Low birthweight, thinness and short body length at birth are now known to b
e associated with increased rates of cardiovascular disease and non-insulin
dependent diabetes in adult life. The fetal origins hypothesis proposes th
at these diseases originate through adaptations which the fetus makes when
it is undernourished. These adaptations may be cardiovascular, metabolic or
endocrine. They permanently change the structure and function of the body.
Prevention of the diseases may depend on prevention of imbalances in fetal
growth or imbalances between prenatal and postnatal growth, or imbalances
in nutrient supply to the fetus.
