Gangrene

The term dizziness is used to describe everything from feeling lightheaded to feeling weak and unsteady. This creates a sense that you or your surroundings are spinning or moving which is called vertigo. Dizziness is often caused by a decrease in blood supply to the brain while vertigo may be caused by disturbances of the inner ear and balance centers of the brain. Causes of vertigo include: • Vestibular migraine • Inflammation in the ear • Acoustic neuroma- A non-cancerous (benign) growth on the vestibular nerve which connects the inner ear to your brain. • Benign paroxysmal positional vertigo- This causes intense brief episodes of vertigo immediately following a change in the position of your head, often when you turn over in bed or sit up in the morning. • Meniere's disease- Involves excessive build up of fluid in your inner ear. Dizziness could be caused due to a loss of balance, and the causes for loss of balance include: • Failing vision or a damage to any nerve in one's legs.  • Parkinson's disease and cerebellar ataxia that affects the nervous system • Inner ear problems • Medications such as sedatives, tranquilizers, and anti-seizure drugs Other causes for dizzy sensations such as floating or heavy-headedness include: • Anxiety disorders • Low iron levels (anemia) • Low blood sugar (hypoglycaemia) • Ear infections • Overheating and dehydration • Chronic subjective dizziness Symptoms Dizziness can be more specifically described as one of the following sensations: • Loss of balance or unsteadiness • Light-headedness or feeling of near fainting • False sense of motion or spinning (vertigo) If you experience dizziness, consider these tips: • Stand up slowly • Avoid moving suddenly • Sit or lie down immediately whenever you feel dizzy • Avoid driving or operating any heavy machinery if you experience frequent dizziness • Avoid using alcohol, tobacco, and caffeine. Excessive use of these can worsen your signs and symptoms. "Please contact your doctor if you experience any unexplained, recurrent, or severe dizziness"
