Causes of Low Blood Pressure


The blood pressure is referred by

Systolic Pressure – The first reading, which the doctor writes in his prescription

Diastolic Pressure - This the second reading which the doctor writes.

The normal readings of these can be 120/80. Sometimes, 115/75 is also alright.

These are the general guideline readings for all.

But for some people, they may be normal, even these readings are lower.

So, only when they show noticeable problems in their body, the doctors tend to treat them for low blood pressure or
Hypotension.

Usually, the blood pressure will be low when we sleep and it may rise while we are in action like walking, running etc.

Sudden fall in the blood pressure may lead to lack of oxygen to the brain and some times be fatal also.

Following may also be the reason for lowering of the blood pressure.

·
Heavy bleeding or blood loss – If there is any heavy blood loss either during a surgery, Delivery of the baby or any internal bleeding in any part of the body or during an accident.

·
De-hydration – When some one happens to travel a long in summer and if they have uncontrollable sweating , sternous exercise, prolonged diarrhea, ie., the extreme loss of water content can cause low blood pressure

·
Pregnancy in woman - Though it is quite common in pregnant woman, they need to check the blood pressure then and there. Initially, it may be low since the blood vessels are expanding and later, it may come to normal.

·
Heart blocks or other heart problems – Repeated heart attacks (though it may be mild), low heart beat , some arterial blocks in the heart and the weakened muscles of the heart due to these may be the reason for low blood pressure.

·
Some Infections : Few infections in which the bacteria from the lungs and stomach may enter into the blood stream and due to this severe lowering of blood pressure may occur.Septic shock as it is known may be fatal also.

·
Some allergic reactions: Allergy due to food poisoning, due to some medications due to the intoxication of venoms may cause severe fall in the blood pressure, and sometimes prove fatal.

·
Endocrinal problems – Sometimes, Thyroid problems like Hypo and Hyper Thyroidism , low blood sugar (Hypo glycemia) and few Adrenal problems may also cause low blood pressure.

·
Mal nutrition – Lack of balanced diet and deficiency of Vitamin B-12 may cause the anaemic condition due to which the pressure of the blood may be lowered.

·
Swelling of some body parts(internally) may also cause low blood pressure, since the blood vessels expand in those areas.

Some medications you may take can also cause low blood pressure, including:

· Diuretics (water pills)

· Alpha blockers

· Beta blockers

· Drugs for Parkinson's disease

· Certain types of antidepressants (tricyclic antidepressants)

· Sildenafil (Viagra), particularly in combination with the heart medication, nitroglycerine

Drinking plenty of water, having a healthy , balanced diet and regular simple exercises may keep you away from the problem.

As far as possible try to avoid the above circumstances which cause the lowering of blood pressure and if you happen to have, please consult the doctor immediately.
