Dizziness and vertigo?

In recent weeks, whenever I lie down and move my head, I experience dizziness, as if the room is spinning, and I also feel nauseous.
Please provide an explanation, doctor.

Hello: Dizziness can generally be classified based on the location of the lesion into "peripheral dizziness" and "central dizziness." Peripheral dizziness refers to dysfunction in the structures of the inner ear that manage balance, such as the semicircular canals, utricle, and saccule.
This can be caused by factors such as small vessel occlusion, viral infections, otolith deposits, or medication side effects.
It can be categorized by etiology into benign paroxysmal positional vertigo (BPPV), Meniere's disease, vestibular neuritis, and transient hearing loss, among others.
Symptoms typically include severe nausea and vomiting due to dizziness, tinnitus, a feeling of fullness in the ears, and instability during the acute phase; however, there are generally no symptoms of diplopia, dysarthria, or dysphagia.
The condition usually resolves naturally within about 1-2 weeks.
Central dizziness, on the other hand, is caused by lesions in the brainstem, cerebellum, or the eighth cranial nerve.
Possible pathogenic mechanisms include stroke, tumors, vascular malformations, demyelinating diseases, or drug toxicity (such as certain antibiotics).
In addition to dizziness, symptoms often include diplopia, dysarthria, swallowing difficulties, and weakness in the limbs.
Imaging studies of the head are necessary to further differentiate the underlying causes.
Based on your description, it seems more likely to be peripheral dizziness.
However, it is unclear whether you are experiencing symptoms such as diplopia, dysarthria, swallowing difficulties, or limb weakness.
If the condition has persisted for several weeks without significant improvement, I recommend seeking assistance from a neurologist as soon as possible.
Wishing you a speedy recovery.

More Info

Dizziness and spinning sensations, often described as vertigo, can be quite distressing and may indicate underlying neurological or vestibular issues. The symptoms you are experiencing—dizziness upon moving your head while lying down, accompanied by a spinning sensation and nausea—are commonly associated with vestibular disorders, which affect the inner ear and brain's ability to process sensory information related to balance and spatial orientation.

One of the most common causes of such symptoms is Benign Paroxysmal Positional Vertigo (BPPV). This condition occurs when tiny calcium crystals in the inner ear become dislodged and move into one of the semicircular canals, leading to brief episodes of dizziness when the head is moved in certain positions. BPPV is typically characterized by sudden, intense episodes of vertigo triggered by changes in head position, such as rolling over in bed or looking up.

Another potential cause could be vestibular neuritis or labyrinthitis, which are inflammatory conditions of the inner ear that can result from viral infections. These conditions can cause prolonged episodes of vertigo, imbalance, and sometimes hearing loss. Migraines can also lead to dizziness and vertigo, often referred to as vestibular migraines, where patients may experience dizziness, spinning sensations, and nausea without the typical headache.

In more serious cases, dizziness can be a sign of neurological issues such as a transient ischemic attack (TIA) or stroke, particularly if accompanied by other symptoms like weakness, difficulty speaking, or severe headache. Therefore, it is crucial to consider the context of your symptoms, including their duration, frequency, and any accompanying signs.

To address your symptoms, it is advisable to consult a healthcare professional, preferably a neurologist or an ear, nose, and throat (ENT) specialist. They may perform a thorough evaluation, including a physical examination, a detailed medical history, and possibly imaging studies like an MRI or CT scan to rule out any serious conditions. Additionally, vestibular function tests may be conducted to assess the inner ear's balance mechanisms.

Treatment options will depend on the underlying cause of your dizziness. For BPPV, specific maneuvers such as the Epley maneuver can help reposition the dislodged crystals in the inner ear. Medications may be prescribed to alleviate nausea and dizziness, and vestibular rehabilitation therapy can be beneficial in improving balance and reducing dizziness over time.

In summary, while dizziness and spinning sensations can stem from various causes, it is essential to seek medical advice to determine the underlying issue and receive appropriate treatment. Early intervention can significantly improve your quality of life and prevent potential complications. If your symptoms worsen or are accompanied by concerning signs, do not hesitate to seek immediate medical attention.
