Breastfeeding and Hypertension

Written by Crystal Karges, DTR, CLEC

Undoubtedly, the field of lactation continues to be an exciting subject of study, particularly as newfound evidence from developing research studies are confirming and fortifying the importance and benefits of breastfeeding. Knowledge of the latest research findings can be invaluable to the clinician who has the opportunity to encourage and educate the breastfeeding mother, particularly as they are able to assist in overcoming obstacles to breastfeeding that could make a difference in women’s health.

A recent study published in the American Journal of Epidemiology demonstrated that mothers who breastfed for a minimum of six months were less prone to developing hypertension over a 14 year period compared to those who bottle fed. These findings are contiguous with previous studies which have established that women who breastfeed have lower risks of diabetes, heart disease, and high cholesterol later in life.

In this latest study, researchers examined the relationship between breastfeeding and later risk of developing hypertension among approximately 56,000 American women who took part in this long-running study. All women participating in this research had at least one baby.

While findings included substantiation that an estimated 8,900 women from this study were ultimately diagnosed with high blood pressure over more than 20 years, data revealed that the probability women would develop hypertension were 22 percent higher in the incidence of not breastfeeding compared with women who exclusively breastfed for six months.

More specifically, this particular study concluded that never or abridged lactation was correlated with an increased risk of incident maternal hypertension, contrasted with the endorsed 6 months of exclusive or 12 months of total lactation per child. Researchers had also estimated that up to twelve percent of high blood pressure cases among women with children could be associated with “suboptimal” breastfeeding, including mothers who gave their babies formula or breastfed for less than three months. These findings are of utmost significance to the lactation consultant, who may make the difference in a mother’s long-term health by removing barriers that may prevent her from successfully breastfeeding.

Research findings such as these continue to give substantial support to the role of the lactation consultant in a mother and baby’s well being, particularly as the LC has the ability to empower a mother to create optimal health for herself.

    I feel like breast feeding is increasing my blood pressure. I have never had high blood pressure until now. I developed high blood pressure after my girl was born. I spend a long time in the hospital because of it. I have exclusively breast fed my baby up to 6 months and still breastfeeding at 9 + months. I feel the pressure increase when breast feeding, if I take it before then after breast feeding it is considerably higher. I reduce my breast feeding for two months and I was able to come off my medication but I am back to breast feeding and it is high again. I am sure there is a correlation but maybe it is not with all women. I have a 14 year old daughter and I had a different experience with her, breast feeding was relaxing but with my baby it is hurt especially after a long night.

      I’m having to stop breastfeeding my 8 month old due to high blood pressure problems and medication interactions. After tracking my readings day/night, I’ve noticed my blood pressure is always much higher after the time when my daughter would cluster feed at night. With my first child, I didn’t have this happen, so it’s very upsetting to have happen.

    I have had this hypertension before my girl was born. Close to the labor period, the tension subsided but now especially during lactation and breastfeeding I find it alarming as the tension went up abruptly.
