Hypertension (High Blood Pressure) is a common chronic condition which is often associated and causes other health issues such as cardiac disease. It’;s sunset can be insidious and afflicted patients may not be aware of their status until later on in life. However, an asymptomatic individual still has the same risks for developing further health problems, including of heart attacks and stroke.
Hypertension is usually asymptomatic, even at extreme levels.
Patients reporting symptoms typically report headaches, shortness of breath, nose bleeds, and tinnitus (ringing in the ears). However, these symptoms are usually non-specific and patients with poorly controlled hypertension may not manifest any symptoms at all.
Blood pressure is often taken routinely during medical consults. If concerned, ask your doctor to check your blood pressure on your next visit.
If you are aged 40 years or older, or if you have a family history of hypertension, it is advisable to have your blood pressure checked as a routine.
Alternately, there are automated blood pressure machines available for purchase over the counter for home monitoring.
Types of Hypertension
Primary (Essential) Hypertension
This reflects to the group of adults with no identifiable cause for hypertension. It is usually insidious and develops gradually over many years.
This indicates to the group where there are identifiable causes for hypertension. These causes can include:
- Hormonal imbalances eg thyroid issues
- Renal issues
- Occult tumors of the adrenal gland
- Congenital birth defects
- Obstructive sleep apnea
- Alcohol abuse
- Medication induced hypertension
- Age. Risk of hypertension increases around about age 45. It is more common in men than women though the risk profile for women approximates their male counterparts after menopause.
- Race. It has been found that the patients of black origin have a higher tendency to develop hypertension.
- Positive Family History of Hypertension. There is a genetic link for hypertension.
- High Body mass Index (BMI) (Overweight / Obese Categories) Patients with a high BMI tend to develop hypertension compared to their thin counterparts.
- Generalized Lethargy. Patients who tend to lead inactive lifestyles typically have higher heart rates and have higher BMIs, which in turn increase their risk for hypertension.
- Smoking. Smoking causes a rise in blood pressure and in the long term, causing hardening and narrowing of blood vessels. This effect is also observed in passive second hand smokers.
- Sodium (Table Salt) and Potassium Intake. Table salt, sodium chloride, when consumed in excessive amounts, causes retention of fluid within the body, in turn increasing blood pressure. Potassium, on the other hand, acts in opposition to sodium. An excess of sodium or lack of potassium will both result in blood pressure fluctuations. .
- Alcohol Intake. Alcohol causes global effects in the body. Excessive consumption of alcohol will cause Blood Pressure fluctuations.
- Associated Chronic Conditions. Chronic renal failure, diabetes, sleep apnoea etc, and even chronic stress all contribute to hypertension.
- Special Conditions. Pre-eclampsia, or Hypertension during Pregnancy, congenital defects, are examples of special conditions causing hypertension.
- Heart attacks – This is by far the most widely known complication of hypertension.
- Cerebrovascular Accidents – Commonly known as strokes.
- Aneurysms – Prolonged hypertension can cause weakening of arterial walls, causing arteries to bulge, forming aneurysms.
- Cardiac failure – Defined as the inability of the heart to pump blood around the body consumrate to the required needs, cardiac failure is a consequence of prolonged, untreated hypertension. Prolonged hypertension causes thickening of cardiac muscle, resulting in uneven contractions that eventually result in cardiac failure.
- Renal Failure – It is important to note that while renal failure can cause hypertension, hypertension in turn causes weakening of vessels within the kidneys, resulting renal failure.
- Ophthalmological complications – Damage to the tiny blood vessels within the eyeball can result in visual disturbances or even vision loss in sever cases.
- Non-specific effects – It has been documented that patients with prolonged and untreated hypertension suffer more frequently from poor mental function, memory loss, and non-specific groups of symptoms like the Metabolic Syndrome.
It is important to speak with your treating physician if you are concerned that you might have hypertension.
When seeing your physician, no special preparations are necessary though it is important that you maintain calm during the examination as anxiety can and will cause blood pressure readings to increase.
Be aware as well that the first consultation can potentially be long as there will be much to discuss prior tocoming medications to treat hypertension if present.
You should inform your physician of the following:
- Any Symptoms you have experienced – eg shortness of breath, chest pain, tinnitus etc.
- Your family history, especially if there is a family history of hypertension.
- Your current medication term.
- Your current medical history, especially if you also have associated chronic illnesses like diabetes, thyroid abnormalities, and elevated cholesterol levels.
- Your current lifestyle in all honesty – This includes diet, exercise, alcohol consumption, smoking.
- Your last Blood Pressure reading if available.
Your physician will measure your blood pressure and inform you of your Blood pressure reading.
- Blood Pressure is described with two readings:
- Systolic BP (Higher reading)
- Diastolic BP (Lower reading)
There are many categories of hypertension in relation to the systolic and diastolic blood pressure because the definition of Blood Pressure varies with age and race. Your physician will decide after taking your blood pressure, particularly after several readings on different occasions.
In certain situations, your physician may recommend 24hr monitoring of blood pressure to provide a more accurate picture of your blood pressure fluctuations throughout the day. This means you will need to perform own home BP monitoring.
Additional tests your physician might order include:
- Urine tests to check for protein in the urine
- Blood tests to ascertained cholesterol levels
- Electrocardiograms (ECGs)
Upon confirmation of the diagnoses, your physician will likely recommend lifestyle changes as the first line of treatment, followed by pharmaceutical treatment after.
