<s>[INST] My relative who is 24 years of age has dengue fever, his platelet count has dropped to 0000 and also has diabetes. His grandparents have diabetes, parents do not have. what diet do you recommend for this scenario.His before food sugar level is 140 and after food is 200. He has been undergoing treatment for the last 7 days and when he was admitted his platelet count was 0000. [/INST] Hello, Thanks for the query to Chat Doctor. Forum. Without knowing the exact value of platelets it is very difficult to evaluate any diagnosis. As I have seen so many cases where platelets fall below 8000 and there were no any complaint. This type of cases known as thrombocytopenia and cause may be else. 2nd point is diet of diabetes, so mention the type of diabetes, H B A 1 C value, condition of pancreas. As you mentioned that his blood sugar level is 200 mg /DL after food, 140 mg/ DL before food. This sugar level is not so high, so in my opinion only diet plan can cure this patient. Virology test prove whether patient have dengue or not. Consult a physician and get his opinion and treatment. Good luck.  </s>
