Nausea and vomiting in pregnancy is a common condition, affecting up to 80% of pregnant women, but yet it remains vastly under-researched and under-appreciated.
‘Morning sickness’ as a description has been around for many years, but it misrepresents and trivialises the condition. There are many possible causes of the condition, but precisely why it occurs is still largely unknown.
Dr Roger Gadsby, MBE, GP and Associate Clinical Professor at Warwick Medical School, has been researching the condition for nearly 30 years, and in 2002 helped to set up a small charity called Pregnancy Sickness Support to give information and support to women suffering from the condition.
"In 1993, I worked with others to publish a ground breaking paper of the condition in 363 women from my practice. This paper has, at the last count, been cited over 186 times and is still the only prospective, descriptive, community-based account of the condition to date. It found that nausea occurs just as commonly after midday than before, and whilst vomiting occurs more usually in the mornings it can happen at any time during waking hours. The more accurate description of the condition would be ‘episodic daytime pregnancy nausea and vomiting’ but that doesn’t have the same catchy quality as ‘morning sickness’, does it?
"One of the reasons I began my research was when a patient came to me saying: 'I have had such severe nausea and vomiting symptoms that I don’t want to have any more children, what causes it?' It can be so severe that women suffering from it have to terminate their pregnancy, such is the impact of the condition.
"In my research, pregnancy nausea and vomiting was positively related to weight of the placenta and I believe the condition is also related to the intense immunological suppression that takes place which enables an immunologically foreign foetus to develop without being rejected by its mother. The research has also shown an association between the symptoms and blood levels of prostaglandin E2 a cytokine involved in this immunological suppression.
"I am committed to continuing my research, which I hope will help inform and improve the treatment of morning sickness for thousands of women."
To hear Dr. Gadsby talking about morning sickness and the possible causes, tune into Radio 4’s Case Notes programme with Dr Mark Porter. It is due for broadcast on 1 March at 9pm and will be repeated on Wednesday 2 March at 4.30pm

Researchers at Warwick Medical School are looking for new mums to take part in the Mums 4 Mums study about postnatal depression.
The study is based on a sucessful programme developed and evaluated in Canada and will explore whether using support staff who have personally experienced postnatal depression and recovered, is more helpful to new mums.
Sukhi Sembi from WMS explained "If you live in the Coventry and Warwickshire area, have a baby under the agae of two years old and are feeling low, overwhelmed or suspect you have symptoms of postnatal depression, please contact us."

We want to offer a warm welcome to visitors from Sweden’s Karolinska Institutet who are visiting Warwick Medical School today.
Karolinska are currently reviewing their MB ChB undergraduate curriculum. WMS’ reputation for providing internationally respected medical teaching on its MB ChB course has resulted in an opportunity to share how we manage our programme, including insight into how we manage clinical placements, education supervision, assessment and selection, and curriculum design.
Visiting guests include Professor Sari Ponzer, Dean, Higher Education, and Anna-Lena Paulsson, Head of the International Relations Unit. Their itinerary includes a visit to Warwick Hospital to see students at work in their clinical placements.

Heart-shaped chocolates, cushions and all manner of lovey-dovey gifts are adorning the shelves in readiness for Valentine’s Day. But for some would-be doctors at Warwick Medical School, they are about to get their hands on the real thing – a human heart.
The students get to see a real human heart which has been ‘plastinated’ or expertly treated to preserve every tiny vein and valve to become a valuable teaching resource as part of their clinical anatomy training.
Peter Abrahams, Professor of Clinical Anatomy, explained: “This plastinated heart is the next best thing to examining a living organ. Students can handle and study it to understand how the valves and muscles work and is a tremendous aid for their learning.”
The heart is one of a number of specimens the Medical School has. Others include a complete arm from shoulder to hand and a thorax including lungs and rib cage.
“The lecture room is always full when it’s time to study the plastinated specimens,” he added.
