Positional Vertigo (BPPV): Why Does the Room Suddenly Start Spinning?

Have you ever turned in bed, looked up, or bent down - and suddenly felt like the entire room was spinning?

If yes, you may be experiencing Benign Paroxysmal Positional Vertigo (BPPV), the most common cause of positional vertigo.

What is Positional Vertigo?

BPPV is a condition where brief episodes of dizziness or spinning occur with specific head movements, such as :

• Turning in bed

• Getting up from lying down

• Looking up

• Bending forward

• Turning your head quickly.

The spinning sensation usually lasts less than a minute but can be intense enough to make you feel anxious or lose your balance.

Why Does It Happen?

Your inner ear contains tiny calcium crystals that help maintain balance. Sometimes, these crystals become displaced and move into the balance canals of the inner ear.

When you move your head, these misplaced crystals send incorrect signals to the brain, creating the sensation that the room is spinning—even though you’re perfectly still.

Do You Need an MRI?

In most cases of BPPV, the brain is completely normal. Diagnosis is usually made through a simple clinical assessment by a physiotherapist trained in vestibular rehabilitation, and MRI or CT scans are often unnecessary unless another neurological condition is suspected.

How Can Physiotherapy Help?

The most effective treatment for BPPV is the Canalith Repositioning Maneuver.

A vestibular physiotherapist uses a series of gentle head movements to guide the displaced crystals back to their correct position.

This treatment is :

• Safe and non-invasive

• Drug-free

• Highly effective

• Often provides relief in just one or two sessions

Medication vs Physiotherapy

Medicines may temporarily reduce dizziness, but they do not correct the underlying cause. Vestibular physiotherapy treats the source of the problem, helping prevent recurring episodes.

When Should You See a Physiotherapist?

Seek professional help if you experience :

• Spinning dizziness when changing head positions

• Recurrent vertigo while turning in bed

• Dizziness when looking up or bending down

• Loss of balance associated with head movements

The Bottom Line

Positional Vertigo (BPPV) is one of the most treatable causes of dizziness. With an accurate diagnosis and expert vestibular physiotherapy, most patients recover quickly and safely without relying on long-term medication.

If head movements trigger dizziness, don’t ignore it. Early assessment and the right physiotherapy treatment can help you regain your balance and confidence.
