Hi there, thanks for asking. That is a good question. One of common reasons for the drop in the potassium level is secretions of fluids from the body. It can occur by perspiration in pneumonia, or secretion of fluid from the lung, nose and other parts of respiratory system. Fortunately, its management is easy especially when the drop is mild (the potassium level is close to 3.5). It is enough to take some foods which have more potassium like banana, tomato, etc. There is no need to worry about it when its level is more than 3. Let me know if you have any other question. I wish you a good health.

Hi again. Most of the time, a brief change in platelet count can happen following infection and is of no clinical significance. If it is really low, it could be a sign if idiopathic trombocytopenic purpura which is a problem which often can happen several weeks after a pneumonia or other infections. And it is accompanied with small colorful spots on skin. Is it so for you?

Hi again. It happens that in the routine blood test, platelet count is reported to be a little low. As you mentioned, I am a Persian physician. I am in Canada.
