Overview
Dizziness is one of the most common complaints in medical practice and can have very different causes. Many people describe a spinning sensation as if on a carousel, a swaying feeling as if on a boat, or unspecific light-headedness. In most cases the cause is benign – particularly often benign paroxysmal positional vertigo, in which brief attacks of spinning dizziness are triggered by changes in head position. In an OpenClinic24 video consultation, a doctor takes a structured medical history: the type of dizziness, its triggers, the duration of the attacks, accompanying symptoms such as hearing problems or tinnitus, and possible warning signs. On this basis it is often possible to assess whether a benign condition is likely or whether a prompt in-person visit to a practice or hospital is needed. Following the doctor's assessment, treatment recommendations can be given, repositioning exercises demonstrated or – where medically appropriate – a private prescription issued in accordance with the German medical fee schedule (GOÄ).
Common causes
The most common cause of brief attacks of spinning dizziness triggered by head movements is benign positional vertigo: small calcium crystals move into the semicircular canals of the inner ear and irritate the balance organ. Longer-lasting spinning dizziness with nausea can indicate inflammation of the vestibular nerve (vestibular neuritis). Attack-like dizziness with ear pressure, tinnitus and hearing loss is typical of Menière's disease. Migraine can also cause episodes of dizziness (vestibular migraine). In addition, circulatory causes may be involved, such as blood pressure fluctuations when standing up, fluid deficiency or side effects of medication. Swaying dizziness and light-headedness also occur with neck muscle tension, anxiety disorders or, in older age, through the interplay of several factors. Less commonly, serious neurological causes such as impaired blood flow to the brain are responsible – their warning signs are checked systematically during the video consultation.
When to see a doctor
Seek medical advice if dizziness occurs for the first time, keeps returning, lasts longer than a few days or restricts your everyday life. Prompt evaluation is also advisable for dizziness with hearing loss or tinnitus, after a fall, or after starting new medication. Call the emergency number 112 if dizziness occurs suddenly together with one or more of the following warning signs: paralysis or numbness in the face, arm or leg, speech or swallowing problems, double vision or loss of vision, the worst first-ever headache, impaired consciousness, complete inability to walk, or dizziness after an accident involving the head. These signs can indicate a stroke or another life-threatening cause and do not belong in a video consultation. In all other cases, the structured video history can help classify the dizziness and agree the next steps together.
