My blood platelets are 75000, what should i do to increase platelets as soon as possible?

Itp: Nothing, just have them check again in 2 weeks. If they drop below 50, 000, i would recommend therapy, not now.

Closely watch...: Low platelets can be due to destruction or a problem with production. Treatments for low platelets depends entirely on the cause. Sometimes merely watching and waiting will resolve the problem. There is usually nothing you can do (for example, diet, supplements, etc.) that will cause the low platelets to rise.
