For most of us, having a high blood pressure causes immediate concern because we are all too familiar with its possible complications and effects on the body. It is common knowledge for the majority that having a high blood pressure can result to malfunction and damage to major internal organs, disability, or even death from a fatal heart attack.
If your blood pressure drops to abnormally low levels, also known as hypotension, there are dangers just the same, and that’s why we need to know the symptoms and causes of low blood pressure. Hypotension, or the physiological state of abnormally low blood pressure, is something we should all be concerned about because just like hypertension, this can be a sign of serious disorders which can lead to organ damage and life threatening consequences.
In preventing the dangers of low blood pressure, the first thing you need to know is “how low can you go?” before it can be considered dangerous. Typically a blood pressure of 120/80 or 115/75 is considered ideal, so a blood pressure of 90/60 or 115/50 is considered lower than normal. However since this can vary from person to person depending on physical state (athletes and people in peak physical condition have a lower blood pressure) and a whole range of other factors, and in cases where you don’t have a way to measure the blood pressure, you’ll have to rely on the symptoms.
Some of the most common signs of hypotension include dizziness, nausea, thirst, fatigue, lack of concentration, blurred vision, headache, light headedness, and irregular heart beat. While low blood pressure isn’t always serious, for good measure it would be best to see your doctor if you experience any of these symptoms just to be on the safe side.
In general, the top medical conditions that you need to watch out for to prevent low blood pressure include:
Pregnancy – blood pressure drops during pregnancy because of the expansion of the circulatory system. This is expected, and the pre-pregnancy levels will return after giving birth
Dehydration – when you lose water, either by the use of diuretics or through exercise, your blood volume drops, and this causes low blood pressure which will manifest through weakness, dizziness, extreme thirst, and fatigue.
Blood loss – a decrease in blood volume can cause a sudden drop in blood pressure
Lack of nutrients – deficiency in vitamin B12 and folate prevents the body from producing enough red blood cells
Heart problems that prevent your body from circulating enough blood (bradycardia, heart valve problems etc.)
High blood pressure medications, endocrine problems, old age (above 65), severe infection and allergic reaction, and certain diseases like diabetes are also some of the risk factors. If you experience any of these symptoms or find yourself in any of the conditions mentioned, consult a medical practitioner right away.
