Hi Thanks for posting your query on HCM Sorry to hear your husband has balance issues Balance problems in your husband may be caused by many medical conditions.Some possible causes may include: -Benign paroxysmal positional vertigo -Meniere s disease -Migraine -Acoustic neuroma -Vestibular neuritis -Persistent postural-perceptual dizziness -Orthostatic hypotension -Cardiovascular disease -peripheral neuropathy -Medications -Certain neurologic conditions like Parkinson s disease -Ionic imbalances -And others I will suggest you see the Doctor for examination and investigation.Tests that may help identify the cause of his problem may include: full blood count, ESR, fasting blood sugar, serum electrolytes, brain scan, ECG and others depending on the diagnostic orientation of the Doctor.In the meantime, i will advise you try the following: *Balance retraining exercises *Healthy diet/lifestyle *If symptoms too severe,your Doctor may prescribe antivertigo medications like tanganil while waiting for results of tests. Hope this will help Best regards
