Hi there! I was going to tell you that I suffer from severe electrolyte imbalances as well. I have also been diagnosed with reactive hypoglycemia and tested for adrenal insufficiency.
I know this can be very frustrating and confusing to manage, especially if you aren't sure what exactly is causing it and the symptoms tend to be inconsistent.
The biggest thing I had to learn to do throughout my ordeal was learning how to listen to my body. Sometimes I CRAVE salt. Literally, I will eat it right out of the shaker, and other times I will have something a small bit salty and I feel terrible and my blood pressure goes nuts and my heart rate climbs. It can be very scary and frustrating. My doctors and nutritionists finally worked out a lenient meal plan that I can loosely follow to help try to balance everything out.
Basically I am suppose to eat more protein than simple carbs, to keep my blood sugars from spiking and crashing. I am also not allowed potassium, as there seems to be an overabundance of that in my system already. Also, I was instructed to not drink more than 64 ounces of water a day.
