Blood Pressure Factors - What Affect Blood Pressure Readings

Posted by Healthfitline On Saturday, October 20, 2012
Today we are going to focus on possible factors that can affect the blood pressure readings. This topic is especially important for individuals who do not have a history of unstable blood pressure or individuals who have done everything possible to maintain a normal blood pressure, yet the BP readings still remains unstable.

In most cases, people diagnosed with blood pressure problems do suffer from other medical conditions and it is only in a few instances where other factors may be responsible for changes in blood pressure readings.

What can affect blood pressure? Here is a list of possible factors that can cause changes in blood pressure readings.

What Can Increase Blood Pressure
Age - As we age, the arteries becomes less elastic which can lead to slightly high blood pressure reading than usual.
  • Exercises
  • Stress - Responsible for stimulating the sympathetic nervous system. Sympathetic nervous system control the functions of vital signs like respiratory, BP and heart rate.
  • Medications - Medications like atropine sulfate and epinephrine can lead to increased blood pressure.
  • Time differences - Blood pressure is usually high in the late afternoon and early in the evening.
What Can Lower Blood Pressure
  • Medications like beta blockers and ACE inhibitors (antihypertensive medications).
  • Time variation - Blood pressure is usually lowest early in the morning.
Causes of False High Blood Pressure Readings
  • Bladder cuff too narrow.
  • Arm below the heart level.
  • Arm is un supported (the arm should be supported and placed at the same level with the heart).
  • Not having enough rest before taking the blood pressure.
  • Bladder cuff wrapped too loosely or it is not even.
  • If blood pressure is taken immediately after meal or when a person is smoking or under pain (should be taken 30 minutes after a meal).
  • Repeating of blood pressure taking too quickly (false high systolic or false low diastolic readings).
  • When the cuff is deflated too quickly (should be deflated at 2mm per sec). This leads to false low systolic or false high diastolic.
Causes of False Low BP Readings
  • Blood pressure cuff too wide
  • Arm above the level of the heart.
  • Unable to identify the auscultatory gap (the first clear sound heard over the stethoscope is the systolic and the last clear sound is the diastolic reading).
The above are just other possible factors that can affect the blood pressure readings but it does not mean that all blood pressure changes should be associated with these factors. In most cases, changes in blood pressure is usually due to other underlying medical conditions. Consult your physician for further evaluation.

Hypertension

Posted by Healthfitline On Tuesday, October 2, 2012
Hypertension is defined as an elevation of blood pressue of at least 140/90mmHg for atleast 3 times, consecutively. It is considered a major risk factor for developing cardiovascular, stroke and kidney failure.

Type of Hypertension
There are two types of hypertension;
  • Primary Hypertension also known as essential hypertension
  • Secondary Hypertension (due to other illness)
 
Risk factors associated with Primary Hypertension
  • Stress
  • Smoking
  • Excessive alcohol consumption
  • Intake of excessive salt or caffeine
  • Race (some races are more prone to developing hypertension than others)
  • Obese
  • Hereditary
  • Sedentery lifestyle
  • Not known cause
 
Risk Factors for Developing Secondary Hypertension
  • Acute glumerulonephritis (kidney infections)
  • Pregnancy (pregnancy induced hypertension)
  • Cushing syndrome
  • Kidney failure
  • Diabetes
  • Kidney tumor
 
Hypertension Symptoms
Initially, there are no other signs and symptoms presents apart from the increased blood pressure. Other signs and symptoms may appear later on such as; headache, nose bleeding, visual changes, dizziness, depending on the location of the blood vessels that is affected.
 
For example, in renal failure, patients can experience edema, protein in the urine,  increased BUN and Creatinine. If Cardiovascular system is affected, patient may experience chest pain,  left ventricular hypertrophy (thickening of the left side of the heart) or even heart attack.
 
Management of Hypertension 
  • DASH Diet (diet approach to stop hypertension).
  • Exercises
  • If the patient has been smoking, he or she is advised to stop.
  • The patient is advised to stop alcohol consumption.
  • Encouraged to live active lifestyle
  • Restriction of salt in the diet
  • Relaxation techniques to minimize stress.
  • Anti-hypertensive medications
  • If the patient has been taking other medications that may be increasing the blood pressure, the prescription is reviewed and changed or eliminated when necessary.
