platelet count was 105,000, dr was not concerned?

Hello and welcome to e health forum.

The normal platelet count is 150,000 - 450,000 per cmm. In your case, it seems that your platelet levels are consistently at the lower range, and this may be the normal for you.

For your information, severe bleeding tendency and complications from low platelet counts occur only when the platelet count is very low (less than 20000 platelets /cmm).

There are no specific ways to increase platelet counts, other than platelet transfusions. But such transfusions are done only when the platelet counts are very low (less than 20,000 platelets /cmm).

In case, you do not have any other signs or symptoms other than a slightly lower platelet count, then there is no need to be concerned about. You can take Folic acid and Vitamin B 12 supplements, that may help to some extent to increase the blood cell production in the body.

In case, of doubts you can consult a hematologist, who can do additional tests (peripheral blood smear) and rule out other conditions like renal disorders, blood loss disorders, liver disorders, etc which can be the cause of the reduced cell counts.
