I'm 17 years old. I have diabetes from past 6 years and I'm using insulin injections from then. Recently I was hospitalized for 13 days due to increased sugar and ketone level which happened due to fever, cough and vomiting, and resulted in dehydration in my whole body and was barely left with some water in body. Then doctors treated me and I'm quite well from that condition. From then I have continuous cold with phlegm. It's been almost 25 days from then. The phlegm is of yellow colour but sometimes I get brown/red colour of phlegm. I am also taking doctors prescribed medicines from past 15 days. The coughing has decreased alot but not the phlegm. Now I'm very conscious about my condition. I just wanted to know if there is any other risk like TB or something serious. If yes please let me know what precautions can I take. Thanking you.
