dangerous moments of high blood pressure

Core clew: patients with high blood pressure because long-term blood pressure is bigger, the blood vessels in the spasticity, so that blood vessel elasticity decreased, and the brittleness increases, if at this time due to some reason contributing to increased blood pressure suddenly, is easy to cerebral hemorrhage, cerebral vascular rupture and causing this for patients with high blood pressure, is undoubtedly the most fatal blow. Therefore, patients with hypertension should try to avoid a sudden rise in blood pressure, especially under the following circumstances, should be more cautious. Due to the long-term pressure on blood vessels, blood vessels are in a spasm state in patients with hypertension, resulting in decreased vascular elasticity and increased brittleness. If blood pressure rises suddenly due to some reason at this time, it is easy to cause cerebral vascular rupture and cerebral hemorrhage, which is undoubtedly the most fatal blow for patients with hypertension.

Low fiber diet leads to hypertension

 Recently, a study by Monash University scientists confirmed for the first time that a low fiber diet may lead to high blood pressure. If left untreated, high blood pressure can lead to stroke, myocardial infarction, stiffness of the heart's arteries and muscles, and kidney stiffness, thereby reducing its function. Hypertension is also the most common risk factor for cardiovascular disease.

In the study, published in the journal Circulation, the authors tested the difference between a high and low resistant starch diet using a mouse model. Resistant starch is a kind of fiber food, which can resist gastrointestinal digestion until it reaches the large intestine and is absorbed by probiotics.

The results showed that mice fed a low fiber diet were more likely to develop hypertension. After that, the researchers through the sterile mice fecal transplantation experiment showed that the low fiber diet caused by intestinal microbial ecological environment changes is the direct cause of hypertension.

"Hypertension remains a major risk factor for cardiovascular death," said lead author Dr. Francine marques, director of the National Heart Foundation at Monash University's School of biological sciences. A fiber deficient diet is associated with the prevalence of hypertension, but this study reveals the role of intestinal flora in it

Professor David Kaye, director of Cardiology at Alfred Hospital and head of heart failure at Baker college, CO led the study. Professor Kaye said that although it is well known that a high fiber diet can prevent the development of heart disease, the mechanism of this effect remains uncertain.

Microbial fermentation of resistant starch in the gut can release a series of metabolites, among which small molecules called short chain fatty acids (SCFA) can reduce blood pressure. The team found that even if the mice were fed these SCFAs directly without resistant starch fiber in their diet, their blood pressure decreased and their cardiovascular health improved.
