Is it morning
sickness, nausea and
vomiting of
pregnancy or emesis
associated with
pregnancy?
Pregnancy Sickness has been around for as long as
women have been pregnant. It is estimated that between 50% to 80%
of pregnancies bring with them the sickness that can start and end at any time
of day or night - sometimes not end at all. For decades the world of medical
science has sought an answer to it, but this has been a demanding task as no-one
in their right mind would attempt tests on a Mother and Fetus.
ResearchAsking a pregnant woman to try a new product is unsavoury for
obvious reasons - why should she be the guinea pig? Hence nothing much has
really progressed in terms of finding a solution to the problem, that is until
now. Now we have a better understanding of which bodily organs are involved in
the process of being sick - what the medical profession calls "EMESIS".
A new understanding of the pathways used in Emesis
Does it drive you crazy to
receive great advice intended to stop you from vomiting - that involves
swallowing something? If you manage to swallow it - how long is it going
to stay with you anyway?

Nausea and vomiting of pregnancy shares many
characteristics with motion sickness, a vestibular dependent phenomenon.
A number of physiologic changes that occur in normal pregnancy are also known to
accompany nausea and vomiting in patients with motion sickness and
certain vestibular disorders. This chapter summarizes some shared features of
both phenomena. The unmasking of subclinical vestibular disorders may account
for some cases of hyperemesis gravidarum. Hormonal effects on neurotransmitter
function may also play a role in nausea and vomiting of pregnancy and in some
vestibular disorders; however, the specific neural mechanisms of nausea and
vomiting have not been identified. Until the neurochemical processes underlying
these phenomena are understood, prevention and management will remain in the
domain of astute, but so far limited, clinical observation.

Physiology of chemotherapy-induced emesis and
antiemetic therapy.
Predictive models for evaluation of new compounds.

The physiology of emesis has been
studied for several hundred years, focusing on the different centres involved
and the mechanics of expulsion. The vomiting centre receives inputs from various
emetic detectors such as the gut, the vestibular labyrinths and the
chemoreceptor trigger zone. Emesis is a common disabling effect in motion
sickness, postoperative conditions and in radio- and chemotherapy. Our current
understanding of the mechanisms has been provided mainly by the recent
introduction of serotonin 5-HT3 receptor antagonists into therapeutic use.
Nevertheless, despite the considerable advances made in the understanding of the
different pathways involved in emesis, there are number of areas that still
require experimental investigation. Different animal and human models are
available to study the physiology of emesis and to evaluate the antiemetic
activity of new compounds, but they need to be predictors of clinical
situations. Language : English

to offer advice on a variety of products and they have been supplied information
covering our products as we featured in Pharmacy Magazine and Pharmacy Products
Review in June and July 2001.
They can also offer leaflets on the subject of
Vomiting. The following leaflet can be obtained at a pharmacy displaying

- Common Causes of Vomiting:
The most common reason for vomiting is reflex vomiting due
to conditions such as
stomach inflammation (gastritis), stomach ulcer and a narrowing at
the stomach's exit, called pyloric stenosis. Other conditions
that produce vomiting include
appendicitis, bowel obstruction and pain from kidney
or gallstones. Certain drugs such as aspirin or ibuprofen
may also cause stomach irritation and vomiting in susceptible people.
Motion sickness and Meniere's Syndrome - which affects a part of the ear
known as the vestibular part - are two other well known causes of sickness
and vomiting. Vomiting can also be a feature of many serious
illnesses including
various brain lesions caused by infection or swelling. It is also
common symptom of migraine and is also associated with psychological
conditions such as hysteria,
anxiety and nervous tension.
