why do i feel dizzy when i get up

Understanding Dizziness When Standing Up

Feeling dizzy when you stand up is a symptom many people experience. This often occurs when you suddenly get up or stand up from a sitting or lying down position. Dizziness, especially lightheadedness upon standing, happens because blood flow to the brain is temporarily insufficient. It can occur when your body’s adjustment to a new posture, specifically blood pressure and blood flow regulation, doesn’t work smoothly. While often temporary, it’s important to pay attention if it happens repeatedly or is accompanied by other symptoms. There are various causes, ranging from simple physical discomfort to potential signs of an underlying illness. It is important to correctly understand this symptom and take appropriate action.

What Causes Dizziness When Standing Up?

The causes of dizziness upon standing up are diverse. In many cases, it’s due to a temporary glitch in the body’s physiological adjustment mechanisms, but it can also hide an underlying disease. To identify the cause, it’s crucial to carefully observe the circumstances under which the dizziness occurs and any other symptoms that appear simultaneously. Here are some of the common causes known. The nature of the dizziness, accompanying symptoms, and appropriate treatments vary depending on the specific cause.

orthostatic hypotension and blood pressure drops

One of the most common causes of dizziness when standing up is orthostatic hypotension. This happens when your blood pressure drops sharply when you stand up from a lying down or sitting position. Normally, when you stand up, gravity causes blood flow to shift to the lower body, temporarily reducing the blood flow returning to the heart. In a healthy body, the heart beats faster and blood vessels constrict to maintain blood pressure and ensure blood flow to the brain. However, with orthostatic hypotension, this regulatory function doesn’t work properly, leading to insufficient blood flow to the brain and causing dizziness or lightheadedness. You may also faint. This is caused by an abnormal regulation of blood pressure associated with changes in body position.

Orthostatic hypotension is caused by various factors. These include decreased elasticity of blood vessels with age, side effects of certain medications, dehydration, and autonomic nervous system disorders. Symptoms often appear immediately upon standing up, but they can also occur after a few minutes. It tends to happen particularly in the morning after waking up or after staying in the same posture for a long time. If this condition becomes chronic, diagnosis and treatment by a specialist may be necessary. Measuring blood pressure and heart rate before and after standing up provides clues for diagnosis to pinpoint the exact cause.

Dehydration and Low Blood Volume

Dehydration is a significant cause of dizziness when standing up. When the body doesn’t retain enough fluids, blood volume decreases. This requires extra effort for the heart to pump blood throughout the body, making it especially likely for blood flow to the brain to be insufficient when standing up. This can lead to low blood pressure and cause symptoms similar to orthostatic hypotension. It is likely to occur when you sweat a lot, have diarrhea or vomiting, or simply haven’t consumed enough fluids. Be cautious in hot environments or after exercise.

Dizziness due to dehydration can occur along with symptoms such as thirst, fatigue, reduced urine output, and dark-colored urine. Adequate fluid intake is very important for maintaining blood volume and preventing dizziness when standing up. Beverages containing electrolytes can also be effective in some cases. Especially for those who exercise a lot, the elderly, or those who cannot eat or drink sufficiently due to illness, conscious fluid intake is recommended. It is expected that dizziness symptoms will also be alleviated if the dehydration state is improved.

Medications

Certain medications can affect blood pressure and heart rate, potentially causing dizziness when standing up. These include medications for high blood pressure (especially diuretics, beta-blockers, alpha-blockers), heart medications, antidepressants, tranquilizers, Parkinson’s disease medications, and ED medications. These drugs can cause blood pressure to drop by dilating blood vessels or slowing down the heart’s function. If the drug’s effect is too strong, or if blood pressure drops too much due to changes in physical condition, it becomes easier to feel dizzy when standing up.

Taking multiple medications can also increase the likelihood of dizziness due to drug interactions. If dizziness appears after starting a new medication or changing the dosage of an existing medication, it’s important to consider that the medication might be the cause. Stopping or changing the dosage of medication on your own is dangerous. If you experience dizziness symptoms, it is crucial to consult with your prescribing physician to review the medication you are taking. Adjusting the type or dosage of the medication may improve dizziness.

Low Blood Sugar (Hypoglycemia)

Low blood sugar, or hypoglycemia, can also be a cause of dizziness when standing up. When blood sugar levels are lower than normal, the brain’s energy source, glucose, becomes insufficient, which can lead to dizziness and lightheadedness. This is particularly likely to occur if you skip meals, have gone a long time since your last meal, or are using diabetes medications (insulin or certain oral medications). It can also happen after strenuous exercise. Dizziness due to hypoglycemia often occurs suddenly and may be accompanied by other symptoms such as trembling hands and feet, cold sweats, palpitations, hunger, and difficulty concentrating.

If you feel dizzy due to hypoglycemia, it is recommended to consume foods containing glucose (juice, candy, sugar, etc.) immediately. This is expected to raise blood sugar levels and improve symptoms. Patients with diabetes must manage their diet and medication properly to prevent hypoglycemia by regularly measuring blood sugar levels. If dizziness occurs frequently, or if severe hypoglycemia symptoms appear, you should consult with your prescribing physician and review your treatment plan. Revising meal timing and content can also help prevent hypoglycemia.

Heart Problems

Heart problems can be a cause of dizziness when standing up. If the heart cannot efficiently pump blood throughout the body, blood flow to the brain is particularly likely to be insufficient when standing up. Arrhythmias (irregular heart beat), heart failure, and heart valve problems can be related. In these conditions, the regulation of heart rate and blood pressure may be impaired, and the body may not be able to cope with fluctuations in blood flow due to changes in posture, leading to dizziness.

Dizziness originating from the heart can occur with other symptoms such as chest pain, shortness of breath, palpitations, and fainting. Since these symptoms may be important signs of heart disease, you should seek medical help promptly without ignoring them. If heart disease is suspected, tests such as electrocardiogram, echocardiogram, and Holter monitor are performed to evaluate the heart condition in detail. If the cause is a heart problem, appropriate treatment can potentially improve dizziness symptoms. Regularly checking your heart health can help prevent various health problems.

Neurological Conditions

Certain Neurological Conditions (diseases of the nervous system) can also be associated with dizziness when standing up. The autonomic nervous system is responsible for regulating blood pressure and heart rate, and if this function is impaired, it can cause orthostatic hypotension and other circulatory dysregulation, making dizziness more likely. Parkinson’s disease, multiple system atrophy, and diabetic neuropathy are known to affect the autonomic nervous system. Also, dizziness and balance abnormalities can appear as symptoms of stroke or transient ischemic attack (TIA).

Dizziness due to brain or nervous system problems can occur with other symptoms such as numbness in the limbs, muscle weakness, difficulty walking (unsteady feeling when standing up and walking), vision abnormalities, and speech difficulties. These symptoms may suggest a serious neurological condition and may require emergency medical attention. Diagnosis involves neurological examinations, imaging such as MRI or CT scans, and autonomic nervous system function tests. If a Neurological Condition is the cause, treating the underlying disease can lead to improvement in dizziness.

Anemia (Iron Deficiency)

Anemia, particularly Iron Deficiency Anemia, can be a cause of dizziness when standing up. Anemia is a condition where the number of red blood cells or hemoglobin in the blood decreases, reducing the capacity to transport oxygen to tissues and organs throughout the body. When oxygen supply is insufficient, the brain is particularly sensitive, which can lead to dizziness and lightheadedness. When standing up, blood flow to the brain is prone to temporary reduction due to gravity’s effect, so symptoms are more likely to occur with Anemia.

Dizziness due to Anemia can be accompanied by symptoms such as fatigue, shortness of breath, pallor, and palpitations. Iron Deficiency Anemia can be caused by insufficient dietary iron intake, bleeding from the gastrointestinal tract (including hidden bleeding), or heavy menstrual bleeding in women. Anemia can be diagnosed with blood tests. In cases of Iron Deficiency Anemia, improvement can be expected by taking iron supplements or increasing dietary iron intake. Addressing the underlying cause is also important. If chronic fatigue or dizziness persists, it is recommended to undergo medical tests to check for Anemia.

Inner Ear Problems (Vertigo, Labyrinthitis)

Inner ear problems affect the function of the part of the body that controls balance, causing dizziness, especially vertigo accompanied by a spinning sensation. When you feel dizzy upon standing up, problems with the inner ear may be related. Benign paroxysmal positional vertigo (BPPV) is the most common inner ear disorder that causes brief, intense vertigo with specific changes in head position. It can be triggered by sudden movements such as standing up, lying down, or turning over in bed.

Also, Labyrinthitis and Meniere’s disease are known inner ear problems that cause symptoms such as dizziness, vertigo, hearing loss, and tinnitus. These symptoms can appear not only when standing up but also at rest. Dizziness caused by inner ear problems may also be accompanied by nausea and vomiting. Diagnosis involves examination by an otolaryngologist and balance function tests. Treatment varies depending on the condition and may include medication for symptom relief or treatment with specific head movements (in the case of BPPV).

Is It Normal to Get Dizzy When You Get Up?

Feeling dizzy temporarily when standing up, especially if you stand up quickly, can occasionally be within the range of a normal physiological response. This is lightheadedness caused by a slight delay in blood pressure regulation as the body adapts to a change in posture, and the symptoms disappear quickly. For example, after sitting or lying down for a long time, if you stand up with sudden movements, blood flow to the brain may temporarily decrease, causing slight dizziness. This is a reaction seen in the process of the body trying to adjust to a new posture.

However, if dizziness occurs frequently, the symptoms are severe, last for a long time, or are accompanied by other symptoms (fainting, chest pain, shortness of breath, vision abnormalities, numbness, etc.), it is not a normal state and may indicate an underlying medical condition. Especially in the elderly, those with chronic conditions, or those taking multiple medications, the causes of dizziness are often complex. If you notice changes in the frequency or nature of dizziness, it is important to consult a medical professional without self-diagnosing.

Related Symptoms: Feeling Dizzy and Can’t See or Nauseous

Dizziness when standing up is often accompanied by other symptoms. Visual symptoms include “Can’t See,” or visual disturbances such as blurred vision, the feeling of the vision going dark, or seeing spots. This happens because the function of the visual cortex is affected when blood flow to the brain is temporarily insufficient. These symptoms are particularly likely to appear during severe dizziness or lightheadedness. Nausea and vomiting can also occur. This is a reaction caused by stimulation of the inner ear or brainstem, which control balance. The stronger the dizziness, the stronger the nausea tends to feel.

These symptoms suggest that dizziness upon standing is related not only to simple temporary blood pressure fluctuations but also to more complex physiological reactions or an underlying condition. Severe dizziness accompanied by “Can’t See” or vomiting may require medical attention. The combination of symptoms provides important clues for identifying the cause. For example, if vertigo (spinning dizziness) is accompanied by nausea and tinnitus, an inner ear problem may be suspected, and if dizziness is accompanied by chest pain or shortness of breath, heart problems may be suspected. Clearly communicating your symptoms to your doctor will lead to an accurate diagnosis.

Dizziness When Standing Up and Walking

Dizziness or an unsteady feeling may persist not only immediately after standing up but also after you start walking. This can happen if your body hasn’t fully adjusted to the gravitational redistribution of blood flow, or if the act of walking itself places an additional burden on your body’s balance and blood flow regulation. Dizziness while walking can increase the risk of falling, so particular caution is needed. This symptom is common in the elderly, those with neurological conditions, inner ear problems, or those with decreased muscle strength or balance ability.

If dizziness while walking occurs frequently or if walking becomes unstable, causes other than Orthostatic hypotension should also be considered. For example, if peripheral neuropathy causes numbness in the feet or cerebellar ataxia impairs motor coordination, dizziness and balance problems may occur while walking. Vertigo due to inner ear problems may worsen during walking. If symptoms persist, it is recommended to consult a medical professional to assess walking ability and balance and identify the cause.

Should You Be Worried if You Get Dizzy When You Stand Up?

If the dizziness you feel when standing up is occasional and light, and improves rapidly, you generally do not need to worry excessively. However, depending on the nature and frequency of the dizziness, and the accompanying symptoms, medical attention may be necessary. If the dizziness is severe enough to interfere with daily life, occurs repeatedly, or is accompanied by certain dangerous symptoms, it may be a sign of a serious underlying condition. It is important not to ignore symptoms and to consult a medical professional.

There are several criteria for determining whether dizziness is a worrying symptom. For example, if you lose consciousness (fainting) during dizziness, if it is accompanied by chest pain or shortness of breath, if you have a sudden severe headache, if you have numbness or weakness on one side of the body, or if your vision suddenly changes (“Can’t See,” etc.). These symptoms may suggest heart problems, neurological conditions (such as stroke), or other serious conditions and may require emergency medical attention. Keeping a detailed record of your dizziness symptoms—specifically when, under what circumstances, and what symptoms appear—can be helpful when consulting with a doctor.

When to Seek Medical Help for Dizzy Spells

You should seek medical help promptly if your dizziness upon standing up fits any of the following conditions:

• Fainting: If you lose consciousness along with dizziness.
• Severe Symptoms: If the dizziness or Vertigo is very severe, making it difficult to stand up or walking.
• Persistent Symptoms: If the dizziness lasts for a long time or recurs frequently.
• Accompanying Dangerous Symptoms:
  • Chest pain, palpitations, or shortness of breath.
  • Severe headache.
  • Numbness or weakness on one side of the body.
  • Speech difficulties.
  • Sudden changes in vision (“Can’t See”, etc.).
  • Stiffness in the neck.
  • If you have fallen or injured yourself.

These symptoms may suggest heart problems, stroke, severe dehydration, serious neurological conditions, or other life-threatening conditions. Especially for the elderly or those with chronic conditions, the risk of dizziness being a sign of a more serious problem is higher, so it is crucial to consult a medical professional early. If you are taking Medications that could potentially cause Dizziness, you should also consult your prescribing doctor to review your Medication.

Dizzy Spells in the Elderly

In elderly individuals, dizziness when standing up is one of the common symptoms. With age, the function of the autonomic nervous system that regulates Blood pressure and Heart rate tends to decline, making Orthostatic hypotension more likely. Furthermore, the Elderly often have multiple chronic conditions, and these illnesses themselves, or the multiple medications taken for treatment, can cause dizziness. Cardiovascular diseases, Neurological Conditions, diabetes, Anemia, and Inner ear problems are conditions that are prone to causing dizziness in the Elderly.

Dizziness in the Elderly is a major risk factor for Falling. Since falls can lead to serious injuries such as fractures, dizziness symptoms should not be taken lightly. When dizziness is observed in Elderly individuals, it is extremely important to identify the cause and take appropriate measures. Review of Medications, management of underlying diseases, assessment of hydration and nutrition status, and if necessary, physical therapy or balance training may be recommended. Family members and caregivers should also pay attention to the dizziness symptoms in the Elderly and encourage them to consult a medical professional early.

How to Stop Getting Dizzy When I Stand Up

To alleviate or prevent dizziness when standing up, it is important to take measures according to the cause. If a Medical condition is the cause, treating it is fundamental. However, even without a Medical condition or when the cause is unknown, symptoms can sometimes be improved through some lifestyle adjustments and physical measures. The key is to avoid situations where dizziness is likely to occur and to support the body’s regulation of Blood pressure and Blood flow.

Lifestyle Adjustments

Lifestyle adjustments that can be incorporated into daily life are helpful in reducing dizziness when standing up.

• Stand up slowly: When getting up from a Sitting or lying down position, avoid Sudden movements and try to move slowly. First, sit for a while to rest, and then stand up slowly.
• Stay well-hydrated: Dehydration is a common cause of dizziness. It is important to consume fluids regularly, especially when it’s hot, after exercise, or when you are ill. Make sure to consume adequate fluids during Meals as well.
• Limit alcohol: Alcohol can cause dehydration and affect Blood pressure, so limiting consumption is recommended.
• Review salt intake: In some cases, under the guidance of a doctor, slightly increasing salt intake may help maintain Blood pressure (however, caution is needed if you have other conditions like high blood pressure).
• Adjust meals: After large meals, blood flow concentrates in the digestive system, which can make you feel dizzy when standing up. It may be better to eat small meals frequently.
• Compression stockings: Compression stockings can help reduce Orthostatic hypotension by preventing blood from pooling in the lower body and aiding blood flow back to the heart.
• Adjust sleeping posture: Sleeping with your head slightly elevated, such as by using an extra pillow, may help reduce morning Orthostatic hypotension.

Review with Your Doctor

If dizziness when standing up is persistent, severe, or accompanied by other worrisome symptoms, it is crucial to consult a medical professional for a thorough diagnosis. Self-diagnosis and self-treatment can be dangerous. Your Doctor will ask detailed questions about your symptoms, perform a Physical examination, and order necessary tests such as Blood tests, electrocardiogram, Blood pressure monitoring, Neurological evaluation, and Inner ear function tests.

When consulting with your Doctor, it’s helpful to be prepared to provide information on the following points:

• When the dizziness started and how often it occurs.
• The specific circumstances under which dizziness occurs (when, where, what change in body position triggers it).
• The nature of the dizziness (whether it’s spinning Vertigo or non-spinning Lightheadedness, etc.).
• How long the dizziness lasts.
• Any other symptoms that appear simultaneously (chest pain, shortness of breath, vision changes like Can’t See, Nauseous, numbness, weakness, etc.).
• All medications you are currently taking (including prescription drugs, over-the-counter drugs, and supplements).
• Your medical history (Chronic conditions and past illness).
• Lifestyle factors such as Alcohol consumption and eating habits.

Based on this information, your Doctor can identify the cause of your dizziness and recommend the optimal treatment and management strategies. Medication adjustments or changes, treatment of the underlying condition, physical therapy, or rehabilitation may be implemented as needed. Following your Doctor’s guidance is most important for improving dizziness and maintaining a safe daily life. If you are concerned, don’t hesitate to consult your doctor early.
