Hypotension is low blood pressure in common terms. Your blood pushes against your arteries with each heartbeat.And the pushing of the blood against the artery walls is called blood pressure.
Having a lower blood pressure is good in most cases (less than 120/80).But low blood pressure can sometimes make you feel tired or dizzy. In those cases, hypotension can be a sign of an underlying condition that should be treated.
Blood pressure is measured when your heart beats and in the periods of rest between heartbeats. The measurement of your blood pumping through your arteries when the ventricles of the heart squeeze is called systolic pressure or systole. The measurement for the periods of rest is called diastolic pressure or diastole.
Systole supplies your body with blood and diastole supplies your heart with blood by filling the coronary arteries.
Hypotension in adults is defined as blood pressure 90/60 or lower.
Hypotension is divided into several different classifications according to when your blood pressure drops.
• Orthostatic –
It is the drop in blood pressure that occurs when your transition from sitting or lying down standing occurs.It is common in people of all ages. As the body adjusts to the position change there may be a brief period of dizziness. This is like what we call sometimes “seeing stars” when we get up.
It is a drop in blood pressure that occurs right after eating. Older adults, especially those with Parkinson’s disease, are more likely to develop this type of hypotension.
• Neurally mediated –
It happens after you stand for a long time. Children experience this type more commonly. Emotionally upsetting events can also cause this type of drop in blood pressure.
It is related to shock. Shock occurs when your organs do not get the blood and oxygen they need to function properly.
For some people, low blood pressure signals an underlying problem, especially when it drops suddenly or is accompanied by signs and symptoms such as –
• Dizziness or lightheadedness
• Blurred or fading vision
• Lack of concentration
Extreme hypotension can result in this life threatening condition. Sign and symptoms include-
• Confusion, especially in older people
• Cold, clammy, pale skin
• Rapid, shallow breathing
• Weak and rapid pulse
Everyone’s blood pressure drops at one time or another. And, it often doesn’t cause any noticeable symptoms. Certain conditions can cause prolonged periods of hypotension that can become dangerous if left untreated. These conditions include –
• Pregnancy, due to an increase in demand for blood from both mother and the growing fetus.
• Large amounts of blood loss through injury.
• Impaired circulation caused by heart attacks or faulty heart valves.
• Weakness or a state of shock that sometimes accompanies dehydration.
• Infections of the bloodstream.
• Anaphylactic shock, a severe form of allergic reaction
• Endocrine disorders such as diabetes, adrenal insufficiency and thyroid disease.
• Medications might also cause blood pressure to drop. e.g. Betablockers, nitroglycerin, diuretics, tricyclic antidepressants and erectile dysfunction drugs.
• A lack of the vitamin B-12, folate and iron can keep your body distant from producing enough red blood cells, causing low blood pressure.
Even moderate forms of low blood pressure can cause dizziness, weakness, fainting and a risk of injury from falls.
And severely low blood pressure can deprive your body of enough oxygen to carry out its functions, leading to damage to your heart and brain.
Different types of blood pressure monitor are available. Monitors for home use are usually digital devices. It’s best to take several readings to check whether the problem is ongoing.
A range of lifestyle measures can help prevent low blood presssue.
These include –
• increasing fluid intake
• taking time to stand up from a sitting or lying position
• using blocks to raise the head of the bed by 6 inches
• eating small meals frequently and resting after eating
• refraining from drinking caffeinated beverages late in the day
• avoiding long periods of sitting or standing still
• avoiding suddenly changing posture or position
• wearing support stockings
Most people with low blood pressure do not need treatment. However, if hypotension starts suddenly or results from an underlying condition, a doctor will provide appropriate treatment. The treatment options will depend on the cause.
Treatment may involve a doctor-
• prescribing medication to help resolve low blood pressure
• changing a person’s medication or dosage, if they suspect that either of these is responsible.
• suggesting dietary changes, such as increasing the intake of salt or fluid.
According to Ayurveda, vata is the primary causative factor for low blood pressure, although pitta and kapha are also indirectly responsible. The vitiated vata dosha affect Oja and Rasa dhatu, leading to the reduced production and quality of Ras dhatu and Rakta dhatu, which in turn leads to hypovolaemia.
