When salt is ingested, it is dissolved in the blood as two separate ions – Na + and Cl −. The water potential in blood will decrease due to the increased solutes, and blood osmotic pressure will increase. While the kidney reacts to excrete excess sodium and chloride in the body, water retention causes blood pressure to increase. [10]
Reduced salt intake also results in a small but statistically significant reduction in blood pressure. [19] [26] Left ventricular hypertrophy (cardiac enlargement): "Evidence suggests that high salt intake causes left ventricular hypertrophy. This is a strong risk factor for cardiovascular disease, independently of blood pressure effects."
[18] [19] [20] High blood pressure affects 33% of the population globally. [9] About half of all people with high blood pressure do not know that they have it. [9] In 2019, high blood pressure was believed to have been a factor in 19% of all deaths (10.4 million globally). [9] Video summary
A drop in blood pressure. Poor blood circulation. Cardiovascular disease. Low blood sugar. Dehydration. Carbon monoxide poisoning. There are two types of vertigo — peripheral and central — and ...
Due to its sympathomimetic effects, pseudoephedrine is a vasoconstrictor and pressor agent (increases blood pressure), a positive chronotrope (increases heart rate), and a positive inotrope (increases force of heart contractions). [18] [1] [22] [19] [20] The influence of pseudoephedrine on blood pressure at clinical doses is controversial.
The Hopi Native Americans of Arizona use quartz crystals to assist in diagnosing illnesses. [14] Both Pliny the Elder and Galen claimed that certain crystals had medicinal properties. In Europe, the belief in the healing powers of crystals (and in particular crystal amulets) persisted into the Middle Ages.
Dizziness is a common medical complaint, affecting 20–30% of persons. [4] Dizziness is broken down into four main subtypes: vertigo (~25–50%), disequilibrium (less than ~15%), presyncope (less than ~15%), and nonspecific dizziness (~10%). [5] Vertigo is the sensation of spinning or having one's surroundings spin about them. Many people find ...
A low sodium diet has a useful effect to reduce blood pressure, both in people with hypertension and in people with normal blood pressure. [7] Taken together, a low salt diet (median of approximately 4.4 g/day – approx 1800 mg sodium) in hypertensive people resulted in a decrease in systolic blood pressure by 4.2 mmHg, and in diastolic blood pressure by 2.1 mmHg.
