High blood pressure (HBP)
High blood pressure (HBP) is a serious condition that can lead to coronary heart disease (also called coronary artery disease), heart failure, stroke,
kidney failure, and other health problems.
"Blood pressure" is the force of blood pushing against the walls of the arteries as the heart pumps blood. If this pressure rises and stays high over time, it can damage the body in many ways.
Hypertension (HTN) or high blood pressure, sometimes called arterial hypertension, is a chronic medical condition in which the blood pressure in the arteries is elevated. This requires the heart to work harder than normal to circulate blood through the blood vessels. Blood pressure involves two measurements, systolic and diastolic, which depend on whether the heart muscle is contracting (systole) or relaxed between beats (diastole). Normal blood pressure at rest is within the range of 100-140mmHg systolic (top reading) and 60-90mmHg diastolic (bottom reading). High blood pressure is said to be present if it is persistently at or above 140/90 mmHg.
Hypertension is classified as either primary (essential) hypertension or secondary hypertension; about 90–95% of cases are categorized as "primary hypertension" which means high blood pressure with no obvious underlying medical cause.[1] The remaining 5–10% of cases (secondary hypertension) are caused by other conditions that affect the kidneys, arteries, heart or endocrine system.
Hypertension is a major risk factor for stroke, myocardial infarction (heart attacks), heart failure, aneurysms of the arteries (e.g. aortic aneurysm), peripheral arterial disease and is a cause of chronic kidney disease. Even moderate elevation of arterial blood pressure is associated with a shortened life expectancy. Dietary and lifestyle changes can improve blood pressure control and decrease the risk of associated health complications, although drug treatment is often necessary in people for whom lifestyle changes prove ineffective or insufficient.
Your blood pressure reading uses these two numbers, the systolic and diastolic pressures. Usually they are written one above or before the other. A reading of
120/80 or lower is normal blood pressure
140/90 or higher is high blood pressure
Between 120 and 139 for the top number, or between 80 and 89 for the bottom number is prehypertension
Signs and symptoms
Hypertension is rarely accompanied by any symptoms, and its identification is usually through screening, or when seeking healthcare for an unrelated problem. A proportion of people with high blood pressure reports headaches (particularly at the back of the head and in the morning), as well as lightheadedness, vertigo, tinnitus (buzzing or hissing in the ears), altered vision or fainting episodes.
On physical examination, hypertension may be suspected on the basis of the presence of hypertensive retinopathy detected by examination of the optic fundus found in the back of the eye using ophthalmoscopy.Classically, the severity of the hypertensive retinopathy changes is graded from grade I–IV, although the milder types may be difficult to distinguish from each other. Ophthalmoscopy findings may also indicate how long a person has been hypertensive.
causes high blood pressure
Two forms of high blood pressure have been described -- essential (or primary) hypertension and secondary hypertension. Essential hypertension is a far more common condition and accounts for 95% of hypertension. The cause of essential hypertension is multifactorial, that is, there are several factors whose combined effects produce hypertension. In secondary hypertension, which accounts for 5% of hypertension, the high blood pressure is secondary to (caused by) a specific abnormality in one of the organs or systems of the body. (Secondary hypertension is discussed further in a separate section later.)
Essential hypertension affects approximately 72 million Americans, yet its basic causes or underlying defects are not always known. Nevertheless, certain associations have been recognized in people with essential hypertension. For example, essential hypertension develops only in groups or societies that have a fairly high intake of salt, exceeding 5.8 grams daily. Salt intake may be a particularly important factor in relation to essential hypertension in several situations, and excess salt may be involved in the hypertension that is associated with advancing age, African American background, obesity, hereditary (genetic) susceptibility, and kidney failure (renal insufficiency). The Institute of Medicine of the National Academies recommends healthy 19 to 50-year-old adults consume only 3.8 grams of salt to replace the average amount lost daily through perspiration and to achieve a diet that provides sufficient amounts of other essential nutrients.
Genetic factors are thought to play a prominent role in the development of essential hypertension. However, the genes for hypertension have not yet been identified. (Genes are tiny portions of chromosomes that produce the proteins that determine the characteristics of individuals.) The current research in this area is focused on the genetic factors that affect the renin-angiotensin-aldosterone system. This system helps to regulate blood pressure by controlling salt balance and the tone (state of elasticity) of the arteries.
Approximately 30% of cases of essential hypertension are attributable to genetic factors. For example, in the United States, the incidence of high blood pressure is greater among African Americans than among Caucasians or Asians. Also, in individuals who have one or two parents with hypertension, high blood pressure is twice as common as in the general population. Rarely, certain unusual genetic disorders affecting the hormones of the adrenal glands may lead to hypertension. (These identified genetic disorders are considered secondary hypertension.)
The vast majority of patients with essential hypertension have in common a particular abnormality of the arteries: an increased resistance (stiffness or lack of elasticity) in the tiny arteries that are most distant from the heart (peripheral arteries or arterioles). The arterioles supply oxygen-containing blood and nutrients to all of the tissues of the body. The arterioles are connected by capillaries in the tissues to the veins (the venous system), which returns the blood to the heart and lungs. Just what makes the peripheral arteries become stiff is not known. Yet, this increased peripheral arteriolar stiffness is present in those individuals whose essential hypertension is associated with genetic factors, obesity, lack of exercise, overuse of salt, and aging. Inflammation also may play a role in hypertension since a predictor of the development of hypertension is the presence of an elevated C reactive protein level (a blood test marker of inflammation) in some individuals.
HOMEOPATHIC TREATMENT
Argentum nitricum: If blood pressure rises with anxiety and nervousness, this remedy may be indicated. “Stage fright” or anticipation of a stressful event can bring on dizziness, headache, diarrhea, and a pounding pulse. People who need this remedy are typically warm-blooded, imaginative, impulsive, claustrophobic, and have strong cravings for sweets and salt.
Aurum metallicum: This remedy is sometimes indicated for serious people, focused on career and accomplishment, with blood pressure problems related to stress. Worry, depression, or anger may occur, especially when these people feel they have made a mistake or failed in some way. A general tendency to feel worse at night, and a strong desire for alcohol, sweets, bread, and pastries are other indications for Aurum.
Belladonna: This remedy is indicated when symptoms come on suddenly, with great intensity and heat. The person’s face is flushed, with dilated pupils, and pulsations and throbbing may be felt in various parts of the body. Despite the general heat, the person’s hands and feet may be cold. Vertigo and pounding headaches, worse from jarring and worse from light, may also occur.
Calcarea carbonica: This remedy is often helpful to people with high blood pressure who easily tire and have poor stamina. They are typically responsible types, who feel overwhelmed when ill and fear a breakdown. Palpitations and breathing problems can be worse from walking up a slope or stairs, and also when lying down. A general chilliness with clammy hands and feet (the feet may heat up in bed at night) and sweat on the head during sleep are other indications. The person may have cravings for sweets and eggs, and tend toward weight problems.
Glonoinum: A flushed face with a pounding headache and visible throbbing in the blood vessels of the neck may indicate a need for this remedy. The chest can feel congested or hot, with a pounding or irregular heartbeat. The person is worse from moving around, after heat and sun exposure, and after drinking alcohol. A feeling of “being lost in a familiar place” is a strong indication for this remedy.
Lachesis: A person who needs this remedy typically is intense and talkative, with inner passion and agitation that need an outlet—a “pressure-cooker.” The person may have a strong fear of disease, and feelings of suspicion, revenge, or jealousy are common. The person may also have heart or artery problems, look flushed or purplish, and feel constriction in the chest, with pulsations in many areas. Feeling worse after taking a nap or on waking in the morning, and a strong intolerance of clothing around the neck (or any kind of restriction) are other indications for Lachesis.
Natrum muriaticum: A person who needs this remedy seems reserved and responsible, but may have very strong feelings (of grief, disappointment, anger, lingering grudges, a fear of misfortune) inside. Headaches and palpitations are common, as well as a feeling of tension (even coldness) in the chest. The person feels worse from being in the sun, worse around mid-morning, and better from being alone in a quiet place. A craving for salt and strong thirst can help to confirm the choice of this remedy.
Nux vomica: A person who needs this remedy is usually impatient and driven—easily frustrated, angered, and offended. A strong desire for coffee and other stimulants, sweets, strong foods, and alcohol or drugs may aggravate blood pressure problems. Palpitations, constricting feelings in the chest, constipation, and hemorrhoids are often seen. The person is typically sensitive to light, noise, odors, and interference.
Phosphorus: A person who needs this remedy usually is sensitive, suggestible, and sympathetic, with a tendency toward weakness, dizziness, a “spaced-out” feeling, and fearfulness. Nosebleeds, facial flushing, palpitations, and a feeling of heaviness or pain in the chest, and left-sided problems are often seen. A strong desire for cold drinks and refreshing things, and a marked improvement after eating and sleeping are other indications for Phosphorus.
Plumbum: This remedy is indicated for people with degenerative problems of the nerves and hardening of the arteries. Chest tightness and palpitations are often worse when lying on the left side. Contractures, paralysis, and nerve or muscle problems are also likely. The person may have a history of heavy drinking and “high living”—becoming apathetic or depressed when physical debility and memory problems develop.
Sanguinaria: A feeling that blood is rushing to the head, with flushed red cheeks and pulsing in the neck, may indicate this remedy. The person may have headaches or migraines (usually on the right and worse from light and noise). Right-sided neck and shoulder problems, allergies, heartburn, and digestive problems are often seen, and burning pains are typical. Symptoms are worse from motion, and relief may come from being in the dark and sleeping. A craving for spicy food, and a tendency to feel worse from eating sweets are other indications for Sanguinaria.
