Morning sickness describes the symptoms of nausea and vomiting during early pregnancy and can occur at any time of day. Causes of morning sickness may be related to increased levels of oestrogen that slows the emptying of the stomach and heightens sense of smell. Evolution may cause the symptoms as a way to prevent food poisoning as mothers tend to be put off foods that risk contamination (poultry, meat, eggs) preferring to eat low risk dried foods instead.
The causes of morning sickness, also known as nausea and vomiting in
pregnancy (NVP), remain unclear but experts have a number of theories
which may explain the condition.
The common theories include:
Hormonal changes – during the first trimester (three months) of pregnancy, the hormone called 'oestrogen' rises which may trigger nausea and vomiting. The hormone heightens the sense of smell which explains why many women find that certain smells will trigger symptoms.
Adaptation – many scientists believe that evolutionary adaptation (or the change an organism makes to adapt to its environment) is the cause of morning sickness as the woman tries to protect the baby from food poisoning.
A common complaint during early pregnancy is that certain foods are off-putting, particularly those foods that can be easily contaminated such as meat, poultry and dairy products. The preference is for foods which have a low contamination risk such as dry foods (bread, cereals etc.).
