Meniere's syndrome is defined clinically by the combination of vertigo, tinnitus (ringing in the ear), and some loss of hearing during an attack. People may also experience pressure in the affected ear, and the vertigo can be accompanied by severe nausea and vomiting. The attacks typically come on abruptly and last for at least several hours. The frequency, severity, and duration of attacks can be highly variable.
The exact cause of Meniere's is unknown. The leading theory suggests the symptoms are related to an increase in the amount of fluid (endolymph) within special canals in the inner ear called labyrinths. Thus, the other name for Meniere's is endolymphatic hydrops.
There is no known link between high blood pressure and Meniere's. I can see why someone might see how the two conditions might be related. In both, the pressure of fluid inside channels increases. With hypertension the increased pressure is inside the arteries, and with Meniere's the higher pressure occurs in the labyrinths.
Some of the advice for people with Meniere's is similar to the advice given to people with high blood pressure. Some people experience fewer attacks with less severity by decreasing dietary salt and limiting alcohol and caffeine. Stress reduction and quitting smoking may also help. Since these recommendations are good for general health, it is reasonable to try them. But the evidence that any one of these changes will make a big difference is not definitive.
