I have diabetes or not ??

Hi, I'm 18 years old.For a few weeks I notice that I have thick and white saliva ... In August (fearing it) I did some analysis to measure my sugar in case I had diabetes, although no one from my family and others have it.I did the analyzes and gave me that I have 73 glucose or normal ... the truth is that I am worried ... I have a pelin of overweight and I do not exercise much to say, I do not drink much water but this has always happened to me... I notice that I am almost always hungry and that when I drink water I want more water ... I would appreciate them to help me ... what could happen to me?

Well, for what you tell us, you don't seem that you have diabetes or anything.

If you want to stay calm, go to make you a check, although my opinion is that you are healthy but, if you move little, boredom can make you think strange things.
I recommend that you go a little and do some exercise: there are very funny, such as dancing, for example.

Health and welcome.
