I dont know about in terms of having diabetes in addition to a low platelet count but I have knowen two individuals with dangeriously low Plat counts. The first thing they did was test foe illnesses when that didnt find a thing they started pulling off all medications that where not deemed necessary and changing those that where. Basically they did not treat or change anything but eliminated and where afriad to do anything in case the body had a worse reaction. One person was advised they could bump somthing and bruise then bleed to death they where so bad. Long story short the med tweaking etc seemed to work apparently the body reacted badly to external factors being introduced (medications).
