Electrolytes 101: Why They Matter for POTS and Chronic Illness
If you live with POTS (Postural Orthostatic Tachycardia Syndrome) or another form of dysautonomia, you probably already know hydration is important. But staying hydrated isn’t just about drinking water—it’s about maintaining a delicate balance of electrolytes. These tiny minerals play a massive role in how your body functions, especially when you have a chronic illness that affects your autonomic nervous system.
We’re breaking down what electrolytes actually do, why an electrolyte imbalance can be so dangerous, and how to get hydration right.
What Are Electrolytes and Why Do They Matter?
Electrolytes are minerals that carry an electrical charge. They include:
-
Sodium
-
Potassium
-
Magnesium
-
Calcium
-
Chloride
-
Phosphate
-
Bicarbonate
These minerals regulate fluid balance, nerve signals, and muscle function. They keep your heart beating properly and help your body absorb fluids efficiently.
For people with POTS, sodium is particularly important because it helps increase blood volume and reduce symptoms like dizziness and rapid heart rate.
Electrolyte Imbalance and Chronic Illness
Many people with chronic illnesses like POTS, ME/CFS, or Ehlers-Danlos Syndrome report challenges with maintaining electrolyte balance. Dehydration, heat intolerance, medications, and excessive sweating may contribute to this, and some individuals find that addressing electrolyte intake helps them feel more stable.
Common symptoms of electrolyte imbalance:
-
Dizziness or lightheadedness
-
Fatigue
-
Headaches
-
Brain fog
-
Muscle cramps
-
Heart palpitations

Not All Electrolyte Drinks Are Created Equal
Sports drinks might seem like a no-brainer for hydration needs, but they often include lots of added sugar, dyes, or artificial sweeteners, which some people choose to avoid based on personal sensitivities or dietary goals. In addition, a 20oz sports drink may only contain 250-300 mg sodium.
Oral Rehydration Salts (ORS) are globally recognized for their effective hydration support, especially in situations where water alone may not be enough. The World Health Organization recommends a precise formula for ORS containing sodium, glucose, and potassium that helps your body absorb water directly into your bloodstream.
