Brief view about Hypertension

Sep 23rd 2014 at 12:44 AM

HYPERTENSION Heart pumps out blood with some pressure so that it can easily reach extremes. During heart pump, blood has pressure that exerts over the wall of the arteries called blood pressure. High blood pressure (hypertension) means that your blood is pumping at a higher pressure than normal through your arteries

Hypertension now disproportionately impacts low and middle income countries.Two thirds of those with hypertension are in economically developing countries.Heart disease and stroke occur in younger people in economically developing countries. Increased blood pressure was the cause of an estimated 9.4 million deaths and 162 million years of life lost in 2010 and the cause of (2-8).50% of heart disease, stroke and heart failure.13% of deaths overall and over 40% of deaths in people with diabetes.Hypertension is a leading risk for fetal and maternal death in pregnancy, dementia, and renal failure

Approximately 4 in 10 adults over age 25 have hypertension and in many countries another 1 in 5 have prehypertension.An estimated 9/10 adults living

to 80 years of age will develop hypertension.One half of blood pressure related disease occurs in people with higher levels of blood pressure even within the normal range.

TYPES: There are two types of hypertension based on their causes, they are:  Primary or essential hypertension – in almost 90 to 95 percent adult with high blood pressure, there is no identifiable hypertension cause, which develops gradually over several years. o Causes  Stressful life  Blood volume increase or forceful heart beating  Salt sensitive individuals  Abnormality in the arteries  Secondary hypertension – in almost 5 to 10 percent individual with high blood pressure, there is an identifiable underlying condition causing hypertension, which develops suddenly. The various health conditions that cause hypertension are kidney problems, adrenal gland tumors, and congenital blood vessel defects. o Causes:  Sleep apnea  Thyroid disorder  Chronic renal disease  Renal artery stenosis


You get hypertension if  You are obese  You are often stressed or anxious

 You drink too much alcohol (more than 1 drink per day for women and more than 2 drinks per day for men)  You eat too much salt  You have a family history of high blood pressure  You have diabetes  You smoke SYMPTOMS:  Nosebleed  Face or eye turns red  Vision problem  Increased heart rate  weakness  sleep (Insomnia)Sore back and/or kneeChest oppression,  palpitations  Shortness of breath  Irritated, and getting anger easily MEASURING HYPERTENSION: Its measured in millimeter per mercury. It is measured with two parameters. They are categorized as:  systolic pressure – the pressure of the blood when your heart beats to pump blood out. The normal systolic pressure is usually between 110 and 130mmHg.  diastolic pressure – the pressure of the blood when your heart rests in between beats, which reflects how strongly your arteries are resisting blood flow. The normal diastolic pressure is usually between 70 and 80mmHg.

RISK FACTORS: This hypertension can result in: Kidney disease Stroke Heart attack Heart failure Recently, new guidelines released by the U.S. revised the normal range of blood pressure to 150/90 for people above 60 years of age. Read more about the guideline. 150/90 is the new ‘normal BP’ for people over 60 Here is the range of readings and the diagnosis based on them. Category Systolic BP Diastolic BP Normal < 120 And < 80 Pre-hypertension 120-139 Or 80-89 Hypertension, stage I 140-159 Or 90-99 Hypertension, stage II >160 Or > 100 TREATMENT:  Eat a heart healthy diet, including potassium and fiber.

 Drink plenty of water.  Exercise regularly for at least 30 minutes of aerobic exercise a day.  If you smoke, quit.  Limit the amount of sodium (salt) you eat -- aim for less than 1,500 mg per day.  Reduce stress. Try to avoid things that cause you stress, and try meditation or yoga to de-stress.  Stay at a healthy body weight.  Lifestyle modifications:Lose weight  Avoid alcohol  Eat a low-sodium, low-fat diet  The researchers started off examining what the impact of consuming nitrates might be on laboratory rats, and then confirmed their findings with 15 volunteer humans, all with hypertension. The following foods are high in nitrates:  Beetroot  Fennel  Cabbage  Lettuce  Radishes  Carrots.

Stay healthy :)
