Dizziness refers to a range of sensations, such as feeling as if the room is rotating, dizziness, and a feeling of physical instability has many possible causes, which may be related to a person’s external environment, medications, or underlying condition.

Frequent dizziness or severe dizziness can interfere significantly with a person’s life. Rarely refers to a medical emergency. People can feel dizzy after:

  • Spin quickly
  • Stand up or sit very quickly
  • Engage in high-intensity exercises

Normally, people will be able to determine the cause of vertigo. However, these symptoms may occur unexpectedly or without any obvious reason.

Causes of dizziness can range from temporary physical changes to the most serious underlying medical conditions, some of which we will explain in detail below.

Many people use the terms “dizziness” interchangeably. Although these conditions create similar sensations, they are slightly different. When someone feels dizzy, they can feel dizzy or confused. On the other hand, the rotor refers to the artificial sensation of motion. Vertigo can cause people to feel as if their surroundings are rotating or tilting. Vertigo occurs due to the development of problems with the inner ear. Causes of vertigo can include:

Benign paroxysmal positional vertigo

Benign paroxysmal positional vertigo occurs when calcium carbonate molecules accumulate in the inner ear canals. These channels send information about the body’s position and movements to the brain, but the presence of calcium molecules makes the brain misread information.


The infection can cause inflammation of the inner ear. Inflammation of the ear tends to develop after a viral infection, such as cold or flu.

Antiviral and antihistamines can effectively treat otitis. However, parts of the inner ear may be permanently damaged as a result of this condition.

Ménière disease

There is no known cause of this inner ear condition, but some scientists believe it can occur when fluid accumulates in the ear canals.

Munir’s disease can develop suddenly and without any obvious reason. It can lead to dizziness, ringing or roaring in the ears, and hearing loss.

Motion sickness

The repeated movement of vehicles, such as a car, plane or boat, can disrupt the internal ear structures, causing dizziness, nausea and vomiting. People call this “motion sickness” or “seasickness.”

Pregnancy or taking certain medications can increase a person’s sensitivity to movement and increase your risk of motion sickness. Symptoms of motion sickness usually subside as soon as a person puts his foot on solid ground.


Migraine is a type of frequent headache that can cause pulsating pain on one side of the head. Sometimes, people suffer from dizziness before the onset of a migraine attack. Other neurological symptoms, or halos, can precede migraine pain. Halos can affect a person’s vision, speech, and motor control.

Low blood pressure

A sharp drop in blood pressure can cause a short sense of dizziness. Changes in blood pressure can occur after sitting or standing too fast. Other conditions that can cause changes in blood pressure include:

  • Drought
  • Blood loss
  • Severe allergic reaction, or anaphylaxis
  • Pregnancy

Taking certain medications, such as diuretics, beta blockers or antidepressants, can lead to changes in blood pressure.

Cardiovascular diseases

Conditions that affect the cardiovascular system, such as the accumulation of plaque in the arteries and congestive heart failure, can cause dizziness. People may experience dizziness before or after a heart attack or stroke.

If a person suffers from cardiovascular disease, it is likely to suffer from other signs and symptoms, including:

  • Heart rhythm disorder
  • Shortness of breath
  • Discomfort or tightness in the chest
  • Persistent cough
  • Excess fluid in the arms, legs or feet
  • Fatigue
  • Nausea and vomiting or both

Low iron

Iron deficiency can lead to a condition called anemia, where the body does not have enough oxygen-rich blood. Anemia can cause the following symptoms:

  • Dizziness
  • Shortness of breath
  • Chest pain
  • Fatigue

Making appropriate dietary changes and taking iron supplements can help treat mild forms of iron deficiency anemia. People with severe iron deficiency may need a blood transfusion.


Hypoglycemia occurs when blood glucose or blood sugar is below normal levels. Causes of hypoglycemia include:

  • Avoid diets
  • Drinking alcohol
  • Take certain medications, such as insulin or aspirin
  • Hormonal imbalances

Symptoms of hypoglycemia can suddenly appear and vary in severity. Some of these symptoms include:

  • Dizziness
  • Loss of balance
  • Fatigue
  • Headache
  • Hunger
  • Mood changes
  • Difficulty concentrating
  • Heart rhythm disorder

Autoimmune inner ear diseases

Autoimmune ear disease (AIED) refers to any condition in which the immune system accidentally attacks the inner ear. AIED can cause hearing loss in one or both ears. Other symptoms of AIED include:

  • Dizziness
  • Tinnitus, or ringing in the ears

Loss of balance or coordination

AIED causes unspecified symptoms similar to those of otitis. In order for doctors to accurately diagnose AIED, they need to have a full medical history, perform a physical examination and track any additional symptoms. People with AIED may develop another autoimmune disease that affects the entire body.


Long-term or chronic stress may contribute to major health problems, such as depression, anxiety, heart disease, diabetes or weakened immunity. During stress response, the brain secretes hormones that affect cardiovascular and respiratory systems. These hormones narrow blood vessels, raise heart rate, and cause rapid shallow breathing. These responses can lead to dizziness. Other symptoms of stress include:

  • Sweating
  • Headaches
  • Chest pain
  • Quick heartbeat
  • Difficulty sleeping
  • Difficulty concentrating
  • Nausea


Dizziness is a common symptom of anxiety. However, the exact relationship between the two varies between people. Some people may experience anxiety attacks that cause dizziness, while others may experience a sudden appearance of dizziness that leads to an anxiety attack. Stressful events, such as exam or difficult emotional situations, can lead to anxiety attacks. People may feel dizzy, confused and nauseous during an anxiety attack. Other symptoms of anxiety include:

  • Anxiety
  • Insomnia
  • Difficulty concentrating
  • Sleep problems
  • Mood changes
  • Irritability
  • Rapid heartbeat
  • Headache
  • Sweating
  • Dry mouth

When to visit a doctor

Dizziness may indicate a more serious underlying medical condition when it occurs along with symptoms such as:

  • Double vision
  • Vomiting
  • Fever
  • Numbness
  • Difficulty moving or controlling the arms or legs
  • Headache
  • Chest pain
  • Loss of consciousness
