High blood pressure affects more than 1 billion people worldwide and is the commonest cause of cardiovascular disease such as stroke, heart attack and kidney failure.
It's not clear what causes high blood pressure. The vast majority of patients with hypertension are asymptomatic and have what is called primary hypertension, which simply means that no underlying cause of their hypertension (such as an adrenal tumour or some form of kidney disease) can be explained.
Most clinical guidelines would recommend that patients should be screened for underlying causes of hypertension with simple investigations and that treatment decisions should be based upon an estimation of an individual’s overall risk of developing cardiovascular disease.
It is well worth seeing a hypertension specialist even at such an early stage in order to be more thoroughly evaluated for underlying causes of hypertension and to undertake comprehensive assessment of the patient’s future risk of developing cardiovascular disease such as stroke / heart attack or kidney failure.
Low blood pressure is not uncommon and is increasingly recognised as a cause of faints/dizzy spells & lethargy.
Low blood pressure causes light-headedness or dizziness, particularly when getting up from a seated/lying position and also when standing for prolonged periods. Patients who suffer with this problem can have faints (and even fits in some instances) due to very low blood pressure.
It is very important that such patients are investigated appropriately to rule out reversible causes of hypotension. Thereafter management requires medical expertise and takes a two pronged approach:
