1Low Blood Pressure Causes – Dehydration

There are a lot many people who experience low blood pressure but because of the lack of awareness they do not know the reasons and even the symptoms of low blood pressure. This leads to other health problems in the long run. If it is not detected and countered in time it can cause severe damage to the different organs of the human body. Therefore, it is very important to learn about the various causes of low blood pressure and the measures to control it. A lot many problems can be avoided if blood pressure is kept under control.

The most common reason of low blood pressure is dehydration. This may come as a surprise for you. Most of us do not take care to remain hydrated and take dehydration for granted. For the information of all of you, this is the basic cause of low blood pressure. Dehydration can be defined as the loss or the lack of the fluid and necessary lasts required by the body. Dehydration can occur due to various reasons. One of the reasons is that you are not taking enough water or liquid intake to keep your body hydrated. It is recommended that a person must drink at least 3 liters of water in a day to remain fully hydrated, very few of us know this and only little of these people actually practice this regime. Another cause of dehydration is diarrhea. Due to diarrhea, the fluid and essential salts for the body are drained from it thus leaving the patient dehydrated. This is the reason that the doctors advise large amount of fluid intake to the patient of diarrhea. Another reason of dehydration is sweating. When you are working and the temperature is high and the weather is warm, your body sweats to keep it at a normal level. When sweating, the fluids and salts are drained from the body which leads to dehydration. So when the body loses fluids it leads to low blood pressure.

Therefore, lager amount of water intake is advised in summers as well as in winters. Most of us reduce our water intake during winters as our body does not give us signal of fluid loss. On the contrary in summers when the body is dehydrated you will feel thirsty and your mouth will get dry. So the more water you drink the more problems you will be able to avoid. If you keep your body hydrated you are less likely to experience low blood pressure. This is the reason that water pills such as Lasix are given to the people with blood pressure problem in order to maintain normal blood pressure level.

One thing that must be noted here is that fluid intake does not mean that you should take caffeinated drinks or carbonated drinks such as tea, coffee or soda. It means that you must drink maximum water or fruit juices. If you have low blood pressure problem then you must avoid dehydration as much as possible

2Low Blood Pressure Problems

Due to hypertension being very common, you might ask yourself that will it not be better if you have low blood pressure. The answer to this is no, because low blood pressure is associated with problems of its own.
The body has a feedback mechanism with the help of which, it tries to keep the blood pressure in normal limits. If in any case, the blood pressure is deranged, high or low, it may be harmful for the body.

Low blood pressure is often not seen as the major cause of the problem, but is rather considered to be a major problem of many causes. Dehydration, for example after diarrhea or excessive sweating, can cause a decrease in blood volume, which can further lead to a rapid decline in blood pressure. Moderate decline in blood pressure if not controlled, can lead to a severe condition, where the kidneys will not receive proper amount of blood flow and they can go into acute renal failure.

Like the kidneys, low blood pressure can also affect the brain, and the person might not receive proper oxygenation for the brain tissues, because of improper blood supply, which can further lead to headache, dizziness, vertigo and fainting. If not promptly treated, this can lead a person to coma.

One of the major problems which can lead to a rapid fall in blood pressure is a hemorrhagic shock. This is very common nowadays, due to the increased number of road traffic accidents, suicidal rates, and ongoing criminal activities. A person here has an excessive loss of blood, which leads to a decrease in blood volume and hence, an acute fall in blood pressure. Death can ensue, if the blood volume is not restored back, because an acute decline in blood pressure means that the vital organs of the body, such as the brain, heart, kidneys and liver are going into acute failure.

To combat hypertension, many drugs are being prescribed such as Calcium Channel Blockers, ACE inhibitors, diuretics and beta blockers. The major problem that these drugs are associated with, is that, in the process of lowering the blood pressure of a hypertensive patient, at times, they take it a below normal. This can lead to the person showing the symptoms of hypotension, i.e. low blood pressure, and often falling because the legs are not receiving adequate amount of blood supply due to low blood pressure.

Since immunity in the pediatric age group is not that well developed, they are often prone to having diarrhea. This makes them lose a huge amount of fluid in the form of urine, stools, vomiting and sweat. Hence, they also face a drop in blood volume and consequently, blood pressure. If these children are not given proper and timely treatment, they may end up in a very critical condition.

Therefore, people need to get familiar with all these problems related to low blood pressure, so that their lives may be spent in a risk free fashion.

3Low Blood Pressure Chart

Low blood pressure is defined, as blood pressure which is considered to be below the normally expected range, for a particular person, in a given environment. So that the blood pressure stays within the normal limits and does not fall too low, the following is a blood pressure chart, which is applicable to adult men and women. After studying the chart, a discussion will be done upon how to monitor, and keep the blood pressure at normal ranges.Low Blood Pressure Chart

Normal Blood Pressure: 115/75 mm Hg

Low Normal Blood pressure: 100/60 mm Hg considered to be normal for athletes and children

Hypotension 90/60 mm Hg

Symptomatic Hypotension 80-60/60-45 mm Hg patient starts to notice the symptoms of nausea, dizziness,
tiredness, fainting, weakness,
sleepiness, blurred vision and confusion.

Comatose condition and death 50/35 mm Hg

While the above mentioned chart readings are quite accurate for showing hypotension, they have a great variation in terms of age, sex and body weight. Whatever the case may be, keeping the blood pressure in ideal limits (115/75 mm Hg) should be the ultimate aim of a person.

Unlike high blood pressure, the diagnosis and presentation of low blood pressure relies a lot upon the presentation of signs, and symptoms, of low blood pressure. In a situation where the patient is showing no symptoms of low blood pressure, the doctors take a stand to keep the patient under observation.

There are various causes of low blood pressure. They include pregnancy for women, dehydration, loss of fluids, through vomiting and diarrhea and some heat/allergic reactions. Moreover, low blood pressure can also be caused if a hypertensive patient is taking medications to lower his blood pressure.

The levels in the blood pressure chart may vary from person to person. Some individuals may start showing the symptoms of dizziness and fainting, at a blood pressure level of even 100/70 mm Hg while for some, even a blood pressure of below 90/60 mm Hg may appear to be normal. Now, if a patient is experiencing the symptoms of low blood pressure, he should increase his salt intake, and should have adequate hydration for himself. Drinking considerable amount of water particularly in the summer season, and a diarrhea illness, may keep your body adequately hydrated and may not let your blood volume increase and hence the blood pressure will fall down.

Pregnancy is also considered to be one of the important causes for a fall in blood pressure. In this case, a pregnant woman should record her blood pressure readings every now and then, because a derangement of the blood pressure both in the high or the low scale can be harmful for the mother as well as the baby. If she is noticing the symptoms of low blood pressure recurrently during her pregnancy, it is advised to her to keep herself hydrated with plenty of fluids, and she should keep massaging her legs in order to help increase the blood flow to her body.
