During a video call with a friend, I suddenly felt very heavy-headed and collapsed onto the floor, lying there for four hours.
My friend called me repeatedly, but I didn't hear any ringing at all.
When I finally got up, my head felt heavy and my legs felt light...

Hello, based on your description, generally speaking, head trauma without loss of consciousness, the use of anticoagulants, or obvious local hematomas tends to be mild.
However, if there are instances of fainting, it is important to continue monitoring.
Common causes of fainting include: 1.
Neurogenic reflexes leading to decreased peripheral vascular tone, resulting in blood pooling in peripheral tissues and insufficient blood flow to the brain.
2.
Orthostatic hypotension caused by changes in posture, such as suddenly standing up or getting out of bed.
Conditions like autonomic dysfunction and the use of cardiovascular medications can contribute to this.
3.
Narrowing, obstruction, or insufficient blood flow in local cerebral vessels.
4.
Blood-related issues such as hypotension or hypoglycemia.
5.
Seizures can sometimes cause sudden falls that resemble fainting.
It is advisable to consult a neurologist or cardiologist for further evaluation and treatment.
Wishing you good health and peace.

More Info

Feeling dizzy and heavy-headed can be concerning, especially when it leads to a situation where you lose consciousness or cannot respond to stimuli, as you described. There are several potential neurological and medical explanations for these symptoms, and understanding them can help you determine the next steps for your health.

First, dizziness can be categorized into two main types: vertigo and non-vertigo dizziness. Vertigo is often described as a spinning sensation, while non-vertigo dizziness can feel more like lightheadedness or a sense of imbalance. The heaviness in your head, combined with the inability to stand, may suggest a few different underlying issues.

1. Neurological Causes: Conditions such as migraines, transient ischemic attacks (TIAs), or even strokes can present with symptoms of dizziness and heaviness in the head. Migraines can cause aura symptoms, which may include dizziness and a feeling of heaviness. TIAs, often referred to as "mini-strokes," can cause temporary neurological symptoms that resolve quickly but indicate a risk for future strokes. If you have a history of migraines or vascular issues, this could be a relevant consideration.

2. Vestibular Disorders: The vestibular system, located in the inner ear, helps control balance. Disorders such as Benign Paroxysmal Positional Vertigo (BPPV) or vestibular neuritis can lead to dizziness and a sensation of heaviness. These conditions often require specific maneuvers or therapies to alleviate symptoms.

3. Orthostatic Hypotension: This condition occurs when blood pressure drops significantly upon standing, leading to dizziness and a feeling of heaviness. If you were lying down for an extended period, standing up too quickly could cause this sensation. It’s essential to rise slowly and ensure you are well-hydrated.

4. Anxiety and Panic Attacks: Psychological factors can also contribute to feelings of dizziness and heaviness. Anxiety can lead to hyperventilation, which may cause lightheadedness and a sensation of heaviness in the head. If you have a history of anxiety, this could be a contributing factor.

5. Dehydration or Nutritional Deficiencies: Lack of hydration or essential nutrients (like electrolytes) can lead to dizziness and feelings of heaviness. If you’ve been ill, sweating excessively, or not eating properly, this could be a factor.

6. Medication Side Effects: If you are taking any medications, it's important to consider whether dizziness or heaviness could be side effects. Some medications can cause sedation or affect balance.

Given the severity of your symptoms, especially the inability to respond to your friend and the prolonged period of lying down, it is crucial to seek medical attention promptly. A healthcare professional can conduct a thorough evaluation, including a physical examination, neurological assessment, and possibly imaging studies or blood tests, to determine the underlying cause of your symptoms.

In summary, dizziness and a heavy head can stem from various neurological and medical issues, ranging from migraines and vestibular disorders to anxiety and dehydration. It is essential to consult with a healthcare provider to receive an accurate diagnosis and appropriate treatment. Early intervention can be vital in managing any underlying conditions effectively.
