Negative Effects of Having Liquorice While Pregnant

  • With high consumption of liquorice root, there is a high-risk chance of miscarriage or preterm delivery, which means a shorter gestation period. Premature birth in itself has drawbacks for the baby.
  • Consuming liquorice root during your pregnancy can lead to the impairing of the placenta. The compound found in liquorice, Glycyrrhizin, could increase the chances of your glucocorticoids or stress hormones to reach the baby in the uterus. This leads to an adverse effect on the foetus’s brain development, lowering the intelligence levels, and increasing the behavioural problems in the child as they grow up.
  • Chances of your child’s low cognitive skill development can also be a side effect of high liquorice root consumption. It is likely that your child may be prone to develop conditions such as attention deficit hyperactivity disorder or ADHD.
  • Liquorice root has an oestrogen-like effect, which could possibly cause severe foetal development complications if consumed in high quantities during your pregnancy. If a male foetus gets exposed to these high levels of oestrogen, the chances of him developing testicular abnormalities are high. This will eventually lead to infertility later in life. Meanwhile, if a female foetus is exposed to too much oestrogen during the growing period, she may develop reproductive tract issues.
  • The consumption of liquorice root while pregnant can also be associated with early puberty.
  • The root comprises a compound that increases cortisol levels, also known as the stress hormone leading to issues in the growth and development of the nervous system of the baby to be born.
  • Babies born to mothers who ate large amounts of glycyrrhizin-containing liquorice products during pregnancy were more likely to have brain impairments later in life.
  • It can cause hypertension, arrhythmia, and potentially cardiac arrest in certain cases.
  • Consuming the root can cause hormonal imbalance.
  • It may interfere with certain medications, like blood thinners.
  • Regular ingestion of liquorice is associated with hypertension, sodium and water retention, and hypokalemia (below normal levels of potassium in the blood).
  • Excessive liquorice consumption can cause metabolic alkalosis, low renin activity, and hypoaldosteronism.
