that you get in your country and find bottles in glass - not in plastic! Plastic is anorganic and can't be assimilated in our bodies. there is no reason to be scared if you vomit. this means that you don't drink enough water. i know this. believe me and you will see that in the next days you will not vomit anymore. just keep me informed please!

Q. Dizziness and vomiting after a car accident, what can it be? Two days ago I was in a car accident and a car rear ended me. I went to the emergency room and was checked up and was discharged saying all is ok. Following the next morning I woke up and the whole room was spinning. I feel nauseous and find it hard to do daily activities. What do I have?

A. It could be Vertigo. The sudden onset of vertigo usually indicates a peripheral vestibular disorder.
Symptoms of benign paroxysmal positional vertigo (BPPV) usually last a few seconds to a few minutes and are intermittent (i.e., come and go). They also may include lightheadedness, imbalance, and nausea, usually as a result of a change in position (e.g., rolling over in bed, getting out of bed). Please consult your GP about these symptoms.

Q. my friend recently told me that she throws up from time to time and it helps her balance her weight I told her I think that’s what bulimic girls do, but she insisted that it wasn’t something she can’t control or that comes after eating bursts (which she doesn’t have). It still seems wrong to me, but I would like to hear other’s opinions.

A. bolimic girls try to avoid eating. then they get so frustrated that they eat like crazy and then feel guilty and threw ups. it's a bad condition that needs to and can be treated.
