<s>[INST] Hello doctor, my platelet has been progressively decreasing for the last couple of years.Jun 2012 - 157 x10^9 Aug 2013 - 160 Aug 2014 - 143 Feb 2015 - 125 Apr 2015 - 111 All other counts on the CBC has been normal except for Basophils (0.1) in the last test (in previous tests always (0.0).My GP had no idea why my platelet count is decreasing. Two months ago, I was found positive for helicobacter pylori and was treated with antibiotic therapy Nexium7 for a week. Haven t been tested again to confirm if it has been cured. At the same time I was viral labyrinthytis when I started to feel vertigo. I am going to see a haematologist soon. I just wanted to know the possible reason for my progressively low platelet count. Should I be concerned? Does the H.Pylori infection or the Labyrinthytis has any role in low count of platelets?Thank you. [/INST] I have reviewed your concern my friend. You are doing right thing by going to hematologist. However, decreasing platelet count can be due to different causes. H pylori and labyrinthine should not ideally cause this problem, but it can be more due to a condition known as idiopathic thrombocytopenic purpura (ITP). However, for this the hematologist needs to review your condition and probably do a bone marrow examination if required and rule out other cause. Treatment is steroids which is generally good enough. I hope this helps. Let me know if I can help you in another way thank you for choosing Chat Doctor. May you have a super healthy life ahead. </s>
