It could be the combination of all the supplements and the ab/cardio workout. Dandelion root is a natural diuretic, you could be depleting nutrients too fast (e.g. iron, potassium), I'd reduce or stop everything until it clears up. Too much too fast can back fire, your system is just reacting (return to hemeostasis) to the new extreme.

Seeing a doc is definitely a good idea regardless.
