Is there a decrease in blood pressure due to hypertension? A rapid decrease in blood levels in hypertensive patients indicates severe disorders in the cardiovascular system. However, its decrease can also be provoked by external factors, such as the incorrect use of antihypertensive medications, and certain life preferences.
Let's look at what exactly provokes an excessive drop in blood pressure in people with hypertension, and how to behave in this situation in order to avoid extremely life-threatening complications.
What happens to the body when blood pressure drops sharply?
In case of hypertensive disease, low blood pressure is considered to be 100/60 mmHg. Art. Therefore, you should always check your blood level if suspicious symptoms occur, and only then take medications.
If there is a dramatic decrease in blood pressure, do not panic ahead of time, since there are certain blood pressure standards for hypertensive patients.
| Stage of hypertension | Blood pressure norms (mm Hg) |
| Lightweight | From 140/90 to 159/99 |
| Average | From 160/100 to 179/109 |
| Heavy | Above 180/110 |
A sharp decrease in blood pressure in a hypertensive patient is a rather dangerous situation for the body, especially with severe vasoconstriction or a few days after a stroke. High pressure (from 140/90 or an individual value) after it indicates the normal functioning of cerebral circulation, thereby preventing its hypoxia.
With a significant drop in blood levels, mechanisms for its increase are necessarily triggered, which can provoke the manifestation of a hypertensive crisis. The older a person is with a problematic cardiovascular system, the higher the likelihood of developing it.
It is for this reason that during an acute attack, doctors do not allow blood pressure to be greatly reduced with medication, which can contribute to the rapid development of a stroke. Failure to comply with medical recommendations is dangerous in the following ways:
- With strong dilatation of the arteries, the amount of circulating blood does not increase; the body simply does not have time to increase its volume.
- Due to the sharp increase in the lumen in the brain area, their rapid narrowing is observed.
- Due to improper blood flow in the brain, there is a lack of oxygen supply to the brain tissue, which leads to hypoxia and hemorrhage.
- If hemorrhage develops, the chance of saving the patient’s life is zero.
Clinical manifestations
As a rule, without checking blood pressure with a tonometer, the patient believes that he has had another jump in pressure and makes a fatal mistake - he repeatedly takes antihypertensive pills, which leads to an additional decrease in blood levels. Hypotension and hypertension have common symptoms, so you should pay more attention to their manifestations.
Characteristic signs indicating abnormally low blood pressure in hypertension:
- Extremely pale skin.
- Darkening in the eyes.
- Tinnitus and hearing loss.
- Severe weakness.
- Chills.
- Dizziness.
- Manifestation of chills.
- Cold hands and feet.
- Recession of veins.
- Cold and clammy sweat.
- Blue discoloration of the lips and nasolabial area.
- The gait becomes unsteady.
- Severe numbness in fingers and toes.
- The patient begins to talk and does not recognize his relatives.
- Loss of perception of the surrounding world and coordination in time.
It is also worth emphasizing this important nuance: with extremely low pressure, the general clinical condition of a hypertensive patient resembles signs of severe alcohol intoxication. Therefore, many people, because of their similarity, often refuse to help the patient, believing that he simply drank too much.
What to do to stabilize the condition?
Low blood pressure in hypertensive patients can be controlled with medications. The basis of the prescribed course of treatment by the doctor is a healthy lifestyle and the following medications:
- Adrenergic and sympathomimetics. Medicines have a uniform vasoconstrictor effect and increase blood pressure. Do not affect heart rate (Midodrine, Norepinephrine).
- Anticholinergics. Their action is aimed at blocking receptors and acetylcholine (Belloid).
- Adaptogens. Restore normal activity of the cardiovascular system.
- Stimulants. Their action is aimed at the central nervous system, relieving fatigue and drowsiness.
Alternative medicine
To improve your condition, a person can drink strong brewed coffee.
To raise blood pressure, it is recommended to drink a cup of strong tea or coffee. Unfortunately, this method will not be effective if a person drinks such drinks every day. You can add honey and cinnamon to your diet; they will help normalize the patient’s condition. In addition, to increase blood pressure, herbal infusions are used:
- Equal proportions of viburnum leaves, chokeberry and lingonberry are poured with boiling water. You need to insist for 2 days in a dark place. Then take it for 3 days, but before each dose you must always measure your blood pressure.
- Combine beet, carrot and rare juice in equal proportions. Add honey and take 2 tablespoons 3 times a day before meals.
- A decoction of St. John's wort will help relieve the feeling of fatigue and give strength.
Heart attack or stroke accounts for 70% of all deaths. Therefore, it is important to understand that low blood pressure against the background of hypertension indicates serious disorders, and attempts to correct the situation by taking medications on your own will only worsen the situation, so consultation with a doctor is necessary.
Reasons for low blood pressure in hypertensive patients
So, why does hypotension suddenly occur when blood levels are high, and what do doctors say about this? The reasons for the decrease in blood pressure in hypertensive people can be varied, so it is worth analyzing the clinical situation and establishing what exactly led to the decrease in blood pressure. In any case, the body tells you that something bad is happening to it and it is necessary to begin treatment immediately.
Factors leading to an excessive decrease in blood pressure in hypertension may be:
- Pathological origin.
- Non-pathological.
Let's take a closer look at the circumstances that can cause a drop in blood levels due to hypertension.
Reasons for decreased blood pressure due to illness
A sharp decrease in blood pressure in a hypertensive patient can cause some chronic diseases, including those of the cardiovascular system.
| What causes a sudden drop in blood pressure? | How do they affect blood pressure levels? |
| Heart failure | Manifests itself due to inflammatory processes, for example, myocarditis or endocarditis. There is a slowdown in heart rate, it is more difficult for the heart to cope with its functions, the speed of blood circulation slows down, and as a result, blood pressure decreases. |
| Vegetovascular dystonia | In case of emotional or mental stress, the functioning of the central nervous system is disrupted, which leads to hypotension. |
| Anaphylactic juice | The presence of both of these factors contributes to a sharp decrease in arterial levels. |
| Low presence of glucose in the blood during the development of diabetes | |
| Edema of lung tissue | It not only contributes to the manifestation of hypotension, but also provokes cough, tachycardia, pain in the chest, and increased heart rate. |
| Pathologies of the kidneys and adrenal glands | The adrenal glands produce important hormonal substances for the body, such as acetylcholine and adrenaline, which maintain vascular tone at the proper level. Adrenaline can increase blood pressure, and acetylcholine, on the contrary, reduces blood pressure. In case of failure of the working functions of the kidneys and adrenal glands, acute surges in blood pressure are observed. |
| Infectious diseases | High body temperature and intoxication of the body also contribute to the manifestation of hypotension. |
| Depression | The manifestation of severe depression often leads to a drop in blood pressure. |
| Bleeding | Heavy blood loss (not less than 800 ml) of any etiology always causes a drop in blood levels. |
Non-pathological causes of low blood pressure
Among the external provoking factors leading to an excessive drop in pressure are:
- Prolonged bed rest.
- Elderly age.
- Physical inactivity (sedentary lifestyle).
- A sudden change in position (for example, from lying to sitting).
- Poor nutrition (eating foods that are harmful to hypertensive patients).
- Alcohol abuse and smoking.
- Prolonged exposure to the scorching sun provokes the formation of certain substances, which, when released into the blood, lead to a rapid drop in blood pressure.
- Incorrect medication intake.
- Overdose of antihypertensive medications.
In addition, the illiterate use of drugs that can conflict with medications for hypertension and cause severe relaxation and vasodilation (antispasmodics, sedatives, cardiac drugs, antibiotics, painkillers and beta-blockers) leads to a rapid decrease in blood pressure
Factors that provoke a decrease in blood pressure can be of different nature, so it is difficult for a person to independently determine the true cause of a decrease in blood pressure during hypertension. Only a cardiologist can help determine what exactly led to this condition.
Hypertension

The diagnosis of “hypertension” (also known as arterial hypertension, arterial hypertension and essential hypertension) is made to the patient if his blood pressure is higher than 140/80.
After making a diagnosis, it is very important to get checked by an endocrinologist, and first of all, determine the levels of glucose and insulin in the blood, since their increase is very often the main cause of high blood pressure.
People with type 2 diabetes are often obese, which is another risk factor for cardiovascular disease, so hypertension and insulin resistance are quite closely related.
A patient suffering from both diseases is prescribed a diet that helps lower blood sugar levels and also lose weight. To do this, you should completely eliminate or significantly reduce the consumption of foods containing sugars and starches, that is, baked goods, pasta, rice, cereals, and potatoes. It is also advisable to limit fruits somewhat, but not completely exclude them, since they are an important source of vitamin C, which is necessary for hypertensive patients.
Old and proven advice to all those suffering from cardiovascular diseases is to regularly eat citrus fruits.
It is important to ensure that the level of fructose consumed is no more than 25 grams per day. For reference : one average orange contains 6 g of fructose, banana - 7, peach - 6, apple - 9.5, pear - 12.
The fact is that one of the breakdown products of fructose is uric acid, the accumulation of which leads to several disorders, including hypertension.
Of course, if you have high blood pressure, you should give up alcohol and smoking - however, these two factors are unnecessary for any ill health.
With hypertension, it is very important to pay attention to whether the pressure decreases at night. If it remains elevated early in the morning, you should definitely check your heart as well as your vitamin D levels. The best way to optimize your body's vitamin D levels is to get regular sun exposure, but if you can't avoid taking extra vitamin D, choose a product that contains the active ingredient. its form is vitamin D3 (not D2).
An excellent source of vitamin D is fish oil. By taking it, you simultaneously replenish your body with omega-3 fatty acids, which, as scientific research shows, also have a cardioprotective effect.
Many experts recommend a salt-free diet for hypertensive patients, especially those whose hypertension is associated with kidney disease (and this is a very common combination of diseases). This issue, however, should be approached carefully and individually.

On the one hand, salt actually increases blood pressure, on the other hand, a lack of the main source of sodium can lead to an imbalance in the sodium balance in the body, which often causes a decrease in insulin production and leads to cardiovascular diseases. Therefore, the decision to limit salt should be made taking into account the patient's comorbidities. If such a decision is nevertheless made, hard cheeses, milk, beef, eggs, and rye bread will help replenish sodium in the body.
It's no secret that high blood pressure is often a consequence of stress, especially in middle-aged and elderly people. Advice to avoid troubles would sound strange, because they happen regardless of our will. It is useful, however, to master one or another technique of emotional control. There are many of them, and anyone who sets such a goal will be able to find something that is right for him to maintain peace of mind.
An important part of the prevention and treatment of arterial hypertension is physical exercise. An exercise program for hypertensive patients should include not only aerobic exercise (with a pulse range of 140-160 beats per minute), but also anaerobic exercise (with a pulse range of 160-180 beats per minute), which largely contribute to improving the functioning of the heart and lungs, and reduce risk of cardiovascular diseases.
This includes fast sprints, jumping rope, weight training, climbing steep hills, and any activity that involves heavy loads.
Under no circumstances should you immediately start intense exercise, as this can lead to the exact opposite result. It is best to start with fast walking, jogging, cycling, swimming.
Why is low blood pressure dangerous for hypertensive patients?
If a hypertensive patient's blood pressure drops, what consequences might this have? Doctors emphasize that in such a clinic the following is observed:
- The blood vessels and heart experience excessive tension.
- The arteries begin to expand greatly, which is very dangerous for the cardiovascular structure.
- The heart and lungs experience excessive oxygen starvation.
- The risk of ischemia, stroke and heart attack increases several times, especially for older people.
- There is a high risk of fainting, which increases the likelihood of injury during a fall.
- The work of cerebral circulation is disrupted.
- A rapid drop in blood pressure can cause cardiac arrest.
- In the presence of hypertension in pregnant women, a clear manifestation of hypotension is fraught with the development of intrauterine pathologies of the fetus or miscarriage.
- When using the wrong dosage of medications for hypertension, when the pressure drops quickly, there is a severe disruption of the basic working functions of the blood circulation, which can lead to a stroke.
A rapid and unexpected decrease in blood pressure in patients with hypertension can lead to loss of consciousness and ischemia. The patient becomes so accustomed to his illness that he perceives any manifestations of hypotension as another increase in blood pressure, not thinking that the arterial level may not rise, but, on the contrary, drop to critical levels.
Safe pressure
Blood pressure is the force with which blood pushes against blood vessels. The phrase “blood pressure” is used to mean pressure in all vessels of the body, although pressure can be venous, capillary and cardiac. Indicators of 120/80 mm Hg are considered safe for human life. Art. The maximum permissible limit pressure is up to 140/90 mm Hg. Art. If the indicators rise even higher, this indicates a tendency towards hypertension. The largest number, the first, is the systolic blood pressure indicator, this is the critical pressure when the heart is at its peak degree of compression. The second number is the diastolic indicator - at the moment of relaxation of the heart. They are called “upper” and “lower” respectively.
But you shouldn’t constantly check the standards, because each organism is individual. For one, the norm is 80/40, and for others, 140/90. But even if a person does not have any unpleasant symptoms with non-standard blood pressure readings, this is not a reason to be careless about health and not pay attention to it. Consultation with a doctor is necessary even in this case.
Basic rules for providing primary care for a rapid decrease in blood pressure
What to do if a hypertensive person’s blood pressure drops sharply? In this situation, call an ambulance and take the following actions before it arrives:
- If you feel a sudden deterioration in your health, indicating a decrease in blood pressure, you need to warn your loved ones or people around you about this. Don't be shy about strangers - they will help save your life.
- If the pressure drops low while the hypertensive patient is outside, you need to move him to a shaded place, away from direct sunlight.
- If the pressure is rapidly decreasing, it is necessary to measure its level. If your blood pressure suddenly drops to 100/60 and you feel unwell, you need to lie down and raise your legs slightly, which helps improve the flow of blood fluid to the head and upper body.
- You should unbutton your collar and outerwear, remove your tie, belt - anything that interferes with the free flow of air into the respiratory system.
- If you lose consciousness, an ear massage will help bring you back to your senses.
- If vomiting occurs, the patient should be placed on his side.
- If chills occur, cover the person with a blanket.
- You can massage the head, back of the head and neck, which will significantly improve the well-being of the victim.
- Before the ambulance arrives, eat a piece of dark chocolate or drink strong black tea. Among the medications, you can take Citramon or another caffeine-containing drug.
Experts recommend paying attention to actions that are prohibited from being performed in such a situation:
- Bring a cotton swab with ammonia to the victim’s nose.
- Bring to life through any alcoholic and low-alcohol drinks.
- Spray your face with ice water.
- Use heart medications with an alcohol component.
- If the blood pressure of a hypertensive patient suddenly drops, you cannot independently take different medications one after another to regulate blood pressure. One medication will be enough until the ambulance arrives.
- Only a specialist can recommend the optimal medicine after the cause of the decrease in blood pressure has been established.
At what pressure can a person die?
Death can occur both with too low and very high blood pressure.
Hypertension
A pressure above 180 to 110 millimeters of mercury is called fatal. Dystrophic transformations begin in the myocardium, the walls of blood vessels thicken, lose elasticity, vision drops sharply, and blood supply to tissues is disrupted. Without medical care, the patient has very little chance of survival.
Hypotension
Lethal indicators for humans are below 45 millimeters of mercury. The patient loses consciousness and cardiogenic shock develops. Peripheral blood circulation is disrupted, oxygen does not reach the brain and internal organs.
If blood pressure readings change sharply in one direction or another, the patient may die from:
- heart attack;
- stroke;
- intravascular coagulation;
- cerebral or pulmonary edema.
Doctors consider pressure changes to be the most dangerous: from low to high and vice versa.
Preventive measures
If a hypertensive person takes a responsible approach to his health and carefully follows all the necessary measures to prevent an unexpected decrease in blood pressure, then the risk of developing such a situation is significantly reduced.
You should listen to the advice of cardiologists:
| Factors | What do we have to do |
| Nutrition | Drink the required amount of fluid (at least 2 liters per day). Eat right, giving preference to healthy foods. Limit salt intake. |
| Schedule | Adjust your daily routine, clearly allocating time for work and rest. An important condition to follow is to be sure to go to bed and get up at the same time. After waking up, you should not immediately get out of bed. It is necessary to lie down for several minutes, allowing the body to bring blood pressure back to normal after a night's rest. |
| Physical activity | Regularly engage in feasible physical activity. A sedentary lifestyle does not have a very good effect on the condition of blood vessels. Walk in the fresh air as often as possible. Do morning exercises and other gymnastic exercises. |
| Emotional condition | Try to avoid stressful situations and mental stress, especially in old age. Emotional stress is a common cause of a strong drop in blood pressure. |
| Well-being control | After taking an antihypertensive medication, you should constantly monitor your well-being. If any abnormalities are observed, consult a cardiologist. Carry out regular monitoring of blood pressure, and record the results of the tonometer in a notebook. |
| Water treatments | Hypertensive patients are prohibited from using a contrast shower at home in order to increase muscle and vascular tone and taking a steam bath. Pool access, group water activities and swimming are permitted. |
Why does blood pressure drop?
Causes of low blood pressure.
Causes of low blood pressure:
- The first and main thing is the bad effects of stress and emotional overload.
- Strong mental load.
- Working in harsh conditions is also dangerous. These conditions include working underground, in high humidity or in extreme temperatures.
- A decrease in blood pressure is caused by diseases of the central nervous system, cardiovascular system, adrenal glands, and thyroid gland.
- Sedentary lifestyle.
Hypotension occurs in athletes, even though they do not lead a sedentary lifestyle. It occurs as a defense for the body during frequent physical activity.
