My head is spinning because my blood pressure temporarily drops. When a person stands up abruptly, blood rushes to the legs, the heart rate and pulse increase, and the blood vessels constrict so that the pressure does not drop even more.
If the pressure returns to normal quickly, the person does not lose consciousness and orientation in space. Sometimes the vessels remain dilated after a certain period of time, then there is a risk of dizziness, since the blood flow to the brain is not strong enough.
There are also more serious causes of this disease associated with various diseases.
Main reasons
The main reason why your eyes get dark and you feel dizzy when you suddenly stand up is the lack of oxygen in the tissues and organs. This condition is known as anoxia (hypoxia). Oxygen deficiency causes orthostatic hypotension, which develops in cardiac pathologies. The reasons for its occurrence lie in the peculiarities of the circulatory system. If your eyes darken when you suddenly get out of bed, this indicates a decrease in blood pressure. A similar problem arises under the influence of cardiac pathologies. Orthostatic hypotension develops against the background of the following factors:
- heart defects;
- insufficient blood ejection from the heart;
- heart rhythm disturbance;
- active peripheral vasolidation, due to which insufficient blood flows to the brain.
Orthostatic hypotension manifests itself in a sharp drop (sometimes to zero) in blood pressure when changing from a horizontal to a vertical position. It is at this moment that your vision suddenly becomes dark and you feel dizzy almost immediately. Both signs are characteristic of a presyncope (lipotomy). At the same time, the patient experiences the following phenomena:
- general weakness;
- noise in the ears and head;
- increased sweating;
- paleness of the skin;
- leg incontinence;
- heaviness in the head;
- loss in time and space.
Lipotomy lasts for 3-4 seconds. In more severe cases, this condition is accompanied by a short-term loss of consciousness. Prolonged dizziness and other symptoms of lipotomy are accompanied by mild psychosensory disorders.
How to know if you are in danger
If you feel dizzy when you get up from your squat while following a strict diet, then the only culprit is a lack of glucose in the blood. If you received a scolding from your superiors or spoke in front of a large audience, then the symptom described that arose as a consequence should not be frightening either - in this case it is the result of a large release of adrenaline, which provoked vasospasm.
But if, after suffering from otitis media, you experience severe dizziness with cold sweat, nausea and vomiting, or your hearing decreases, and whistling or noise appears in your ears, then you should immediately consult a doctor.
The same actions must be taken if, along with dizziness, severe headaches are observed, accompanied by photophobia, nausea and tinnitus. And if the patient also has impaired coordination, vision and sensitivity, then reluctance to see a doctor can cause serious consequences.
It is not difficult to understand whether you need to go to a specialist. Remember that any additional symptoms are a reason to be wary!
How to identify orthostatic hypotension
It was stated above that the reason why your eyes get dark when you get up is a decrease in blood pressure. If this symptom occurs frequently enough, orthostatic hypotension may be suspected. This condition can be diagnosed through a special test. You can check for orthostatic hypotension by repeatedly checking your pulse while lying down and standing. It is important to achieve sustainable performance. Next, the pulse is checked when changing from a horizontal to a vertical position every 1, 3, 5 and 10 minutes. A deviation of 11 beats per minute is considered normal. The absence of orthostatic hypotension is also diagnosed when the blood pulsation exceeds normal values by 12-18 beats. If there are more strokes, medical attention is needed.
Other causes of darkening of the eyes
In a healthy body, internal systems themselves redistribute the direction of blood at the moment when a person changes a horizontal position to a vertical one. This phenomenon is called a reflex reaction. In a healthy body this process occurs quickly. Changes in blood pressure and pulse are insignificant. The course of cardiovascular pathologies and some other processes causes disruption in the functioning of the circulatory system. As a result, the body reacts late to changes in body position. This explains why, when you get up, your vision becomes dark. Changes in blood pressure occur under the influence of the following factors:
- psycho-emotional tension, constant stress;
- great physical activity;
- increased level of hemoglobin in the blood;
- deficiency of vitamins and nutrients;
- diseases of the endocrine system (diabetes mellitus and others);
- pregnancy.
People who have been taking certain medications for a long time often go to the doctor with complaints about dark vision and dizziness when I get up:
- vasodilators;
- diuretics;
- antidepressants.
Relatively often, the vision darkens when climbing in people who abuse alcoholic beverages and drugs. Such addictions negatively affect the functioning of the cardiovascular system.
A sharp drop in blood pressure causes darkening of the eyes when standing up. This phenomenon is also accompanied by the following symptoms:
- weakness in the body;
- scattered and unstable attention;
- dyspnea;
- memory loss.
It is important to pay attention to these symptoms promptly. If, with a sharp change in position, your vision becomes dim and everything around you begins to spin, a person, first of all, needs peace. In cases where these phenomena recur frequently, it is recommended to consult a doctor.
Dizziness when standing up: causes and solutions

Dizziness, stars in the eyes, loss of balance - why does one or more of these symptoms occur when getting up from your seat or getting out of bed? Often, if it stops within a few seconds, there is no need to worry.
"The heart is a pump, and when you suddenly stand up, the amount of blood going to the heart decreases," explained Dr. Phillip Low, a professor of neurology at the Mayo Clinic in Minnesota. “This can lead to a temporary decrease in blood pressure, and it takes a short period of time for the corrective mechanisms to correct this.”
In medicine, this condition is called orthostatic hypotension - a decrease in blood pressure until it normalizes. If you experience this occasionally, there may be a specific, easily correctable cause to blame.
For example, you haven't eaten or drunk enough water. Skipping meals causes your blood sugar levels to drop, which in turn causes dehydration and slows your circulation. Other causes of this include exercise, heatstroke, pregnancy, alcohol consumption and lack of sleep.
In the event that attacks of dizziness occur frequently and do not subside, i.e. If your dizziness does get worse the longer you stand, you should see a doctor.
"This means that blood pressure has dropped and is not recovering," said Dr. Christopher Gibbons, an associate professor of neurology at Harvard Medical School.
Orthostatic hypotension becomes more common with age, with 5-10% of people developing it by age 60. This condition increases the risk of falls and broken bones among middle-aged people, according to research.
If you feel like the room is spinning or spinning, it may be due to a problem in your inner ear known as vertigo (vestibular vertigo). It can be caused by ear infections or head injuries and requires medical attention.
And another sign of the seriousness of the situation is losing consciousness, even for a few seconds, after you get up. This requires a medical examination to identify a potential disorder related to the heart, nervous system, or endocrine system.
In addition, many patients take medications that directly lower blood pressure, either on their own or as a side effect. In such cases, you should consult your doctor, who will change the dosage or suggest an alternative. Never stop taking medications without your doctor's knowledge, as this may cause serious complications.
Darkening of the eyes during pregnancy
Very often, pregnant women are faced with the question of why it gets dark before their eyes when they get up. Orthostatic hypotension in women during pregnancy develops due to an increase in blood volume in the body. Because of this, the pregnant woman’s blood vessels and heart do not have time to adapt to the changes that have occurred. As a result, a change in body position leads to an attack of dizziness and short-term decreased vision. The symptoms of orthostatic hypotension are especially pronounced in women with vegetative-vascular dystonia. There is no specific treatment for this problem in pregnant women. It is important during the period of bearing a child to avoid sudden body movements and follow a daily and nutritional regimen.
Dizziness is a common occurrence in teenagers
As it turned out, most often with the question “why do you feel dizzy when you get up?” Teenagers turn to specialists. The fact is that this problem is caused by insufficient blood flow to the brain, associated with the lag in the development of the circulatory system at this age from the needs of a rapidly growing organism.
Teenagers are asked not to make sudden movements, but if necessary, sit for a while and then rise slowly. It is also important to regularly do exercises to strengthen the vestibular system.
If this happens occasionally, you don't have to worry. When your vision becomes darker when you change your body position more and more often, you need to consult a therapist to find out the cause.
What to do
Those who often neglect to adhere to the drinking regime need to ensure that a sufficient amount of fluid enters the body, and those suffering from anemia should undergo a course of treatment and adjust their diet.
If your vision gets dark and you feel dizzy, this may indicate some kind of illness. Each of these diseases has its own symptoms:
- migraine. In addition to dizziness, nausea and headache appear;
- otitis. Dizziness appears as an additional symptom;
- osteochondrosis. Dizziness and darkening of the eyes occur from sudden movements;
- oncology. All the symptoms that cause dizziness are present;
- head injuries. They cause a “whirlwind” in the head and blurred vision.
But special attention should be paid to the disorder, which most often causes darkness in the eyes and dizziness. This refers to vegetative-vascular dystonia.
This disease causes an imbalance in the functioning of the body. Usually it is always in a latent state and manifests itself as severe dizziness with darkening. It is impossible to diagnose dystonia on your own. Special methods are required.
Treatment of VSD is complex, which consists of drug therapy and a specific regimen. If the disease is not severe, you can limit yourself to the following methods:
- neck massage,
- acupuncture,
- hydromassage,
- healing baths.
As it turned out, most often with the question “why do you feel dizzy when you get up?” Teenagers turn to specialists. The fact is that this problem is caused by insufficient blood flow to the brain, associated with the lag in the development of the circulatory system at this age from the needs of a rapidly growing organism.
As a rule, orthostatic hypotension in young people from 13 to 20 years of age is perceived by doctors as a normal condition that passes as they grow older and undergo a complete restructuring of the body and only requires compliance with certain rules.
Teenagers are asked not to make sudden movements, but if necessary, sit for a while and then rise slowly. It is also important to regularly do exercises to strengthen the vestibular system.
Ways to solve the problem
tea
Taking medications for dark eyes
You can quickly solve the problem and tone up the body with a cup of strong tea with sugar. The drink restores blood flow, thereby ensuring normal nutrition of tissues and the central nervous system. A person experiencing dizziness must be placed in a horizontal position with his legs raised up. Otherwise, he should sit down and rest his head on his knees. Medicines to restore blood pressure are prescribed by a doctor after diagnosing the patient and establishing the true cause of the problem. Treatment of infectious pathology that causes cardiac arrhythmia is carried out with antibiotics. To compensate for iron deficiency, medications are prescribed that contain the missing component. Restoration of the nervous system is carried out using physiotherapy and peptide drugs. If your eyes become cloudy, rest for 30 minutes is recommended. At this moment, you should not drive or work with traumatic objects and equipment. To prevent the problem, regular walks and vitamin complexes are suitable.
