Reasons for low blood pressure
Hypo-tension in medical term is used for low blood pressure usually less than 90/60(systolic/diastolic). Usually low blood pressure comes with symptoms but some times it can be without symptoms. The first and the higher of these numbers stand for the pressure in the arteries during the time when the heart beats and fills up human arteries with blood. Pregnancy, heart problems, gland problems or Endocrine functions problems, blood loss, infections, allergies, dehydration and lack of proper diet are among the leading causes of low blood pressure.The second number stands for the diastolic pressure. Diastolic pressure is the pressure in the arteries when the heart rests and when it is in between two beats. However normal blood pressure is having a range 120/80 in healthy people. Low blood pressure also have some symptoms and therefore it is quite easy to get an idea when you blood pressure is falling below normal. You can then check with blood pressure meter usually called Sphygmomanometer to see what the actual readings are to get a better idea. It is very interesting to note that in athletes low blood pressure is a positive sign of good cardiovascular condition. But low blood pressure can be sign of many health problems like inadequate blood flow to the heart, brain, and other vital organs in the elderly where sometime fainting may occurs.
Postural hypotension or low blood pressure is usually caused by the positions. A high risk person should have a blood pressure chart at home so that they may know what their normal blood pressure ranges are and if they are below this normal range or above they must consult their doctors. Air travelers, whom flights are extra ordinary long, when have to stay and sit on their seats for an extra long time, usually become the victim of low blood pressure. Also as they have to sit on their seats with wrong posture for a sufficient long time they develop clots sometime.
Following are the Conditions that may cause low blood pressure:
1: Pregnancy and Low Blood Pressure : During pregnancy extra care needs to be taken at every step. During pregnancy many changes in bodies happens and one of them is that a woman’s circulatory system expands rapidly causing blood the blood pressure in the pressure to drop down than the normal range. What would happen is that normally during the first six months of pregnancy, systolic pressure or blood pressure commonly drops a few points usually somewhere from 5-10 and diastolic pressure by as much as 10 to 15 points. This need not to worry and is normal, and blood pressure usually returns to your pregnancy level after you’ve given birth.
2: Heart problems and Hypo-tension : Heart is the most important organ of the body and pumps the blood in our body so low blood pressure will definitely occur when the rate of heart beat is down than the normal and hypotension will develop. Persons having some problems with heart are at high risk of getting their blood pressure low and specially the person who are at high risks are the persons who have had some problem with their heart valves. Other high risk group which should be concerned of low blood pressure are the people who had experienced heart attack in past or have had any other sort of heart failure. These conditions prevent the blood flow resulting low blood pressure.
3: Endocrine problem :An under active thyroid or overactive thyroid can lead to many problems in human body and one of them is low blood pressure or hypotension which can cause low blood pressure. Many other glands may cause low blood pressure and the other conditions can be adrenal insufficiency (Addition’s disease), low blood sugar and, in some cases, diabetes.
4: Dehydration and Hypo-tension : In case of dehydration your body loses more water than it takes and this loss of blood means less blood to pump resulting in weakness of the body. In most severe cases of dehydration and low blood pressure a patient can also feel extreme dizziness and fatigue. This further results a drop in your blood pressure, fever, vomiting, and severe diarrhea. The overuse of diuretics and strenuous exercise can all lead to dehydration.
5: Blood loss and Low Blood Pressure : In case of heavy blood loss which can occur due to any problem like injury, surgeries or bleeding from anywhere inside the body the reduction in the amount of blood in your body occurs, which can causes a big reduction or drop in hypotension blood pressure. To know if you have hypotension you can refer to the chart easily available from you clinic or doctor.
6: Severe infection (septicemia) and Hypotension : Septicemia usually happen when an infection enters in the body. This infection can enter body by various sources like a injection, therefore care must be needed to keep infection away.
7: Severe allergic reaction (Ana phyla xis). An allergic reaction is also a quite severe situation and this is basically an allergic reaction. Allergy reactions is also among major reason and cause of low blood pressure. Common reasons which can trigger of Ana phylaxis include foods which a person is allergic too or if some body is allergic to some medications and he takes them. Other reasons can be insect venom’s and latex which can bring down hypo-tension suddenly. Monitoring the blood pressure is there fore very important in a healthy life style and whenever you feel sick or not well you must take the blood pressure reading and contact the doctor in case any thing is beyond normal.
8: Lack of nutrients in your diet. Nutrients are also very essential to our health and it also applies to hypotension. A lack of the vitamins B-12, other important nutrients, iron deficiency and other nutrients deficiency can cause anemia, a condition in which your body doesn’t produce enough red blood cells, causing low blood pressure.
