This is more of a strategy than a treatment.

In Watchful Waiting you have a relatively safe count that protects you from life-threatening bleeding, you understand the pros and cons of the treatment options, you understand the risks of having a low platelet count, you understand your body and how it reacts to stress and other potentially platelet-lowering situations, you have a way to periodically monitor your platelet counts, and you have a plan in place if your symptoms get worse.

Then you decide to live with your ITP while carefully monitoring your disease.
