Increased diastolic pressure is not always manifested by pronounced clinical signs and may not be noticed by a person for a long time, especially if the upper pressure is low. Many people who have not yet tasted the fullness of the insidiousness of hypertension, do not even attach importance to the diastolic value.
Meanwhile, the state when the lower pressure is high, our body can signal the danger hanging over it. As you know, for both pressure indicators, there is a concept of norm, or reference values. So, going beyond them means pathology. This situation is worth looking into in detail.
Reasons for increasing the diastolic index
The value of the lower pressure is fixed with diastole – a relaxed state of the myocardium, which allows the heart chambers to fill with blood. This parameter is affected by the resistance of peripheral vessels-capillaries. Deterioration of their elastic properties, their spasm or clogged with cholesterol are the most common causes of high lower pressure.
The reference point for normal blood pressure parameters (BP) is the values at which the largest number of people feel healthy and workable.
To know at what numbers on the blood pressure monitor you should show concern and consult a doctor, you should compare them with the reference values of blood PRESSURE. They are considered normal:
100-130 mm of mercury in systole;
70-90 mm – for diastolic blood PRESSURE.
Remember – if the diastolic blood PRESSURE (DBP) exceeds 90 mm-this means that the person has a high lower pressure.
Why is it higher than it should be?
Reference values of blood PRESSURE are the first evidence of health, well-coordinated work of the heart and blood vessels, and the absence of organic or systemic pathologies. Accordingly, if the blood PRESSURE exceeds the norm for at least one of the indicators, it indicates problems with human health.
To accurately determine the reasons why the lower pressure has become high, you should be examined in a medical institution – take blood tests, pass an ECG and ultrasound of the abdominal cavity and kidneys.
All this is necessary to pass in order to find out which of the reasons was the instigator of high lower pressure, why only the lower one rose, and what should be the treatment. Precipitating factors are many and they can be connected:
with abnormalities of the kidneys and dysfunction of the adrenal glands;
with diseases of the connective tissue and musculoskeletal system (for example, cervical osteochondrosis);
vascular diseases (diabetic angiopathy and nephropathy, atherosclerosis, etc.) and heart;
dysfunction of the system that regulates blood flow;
metabolic disorders and other organic or systemic disorders;
with prolonged use of certain medications that indirectly increase blood pressure;
with physical or mental fatigue.
Only a deep and thorough diagnosis will help to assess the situation and find out why the lower blood pressure has become high, and what to do in such a situation to normalize it.
The hormone estrogen, secreted by the ovarian follicular apparatus, as well as by the adrenal glands and other extra-gonadal organs, serves as a deterrent to minimize the likelihood of developing CVD (cardiovascular diseases), in particular, atherosclerosis in women. Due to insufficient production of these hormones (for example, an imbalance during menopause) women may experience various pathological conditions, including high lower blood pressure.
Hormonal changes in the female body that accompany the first months of pregnancy can also provoke an increase in diastolic blood pressure, often synchronously with the upper ONE. If the lower pressure remains high in the second half of pregnancy, its cause should be sought in preeclampsia, a condition that was previously called late toxicosis. It usually requires hospitalization and medical supervision to prevent dangerous consequences for the baby.
Another common cause of high lower blood pressure in women is pathological processes in the thyroid gland, characterized by intensive production of hormones that stimulate the sympathetic nervous system. This results in a rapid pulse, incomplete relaxation of the myocardium in diastole, and spasms of peripheral vessels.
There are also external reasons:
lack of physical activity – an untrained heart does not cope well with the function of “pumping” blood, reacts with an abnormal increase in the pulse rate to any load, which is why the heart chambers do not have time to fully relax and tension is created in the bloodstream;
frequent stress, in which the blood vessels narrow under the influence of adrenaline released into the blood;
bad habits that Deplete the heart muscle faster;
improper nutrition – long breaks in meals, unhealthy snacks with sweet or salty, smoked or rich foods contribute to the deposition of cholesterol in the walls of blood vessels, which gradually narrows their lumen and worsens throughput;
overeating, excess weight-this creates an extra load on the heart, leads to a violation of blood circulation and metabolism, which ultimately affects the tone of blood vessels;
Lack of sleep and lack of proper rest also often provoke high lower blood pressure, so women who are in a stressful rhythm of life are more likely to ask about this condition-what is it, illness or fatigue. And both answers are correct – this is overwork, which can end in illness.
For the male half of humanity, the same causes of high DBP are relevant as for women, of course, except for pregnancy and menopause, but the frequency of prevalence in men is dominated by:
physical, psychoemotional, or mental strain;
family predisposition to CVD, congenital heart defects;
eating disorders, lack of exercise, excess weight;
addiction to alcohol.
Men are much earlier than women are faced with such dangers as atherosclerosis and the pathological conditions caused by it – arterial hypertension, ischemia of the heart and brain with further progression to a heart attack or stroke.
Diabetes mellitus and kidney dysfunction are frequent instigators of increased lower blood pressure in men. All these situations require a thorough examination, medical supervision, and long-term treatment.
What does high blood PRESSURE mean?
And yet, what does high lower blood pressure tell the doctor, what does it mean when making a patient’s history? If we are talking about really high numbers, doctors define the condition as arterial hypertension.
When high lower blood pressure is detected with normal upper blood PRESSURE, it means that a person has developed isolated diastolic hypertension.
A DBP value that does not exceed 90 mm Hg is not a sign of arterial hypertension if the systolic index is normal. The very same value-90 mm-is borderline in determining hypertension, which is diagnosed with indicators above 140 to 90.
Attention should be paid to the situation when the DBP is 90, and the sad IS only 100-110. If this is not an innate physiological feature – then it is clearly a pathological combination of indicators, since the pulse difference (between the values of SBP and DBP) is too small. This may indicate violations of nerve cell conduction, heart failure, and other pathological conditions.
The value of diastolic pressure equal to 100 mm is without any reservations a sign of arterial hypertension. According to cardiological studies, about a fifth of patients suffering from arterial hypertension face its isolated form of diastolic blood PRESSURE.
This situation is complex both in diagnostic and therapeutic terms – the difficulty is not only the search for what can cause high lower blood pressure, but also ways to normalize it. Medicines that have the property of reducing one of the pressure indicators in isolation have not yet been invented. Conventional hypotensive therapy affects both values. Therefore, the patient should prepare for the fact that the selection of a treatment regimen will take several weeks, and it will be adjusted throughout the therapeutic process.
Do I need treatment?
As is already clear from the above, high lower pressure can be both a physiological feature of a person, and a sign of cardiovascular and other pathological conditions. You should consult your doctor about whether it needs treatment.
In the case of a slight increase in DBP, the patient’s state of health is a guide – if it does not cause discomfort and anxiety, diastolic pressure up to 90 mm Hg does not require treatment. Although it is not superfluous to observe the condition at such figures – this is still the maximum permissible limit of the norm.
With higher numbers, when it comes to arterial hypertension, the body needs to stabilize the indicators, although this does not necessarily have to be medication. The specialist who can assess the situation based on laboratory blood tests, other studies, and the patient’s medical history is the best person who knows how to reduce the DBP.
What to do at home?
Patients who consider the doctor’s office the last resort to go to will always look for ways to deal with their illness at home. This approach is fundamentally wrong, and without consulting a doctor, nothing should be recommended. But it is really worth giving up self-treatment decisively. Especially if the situation is non-standard – high lower pressure.
