Hypertension is a state of adaptation of the body to a generalized drought, when there is not enough water to fill all the blood vessels that diffuse water into vital cells.
As part of the mechanism of reverse osmosis, when water from the blood serum is filtered and injected into important cells through minute holes in their membranes, extra pressure is needed for the "injection process." Just as we inject I.V. "water" in hospitals, so the body injects water into tens of trillions of cells all at the same time.
Water and some salt intake will bring blood pressure back to normal.
Hypertension or high blood pressure is more of a chronic health problem associated with the body being out of balance. It's heavily influenced by lifestyle factors, including diet, activity level, and stress level. A healthy, well-balanced diet, regular aerobic exercise, and stress reduction are more than sufficient to lower blood pressure to normal levels in most people.
Hypertension causes the left ventricular wall to thicken. This is followed by a dilatation of the left ventricle and a reduction in the amount of blood pumped from the heart.
An increase in blood pressure is a response to stress. The nervous system engages in the 'fight or flight' response when a person is under stress, anything from a bear attack to your boss yelling at you. Blood pressure is increased in two ways: First, blood vessels constrict as a response to an increase in epinephrine, and as a way to increase blood flow to the muscles. Second, the heart pumps faster, in order to increase blood flow to the brain and muscles, thus increasing alertness and muscular readiness. Hypertension is sometimes brought on over time by several factors, such as sedentary lifestyle, poor diet, genetics, and living a high stress life (like many of us do!) Being under constant stress essentially 'trains' your body to remain at this state of hypertension even when there is no acute stress. Yoga, exercise, improved diet, and sometimes bp meds can all help to control hypertension. Not treating hypertension can lead to several nasty outcomes: * stroke * heart attack * kidney failure If you or one of your loved ones has untreated hypertension, get them to the doctor.

DefinitionDrug-induced hypertension is high blood pressure caused by using a chemical substance, drug, or medication.See also: High blood pressureAlternative NamesHypertension - medication relatedCauses, incidence, and risk factorsBlood pressure is determined by the:Amount of blood the heart pumpsCondition of the heart valvesPumping power of the heartSize and condition of the arteriesThere are several types of high blood pressure.Essential hypertension has no cause that can be found.Secondary hypertension occurs because of another disorder.Drug-induced hypertension is a form of secondary hypertension caused by a response to medication.Drugs that can cause hypertension include:Alcohol, amphetamines, ecstasy (MDMA and derivatives), and cocaineCorticosteroidsCyclosporineErythropoietinEstrogens (including birth control pills) and other hormonesMany over-the-counter medications such as cough/cold and asthma medications -- particularly when the cough/cold medicine is taken with certain antidepressants like tranylcypromine or tricyclicsMigraine medicationsNasal decongestantsRebound hypertension occurs when blood pressure rises after you stop taking or lower the dose of a drug (typically a high blood pressure medication).Many other factors can also affect blood pressure, including:Condition of the kidneys, nervous system, or blood vesselsGeneticsFoods eaten, weight, and other body-related variablesLevels of various hormones in the bodyVolume of water in the bodySymptomsThe symptoms of drug-induced hypertension are the same as those of primary hypertension, and may include:AnxietyChest painConfusionExcessive perspirationHeadacheMuscletremorsNausea and vomitingPale skin or rednessTirednessVision changesNote: Hypertension usually has no symptoms.Signs and testsThe health care provider will ask you questions about your use of drugs known to affect blood pressure measurement.Repeated blood pressure measurements can confirm the diagnosis. Blood pressure that is consistently high is considered hypertension.Two factors determine blood pressure measurements. Systolic blood pressure is the "top" number. It measures the pressure in the blood vessels when the heart beats. Diastolic blood pressure is the "bottom" number. It is the pressure in blood vessels when the heart is at rest.Normal blood pressure is defined as a systolic (top) pressure of less than 120 mmHg, and a diastolic (bottom) pressure of less than 80 mmHg. A consistent rate of more than 140 mmHg systolic and more than 90 mmHg diastolic is considered high blood pressure.Systolic BP between 130 and 140 mmHg and/or diasolic BP between 80 and 90 mmHg are considered pre-hypertension.Blood tests may be done to determine the levels of medications that may be causing the high blood pressure.TreatmentThe goal of treatment is to reduce your blood pressure to below 140/90 (below 130/80 if you have diabetes or kidney disease). This will lower the risk of complications.If possible, stop taking the substance that caused your hypertension. Your health care provider may adjust your treatment if your current medications are causing hypertension and you cannot stop taking these drugs.Medications that may be used to lower blood pressure include:Aldosterone blockersAngiotensin-converting enzyme (ACE) inhibitorsAngiotensin receptor blockers (ARB)Beta blockersCalcium channel blockersDiureticsHydralazine, doxazosin, and prazosinHave your blood pressure checked regularly (as recommended by your health care provider) to monitor its response to treatment.Lifestyle changes may be recommended, including:Avoiding excess alcoholDietary changesExerciseWeight lossExpectations (prognosis)Drug-induced hypertension is usually controllable with treatment. Treatment may need to be changed periodically.ComplicationsComplications of untreated hypertension can include:Blood vessel damageCongestive heart failureHeart attackKidney damageLoss of visionOther heart damageStrokeCalling your health care providerIf you have high blood pressure, you will have regularly scheduled appointments with your doctor.In between appointments, call your health care provider right away if you have any of the following symptoms:Chest painConfusionExcessive tirednessNausea and vomitingSevere headacheShortness of breathSignificant sweatingVision changesPreventionBe careful when taking any medication. Ask your health care provider or pharmacist about the effects, and whether the medication might interact with other drugs you are taking (even over-the-counter medications).In people with hypertension, lowering salt (sodium) intake may be recommended. Products containing sodium (such as salt, MSG, and baking soda) may cause or worsen high blood pressure in some people.If your doctor suspects drug-induced hypertension, it is important to discuss all drug use -- including alcohol and other recreational drugs -- so that the condition can be properly diagnosed.ReferencesKaplan NM.

Yes. In the Cushing's reflex, which is due to traumatic head injury resulting in an increased intracranial pressure, the body exhibits what is called the CNS ischemic response. This response is due to activation of both the sympathetic nervous system (which constricts veins and arterioles to increase both peripheral resistance and increase venous return to the heart) and the parasympathetic nervous system (which acts to slow the heart rate by overriding sympathetic stimulation on the heart). This results in a concurrent bradycardia and hypertension

Corticosteroids is a class of chemicals that are produced in the adrenal cortex of vertebrates. These are used as medication for stress response, immune response, and regulation of inflammation.
That depends upon prognosis of disease and patient's response.
Depending on the medication, it can increase or reduce the effects (or have no interaction at all). Follow the instructions that came with the medication. Generally speaking it is unwise to use alcohol when taking any medication. For one thing, it can hinder the immune response.

The government broke them up trusts, and monopolies in response to pressure from the public under Teddy Roosevelt in a series of laws.
The latest evidence suggests that a blood pressure below 120/80 is "normal". Obviously, blood pressures that are much lower than that can be problematic, too. Blood pressures between 120/80 and 140/90 are classified as "pre-hypertension". Pressures above that represent true hypertension or "high blood pressure". A single high or low blood pressure does not necessarily mean that you have a blood pressure problem. Everyone's blood pressure rises and falls throughout the day and in response to certain stimuli. In order to minimize this effect, you should have three different measurements on three different days at three different times of day. Then you should average them to get a better idea of your true blood pressure.

Digitalis suggestion * Polyuria because your body is desperatly trying to remove it from the body via the kidneys and urine. * And I'll hazard a guess at the hypertension, perhaps due to the inhibition of the COX-2 pathway that results in the formation of prostaglandins that lower blood pressure. --------------------- Ywith suggestion (if associated hyponatraemia as well) Although, I originally asked the question, I think the polyuria is because of the osmotic effect of the salicylate displacing the sodium and causing polyuria. I am unsure as the to the hypertension and it may be a response to the lowered sodium detected in the macula densa of the kidneys, or as digitalis suggested because of one of the blood pressure effecting pathways being interfered with.

A conditioned response may become extinct is the reinforcer is not provided for some time. Consistent reinforcement is necessary to prolong a response.
Immunosuppressive drugs reduce the body's normal immune response. Most drugs augment the response, helping to fight off a pathogen the body would not be able to handle on its own.
Hi Jeanne-the amount of blood pressure medications and the specific combination prescribed is based upon multiple factors. These include coexisting medical problems, other medications and potential interactions, severity of the high blood pressure, response to blood pressure medications, and side effects. Sometimes, several medications may be necessary to control high blood pressure-this might be because one medication didn't work well enough or perhaps due to a side effect or difficulty tolerating the medication. In your case, you are on three medications for blood pressure (labetalol, doxazoxin, amlodipine) and a diuretic (spironolactone). Diuretics are sometimes used for blood pressure, and the blood pressure medications you are taking are of three separate classes, which is appropriate, but I can't say much more about the specifics. Your doctor has chosen your specific combination of medications taking into consideration all the factors I mentioned above. The other medicines (Zettia, lexapro, and vitamin D), do not treat high blood pressure. Your doctor can explain his or her reasoning for the prescribed blood pressure regimen.
