Nausea is a fact of life - well during pregnancy anyway!
Although it is known as morning sickness, it can actually occur at any time of the day. The first trimester is the usual phase for morning sickness, however some unlucky women can experience it throughout the entire pregnancy. There are many theories as to why morning sickness occurs and the general consensus is that it is due to increased hormone levels, in particular oestrogen. There are other theories that it is a protective mechanism for the mother and foetus. Mothers who are more sensitive to odours and have nausea are more likely to vomit up toxins and harmful bacteria. There are many old wives tales and traditional remedies for morning sickness with the best known and most used being ginger. Given the heightened sensitivity to odours experienced by pregnant women, aromatherapy could be a bit hit and miss as a therapy. However, a new study has been published that investigated the effects of lemon inhalation aromatherapy on nausea and vomiting in pregnant women. 100 women were included in the study and the levels of nausea, vomiting and retch intensity were investigated 24 hours before the women were given treatment and then the same measures were taken during the four days of treatment. Results showed that nausea and vomiting intensity on the second, third and fourth days of treatment were much lower in the treated group than the group with no treatment. Conclusion is that lemon scent is effective in reducing nausea and vomiting in pregnant women.
