The length of time a low platelet of 6×10^9/L can live depends mainly on the severity of the primary disease and whether the treatment is timely, and cannot be generalized. The normal value of platelets is (125-350)×10^9/L. Platelets as low as 6×10^9/L are already at a very dangerous level, and the patient may have skin and organ bleeding at any time. By actively cooperating with treatment, thrombocytopenia has the possibility of cure, then it does not affect life. However, if there is a combination of internal bleeding and other conditions, such as liver bleeding, spleen bleeding, or even intestinal bleeding, it may lead to the patient’s death. For this condition, patients should be treated as early as possible, and if necessary, platelets can be directly injected, which can effectively prevent hemorrhage. Therefore, if the patient actively looks for the cause of the disease and treats it symptomatically, the survival period can be effectively prolonged, but if the patient does not receive timely treatment, he may die after weeks or months. In addition to timely hospitalization, patients need to rest in bed, reduce activities, eat more fruits and vegetables to replenish body vitamins, and avoid eating cold, greasy food; they also need to avoid trauma, as platelets are in the single digits and wounds are difficult to heal, which is more dangerous.
