You deserve answers that actually make sense. Eureka is an AI doctor that listens, remembers, and never dismisses your concerns. Built for people who refuse to settle for "just get more sleep" as medical advice.
Key Takeaways
Most balance problems come from one of four areas: the inner ear (vestibular system), the brain and nerves, vision, or the muscles and joints that tell your brain where your body is. Ear crystals that slip out of place, low blood pressure, medication side-effects, nerve damage from diabetes, and small strokes are the five most common culprits doctors see in clinic.
Which body systems keep you steady on your feet?
Balance relies on a constant conversation between the inner ear, eyes, sensory nerves, muscles, joints, and the brain. When any link breaks down, you may feel light-headed, unsteady, or as if the room is spinning. “Think of balance as teamwork—if one player is injured, the whole squad falters,” explains Sina Hartung, MMSC-BMI.
- Inner ear crystals can dislodge (BPPV)Benign paroxysmal positional vertigo happens when calcium crystals wander into the wrong ear canal, causing short bursts of spinning with certain head positions.
- Poor vision removes orientation cuesCataracts or glaucoma reduce visual feedback; over 30 % of adults with severe vision loss report chronic imbalance.
- Peripheral neuropathy blunts foot sensationDiabetic nerve damage makes it hard to sense the ground, doubling fall risk in people over 60.
- Cerebellar disorders slow reflexesMini-strokes, alcohol injury, or multiple sclerosis in the cerebellum delay the split-second corrections needed to stay upright.
- Weak core and leg muscles reduce stabilitySarcopenia (age-related muscle loss) decreases ankle and hip strength; each 10 % drop in quadriceps power raises fall risk by 15 %.
- Sudden blood-pressure drops trigger dizzinessLow blood pressure—such as when you stand up quickly or from certain heart conditions—can cut blood flow to the brain and cause abrupt light-headedness and imbalance. (NIH)
- Joint and skin sensors supply essential position feedbackPressure receptors in your muscles, joints, and skin constantly report body position to the brain; disorders like arthritis or severe foot pain can degrade these signals and undermine stability. (ClevelandClinic)
