Question 1

why do people with motion sickness throw up?

Accepted Answer

Autonomic n s: Vertigo is one of the many conditions that causes imbalance of autonomic nervous system function. As a result parasympathetic function through vagus nerve increases giving fist to contraction of stomach muscle and vomiting. Blood pressure, heart rate can change too.

Question 2

why do i throw up when i get motion sickness?

Accepted Answer

Vomit center: There are several neural connections present to help maintiain our balance.  Unfortunately one of those balance connections goes through the "vomit center" in the brain stem.  Motion sickness is due to sensory conflict (incongruous information from different sensory systems).  When this sensory conflict occurs, it triggers an assortment of responses of which vomiting is one.

Question 3

major airplane motion sickness. have to lean against window with eyes closed. if open eyes everything spins and throw up. why?

Accepted Answer

Loss of reference: You are in a tube, hurtling through space...You have very limited reference points for your eyes to say are stationary, which conflicts with messages from inner ear and some from spine. Confused messages = dizzy/nausea. If over-the-counters don't help (dramamine (dimenhydrinate) / bonine), then see dr for prescription help (transderm-scop; compazine; zofran; ativan).

Question 4

why does motion sickness trigger vomiting?

Accepted Answer

Kidney energy: According to meridians theory kidney meridian is the one that influences ear area. Kidney energy when is normal energy flows up and down the spine. During disharmony this starts flowing sideways and causes disruption to stomach energy causing gaging and vomitting. Interestingly with pyelonephritis - kidney infection vomiting is the main symptom sometimes.

Question 5

Accepted Answer

Cyclical vomiting: You probably have cyclical vomiting of the adult as a carryover from your youth. The exact cause of the syndrome is unknown but some people feel it may be a form of migraine and in fact some results have been achieved with migraine medication.

Question 6

what causes motion sickness, nausea, vomiting, dizziness  and migrain headache?

Accepted Answer

Bad migraines?: Well bad migraines can cause those things but i would see a neurologist if your headaches are that bad!  one, it is important to rule out other causes and two, you could undergo migraine treatment if that's what it is. Good luck!

Question 7

iv dramamine or iv phenergan (promethazine) for.motion sickness?  which is better if the person is already actively vomiting

Accepted Answer

Hospital: If you are at the hospital then let the hospital decide that. Do not try this yourself as you can risk other complications. Usually though IV Phenergan (promethazine) is used most of the time for nausea where as dramamine is usually taken 30 minutes before known motion sickness.

Question 8

what can i do/take instead of dramanine for motion sickness (nausea + vomiting) while breastfeeding? (i need something guaranteed to work!). thank you

Accepted Answer

Scopolomine patch: A scopolomine patch is relatively safe for a short period (3 days).

Question 9

what would work better for motion sickness once vomiting has started... iv benadryl or iv phenergan (promethazine)?

Accepted Answer

First : Once vomiting started nothing can be given orally, just IV or intra muscular. Both drugs are histamine blockers bit have a relaxing effects too. I would try with benadryl (diphenhydramine). If in i would dilute it in saline and inject very slowly. Hope it will help. Did you try scopolamine patches before being exposed to motions?

Question 10

how long for meclizine to start working if taken on an empty stomach after motion sickness (severe nausea no vomiting) already started ?

Accepted Answer

Within an hour: Meclizine works within the hour for most patients I treat in the ED.  Some a little longer, some a little shorter.  IF this is the cause of your motion sickness.  There are many causes of vomiting in young adults and unless you in a car or on a roller coaster, motion sickness is probably not the diagnosis. Call your doctor and make an appointment.
