What should you know about Meniere's disease and potassium?

Meniere's disease affects the inner ear and can cause episodes of vertigo, ringing in the ears, ear pressure and hearing changes. Potassium helps the body use nerves and muscles, but a blood potassium result is not a diagnosis of Meniere's disease. Low or high potassium can occur for several medical reasons, including illness or medicines, and may cause symptoms such as weakness or an irregular heartbeat.

Dietary changes promoted for Meniere's disease often focus on steady routines and limiting personal triggers. Do not assume that adding potassium-rich foods or taking a supplement will control ear symptoms.

Tell your GP about every medicine, supplement and salt substitute you use. Ask whether a blood test is appropriate before changing potassium. Record vertigo, ringing, hearing changes, meals and medicines in a symptom diary; this can reveal timing without claiming a single trigger. Arrange a GP consultation for recurring attacks or ongoing hearing loss. A hearing test helps document hearing function and supports referral decisions.

Never stop a prescribed medicine or begin a mineral supplement because of an online suggestion. People with kidney or heart problems may need particularly careful advice about potassium.

Seek urgent help for palpitations, fainting, marked weakness, difficulty breathing, sudden hearing loss, or vertigo with new weakness, facial drooping or trouble speaking. During a severe spinning episode, sit or lie somewhere safe and avoid driving until symptoms have settled and you have been assessed when needed.

Could any of my medicines affect potassium or dizziness? Do I need a blood test? Which dietary changes are reasonable for me, and when should I arrange a hearing test?
