Why is hypertension dangerous?
Hypertension forces the guts to work tougher to pump blood. Over time, the overwhelmed coronary heart can slowly begin to falter and wrestle to pump blood out to the remainder of the physique, a situation known as coronary heart failure.
The power and friction of hypertension also can injure the delicate lining of the arteries, Dr. Liu mentioned. Tears within the artery wall enable LDL cholesterol — also called the “unhealthy” ldl cholesterol — to latch on and type clumps, or plaques, in these gaps. This will block blood circulation and, in some sufferers, trigger a coronary heart assault.
Blockages in arteries that carry blood to the mind can result in a stroke. Lengthy-term harm to blood vessels within the mind also can lead to a condition called vascular dementia, Dr. Liu mentioned.

Some research suggests that following a low-sodium weight loss program might scale back blood strain by two to eight mm Hg for some sufferers, and that adopting the DASH weight loss program — which emphasizes fruits, greens and low-fat dairy merchandise — might scale back blood strain by eight to 14 factors.
