Colds generally do not cause thrombocytopenia, there is no direct link between the two. Colds are common diseases, the main type is due to decreased resistance and invasion of pathogens leading to upper respiratory tract infections, these pathogens include viruses, bacteria, mycoplasma, chlamydia, rickettsia, etc. While thrombocytopenia can affect the patient’s coagulation function, if there is more obvious thrombocytopenia, the patient should seek medical attention to limit the further development of the disease. Patients should get more rest, cooperate with doctors, not eat greasy and spicy food, and eat more fruits and vegetables.
