I wonder if all my symptoms i have felt actually can be diabetes?

Depends: Since you didn't report what symptoms you are experiencing, it would be difficult to say. Classic symptoms for diabetes includes: increased thirst increased hunger increased urination unusual weight loss here's a helpful link: http://www.Diabetes.Org/diabetes-basics/symptoms/.

Maybe: Diabetes can affect all the organs of the body- so , yes but, most of time , other things going on can or are causing similar symptoms ie: symtoms not rel;ated to dm it's why , as a diabetes specialist, i insist on keeping my skills in general medicine so, must see a quality internist, or endocrinologist who will take care of whole patient to decide what a particular symptom is caused by.
