Approach to patient with giddiness can be a challenging task for clinicians. Giddiness is a common symptom and may be multifactorial leading to a wide range of differential diagnoses. A thorough history focused examination and appropriate investigation are necessary to arrive at the correct diagnosis. In this blog post we will discuss the approach to a patient with giddiness and the common causes of this symptom.
History Taking:
The first step in the approach to a patient with giddiness is to obtain a detailed medical history. A comprehensive medical history can often provide vital clues to the possible causes of giddiness. The following questions can be asked to the patient:
- Duration: The duration of giddiness is crucial in identifying the likely causes. It can be acute subacute or chronic.
- Onset: Was the onset sudden or gradual? Sudden onset suggests a more life-threatening condition than gradual onset.
- Quality: The quality of giddiness can also help in identifying the underlying cause. Ask the patient if they feel light-headed spinning floating rocking swaying or unsteady.
- Associated Symptoms: Many underlying causes of giddiness can present with additional symptoms. Ask if there are associated symptoms such as hearing loss tinnitus headache palpitations chest pain or shortness of breath.
- Triggers: Identify if giddiness is triggered by any particular situation such as postural changes head movements or exposure to bright lights.
- Medication history: A detailed medication history is necessary to identify any drug-induced giddiness.
- Past history: Medical comorbidities previous surgeries head injury or prior episodes of giddiness can also help in identifying the cause.
Examination:
After taking a detailed medical history a focused examination is necessary to identify the signs associated with giddiness. A comprehensive examination includes the following:
- Vital Signs: Blood pressure and heart rate should be measured in supine and upright positions to identify any orthostatic changes.
- Neurological Examination: A detailed examination of cranial nerves cerebellar function gait and coordination is necessary to evaluate the vestibular system.
- Cardiovascular Examination: Examination of the heart and peripheral pulses should be carried out to identify any cardiovascular abnormalities.
- ENT Examination: Examination of the ear nose and throat is essential to identify any vestibular or auditory disorders.
- Ophthalmic Examination: Fundoscopy and examination of the eye movements can help identify any ocular issues.
Investigation:
After taking a medical history and carrying out an examination appropriate investigations should be initiated to confirm the diagnosis. The following investigations can be carried out:
- Blood Tests: Basic blood tests such as complete blood count (CBC electrolytes renal function and liver function tests can be carried out to identify any metabolic or hematological disorders.
- Imaging Studies: Imaging studies such as CT Scan MRI or plain X-Ray may be necessary in specific cases to identify any structural abnormalities.
- Audiometric Tests: Hearing tests can be carried out to identify any sensorineural or conductive hearing loss.
- Electro-oculography (EOG): EOG is useful in evaluating the vestibular system.
- Echocardiography: Cardiac evaluation may be necessary in conditions such as arrhythmias or heart failure.
Differential Diagnosis:
The causes of giddiness are vast and varied and a wide range of differential diagnoses should be considered by the clinician. The following are some of the common causes of giddiness:
- Benign Paroxysmal Positional Vertigo (BPPV): This is the most common cause of giddiness and can occur with head movements. BPPV is due to the movement of otoconia in the semicircular canals.
- Vestibular Migraine: Vestibular migraine is a type of migraine that presents with giddiness and usually there are associated headaches.
- Meniere’s disease: It is a triad of symptoms that include giddiness hearing loss and tinnitus.
- Labyrinthitis: An infection of the inner ear that presents with sudden onset of giddiness hearing loss and tinnitus.
- Acoustic Neuroma: A benign tumor of the vestibular nerve.
- Orthostatic hypotension: A fall in blood pressure on standing leads to giddiness and unsteadiness.
- Cardiovascular disorders such as arrhythmias heart failure or cardiomyopathies.
- Hypoglycemia: Blood glucose levels falling below normal ranges can cause giddiness.
- Anxiety or panic attacks: Anxiety or panic attacks can present with the symptoms of giddiness.
Conclusion:
In conclusion the approach to a patient with giddiness requires a comprehensive medical history focused examination and appropriate investigations. It is essential to consider a wide range of differential diagnoses when assessing a patient with giddiness. A thorough understanding of the underlying causes of giddiness is necessary to provide the appropriate treatment and management plan. In severe cases referral to a specialist such as a neurologist or an otolaryngologist may be required.
