Usually abnormality refers to upper pressure or systolic. At the same time, it can be either significantly higher than the norm (hypertension) or lower than the norm (hypotension). The lower indicator remains within the limits of the permissible value, and the pulse difference does not deviate from the norm. Rarely rare changes in diastolic pressure, in which the systolic index remains within normal limits. Low lower pressure indicates a problem with the heart or nervous system and is quite rare among patients.
Low diastolic pressure
What does low blood pressure at the time of diastole mean? It depends on the specific values of blood pressure and the patient’s well-being.
Normal lower pressure for a person is considered to be in the range of 60-80. In old age, it is permissible to increase this value to 100, which is caused by the natural aging of the organism. Low lower diastolic pressure is diagnosed if this value is below 60
The easiest way to diagnose and prescribe treatment is if the lower lower pressure is accompanied by a low upper value, which directly indicates hypotension. In the case when the upper pressure is within the normal range, but no diastolic pressure is observed, a comprehensive examination is necessary to make a diagnosis and identify the cause.
To judge why the lower pressure is low, it is possible on the basis of examinations of the heart – ECG and echocardiography. What to do to normalize this indicator will also depend on the results of the survey.
First of all, with low lower pressure, the reasons should be sought in the lifestyle. This phenomenon can be observed in smokers, since nicotine violates the permeability of the walls of blood vessels and adversely affects the functioning of the heart.
Also, a reduced rate of pressure can be observed in people who abuse alcohol. Low pressure is a direct consequence of a condition called hangover. This is due to intoxication of the body, in connection with which all of its own resources go to the removal of alcohol from the body. This increases the load on the kidneys, and the pressure can drop.
In the case when the systolic index corresponds to high values (140 and higher), and the diastolic blood pressure is low, they speak of isolated systolic hypertension. In most cases, this means that lower lower pressure and elevated upper pressure are caused by the body’s response to inadequate drug therapy.
Low hypertension with elevated upper hypertension can occur with improper treatment
Among other likely causes of a decrease in diastolic pressure:
- hormone imbalance;
- endocrine disorders;
- large blood loss;
- toxic shock;
Only a specialist can accurately determine the causes and treatment that will help to normalize low lower pressure. At home, it is not recommended to take any medications, since an increase in the lower pressure entails an increase in the upper index.
Very low lower pressure is a consequence of anemia, toxic shock, or large blood loss. If in the first case the patient is aware of the diagnosis, urgent hospitalization is necessary for toxic shock and bleeding. Pressure drop below 40
Endocrine disorders, including thyroid abnormalities, can lead to a decrease in diastolic pressure only. This phenomenon is characteristic of hypothyroidism, a condition in which a small amount of thyroid hormones is produced. For accurate diagnosis, it is necessary to make an ultrasound of the thyroid gland, which will allow to evaluate the functionality of the organ.
A fairly common cause of blood pressure fluctuations is neurocirculatory dystonia, previously this disease was called vascular dystonia. Adolescents, young people under 30 and pregnant women can face such a violation. In dystonia, the autonomic nervous system cannot adequately perform its functions, so there are failures in the cardiovascular system, manifested by a change in blood pressure to a greater or lesser side, arrhythmia and pulse change. The disease is treated by a neurologist. In this case, it is necessary to improve the functioning of the nervous system so that the pressure returns to normal.
In addition, why a person has low blood pressure will also depend on what indicators of blood pressure have been observed in a patient throughout his life. If both the lower and upper pressure have always been lowered, there may be no cause for concern, since the pressure in the range of 100-110 to 60-70 can be considered a variant of the norm.
At the same time, low diastolic pressure in the elderly may indicate a depletion of the cardiovascular system and requires treatment.
Low lower pressure may be triggered by a lack of thyroid hormones.
Symptoms of the violation
Low pressure is accompanied by loss of strength, drowsiness, and chronic fatigue. Due to the lack of blood flowing to important organs, symptoms of hypoxia may appear – pallor of the face, bright shade of the lips, chills of the arms and legs. It is important to consider the value of the upper pressure. These symptoms occur if systolic pressure is in the normal range or slightly reduced.
In systolic hypertension, symptoms with low lower pressure and elevated upper are as follows:
- facial flushing;
- hand tremor;
The intensity of the symptoms depends on the specific values of the upper and lower pressure. The higher the systolic and the lower the diastolic pressure in hypertension, the greater the discomfort experienced by the person.
Manifestations in pregnant women
Low diastolic pressure in women during pregnancy is observed very often. This is due to the peculiarities of the functioning of the cardiovascular system during this period, when the heart literally works for two.
To assess the potential risks to the mother and fetus, they take into account the general well-being of the woman, the presence of associated symptoms and the exact values of blood pressure.
In the first trimester, both indicators are usually lowered. This is due to hormonal changes and toxicosis, because of which the pressure always decreases.
In the second trimester, blood pressure is usually within the normal range, but slight deviations are possible. Due to the increased load on the lower body in the third trimester, the heart begins to work intensively. At the same time pressure usually increases, but the diastolic indicator can decrease. It is important to take into account the specific values of blood pressure and associated symptoms, since a large difference (greater than 40) between upper and lower blood pressure in late juices may indicate the development of preeclampsia.
When pregnancy is necessary to take into account the well-being of women
Lower pressure in the elderly
Elderly people tend to increase blood pressure, both systolic and diastolic. This is due to the natural aging of the body.
At the same time, in a person with hypertension of 2 and 3 degrees, low diastolic pressure may be the result of a heart attack, stroke, renal failure, atherosclerosis. It is impossible to try to increase blood pressure in this case on your own, since an increase in diastolic index leads to a jump in systolic blood pressure, which in some cases can lead to the development of a hypertensive crisis.
Treatment depends a lot on the associated symptoms and the results of a comprehensive examination of the cardiovascular system.
First aid at home means that a person must take a comfortable posture, provide fresh air into the room and calm down. It is not recommended to take any drugs, since it is impossible to increase only the lower pressure with simple pills.
If such a violation is accompanied by tachycardia and pain in the heart, you can take a nitroglycerin pill or Anaprilin, but more potent drugs are forbidden to take without the doctor’s knowledge.
Treatment of low diastolic blood pressure
If the lower pressure is low, then the heart is under a heavy load. In the case when a low diastolic pressure is accompanied by a normal upper value, a possible cause is a disruption of the nervous system.
The treatment comes down to a change in lifestyle. It is necessary to avoid stress, overwork and physical overwork. It is important to normalize sleep in such a way that at least 7 hours is allotted for a night rest. At the same time, the schedule plays an important role for the nervous system. In order to avoid stress and normalize the work of the autonomic nervous system, one should go to bed at the same time every day, and also wake up.
It is important to stick to a diet, drink plenty of pure water and exercise. Often, a decrease in diastolic pressure is observed in people who spend little time outdoors. In this case, recommended daily walks before bedtime.
A low lower pressure with a normal value of the upper indicator can be observed in malignant tumors. It is impossible to identify the root of the problem on your own, so you should contact several specialists. First you should consult with a neurologist and a cardiologist. After a comprehensive examination of the heart, brain and coronary arteries, and the exclusion of ischemia and heart failure, you should consult with an oncologist.
To understand the cause of these indicators of pressure, you need to check with different specialists.
What to do if the lower pressure is low and the upper is high?
High upper pressure while lowering the lower index is called systolic hypertension. This disease develops due to a violation of the kidneys, in the presence of excess weight, against the background of atherosclerosis and hyperthyroidism. Treatment begins with an accurate identification of the cause of the disorder. Then, medical treatment of the disease that caused the blood pressure fluctuations is carried out.
If isolated systolic hypertension is an independent disease, it is necessary to consult with a cardiologist about methods for reducing blood pressure. Drug therapy for hypotensive action should be chosen with caution, since a decrease in upper blood pressure leads to a drop in the lower one, which may be accompanied by symptoms of hypoxia.
- taking drugs;
- playing sports;
- normalization of the day regimen;
- rejection of bad habits.
The diet is based on minimizing the intake of salt and heavy foods. Fruits, vegetables and dairy products should prevail in the diet. It is imperative to do daily exercises, yoga or breathing exercises. With isolated systolic hypertension, smoking and the use of alcohol is prohibited.
Prevention of blood pressure disorders completely repeats non-drug methods of treatment. A balanced diet, a healthy lifestyle and regular exercise will help prevent the development of cardiovascular disease in older age.
