When impairment in stability or spatial perception occurs you are likely to feel dizzy. While dizziness is not attributed precisely to a specific condition, there are a range of factors that contribute towards the state and feeling. This article provides a detailed perspective on conditions, illnesses and diseases associated with dizziness and giddiness.

Dizziness is a feeling of being unbalanced, giddy or light-headed. It’s a disoriented feeling that can lead a person to lose balance or faint. While dizziness may attribute to a primary or secondary condition, the feeling of dizziness or giddiness can be induced by certain activities that involve spinning. The sensory organs, eyes and ears in particular are affected when a person feels dizzy. Three conditions often associated with dizziness are vertigo, disequilibrium, and presyncope.


Vertigo is a medical condition where the person experiences the feeling of spinning or swaying in a violent or mild manner. Individuals experiencing a bout of vertigo feel like everything around is moving sideways, up-and-down or spinning.

The feeling of vertigo is disturbing and maybe accompanied with nausea, sweating and vomiting. If individuals are lying on a bed and experience a bout of vertigo they have difficulty waking up as the head is moved. When individuals experience a bout of vertigo while standing or walking they are likely to feel wobbly and sway with awkward movements feeling dizzy. During this bout a person may sit on the ground or stumble to the ground trying to hold onto something or someone.


A feeling of being off balance is associated with disequilibrium. Frequent falls are associated with this feeling. While falls are specifically in a direction, nausea and vomiting seldom occur.


This is a feeling of lightheadedness accompanied with blurred vision and muscular weakness. A person feels like he/she is going to faint in this state. The feeling of dizziness or lightheadedness often associated with orthostatic hypotension which results from a drastic fall in blood pressure when a person is in a sitting position or lying position.

In some cases a mild stroke can cause isolated dizziness. More than 25% of cases in which dizziness occurs are associated with vertigo.

Causes of Dizziness

The feeling of dizziness or giddiness may be caused by an underlying condition or due to varied conditions. A number of body systems that include eyes, inner ear, skeleton, muscles and nervous system need to work together as a cohesive unit to ensure proper balance. When the sense of balance is interrupted it can cause nausea, disorientation or dizziness. While imbalance may occur due to different conditions, the common conditions associated with imbalance are Meniere’s disease, a inner ear disorder/infection or a bad common cold that affects the nose, throat and results in clogged ears.
