There is a link between Bisphenol A and an increase in blood pressure.

By | November 23, 2021

Bisphenol A and High blood pressure (BP) has reach pandemic proportions in the world’s population. In the United States, one out of every three adults is hypertensive, and another one out of every three is pre-hypertensive. Bisphenol A, according to researchers studying the causes of high blood pressure, is a substantial contributor to this state of things.

(BPA) is a chemical that is utilise in the production of a variety of items, including water bottles, food containers, contact lenses, and even dental fillings. According to new research, BPA from plastic bottles leaches into the food products inside and elevates blood pressure within a few hours. The study findings also show that even a single exposure to canned beverages/food intake can have an influence on a person’s cardiovascular health.

BPA has been classify as a chemical of high concern and a significant endocrine disruptor by the European Chemicals Agency.

Urine output and blood pressure

Urine output and high blood pressure have a direct relationship: a hypertensive patient has higher urine output.
Several investigations employing urine BPA measurements have found a link between serum BPA and hypertension. This relationship remain largely steady regardless of age, gender, BMI, or diabetes status.

It has been shown that drinking from a can causes an increase in BPA levels in urine after 2 hours, however drinking from a glass bottle does not cause an increase in BPA levels in urine.

BPA and high blood pressure

According to research, there is a clear relationship between BPA content and blood pressure. Following BPA exposure, blood pressure rises by 5 points, which might be a substantial proportion for people who are already hypertensive.
Nonetheless, studies do not indicate the development of chronic hypertension as a result of repeat BPA exposure. More long-term investigations are need to clarify this point.

Consuming canned drinks

BPA is frequently employe in the production of plastic bottles as well as the inner coating of beverage cans. Experiments reveal that consuming two canned beverages (soft drinks or soups) raises systolic blood pressure by 4.5 mm Hg, but consuming the same two liquids from glass bottles has no effect.


BPA levels after canned soymilk: Because it contains no additives that might induce an increase in blood pressure, canned soymilk was employe in certain trials.
The urine of people who drank soymilk from cans had much higher BPA levels than those who drank from glass bottles, according to the results of the experiment.

People who had two servings of soymilk from cans had a 5mm Hg increase in systolic blood pressure, but those who consume two servings from a glass bottle had no change.

BPA’s effects on the cardiovascular system

Although the precise mechanism of action of BPA on the cardiovascular system is unknown, a variety of paths are plausible. Humans are most expose to BPA through the mouth.

BPA has been link to all hypertension criteria, however the link was weak for high systolic and diastolic blood pressure.

The BPA exposure alters the process of insulin secretion, resulting in weight gain and obesity. Which is a known risk factor for hypertension.

BPA has the ability to attach to thyroid hormone receptors. It affects the activities of free thyroid hormone by lowering its amount.

Estrogen plays a key role in endothelial modulation. Estrogen receptors have an important role in blood vessel healing and blood pressure regulation. BPA is a xenoestrogen that is thought to imitate the effects of oestrogen in the body. This interferes with both oestrogen levels in the body and oestrogen activity on its receptors. BPA has been proven to have a larger impact on blood pressure in postmenopausal women.

Long-term BPA exposure, even at low levels, can disrupt the biological functioning of the circulatory system. Leading to circulatory disorders such as arrhythmias. Cardiac remodelling, atherosclerosis, and hypertension.
Changes in the underlying molecular pathways, such as fast signalling of oestrogen receptors. Change of cardiac calcium channels by phosphorylation of proteins involve in calcium mobilisation. And oxidative stress, produce these problems.

BPA is a potential toxin to cardiac cells, causing reactive oxygen species through increase oxidative degradation of lipids. Decrease glutathione levels, and decrease activity of the enzyme catalase. Another impact of BPA is oxidative stress injury to primary endothelial cells.

Continue BPA exposure lowers the body’s nitric oxide (NO) level. Which can induce vasoconstriction and inadequate blood flow the beating heart BPA also inhibits the function of acetylcholinesterase in the body. Which can lead to decrease cardiac contractility and a slower pulse.
