What’s causing the weight gain?

Gaining weight during pregnancy is a natural and necessary aspect of the mother's journey. It helps the baby grow and develop and gets the mother's body ready for nursing and birthing. Pregnancy causes an overall rise in weight due to several factors:

  • Foetal Development: It doesn’t come as a surprise that the growth and development of the foetus account for a sizable amount of the weight gained throughout pregnancy. This includes the baby's weight, the placenta, the amniotic fluid, and the elevated blood volume.
  • Placenta: The placenta is a vital organ that develops during pregnancy and is vital to the growth and development of the foetus. It acts as a lifeline between the mother and the foetus by providing it with nutrients and oxygen.
  • Amniotic fluid: This fluid envelops and cushions the developing embryo inside the womb. As a pregnancy continues, the amount of amniotic fluid increases, leading to weight gain.

  • Uterus enlargement: One of the main causes of weight gain is the uterus's increasing size and weight. The uterus grows to make room for the growing foetus as the baby continues to get bigger. 
  • Maternal fat: To meet the energy needs of labour, lactation, and the postpartum period, the body naturally stores more fat throughout pregnancy.
  • Increase in blood volume: The mother and the unborn child have expecting demands. To fulfil those demands, the body undergoes a rise in blood volume during pregnancy. This rise adds to the total growth in weight.
  • Breast tissue enlargement: To prepare for nursing, the breasts go through changes. This results in an increase in size and the growth of tissue that produces milk, which adds to the overall healthy weight gain in pregnancy.
  • Fluid Retention: A slight retention of fluid in some pregnant women may cause a brief weight gain.

Is weight gain important during pregnancy?

Appropriate weight gain during pregnancy is vital for a healthy maternal journey. This is because weight added to the body from the baby, placenta, amniotic fluid, and increased blood volume, all contribute significantly to the infant's growth. Sufficient weight gain supports the construction of organs, bones, and tissues in the foetus by supplying vital nutrients. Maternal weight gain also acts as a buffer against the energy demands of childbirth, lactation, and the postpartum period. 

Reaching a healthy weight growth aids in the avoidance of complications like low birth weight, premature birth, and problems with development. Additionally, it aids in the physiological changes that the mother experiences during pregnancy, including the uterus' growth and the formation of breast tissue necessary for nursing.
