As many people who have MD know salt is supposed to be reduced greatly in their diet. It has been recommended by some that your sodium intake is to be limited to 1000 mg a day. Considering all the salt in prepackaged food, including canned food and the food that they serve at restaurants it can be very difficult to keep it at that level. It might be more realistic at 2000 mg a day.
But why is salt such a culprit? There is endolymphatic fluid in the inner ear that has a specific amount of sodium, potassium, and chloride. This balance of these fluids keeps the inner ear functioning as the central balance system of the body. Any interruption of that balance causes the symptoms of Hydrops which is pressure in the ears. It may also cause tinnitus, hearing loss, and dizziness.
Salt in a diet helps to retain water. So naturally the reduction of salt and possibly a diuretic can help lower the amount of fluid in the inner ear. A low salt diet is referred to has a hydrops diet regimen.
