Breastmilk has been the primary source of sustenance for infants for decades. Breastmilk, which is produced by the mother’s body, is a complex fluid that serves a nutritional and regulatory role comparable to the placenta during pregnancy. In addition to just providing nourishment to the newborn, it shields the child from illness along with regulating specific facets of the infant’s behaviour and physiology. The survival of the human species largely depends on the success of the lactation.
A mother’s diet and nutrition, however, can directly or indirectly affect the quality of the breastmilk and, subsequently, the baby’s nourishment levels and the developmental process. Among various factors, alcohol consumption by breastfeeding mothers can be a huge factor in shaping an infant’s health and development. This article highlights the effects of alcohol on breastmilk.
How does alcohol affect breastmilk production?
Those who frequently drink alcohol typically have lesser milk production than those who don’t. Regular alcohol intake can adversely affect both the let-down reflex – a hormonal response that enables your body to expel milk so that you can breastfeed – and the overall breast milk supply.
Prolactin and oxytocin, two pituitary hormones, regulate breastfeeding – Breast milk production is stimulated by prolactin while the smooth muscle cells surrounding the mammary tissue that facilitates milk ejection contract in response to oxytocin.
The reduction in the breast milk supply of mothers taking alcohol can be explained by the ability of the alcohol to inhibit oxytocin, thereby reducing the milk ejection reflex. Some studies show that alcohol intake leads to a dose-dependent decrease in oxytocin levels, resulting in delayed milk ejection after breast stimulation. Furthermore, immediately after consuming alcohol, prolactin levels may rise, but overall milk output may reduce.
Which factors affect how long alcohol stays in mother’s milk?
Although there isn’t much evidence to support that breastfeeding mothers’ alcohol use modifies the composition of their breastmilk, it has been shown that alcohol use can impact the amount and quality of breastmilk produced as well as the health of the mother and child.
Alcohol levels in breast milk peak thirty to sixty minutes after drinking and are somewhat greater than those in the mother’s blood. Generally speaking, alcohol can be detected in mother’s milk for two to three hours after consumption.
The more alcohol a mother drinks, the longer it stays in her breast milk. For instance:
- One drink may last for two to three hours in the mother’s milk
- 2 drinks can be detected for four to five hours
- 3 drinks usually last for approximately 6 to 8 hours
While quantity consumed is the key determinant, the following variables may also impact how long alcohol stays in breast milk:
- How quickly alcohol is ingested.
- If food is consumed along with the alcohol.
- The weight of the mother.
- How quickly a mother’s body breaks down alcohol
What happens to the babies exposed to alcohol through breastmilk?
It is said that alcohol use during pregnancy has been linked to changes in the brain and behaviour of the developing foetus. However, alcohol consumption while breastfeeding may have the following effects on the baby:
- Children may take about 20% less milk in the first four hours following the mother’s alcohol consumption, reducing their overall nutritional intake, ultimately adversely affecting their overall development.
- Alcohol may alter the taste and smell of the breastmilk; as a result, the baby might even start disliking it.
- Drinking alcohol continuously while breastfeeding can also have an impact on a child’s sleeping patterns. This might interfere with their sleep-wake cycle, making it difficult for them to regulate their sleep.
- Furthermore, regular alcohol consumption during breastfeeding may have an impact on the cognitive and motor development of the infant.
Can alcohol interfere with a baby’s ability to feed or latch properly?
Regular feedings are essential for preserving an infant’s blood glucose and hydration levels. An infant’s capacity to feed can be impacted by alcohol and is one of the major effects of alcohol.
Alcohol consumption may also have an impact on your baby’s feeding performance and latching behaviour, potentially leading to delayed or weaker latch.
How can breastfeeding mothers avoid alcohol?
While it’s best to avoid alcohol altogether while nursing, as there is no safe level of alcohol has been established with breastfeeding. Moreover, alcohol consumption can affect a mother’s ability to make safe decisions for her baby. Hence, the best way to take proper care of your newborn is to completely avoid consuming alcohol. It can be done by:
- Consuming more of water and juices (adopting healthy habits)
- Asking somebody to stop you from drinking or keep reminding you
- Keep yourself full by eating good food
- Spend more time doing activities that interests you
Conclusion:
Overindulgence in alcohol might disrupt the milk ejection reflex, often known as letdown. It may eventually result in shorter breastfeeding durations because of reduced milk production. Drinking too much alcohol while nursing may also have an impact on the newborn’s growth, development, and sleep habits. For nursing mothers, abstaining from alcohol is the safest course of action.
