Dizziness: Causes and When to Seek Neurological Help - Neurology

Dizziness, lightheadedness, or mild vertigo?


For the past one and a half months, I have been experiencing dizziness (lightheadedness, heaviness) upon waking up in the morning while lying in bed.
When I sit up, it feels okay, but when I stand and walk, I feel dizzy (lightheaded) and lose my sense of balance, making my gait unstable and somewhat wobbly, which makes it difficult to walk straight.
I also feel lethargic, which is significantly worse than my usual condition.
Additionally, when I sit or stand with my upper body leaning back for a period of time (about 5 seconds or more), I experience dizziness (lightheadedness) or slight vertigo.
Similarly, when I bend my upper body forward to look down, I feel the same.
At night, before getting up to use the bathroom, I experience dry mouth and difficulty walking straight, often swaying.

Could you please advise me, Dr.
Peng, on what might be the cause of my symptoms? Which hospital or type of specialist should I consult in New Taipei City or Taipei City? Thank you!

Hello, based on your symptoms, postural changes in blood pressure and heart rate, as well as postural dizziness and inner ear imbalance, could all be potential causes.
It is recommended that you visit a major hospital's neurology or otolaryngology outpatient clinic (you can search for physicians specializing in "dizziness").

More Info


Dizziness can be a complex symptom with various potential causes, and understanding its origins is crucial for effective management. Based on your description, it seems you are experiencing dizziness primarily upon standing, which may indicate a condition known as orthostatic hypotension. This occurs when blood pressure drops significantly upon standing, leading to feelings of lightheadedness or dizziness. Other potential causes of dizziness include vestibular disorders, neurological conditions, dehydration, or even medication side effects.

Given the symptoms you described—dizziness upon standing, difficulty maintaining balance, and a general sense of fatigue—it's essential to consider several factors. First, the sensation of dizziness that worsens with position changes could suggest issues with your vestibular system, which is responsible for balance. Conditions such as Benign Paroxysmal Positional Vertigo (BPPV), vestibular neuritis, or Meniere's disease could be contributing factors. Additionally, neurological issues such as migraines or even more serious conditions like multiple sclerosis could manifest with similar symptoms.

The fact that you also experience dryness of the mouth and a general sense of fatigue could indicate dehydration or other systemic issues. It's important to ensure you are adequately hydrated, as dehydration can exacerbate dizziness and lead to further complications.

When to Seek Help:
You should seek neurological help if:
1. Your dizziness persists or worsens over time.

2. You experience additional symptoms such as severe headaches, vision changes, difficulty speaking, or weakness in your limbs.

3. You have a history of cardiovascular issues or if you are on medications that could affect your blood pressure.

4. You notice any changes in your cognitive function or memory.

In terms of where to seek help, in New Taipei City or Taipei, you should look for a reputable hospital with a neurology department. Hospitals such as National Taiwan University Hospital, Taipei Veterans General Hospital, or Chang Gung Memorial Hospital are well-regarded and have specialists who can evaluate your condition. You may want to consult with a neurologist who specializes in dizziness and balance disorders. They may perform a thorough evaluation, including a physical examination, blood tests, and possibly imaging studies like an MRI or CT scan, to rule out any serious underlying conditions.

Additionally, a referral to an otolaryngologist (ENT specialist) may be beneficial, especially if vestibular issues are suspected. They can conduct specific tests to assess your inner ear function and balance.

In conclusion, dizziness can stem from a variety of causes, and it’s crucial to have a comprehensive evaluation to determine the underlying issue. Don't hesitate to seek medical attention, especially if your symptoms are affecting your daily life. Early intervention can lead to better outcomes and help you regain your balance and overall well-being.
