High Blood Pressure


Control Your Pressure
The average adult has about five liters of blood flowing through the body via an intricate network of blood vessels called arteries, veins and capillaries. Blood is essential to life for it delivers oxygen from our lungs to our body tissues, and carries harmful waste to the kidneys to be removed. Blood also transports hormones from our glands to various parts of our bodies, as well as vitamins and nutrients from our digestive tracts.
When our blood vessels become clogged due to a plaque buildup of cholesterol and fat, our hearts must work twice as hard to pump enough blood to our vital organs. This is what causes our blood pressure to surge.
As the pressure increases inside of our arteries, veins and capillaries, our hearts become even more overworked. Over time, our hearts grow larger in an effort to compensate for the extra workload and eventually they become weaker.
When you add obesity, smoking, or diabetes to the mix, the risk of heart attack, stroke or kidney disease for those with high blood pressure increases dramatically. This is why it is important to know what your blood pressure is.
Experts recommend that you maintain a blood pressure lower than 140/90 mm Hg at rest. The higher number represents the maximum pressure exerted when the heart contracts (systole). It reflects the stiffness of the large arteries near the heart, and the volume of blood pumped into them. The lower number represents the pressure exerted when the heart begins to relax between beats (diastole), just before the next contraction. It measures the amount of constriction of the body's smaller arteries or arterioles.

Three Health Tips :
Move MoreMake it a daily challenge to find ways to move your body. Climb stairs if given a choice between that and escalators or elevators. Walk your dog; chase your kids; toss balls with friends, mow the lawn. Anything that moves your limbs is not only a fitness tool, it's a stress buster. Think 'move' in small increments of time. It doesn't have to be an hour in the gym or a 45-minute aerobic dance class or tai chi or kickboxing. But that's great when you're up to it. Meanwhile, move more. Thought for the day: Cha, Cha, Cha…. Then do it!


Cut Fat Avoid the obvious such as fried foods, burgers and other fatty meats (i.e. pork, bacon, ham, salami, ribs and sausage). Dairy products such as cheese, cottage cheese, milk and cream should be eaten in low fat versions. Nuts and sandwich meats, mayonnaise, margarine, butter and sauces should be eaten in limited amounts. Most are available in lower fat versions such as substitute butter, fat free cheeses and mayonnaise. Thought for the day: Lean, mean, fat-burning machine…. Then be one!

Quit Smoking The jury is definitely in on this verdict. Ever since 1960 when the Surgeon General announced that smoking was harmful to your health, Americans have been reducing their use of tobacco products that kill. Just recently, we've seen a surge in smoking in adolescents and teens. Could it be the Hollywood influence? It seems the stars in every movie of late smoke cigarettes. Beware. Warn your children of the false romance or 'tough guy' stance of Hollywood smokers. Thought for the day: Give up just one cigarette…. the next one.
Practice Every Day

Know about Cholesterol....

Low-density lipoprotein, or LDL, is known as “bad” cholesterol.
High-density lipoprotein, or HDL, is known as “good” cholesterol.
These two types of lipids, along with triglycerides and Lp(a) cholesterol,
make up your total cholesterol count,
which can be determined through a blood test.

LDL (Bad) Cholesterol
When too much LDL (bad) cholesterol circulates in the blood,
it can slowly build up in the inner walls of the arteries that feed the heart and brain.Together with other substances, it can form plaque, a thick,
hard deposit that can narrow the arteries and make them less flexible.
This condition is known as atherosclerosis. If a clot forms and blocks a narrowed artery,heart attack or stroke can result.

HDL (good) Cholesterol
About one-fourth to one-third of blood cholesterol is carried by high-density
lipoprotein (HDL). HDL cholesterol is known as “good” cholesterol,
because high levels of HDL seem to protect against heart attack. Low levels of
HDL (less than 40 mg/dL) also increase the risk of heart disease. Medical experts think that HDL tends to carry cholesterol away from the arteries and back to the liver,where it's passed from the body. Some experts believe that that HDL removes excess cholesterol from arterial plaque, thus slowing its buildup.

Triglycerides
Triglyceride is a form of fat made in the body. Elevated triglycerides can be due to overweight/obesity, physical inactivity, cigarette smoking, excess alcohol
consumption and a diet very high in carbohydrates (60 percent of total calories or more).People with high triglycerides often have a high total cholesterol level, including a igh LDL (bad) level and a low HDL (good) level. Many people with heart disease and/or diabetes also have high triglyceride levels.

Lp(a) Cholesterol
Lp(a) is a genetic variation of LDL (bad) cholesterol. A high level of Lp(a) is a significant risk factor for the premature development of fatty deposits in arteries. Lp(a) isn’t fully understood, but it may interact with substances found in artery walls and contribute to the buildup of fatty deposits.
