Diet

Eat frequent small meals instead of 3 meals per day (causes less blood flow and pooling in abdomen during digestion).
Increase fluid intake to at least 64 ounces a day including water, electrolyte sports drinks, V8/ tomato juice, coconut water, etc... Recommend not leaving home without a water bottle.
Increase salt (sodium) intake to 3-10 grams per day. Eat or drink high sodium products and/or take salt tabs (i.e. Saltstick).
Avoid any possible dietary triggers that worsen symptoms. Common ones include gluten, dairy, and processed carbohydrates.
Avoid alcohol as it causes vasodilation (widening of blood vessels) and dehydration.
Monitor caffeine intake. Some patients find it helps due to it's stimulative effects, others report worsening of symptoms.
