Association between Breastfeeding in reducing Hypertension risk

Women who breastfeed more children, and intended for the long period, are less likely to suffer from hypertension once they reach menopause. This is not true of obese women, however. Elevated blood pressure is the most prominent risk factor for disease and death. Proof from epidemiologic data has too revealed the advantageous effects of breastfeeding on the healthiness

of infants and their mothers. It has been reported that long-term breastfeeding is linked with reduced children's allergies, celiac disease, obesity, and diabetes mellitus. Though, the effects of breastfeeding on maternal health have been not much studied compared with the effects on the children.

Numerous studies reliably found that lacking breastfeeding or early discontinuation was related with increased risks of diabetes mellitus, dyslipidemia, metabolic disorder, coronary heart disease, and cardiovascular diseases. 

On the other hand few studies have recognized a clear relationship between breastfeeding and hypertension. The study population comprised 3,119 non-smoking postmenopausal women aged 50 years or older was taken under consideration. More children breastfed and the longer period of breastfeeding was associated with minor risk of hypertension in postmenopausal women, and level of obesity and insulin resistance directed the breastfeeding-hypertension correlation. In particular, the highest quintile of number of children breastfed (5 to 11) appeared a 51% lessen risk of hypertension compared by the lowest quintile (0 to 1). The highest quintile of the duration of breastfeeding (96 to 324 months) showed a 45% lower risk of hypertension. 

Even though a broad variety of chronic diseases are not linked with breastfeeding, a few common mechanisms have been anticipated to lie behind the relationships between breastfeeding and these diseases. First, maternal metabolism (e.g., fat accumulation and insulin resistance) may be "reorganize" by breastfeeding subsequent to pregnancy, which diminishes the risk of obesity-related diseases. Second, oxytocin discharge stimulated by breastfeeding may be related to the decreased risk of these diseases.
