MADICATION



Blood pressure (BP) is the pressure exerted bycirculating blood upon the walls of bloodvessels.

Blood pressure may be expressed as:

Blood Pressure = Cardiac Output x Peripheral

Vascular Resistance (PVR)Where Cardiac output is-

Cardiac Output = Stroke Volume × Heart rate



Blood pressure is measure by the reading ofSystolic blood pressure and/or Diastolic bloodpressure.

Category Systolic BP (mm Hg) Diastolic BP (mm Hg)

Hypotension <90 <60

Normal 90-120 60-80

Pre-hypertension 120-139 80-89

Stage I hypertension 140-159 90-99

Stage II hypertension ≥160 ≥100



Hypotension can be defined as either

A sustained systolic blood pressure of less than90 millimeters of mercury (mm Hg) or

A sustained diastolic blood pressure of lessthan 60 millimeters of mercury (mm Hg)

Hypertension is defined as either

A sustained systolic blood pressure of greaterthan 140 millimeters of mercury (mm Hg) or

A sustained diastolic blood pressure of greaterthan 90 millimeters of mercury (mm Hg)



Imbalance of blood pressure mainly depend onthe two parameters:

1. Peripheral vascular resistance

2. Cardiac output

Without these, heart rate and stroke volumewhich are related to cardiac output, blood

volume, capacitance of the venous system arealso related to the blood pressure.



1. Hypertension may occur secondary to otherdisease processes

2. Essential hypertension (90%), a disorder of

unknown origin affecting the blood pressureregulating mechanism

3. Family history of hypertension increases thechance of develop hypertensive disease.

4. Blacks are four fold more susceptible tohypertension than Whites.

5. Age and obesity



6. It occurs more often among middle-agedmales than among middle-aged females.

7. Stressful lifestyle

8. Diet such as high dietary intake of sodium, fatetc.

9. Smoking and tobacco products.



Blood pressure∝ Cardiac output and peripheralvascular resistance

These two are controlled mainly by two

overlapping control mechanisms:

1. The baroreflexes, which are mediated by thesympathetic nervous system, and

2. The renin-angiotensin-aldosterone system.

Decrease in bloodpressure

Decrease PVR Vasodilatation



Baroreceptors in the kidney respond to reducedarterial pressure and to sympatheticstimulation of β- adrenoceptors by releasing

the enzyme renin.

By this process kidney provides a long termcontrol of blood pressure by altering the bloodvolume.



Blood pressure problem is considered to be veryserious health problem in present day worldthat can cause heart disease and increase therisk of stroke.

This problem is termed as the silent killer.The unfortunate reality is that more than half of

the people taking multiple drugs for thisproblem, cannot manage their condition to anormal level. The good news is that over 85%of those who have this problem can normalizetheir blood pressure naturally through lifestyle

modifications.



1. Intake of Na+

Salt: Low sodium intake and greatersodium loss or high sodium intake can affect theblood pressure.

Decrease Na+ concentration

Decrease water retention

Decrease blood volume

Decrease cardiac output

Decrease blood pressure



2. Anxiety or stressful lifestyle: Anxiety ortension stimulate Sympathetic nervous system.

Anxiety or tensionfree life

No increase PVR



3. Diet: Intake less amount fat normalize bloodpressure.

Decreasefat intake

4. Avoid smoking: Smoking even secondarysmoking should be avoided or stopped.

5. Water of coconut: Green coconut water is a veryeffective natural medication for normalize bloodpressure, but contraindicated to the hypotensionpatients.

Increase K+ concentration

Decrease Na+ & waterretention

Decreaseblood volume

Decreasecardiac

Decreaseblood

6. Lose extra weight: By maintaining required weightaccording our height can normalize bloodpressure.

Extra weight

Produce extra pressure on bloodvessels

Produce vasoconstriction

Increased PVR

Increased blood pressure



7. Antioxidant: An antioxidant, help to stabilize cellactivity by reducing in blood pressure bymaintenance decrease vasoconstriction.

Examples: Vitamin C: Active compound is NO, act against

constricted blood vessels.

Grape Seed Extract: Active compound isProanthocyanidins, 20folds more potent than Vit.C

Olive Leaf Extract: Active compound isOleuropein, reduces LDL cholesterol.



8. Garlic: Garlic has achieved a legendary reputationas an antihypertensive medication. It's been usedin China for centuries for that purpose, and the

Japanese government officially recognizes garlic as

a blood-pressure depressor. American scientistsfirst tried garlic against high blood pressure in1921.

Garlic activate nitric oxide synthase and increase theNitric oxide level in the body and Nitric oxidework against constricted blood vesseles.

Contraindication: Garlic can reduce the ability of

blood clot.



• IncreaseNO level

• Decreasevasoconstriction

• DecreasePVR

• Decreasebloodpressure



9. Vitamin D: A lack of vitamin D can increase bloodpressure by increase synthesis of parathyroidhormone.

10. Apples: Apples contain potassium andphosphorus and are low in sodium. Appleswith honey have long been used for to reduce

blood pressure problems.11. Papayas: Half a papaya has more vitamin C

and potassium than an entire orange.

12. Cucumbers: Cucumbers are a good source ofpotassium, phosphorus and calcium as well asbeing a good diuretic.
