Nervousness, nervousness, difficulty sleeping
The temperament of people with high blood pressure is often impatient, very sensitive when it comes to things, easily excited. Anxiety, insomnia are common symptoms; Most people lose sleep because they have trouble falling asleep or wake up early, sleep restlessly, or have nightmares, or startle easily. This is associated with dysregulation of cortical function and ataxia of autonomic nervous function.
According to medical experts, hypertension, cardiovascular disease and insomnia are closely related. Because, blood pressure is the pressure of the blood in the vessel walls, affected by the force of contraction of the heart muscle. When awake, exercising, the heart and blood vessels have to work a lot to carry blood throughout the body systems and return blood to the heart, and when sleeping, the heart is more rested, other activities are less active. or rest.
Thus, if there is little sleep, lack of sleep, restless sleep or prolonged and frequent insomnia, the heart and vascular system must work more, so it is easy to cause disorders leading to hypertension, cardiovascular disease, if Pre-existing hypertension, cardiovascular disease, prolonged insomnia will aggravate the disease, even cause complications.
According to the Ministry of Health, high blood pressure can be effectively prevented through a healthy lifestyle. Specifically, people need to maintain a reasonable diet: less than 5g of salt a day, increase the intake of green vegetables and fresh fruits, limit foods high in cholesterol and saturated fatty acids, ensure enough potassium and trace elements. amount in the daily diet. At the same time maintain a reasonable weight, maintain a waist circumference less than 90 cm in men and less than 80 cm in women. Do not smoke or smoke, limit alcohol consumption. Increase physical activity, at least 30 minutes a day.
Slightly less common, because high blood pressure can lead to hardening of the arteries, making blood vessels less elastic and more brittle, so they are more likely to burst and bleed. In which nose bleeding is common, followed by conjunctival hemorrhage, fundus hemorrhage, brain hemorrhage. According to statistics, among patients with nosebleeds, about 80% have high blood pressure.
The heart rate increases, the cardiac output gradually increases. In the beginning, there is vasoconstriction to redistribute the blood circulating from the periphery to the heart and lungs, so the vascular resistance also increases gradually. The heart exhibits compensatory hyperactivity and leads to left ventricular hypertrophy. Blood pressure and total peripheral resistance gradually increased. Cardiac output and systolic flow decrease further, eventually leading to heart failure.
In hemodynamic changes, the arterial system is often completely damaged prematurely. Previously, it was thought that only the arterioles had vasoconstrictive changes resulting in increased peripheral resistance. It is now recognized that large vessels also have a hemodynamic role in hypertension. The lesser known function of the great arteries is to reduce the impulses and blood flow produced by the heart. Therefore, the parameter of arterial dilatation (compliance artérielle) is a good indicator of the capacity of the arteries. A decrease in this parameter indicates stiffness of the great arteries, which is a progression of arterial hypertension and in the long term increases cardiac work leading to left ventricular hypertrophy. At the same time, the increased pulse (hyperpulsatilité) of the arteries leads to damage to the bioelastic structures (bioelastomeres) of the arterial wall.
In the brain, blood flow remains balanced within certain limits during periods of marked hypertension. As blood pressure increases, peripheral resistance to increase plasma volume tends to decrease until renal failure, increasing blood volume can lead to edema.
Symptoms of the brain
In the early stages, the sympathetic effect manifests itself in an increase in heart rate and an increase in cardiac output. Sympathetic nervous system activity is also expressed in the amount of catecholamines in plasma and cerebrospinal fluid such as adrenaline, no-adrenaline, but these concentrations are also very variable in hypertension.
The sympathetic autonomic nervous system is controlled by the medulloblastoma and the two systems are interrelated through pressure receptors. In hypertension the baroreceptors are highly regulated and with the highest sensitivity threshold. High blood pressure is the most important risk factor for a stroke, which can cause a branch to rupture and lead to bleeding in the brain. Cerebrovascular accident, common such as cerebral embolism, cerebral hemorrhage, transient cerebrovascular accident with focal neurological symptoms lasting less than 24 hours, or hypertensive encephalopathy with confusion, coma followed by convulsions, vomiting, severe headache.
High blood pressure increases the risk of bleeding in the brain (stroke) 10 times. According to a study, even if your blood pressure is slightly high, you are still at risk of having a stroke. In fact, high blood pressure is the cause of 80% of heart attacks and strokes. High blood pressure weakens the small blood vessels in the brain causing them to burst. If the blood flow to the brain is interrupted, causing transient cerebral ischemia, dizziness, lightheadedness, severe may increase the risk of mild cognitive impairment, memory loss, rupture of cerebral blood vessels leading to paralysis, Brain hemorrhage can lead to coma and death.
When blood pressure increases too clinically (systolic blood pressure greater than 180-200 mmHg, depending on the case) will occur malignant hypertensive encephalopathy syndrome: severe headache, nausea, vomiting, weakness limbs, altered state of consciousness. If not treated promptly, the disease can progress more seriously, the patient will be lethargic, comatose, convulsive, even die within a few hours.
Unfocused attention, memory loss
These symptoms are usually not obvious in the early stages, but depending on the development of the disease, they gradually worsen. Because of these distressing deviations, it becomes one of the reasons that motivate patients to seek medical attention, manifesting as inattentive attention, poor memory, often difficult to remember recent events, but for Past stories like childhood, remember them very well.
High blood pressure impedes blood circulation to nourish the brain, so long-term memory impairment manifests as forgetfulness. Loss of concentration is one of the signs of memory loss. Common manifestations of distraction are: difficulty in receiving new information, impaired memory, disturbances in daily activities and gradual loss of the ability to remember at work.
Loss of concentration and memory will be very harmful to the brain and health if we do not care and deliberately prolong the disease. Therefore, when we see the symptoms of memory loss, we should go to the neurologist so that the doctor can directly examine, take pictures and do tests to find the cause of the disease and treat it promptly to prevent it. bad progression of the disease.
Symptoms of Kidneys
Severe or persistent high blood pressure can damage the blood vessels that supply blood, oxygen, and nutrients to the kidneys. When the blood supply to the kidneys is reduced, the kidneys cannot get rid of waste and excess fluid as they should. Conversely, when fluid in the body accumulates and is not excreted, it causes blood pressure to rise. Like that will create a vicious circle and directly affect each other.
As mentioned above, high blood pressure makes the heart work harder, putting pressure on the walls of blood vessels in the body, including blood vessels in the kidneys. Thereby, affecting the filtering function of the kidneys in eliminating waste products and excess fluid from the body. If this condition is repeated for a long time, it will cause chronic kidney disease. For people who already have kidney disease before developing high blood pressure, the kidneys will become progressively weaker. According to a study by the American Association of Kidney Patients, treating high blood pressure can slow the progression of kidney disease.
When the kidney’s filtering function is impaired due to the effects of high blood pressure, protein can leak into the patient’s urine. If large amounts of protein are lost through the urine, the level of protein in the blood (also known as albumin) will drop drastically, leading to a serious condition known as nephrotic syndrome. When this happens, the body will retain water retention, causing swollen legs, fatigue and loss of appetite. Sometimes blood clots can form in the calves and lungs, which can be fatal if not detected early.
One of the most dangerous complications of high blood pressure is kidney failure. At this time, many cases require hemodialysis or a kidney transplant to maintain life.
Numbness in hands and feet
Often numbness in fingers, toes or skin that feels like crawling, or, tight, aching back muscles. Some patients often feel that their fingers are not flexible. Usually, with proper treatment, the condition can get better. But if the limbs are numb and stiff, lasting for a long time, moreover only appearing in a fixed limb, and accompanied by weak limbs, tendons, when jumping, it hurts, you must promptly go to the hospital for examination. and treatment to prevent leprosy (cerebrovascular accident).
People with high blood pressure can cause numbness in the limbs. When blood pressure suddenly increases, the small arteries in the body twitch, the ductus arteriosus will become small, the blood flow to the extremities is also affected, causing numbness. Numbness in the limbs, accompanied by dizziness, it is necessary to check blood pressure, normally use medicine as directed by the doctor to control blood pressure. When blood pressure is unstable, it is necessary to rest, do not exercise vigorously and keep a stable mood. Daily, can use chrysanthemum, flower, green tea, 3g each, mixed with boiling water to drink instead of tea, this method can help control blood pressure.
Numbness in the limbs is the most common of neurological and vascular diseases. The disease has many other names such as numbness of hands and feet, numbness of hands and feet, numbness of limbs, or numbness of hands and feet. Numbness in the limbs often appears in many subjects with different ages and affects the life, work and activities of the patient. Not only that, if numbness of hands and feet is not treated in time, the disease can progress more seriously and cause many dangerous and unpredictable consequences.
Headache is the most common symptom of high blood pressure, there are some cases of sudden onset, often appearing when suddenly stooping, sitting down or standing up; There are also some cases of continuity. Headache is the main suffering of patients, their head has a constant uncomfortable feeling of heaviness, seriously interferes with thinking, affects work, loses interest in activities. surrounding objects.
Certain medical conditions that occur when blood pressure is high, such as heart disease, can make you feel dizzy. In addition, patients who have had a stroke due to high blood pressure will also have symptoms of dizziness.
As can be seen, the main association between dizziness and blood pressure is that uncontrolled blood pressure leads to dizziness along with other symptoms. Only a small number of cases of dizziness are caused by high or low blood pressure, while the majority are caused by other causes. Often cases involving dizziness and blood pressure are few and resolve quickly.
Symptoms of high blood pressure affecting the eyes
High blood pressure can cause blood vessels to burst and bleed in the eye, which can cause blurred vision or permanent blindness. Blood in the eye or conjunctival hemorrhage can be a sign of diabetes or high blood pressure. The appearance of blood stains in the eyes is rarely detected early, because the eyes are the position we often ignore when looking in the mirror, it is difficult to detect the tiny blood stains in the eyes because they are often confused with the blood rays in the eyes. .
Usually, when a patient has eye problems, a doctor can detect damage in the eye. Therefore, everyone, especially the elderly, should make a habit of observing themselves in detail every day, to recognize even the smallest changes in the body to take appropriate prevention and treatment measures. well suited.
Prolonged, or sudden, high blood pressure will damage the vascular system in the retina, block the central vein of the retina, aneurysm in the retina… more severe can cause rupture or rupture blood vessels in this area. When blood vessels are broken, fluid escapes, causing crystalline hemorrhage (transparent vitreous layer, accounting for 2/3 of the volume of the eyeball), retinal edema. Not only that, if the blood vessels are constricted (atrophy), there will be ischemia in the retina, atrophy of the optic nerve, retinal detachment … all these complications if not treated early are possible. can lead to blindness.
At first, when there are complications on the eyes, the patient often has no obvious symptoms, so it is difficult to detect until the vision test, ophthalmoscopy, etc. Blood pressure rises too high (usually above 200/140mmHg), causing sudden onset of symptoms such as headache, photophobia, blurred vision, even eye pain. Therefore, for people with a history of high blood pressure when experiencing the above symptoms, it is necessary to go to the doctor and have their vision checked immediately for timely treatment.
Headache is also a common symptom of high blood pressure, most often it is a constant dull headache, or intermittent pain, even severe pain like tearing. Usually occurs when waking up early in the morning, and then gradually decreases after waking up to activity and after meals. Most of the pain occurs in the temples on both sides of the forehead and at the back of the head.
Headache is a common phenomenon with high blood pressure. High blood pressure increases the constant pressure of the blood flow on the vessel wall, causing the vessel wall to gradually dilate and appear lesions. These lesions appear increasingly in the small blood vessels in the brain, causing tension headaches, this is an early sign of a stroke caused by high blood pressure. It is worth noting that the phenomenon of headache caused by hypertension is very easy to confuse with headache due to other causes. In this article, we would like to share with you how to distinguish a headache caused by high blood pressure and how to handle it when this phenomenon occurs.
The reason for the headache that often occurs when high blood pressure is high blood pressure increases the constant pressure of the blood flow on the vessel wall, causing the vessel wall to gradually dilate and appear lesions. These lesions appear increasingly in the small blood vessels in the brain, causing tension headaches, this is an early sign of a stroke caused by high blood pressure.
In severe cases, the sudden increase in blood pressure causes severe headaches (as seen in malignant hypertension) that can cause blood vessels to burst, causing cerebral hemorrhage. If the damage is small, the platelet system and fibrin fibers will come to repair the wound and form blood clots, blocking the blood vessels. The rupture or occlusion of the cerebral blood vessels all stop the blood supply, causing ischemia in the brain, leading to the appearance of clinical symptoms, such as headache, dizziness, dizziness, severe pain in the ears. Cerebrovascular changes manifest as mouth distortion, coma, hemiplegia can lead to death.
