Dizziness: types, most common causes, symptoms and treatments

It’s very hot. We did not eat. We traveled by car. We get up abruptly after lying for a long time. It is likely that in some of these situations, we have suddenly experienced dizziness that threatens to knock us to the ground or make us dizzy.

Most people are familiar with and may have suffered from dizziness throughout their lives. But what is it and why is it happening? In this article we will go to talk about dizziness, its causes, symptoms and treatment.

    Vertigo: definition and main symptoms

    The concept of vertigo refers to a sudden, sharp feeling of discomfort which appears in various situations such as sudden movements, blood sugar alterations or stress. It is not a disorder per se, but it is usually a symptom that there is some kind of alteration in our body.

    The main symptoms that indicate that we have dizziness are the presence of vertigo (which makes things seem like things are turning around) and the feeling of altered or narrowed consciousness in the form of stuffing, Which can be accompanied by a limitation of the perceptual field to which we are addressing.

    Blurred vision, headaches and restlessness are common. Another typical feature is postural instability and loss of muscle tone. It usually changes the cardiorespiratory rhythm and it is not uncommon for digestive symptoms such as nausea or vomiting to appear as well.

    This sometimes leads to temporary loss of consciousness, in the form of syncope, and we may experience mental sluggishness and difficulty speaking, as well as profuse sweating and ringing in the ears.

      Types of dizziness

      There are several classifications of dizziness based on aspects such as their persistence or how they appear, although they can appear in different disorders and syndromes such as dizziness. Below we will see one of them, especially the one reflected by GAES.

      1. Acute dizziness

      This type of dizziness comes on suddenly and lasts for a few hours before going away on its own, as if it were an epidemic. This epidemic will reappear some time later. It often appears alongside hearing loss.

      2. Sudden dizziness

      It is characterized by a sudden onset of feelings of instability and discomfort. Although it persists for a period that can last for months, it decreases over time. In this type is the well-known benign postural vertigo, Caused by sudden movements or inflammation of the ear.

      3. Persistent dizziness

      Most disturbing since it is often associated with nervous or brain disorders or even tumorsPersistent dizziness is one that occurs insidiously and gradually increases over time.

      Why are they happening?

      The causes of dizziness are generally minor and easily treatable, although it should always be borne in mind that they may be a symptom of the existence of more or less severe pathologies.

      In this way, it is not a bad idea to go to a doctor if it is accompanied by other symptoms or a specific cause cannot be attributed to it. The alteration usually occurs in the vestibular system or affects it or the integration of the information it provides.

      1. Nutrition and hydration

      One of the reasons we may have dizziness is related to excessive presence or absence of certain nutrients in our body through our diet, or in the absence of hydration.

      For example, one of the most common times when we feel dizzy is when we suffer from hypoglycemia. In these cases, the lack of sufficient blood sugar causes weakness and dizziness which can lead to fainting.

      The vertigo of this disorder can be caused by not eating enough or being anemic, exercising in a way that burns blood sugar, or suffering from illnesses such as diabetes (in which case it can be dangerous. and you need to consume sugar quickly). In addition, the absence of other essential components such as iron can cause dizziness due to anemia.

        2. Blood pressure

        Another reason why dizziness can occur is high or low blood pressure. Being exposed to excessive temperatures it can make us dizzy. The same can be said of the lack of hydration.

        3. Movement

        Another of the reasons why dizziness can appear is the performance of accelerating or decelerating movements that cause our visual and vestibular system to contradict each other. for example in the face of sudden and rapid movements or when traveling in different types of vehicles (this is the case of motion sickness or motion sickness).

        4. Hormones and drugs

        Taking certain medications can cause dizziness as a side effect as well as hormones. It is not uncommon for example that during menstruation or pregnancy may appear.

        5. Serious illnesses

        As we have said sometimes, the changes that cause dizziness can be serious. Dizziness may indicate the existence of cardiovascular problems such as myocardial or cerebral infarction, diabetes mellitus (Whether or not this is known to the patient in advance), changes in the composition of the blood, infections such as herpes, problems with the spine or the inner ear, or even tumors.

        Finally, we can find dizziness caused by psychological causes: stress, depression, anxiety or phobias sometimes generate this type of discomfort.


        In most cases, dizziness occurs sporadically and does not require treatment. However, in cases where the treatment to be used will depend on the specific cause of the vertigo.

        For example, if it is due to a medical illness, the treatment in question will depend on the affected area that is causing it and the illness itself. In case of anemia or food problems they should begin to introduce changes in the diet, as well as guide the performance of the exercise as appropriate.

        Increase blood pressure through hydration or administration of drugs or serum as appropriate may also be necessary, as well as to avoid exposure to high temperatures for too long. It is often strongly recommended that you establish adequate rest periods, eat well and lead an active lifestyle.

        In case of dizziness related to psychological problems such as stressThe use of tranquilizers and the performance of therapies such as addiction or relaxation are very helpful, as can learning new ways to deal with situations can be very helpful.
