I have had positive experiences with drinking electrolyte (salt) drinks at least a litre a day. A recipe for a cheap homemade version without the added sugar is available online but I must admit I have enjoyed Staminade Blue, Gatorade and Powerade powder mixes and I do believe they help when I have a tendancy towards one kind of dizziness that I experience. Intravenous (IV) Saline takes the idea one step further and this helps treat an often unrecognized condition called POTS - Postural Orthostatic Tachycardia Syndrome. The effects of intravenous saline are more immediate than drinking sports drinks throughout the day so it is important to have a little background knowledge especially with regard to the blood-pressure boosting effects of salt protocols. This can be a good thing for people with predominantly low blood pressure but obviously it will not suit someone with high blood pressure.
It is interesting to note that Dr David Bell, the treating doctor at the Lyndonville ME/CFS outbreak, also inadvertently discovered that IV Saline treatment was helping many patients. Some of his patients were receiving intravenous vitamins and gammaglobulin in a saline base and the positive outcomes were not immediately attributed to the saline component because it was the norm to consider a saline drip as placebo in medical trials. At the time of reporting his findings, Dr Bell did not think he was witnessing a placebo response and he stated that he had found the most effective treatment for severe ME/CFS in 21 years of looking. It is important to note that PICC line infections are a risk factor during intravenous therapy and that the effects of saline treatment are only temporary and not a cure. Therefore it becomes an ongoing treatment every few days and once the treatment is stopped, so too do the symptoms of orthostatic intolerance return.
