==Overview==
==Overview==
Hypertension is usually found incidentally  by healthcare professionals during a routine checkup. The only test for hypertension is a blood pressure measurement.
Thorough history-taking is crucial for the diagnosis and assessment of hypertension. Not only should history-taking be targeted to identify symptoms consistent with high blood pressure, but more importantly it should address risk factors and target organ damage. History-taking alone may be sufficient to diagnose some causes of [[secondary hypertension]], such as drug-induced hypertension, and may allow a more targeted evaluation of the cause and treatment of the hypertension.


==History and Symptoms==
==Symptoms of Hypertension==
Hypertension in isolation usually produces no symptoms although some people may report either:
Most patients with hypertension are asymptomatic at the time of diagnosis. Common symptoms are listed below:  
*[[Blurred vision]]
*[[Headache]]
*[[Dizziness]]
*[[Blurry vision]]
*[[Facial flushing]]
*[[Dyspnea]]
*[[Epistaxis]]
*[[Tinnitus]]
*[[Fatigue]]
*[[Fatigue]]
*[[Headaches]]
*[[Drowsiness]]
*[[Tinnitus]]
 
==Symptoms Suggestive of Secondary Hypertension==
Other symptoms that might suggest secondary etiologies of hypertension include:
*[[Sleep apnea]] is suggested by [[obesity]], [[snoring]] and [[apnea]]
*[[Hyperaldosteronism]] is suggested by [[fatigue]], [[headache]], intermittent [[paralysis]], [[muscle weakness]], and [[numbness]]
*[[Pheochromocytoma]] is suggested by the triad of a [[headache]], [[sweating]], and [[palpitations]] in a young person
*[[Cushing's syndrome]] is suggested by a rapid [[obesity|weight gain]], particularly of the trunk and face with sparing of the limbs ([[central obesity]]), a round face often referred to as a "[[moon face]]", excess [[sweating]], [[insomnia]], reduced [[libido]], [[impotence]], [[amenorrhoea]], [[infertility]] and psychological disturbances, ranging from [[Euphoria (emotion)|euphoria]] to [[psychosis]]. [[clinical depression|Depression]] and [[anxiety]].<ref>{{cite book |title=The American Psychiatric Publishing Textbook of Neuropsychiatry and Behavioral Neurosciences |last=Yudofsky |first=Stuart C. |coauthors=Robert E.

*An extensive list of drugs can be associated with hypertension. The most common agents include immunosuppressive agents, non-steroidal anti-inflammatory drugs, [[oral contraceptive pills]], some weight loss agents, stimulants, monoamine oxidase inhibitors, triptans, ergotamines, and sympathomimetics.<ref name="pmid12537168">{{cite journal| author=Onusko E| title=Diagnosing secondary hypertension. | journal=Am Fam Physician | year= 2003 | volume= 67 | issue= 1 | pages= 67-74 | pmid=12537168 | doi= | pmc= | url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=12537168  }} </ref> A more extensive list of drugs includes [[almotriptan]], [[dihydroergotamine]], [[ergotamine]], [[frovatriptan]], [[isometheptene]], [[rizatriptan]], [[sumatriptan]], [[zolmitriptan]], [[amitriptyline]], [[cyclosporine]], [[desipramine]], [[doxepin]], [[ephedrine]], [[glucocorticoid resistance ]], [[imipramine]], [[monoamine oxidase inhibitor]]s, [[nasal decongestants]], [[nortriptyline]], [[NSAIDs]], [[combined oral contraceptive pill]], [[phencyclidine]], [[phenylpropanolamine]], [[protriptyline]], [[pseudoephedrine]], [[sedative dependence]], [[serotonin toxicity]], [[steroid abuse]], and [[cocaine]].

*Age
*Ethnicity
*[[Tobacco]]
*Medications
*Family history
*[[Alcohol]]
*[[Dyslipidemia]]
*[[Diabetes mellitus]]
*Known cardiovascular diseases
*Known kidney diseases
*Diet
*[[Obesity]]
*Sedentary lifestyle


[[Malignant hypertension]] (or accelerated hypertension) is distinct as a late phase in the condition, and may present with [[headaches]], [[blurred vision]] and end-organ damage. Large [[lunula]]e (more than 25% of the thumb nail) are also a sign of high blood pressure.
==Symptoms of Target Organ Damage==
===Eyes===
*[[Retinopathy]]


Hypertension is often confused with mental tension, stress and [[anxiety]]. While chronic anxiety is associated with poor outcomes in people with hypertension, it alone does not cause it. Accelerated hypertension is associated with [[somnolence]], [[confusion]], visual disturbances, and [[nausea]] and [[vomiting]] (hypertensive encephalopathy).
===Heart===
*[[Angina]]
*Prior [[MI]]
*Prior coronary revascularizations
*[[Aneurysm]]s
*Symptoms of [[heart failure]]
*Symptoms of [[peripheral vascular disease]] ([[PVD]])


=== Hypertensive Urgencies and Emergencies ===
===Kidneys===
Hypertension is rarely severe enough to cause symptoms. These typically only surface with a [[systolic blood pressure]] over 240 mmHg and/or a [[diastolic blood pressure]] over 120 mmHg.  These pressures without signs of end-organ damage (such as renal failure) are termed "accelerated" hypertension. When end-organ damage is possible or already ongoing, but in absence of raised [[intracranial pressure]], it is called [[hypertensive emergency]]. Hypertension under this circumstance needs to be controlled, but prolonged hospitalization is not necessarily required. When hypertension causes increased intracranial pressure, it is called [[malignant hypertension]]. Increased intracranial pressure causes [[papilledema]], which is visible on [[ophthalmoscopy|ophthalmoscopic]] examination of the [[retina]].
*[[Proteinuria]]
*[[Hematuria]]
*[[Renal failure]]


=== Pregnancy ===
===Brain===
{{main|Hypertension of pregnancy}}
*[[Stroke]]
Although few women of childbearing age have high blood pressure, up to 10% develop [[hypertension of pregnancy]]. While generally benign, it may herald three complications of pregnancy: [[pre-eclampsia]], [[HELLP syndrome]] and [[eclampsia]]. Follow-up and control with medication is therefore often necessary.
*[[Intracranial hemorrhage]]
*[[Transient ischemic attack]] ([[TIA]])
*[[Dementia]]

As with adults, blood pressure is a variable parameter in children. It varies between individuals and within individuals from day to day and at various times of the day. The epidemic of childhood obesity, the risk of developing left ventricular hypertrophy, and evidence of the early development of atherosclerosis in children would make the detection of and intervention in childhood hypertension important to reduce long-term health risks; however, supporting data are lacking.  


Most childhood hypertension, particularly in preadolescents, is secondary to an underlying disorder. Renal parenchymal disease is the most common (60 to 70 percent) cause of hypertension. Adolescents usually have primary or essential hypertension, making up 85 to 95 percent of cases. <ref name=aafp>{{cite web | GREGORY B. LUMA, M.D., and ROSEANN T.
