Blood pressure warning – what causes low blood pressure? Are you at risk of hypotension?
Low blood pressure is a reading of 90/60mmHg or less, according to the NHS.While the condition, which is also known as hypotension, doesn’t always cause symptoms, there are some warning signs to look out for Lightheadedness, blurred vision and a general feeling of weakness could all be signs of low blood pressure If you get low blood pressure symptoms when you stand up or suddenly change position, you could have postural hypotension, the NHS added But, what actually causes the condition? A vitamin B12 deficiency or underlying heart problem could all contribute to your hypotension, it’s been revealed You could be at risk of low blood pressure if you don’t have enough vitamin B12 in your diet, according to the American Heart Association You can lower your risk by eating more vitamin B12 foods, include eggs, shellfish and some dairy products Certain medications could also cause your blood pressure to drop. These include diuretics and other drugs that treat hypertension Some beta blockers, erectile dysfunction drugs and alcohol could also reduce your blood pressure, the charity said “A decrease in blood volume can also cause blood pressure to drop,” it added“A significant loss of blood from major trauma, dehydration or severe internal bleeding reduces blood volume, leading to a severe drop in blood pressure “Anaphylactic shock is a sometimes-fatal allergic reaction that can occur in people who are highly sensitive to drugs such as penicillin, to certain foods such as peanuts or to bee or wasp stings “This type of shock is characterised by breathing problems, hives, itching, a swollen throat and a sudden, dramatic fall in blood pressure ”Prolonged bed rest, pregnancy, or endocrine problems could also lead to hypotension Your blood pressure reading will have two readings; a systolic and diastolic pressure The systolic blood pressure – the first number – is the force at which your heart pumps blood around the body The diastolic blood pressure – the second number – is the resistance to blood flow in the blood vessels An ideal blood pressure is considered somewhere between 90/60mmH and 120/80mmHg.All adults over 40 are advised to have their blood pressure checked at least every five years
