Blood pressure, nausea and headache: causes, methods of diagnosis and treatment

Causes of pressure, nausea, headache

Acute headaches, nausea, weakness and deterioration in health, as well as various heart rhythm disturbances are symptoms that may indicate both high and low blood pressure. Normally, this figure is 120/80 mm. rt. Art., but in some people it remains at a higher or lower level. When measuring it, various factors are taken into account, but chronic hypertension or hypotension cannot be considered normal.

High blood pressure

Hypertension is an increase in blood pressure. It often occurs in a chronic form and can be diagnosed at any age. Blood pressure indicators with constant hypertension remain within the range of 140∕90 mm or more. rt. Art. Doctors recommend exercising with caution if you have this disease, avoiding stress, and regularly measuring your blood pressure at home.

Causes of hypertension

The main cause of hypertension is weakness of blood vessels and decreased elasticity of their walls. With a sharp increase in blood pressure, they cannot adapt to the load. This can happen in the warm season, during physical activity, under stress and nervous tension. In addition, chronic hypertension can be diagnosed, which manifests itself in both adults and children. Its causes may be:

congenital or acquired diseases of the heart and blood vessels;
excess weight, which increases the load on the heart muscle;
abnormal physical activity;
age-related changes - in older people, blood vessels become less strong and elastic, and adapt less well to pressure changes;
unhealthy diet, as well as frequent alcohol consumption;
atherosclerosis is a chronic metabolic disease in which plaques and blood clots (often cholesterol) form on the inner wall of the arteries.

Attacks of hypertension can be associated with stressful situations, in which blood pressure increases and the heartbeat accelerates. Thus, severe fear causes a sharp increase in blood pressure, accompanied by pain in the heart area. Symptoms also often occur during intense physical activity, especially at high temperatures and insufficient ventilation.

Symptoms of high blood pressure

More than 20% of people in the world suffer from chronic hypertension. The danger of this disease is that at the first stage it can be asymptomatic. The clinical picture is noticeable during the next attack, but during periods of remission the disease does not manifest itself in any way. When blood pressure increases, the patient experiences the following symptoms:

acute headache, dizziness;
nausea and vomiting, regardless of food intake;
acceleration of heart rate, manifestation of various types of arrhythmia;
redness of the skin in certain areas, often on the face;
the appearance of small subcutaneous hemorrhages - they are associated with rupture of capillaries from increased blood pressure and can also be found on the mucous membranes;
deterioration of hearing and vision, the appearance of black dots or circles in the field of vision;
fainting is possible.

The first symptoms of hypertension may remain unnoticed, but the load on the heart increases significantly. If you do not take this feature into account and continue to undergo intense physical activity, this can lead to dangerous consequences. A sharp increase in pressure is the main cause of vascular rupture and the development of hemorrhagic stroke with hemorrhage in the brain. Doctors at the Clinical Brain Institute recommend regularly measuring blood pressure at home, even if there are no prerequisites for this. This simple procedure will allow you to recognize hypertension in the early stages and prevent dangerous consequences.

Lower blood pressure

Hypotension (low blood pressure) is an equally dangerous disorder. With this disease, blood does not move through the vessels intensively enough and does not reach areas distant from the heart. Thus, the blood supply to the lower arms and legs, internal organs and brain may be disrupted. It is important to monitor your health and take prescribed medications, since low blood pressure can cause ischemic stroke.

Causes of hypotension

Hypotension is diagnosed if, as a result of several measurements, blood pressure readings are 90∕60 mm. rt. Art. and less. It can be a chronic disease of the cardiovascular system and can also occur in healthy individuals under certain conditions. So, the causes of hypotension can be:

deterioration of vascular tone, their constant expansion - the result of poisoning, allergic reactions and other disorders;
vegetative-vascular dystonia is a disease in which the regulation of vascular tone occurs, so their walls lose tone and elasticity;
dehydration of the body due to insufficient fluid intake, especially in the heat, in case of poisoning or during sports – leads to a decrease in the volume of circulating blood;
congenital and acquired diseases and heart defects, valve failure;
systemic use of certain medications, including drugs against hypertension, which lead to a persistent decrease in blood pressure.

Separately, physiological hypotension is distinguished - a decrease in blood pressure, which is within normal limits. Thus, indicators may be underestimated as a compensatory response to environmental conditions. Residents of high mountain regions experience a mild degree of chronic hypotension, which is not harmful to health. It also develops in athletes who regularly engage in intense physical activity. An increase in the mass and volume of the heart and an increase in the volume of circulating blood lead to the fact that for proper blood circulation in normal mode, a low blood pressure is sufficient. In some healthy people, blood pressure is constantly slightly reduced, and this is considered normal. In other cases, hypotension is a pathology and requires timely treatment.

Symptoms of low blood pressure

Hypotension can be asymptomatic only with a slight decrease in pressure. If the indicators are 90∕60 mm. rt. Art. and less, the clinical picture is clearly expressed. The disease manifests itself in attacks that sharply worsen health and can lead to fainting. The onset of an attack can be determined by the characteristic symptoms:

aching headache that can spread over the entire surface of the head or pulsate in the temples;
constant weakness, drowsiness, slow reaction to stimuli;
pallor of the skin and mucous membranes, with a sharp decrease in pressure to critical levels, their cyanosis may be observed;
decrease in skin temperature on the distal parts of the extremities (hands and feet) due to their insufficient blood supply;
nausea and vomiting;
tendency to faint when the ambient temperature rises, during physical exertion, while dieting, and in other cases.

If you often have a headache and feel sick, and your blood pressure is constantly below the normal limit, you should consult a doctor for a more complete diagnosis. Hypotension is dangerous to health, since the rate of blood circulation in this disease is significantly reduced. The main risk is insufficient oxygen and nutrients to the brain cells, which causes fainting. Ischemic areas form in the brain tissue, which cannot function fully. Persistent hypotension can lead to the development of ischemic stroke - an acute disorder of cerebral circulation. This condition poses a threat to the patient’s life, so it is important to take care to prevent its occurrence.

Other reasons

Nausea, weakness, high or low blood pressure, and headache are symptoms of a number of diseases caused by circulatory failure. They pose varying degrees of danger to the patient, but equally require full diagnosis and proper treatment. It is difficult to recognize the disease and make a correct diagnosis at home. In addition, many dangerous pathologies in the initial stages are disguised as ordinary malaise and fatigue.

Poisoning is a condition in which toxic substances enter the body or are formed as a result of metabolism. Food intoxication is the most common; poisoning with gases, alcohol and medications, and heavy metals is also identified. They are manifested by nausea and vomiting, decreased blood pressure due to dehydration, as well as acute headaches.
Heart defects can be congenital or acquired. They represent insufficiency of the heart valve apparatus. This leads to a deterioration in the movement of blood through the vessels, insufficient blood supply to internal organs, and an increased risk of myocardial infarction.
Atherosclerosis is a chronic metabolic disorder in which the walls of blood vessels become dense and inelastic. Plaques and blood clots form on their inner wall, preventing normal blood flow. Often the cause of atherosclerosis is a violation of cholesterol metabolism, and this element is deposited on the walls of blood vessels and in the internal organs.

Blood pressure, nausea, headache - these symptoms may indicate severe fatigue, nervous tension, and stress. They can also appear in a healthy person, especially during sudden changes in weather conditions. Also, this picture may be a sign of poor nutrition, a lack of certain vitamins and minerals in the diet.

Signs of food poisoning

Symptoms of poisoning are largely similar, regardless of the cause. They are distinguished by intensity and severity depending on the type of toxic substance, age (poisoning in an adult is easier than in children and the elderly) and the amount eaten. However, signs of an inflammatory process in the walls of the intestines and stomach, as well as manifestations of general intoxication of the body, almost always occur.

Signs of poisoning:

chills, diarrhea, nausea with vomiting;
feeling unwell, malaise, weakness;
bloating, painful cramping sensations;
rise in temperature (usually small).

Severe poisoning, for example, with botulinum toxin, is accompanied by symptoms of damage to the nervous system:

dry mouth and difficulty swallowing;
muscle weakness;
blurred vision, double vision;
loss of coordination of movements.

Diagnostic methods

If you feel sick and have a headache, it is important to determine what pressure the patient has. This can be done at home using a tonometer. The most informative results are in dynamics, so it is better to take several measurements with a short interval. The Clinical Institute of the Brain has all the conditions and modern equipment for full diagnostics. Experienced doctors will prescribe additional examinations that will make it possible to make an accurate diagnosis and establish the cause of poor health.

Blood tests are one of the first stages. Clinical analysis will help determine the level of hemoglobin, the number of red blood cells and other elements. Based on biochemical analysis, dysfunction of the heart and other organs can be suspected. Separately, the doctor can measure blood glucose levels and prescribe additional tests to determine the concentration of various vitamins and microelements.
Dopplerography is an examination of blood vessels using ultrasound using a contrast agent. More often, this technique is prescribed when a violation of cerebral blood flow is suspected. Ultrasound of the vessels of the head is informative if chronic cerebral ischemia, thrombosis, or aneurysms are suspected.
MRI, CT scan of the brain is the most accurate, informative diagnostic method for stroke, various brain tumors and other pathologies. Using a tomograph, you can get a complete three-dimensional picture and detect any disorders of the brain. The technique is complex and requires highly qualified specialists, but is available at the Clinical Brain Institute.

Pressure surges, nausea, headache - these signs may indicate a stroke. At home, you can carry out its initial diagnosis, but even if there is no positive response to the tests, it is recommended to consult a doctor. The patient should be asked to smile, raise both hands in front of him, and repeat a simple sentence. In this way, it is possible to determine disturbances in coordination of movements, facial expressions and speech, characteristic of damage to certain areas of the brain. Further treatment is carried out only in a hospital setting, aimed at restoring lost functions.

Weather dependence is called the sixth sense

First, let's dispel the doubts of skeptics. Weather sensitivity is not an invention of muslin young ladies. This has been confirmed by science: in people who are sensitive to weather changes, the level of leukocytes in the blood increases on such days. And medical statistics have recorded: more than 60% of city residents over 28 years of age react to bad weather. The proportions are as follows: there are one and a half times more representatives of the fairer sex who sense the approach of an atmospheric front than the stronger sex.

Young children are distinguished by the most subtle sensitivity. Mothers of infants notice that babies begin to cackle as soon as the weather changes.

Treatment methods

The treatment method for high or low blood pressure, nausea, and headache depends on the exact diagnosis. It is prescribed only based on diagnostic results and often involves taking specific medications. It is important to understand that independent selection of medications can aggravate the situation and lead to undesirable consequences.

Drug treatment is the main stage of therapy. The doctor selects medications to correct blood pressure for hyper- or hypotension and describes in detail the regimen for taking them. You may also need a course of vitamins, and for chronic hypertension, diuretics.
Diet is a necessary condition for high or low blood pressure, as well as for atherosclerosis. The patient needs to give up fried foods and sweets, limit the intake of salt and fast carbohydrates.
Work and rest schedule is one of the main points. It is important to ensure a good night's sleep and make time for light physical activity. These conditions will help stabilize blood pressure and improve the functioning of the cardiovascular system.

Clinically, the Brain Institute specializes in the diagnosis and treatment of disorders that are accompanied by headache, nausea, blood pressure, and general deterioration of well-being. Experienced specialists, modern equipment, highly qualified personnel are the main advantages of the center. Here you can undergo treatment in a hospital setting, under round-the-clock supervision by doctors, and also receive recommendations for maintaining health at home.

Manifestations of weather dependence

Patients with diseases of the bronchi and lungs, asthmatics, arthritis sufferers, and hypertensive patients can accurately predict bad weather. If the temperature outside the window and atmospheric pressure immediately decrease, they expect their condition to worsen, complaining of pain in the joints and stiffness in movement.

Cores can compete with the hydrometeorological center in the accuracy of forecasts. A couple of hours before the weather changes (and it could even be a change in the direction of the wind), they complain of headaches, weakness, anxiety, joint pain, and angina attacks. The hardest days for them are those with high air humidity and when a thunderstorm is approaching.

Heart crises, as ambulance workers note, occur at times of pronounced activity of the geomagnetic field and magnetic storms. A sick heart also reacts to periods of high sun activity.

The state of health these days deteriorates in those suffering from vegetative-vascular dysfunction (previously this disease was called vegetative-vascular dystonia), gastritis, patients with pneumonia, pyelonephritis, eczema. People with mental problems have another influencing factor - lunar tides.

In principle, any chronic responds to bad weather, doctors say.

How to reduce high blood pressure at home

High blood pressure is a very serious symptom. Therefore, any therapy should be prescribed strictly under supervision and on the recommendation of a specialist!

However, regular blood pressure medications should be in your home medicine cabinet, especially if there are real prerequisites.

If the increase in pressure is situational in nature and caused by emotional or nervous shock. First of all, you should balance your breathing, find ways to calm down and relax as much as possible. Among the medications you can use: sedatives of plant origin, for example: novo-passit, persen, valerian tab, motherwort extarct tablet and others.
To reduce blood pressure, diuretics can be used as part of complex therapy or as an independent remedy: Their selection and prescription, as well as the choice of dosage, is carried out by the doctor.
If hypertension is an established chronic disease and another attack occurs, it is important to take as quickly as possible: Emergency drug Captopril 25 mg sublingually 0.5-1 tablet, and consult a doctor as soon as possible.
