Even when acclimatized, prolonged exposure to high altitude can interfere with pregnancy and cause intrauterine growth restriction or pre-eclampsia. [28] High altitude causes decreased blood flow to the placenta, even in acclimatized women, which interferes with fetal growth. [28]
The most serious symptoms of altitude sickness arise from edema (fluid accumulation in the tissues of the body). At very high altitude, humans can get either high-altitude pulmonary edema (HAPE), or high-altitude cerebral edema (HACE). The physiological cause of altitude-induced edema is not conclusively established.
Chronic mountain sickness (CMS) is a disease in which the proportion of blood volume that is occupied by red blood cells increases (polycythaemia) and there is an abnormally low level of oxygen in the blood . CMS typically develops after extended time living at high altitude (over 2,500 metres (8,200 ft)).
With high blood pressure, the force of blood flowing through your blood vessels is consistently too high. Around 75 million Americans have high blood pressure (or hypertension), and almost half of ...
“Although high blood pressure typically causes no symptoms and people may feel perfectly well, long-term high blood pressure has been conclusively shown to damage internal organs, particularly ...
High blood pressure, also called hypertension, is a vicious and smart adversary.It’s vicious because it greatly increases the odds of heart disease and stroke, some of the leading causes of ...
The study concluded that NAION could occur under high-altitude conditions, often in younger individuals with obstructive sleep apnea and "disc-at-risk". [22] Each apnea episode typically causes temporary increases in blood pressure and heart rate, leading to fluctuations that can result in irregular blood flow to the brain.
