An explanation of Pre-Eclampsia


Pre-Eclampsia is one of the most serious diseases that can complicate a pregnancy, putting at risk the lives of both the infant and the mother. The reasons why and how this condition occurs still remains essentially a mystery. Pre-Eclampsia is the development of high blood pressure along with protein in the urine (proteinuria), excessive fluid retention (oedema) and a rise in the uric acid level in the blood (hyperuricaemia). Once this condition develops it is necessary to deliver the infant, otherwise disastrous consequences can and will ensue. If we knew how this disease develops (its pathogenesis) then we may be able to intervene before the disease fully develops and improve the outcomes for both mother and infant. It has been estimated that 50,000 maternal deaths occur worldwide each year as a result of this disease!

I have been conducting research into Pre-Eclampsia since 1980. Listed below are sixteen research papers that have been published on the subject. The first of these, my ‘opus’, is a hypothesis on the pathogenesis of the disease. It was published in 2008.
