Lower pressure 90 - what does this mean? Reasons to do
Problems in the deviation of blood pressure from the norm are the key to today for specialists in this field. The value of blood pressure is the basic indicator of the cardiovascular system. The pressure may vary depending on the presence of certain diseases. Maintaining a blood pressure level in the arteries is normally vital, especially for the elderly. No wonder any doctor begins an examination with what measures the patient's blood pressure.
By measuring the pressure with a tonometer, we see two figures indicating the upper pressure( systolic) and the lower pressure( diastolic).In hypertensive heart disease, both indicators increase almost identically. But it is not uncommon for a situation where the upper pressure is normal or slightly overstated, while the lower one rises much more strongly. In this article, let's try to figure out if the bottom pressure is 90, what does this mean? Let's understand. 
What is blood pressure?
Under arterial pressure, doctors understand the level of pressure with which blood acts on the walls of blood vessels. The upper( systolic) occurs when the left ventricle is contracted( systole).Lower( diastolic) index of relaxation( diastole).Normally, the pressure of an adult healthy person ranges from 110/70 to 130/90 mm. The upper figure is also called "cardiac" pressure, since it is an indicator of the strength of the heartbeat. The lower figure is in direct proportion to the state of the vessels and the work of the kidneys. The substance called "renin" is synthesized by the kidneys. It affects the vascular tone, which naturally affects the lower pressure, which is sometimes called "renal."At a pressure of 130/90, doctors talk about the upper limit of the norm. Sometimes such a value may indicate a tendency to develop hypertension. Pressure indicators also increase during physical exertion, emotional outbursts and stressful states. If, for a long period of time, you notice a persistent increase in pressure, then, most likely, this is the onset of hypertension.
So, the bottom pressure of 90 - what does this mean? 
Diastolic( lower) pressure
The level of blood pressure in everyone can have a value, but still there are averaged figures for an adult whose deviation is considered abnormal. The optimum value of this indicator should be from 70 to 90 mm Hg. If the level of diastolic pressure is kept at a value of 90 for a long period, what does this mean? With an increase in the same time and systolic pressure, this may indicate an initial stage of hypertension.
In the case when the lower pressure rises irrespective of the upper parameters, one should be examined for the presence of pathologies of various kinds. This condition can be caused by various factors, for example, kidney pathologies, adrenal gland disorders, endocrine diseases( thyroid dysfunction, pituitary gland), spinal problems( osteochondrosis, intervertebral disc hernias), atherosclerotic vascular lesions, defects or heart tumors. There may be other causes: chronic stress, psychotrauma, abuse of alcoholic beverages and stimulants( medicines, dietary supplements, energy drinks), excessive tobacco cravings, habit of overeating, errors in eating behavior( eating fried, fatty foods, pickles,canned food, smoked products).What is the bottom pressure of 90?We will discuss this further. 
High diastolic pressure: what is the danger?
Here everything depends on the reasons causing a steady increase in the lower pressure. Depending on this, either existing diseases can worsen, or new ones arise, conditioned by the conduct of an unhealthy lifestyle. In the absence of necessary treatment, the disease state will progress, creating a threat to vital organs. What is the bottom pressure of 90?This is a frequent question of patients, because a constant increase in diastolic pressure adversely affects the blood supply of all organs and systems of the body. This leads to a violation of their nutrition, and then to sclerotic degeneration. In organs, gradually healthy tissues die and are replaced by connective tissue, which leads to irreversible disturbances in the functioning of organs. Changes can affect the heart and kidneys, as well as the liver and brain. With the replacement of nerve cells in the brain, connective tissue is impaired memory and intelligence.
Many people have a lower pressure of 90, what does this mean? 
Symptomatology
For most hypertensive patients, the onset of the disease is asymptomatic and they do not even guess about it. The person feels relatively healthy and vigorous, and insignificant errors in the state of health write off for fatigue or overstrain at work. The problem with the pressure in most cases is revealed quite accidentally during an ordinary campaign in a polyclinic. With the passage of time, in the absence of treatment, hypertension( increased pressure) develops, which is fraught with sharp pressure jumps and the emergence of the danger of hypertensive crisis.
How to lower the lower pressure, if it is 90, consider below.
The condition is accompanied by an intense headache, sometimes with nausea and vomiting, as well as flashing "flies" and dizziness. The nervous system can respond with convulsive seizures and the appearance of hallucinations. In addition, a disorder of the peripheral nervous system can provoke temporary paresis of the limbs, loss of sensitivity in certain areas of the body. In general, the nature of damage in the onset of hypertensive crisis depends on where the pathology was localized: if there were headaches, then a stroke is possible, if the heart was sick, myocardial infarction. If you have symptoms of hypertensive crisis before the arrival of an ambulance, you must put the patient on a flat surface, lifting his head, you can also try to lower blood pressure with drugs of quick action.
The cause of the lower pressure 90 can only be detected by a doctor. 
How to measure?
Diagnosis and treatment of hypertension directly depend on how, how and how correctly you measure the pressure. There are several types of modern tonometers:
- Having a mechanical principle of operation.
- Semi-automatic devices.
- Fully automated( electronic) devices.
When using the first and second option, it is necessary to monitor the correct cuff placement and to have a certain skill in using the device, listening to heart tones.
If you comply with all the rules, you can get a fairly reliable result. Electronic models are similar in principle to the work, and the result of measurements is displayed on the scoreboard. The electronic tonometer greatly facilitates the patient's whole process of measurement and gives a more accurate result. Unfortunately, such devices often fail, mechanics in this sense are more reliable.
We are considering the causes of the lower pressure 90 and what to do about it. 
How to measure?
But regardless of the device you are using, when measuring pressure, the following rules should be observed:
- A complete relaxation of the body is necessary.
- Before you measure pressure, you must exclude physical activity and eating.
- You need to take a comfortable pose.
- It is necessary to measure the pressure level on both hands with an interval of 5-10 minutes.
In the case where frequent measurements are very different from each other, a series of control measurements must be carried out within a week.
Bottom pressure 90 - what to do?
In the presence of the underlying disease, which causes a persistent increase in the lower pressure, it is necessary to take all measures to cure it. For other reasons, you should adjust the diet, get rid of tobacco addiction, stop using stimulants, spend enough time outdoors and give the body the physical strength to exercise regularly.
Why the lower pressure is 90, it is better to check with your doctor.
Without consulting the attending physician, prescribing medications is strictly not recommended. As well as self-medication on the basis of folk methods.
Drugs
In consultation, the doctor can prescribe one of the following diastolic pressure medications: Atenolol, Metoprolol, Bisoprolol, Lozartan, Verapamil, Nifedipine, Enalapril, Perindopril, and others. In addition, a diuretic( a diuretic) can be administered simultaneously with potassium preparations: Hypothiazide, Diacarb, Lasix, Panangin, Asparcum, Triamteren. To stop the attacks of hypertensive crisis, quick-response medicines are used: Corinfar, Captopril.
In conclusion
Once again we remind that without consulting a doctor independently prescribe yourself a treatment with these drugs is not possible, it is dangerous for life. If you suspect a hypertensive crisis, you should immediately call an ambulance. In conclusion, once again, we say that the treatment of hypertension is a laborious and time consuming process. The outcome directly depends not only on drug therapy, but also on the degree of responsibility of the patient.
This is what it means - lower pressure 90.
