Dizziness when lying down?


In recent days, whenever I lie on my side to sleep, I experience dizziness.
Initially, it was only on my left side, but now it also occurs on my right side! Now, even when lying flat, I feel dizzy! During these episodes of dizziness, my vision spins uncontrollably! Currently, I even feel lightheaded when I'm not lying down! I recently visited a traditional Chinese medicine practitioner who prescribed me some herbal medicine.
Could this be related to the herbal medication I'm taking? However, I didn't experience any issues in the days leading up to taking the medicine! This sudden change—could it be related to my long-term habit of staying up late and sleeping excessively? I often go two days without sleep, and when I do sleep, it's for two to three days straight! During those two to three days, aside from eating and using the restroom, I'm mostly just in bed sleeping heavily.

Dr. Xiao Yongxun reply Internal Medicine


Dear Ms.
Chen: Changes in posture can lead to dizziness for various reasons, including peripheral causes such as vestibular neuritis, Meniere's disease, otolith dysfunction, and hearing loss.
Central causes may also be involved, such as brainstem lesions, nerve compression, or increased intracranial pressure.
Based on your symptoms and age, it is likely due to inner ear circulation imbalance.
For a detailed diagnosis, it is essential to consult an otolaryngologist or a neurologist.
Additionally, maintaining a normal lifestyle is important.
In simple terms, overexerting your body may lead to premature health issues.

More Info


Dizziness when lying down can be a perplexing and distressing symptom, and it can arise from various underlying causes. Your description of experiencing dizziness when lying on your side or even when lying flat suggests that it may be related to positional changes or inner ear issues, but it could also be influenced by other factors such as sleep patterns, medication, or even stress.

One common cause of dizziness when changing positions 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 episodes of vertigo triggered by changes in head position. BPPV is typically characterized by brief episodes of dizziness that can be quite intense but usually resolve quickly. If you notice that your dizziness is triggered specifically by turning your head or changing positions, this could be a possibility.

Another potential cause is vestibular neuritis or labyrinthitis, which are conditions that involve inflammation of the inner ear structures responsible for balance. These conditions can lead to prolonged episodes of dizziness and may be associated with viral infections. If you have experienced any recent upper respiratory infections, this could be a contributing factor.

Your mention of dizziness occurring even when not lying down, along with a feeling of "seeing the world spinning," raises the possibility of other issues such as migraines or even anxiety-related dizziness. Migraines can sometimes present with dizziness or vertigo, even in the absence of a headache. Anxiety can also lead to sensations of dizziness, especially if you are experiencing stress or sleep deprivation.

Sleep patterns play a significant role in overall health, and irregular sleep can contribute to feelings of dizziness and fatigue. Chronic sleep deprivation can affect your body's ability to function properly, leading to symptoms such as dizziness, difficulty concentrating, and mood changes. It’s important to establish a regular sleep schedule and ensure you are getting adequate rest.

Regarding the use of traditional Chinese medicine (TCM) and the medications you have been prescribed, it is essential to consider that some herbal remedies can have side effects or interactions that may contribute to dizziness. If you suspect that your dizziness may be related to the TCM medications, it would be wise to consult with the practitioner who prescribed them or a healthcare professional who can evaluate your symptoms in the context of your treatment.

In terms of solutions, here are a few recommendations:
1. Consult a Healthcare Professional: Given the complexity of your symptoms, it is crucial to consult with a healthcare provider who can perform a thorough evaluation, including a physical examination and possibly imaging studies or vestibular testing.

2. Vestibular Rehabilitation: If diagnosed with BPPV or other vestibular disorders, a physical therapist specializing in vestibular rehabilitation can provide exercises to help manage and reduce dizziness.

3. Sleep Hygiene: Establish a regular sleep routine, aiming for 7-9 hours of quality sleep per night. Avoid stimulants like caffeine and screens before bedtime.

4. Hydration and Nutrition: Ensure you are well-hydrated and consuming a balanced diet, as dehydration and poor nutrition can exacerbate dizziness.

5. Stress Management: Engage in relaxation techniques such as deep breathing, meditation, or yoga to help manage stress, which can contribute to dizziness.

6. Monitor Symptoms: Keep a diary of your symptoms, noting when they occur, their duration, and any potential triggers. This information can be valuable for your healthcare provider.

In conclusion, dizziness when lying down can stem from various causes, including vestibular disorders, sleep issues, and anxiety. A comprehensive evaluation by a healthcare professional is essential to determine the underlying cause and appropriate treatment.
