Pre-conceptual Nutrition

Obese women are less likely to get pregnant. A poor diet increases the risk of an unhealthy baby, birth defects and poor health in infancy and even adulthood for the child.

Nutrition Guidelines for 1st Trimester
Diet must be good. A poor diet at this stage will increase the risk of LBW (low birth weight), poor growth and baby is likely to have low weight at 1 year. May potentially lead to hypertension, diabetes and stroke later in life.

Poor nutrition in late pregnancy effects fetal growth.

Poor nutrition in early pregnancy effects development of CNS.
(Central nervous system)

Nutrition Guidelines for 2nd Trimester

Undernutrition may result in reduced birth weight but normal at 1 year old. May also lead to hypertension, type II diabetes and coronary heart disease.

Nutrition Guidelines for 3rd Trimester

Undernutrition may cause retardation in growth (brain growth is spared at the expense of body’s growth), normal growth weight but short in length and low weight at 1 year. Potentially the baby may suffer from hypertension, high cholesterol and stroke.

All women at child bearing age should have a balanced diet.
