What are the most common symptoms of diabetes?

The common and early symptoms of diabetes result from the  effect of the high blood sugar entering the urine and drawing fluid from the bodys tissues along with it. This leads to excess urine production with fre- quent urination. The loss of body fluid leads to thirst, in order to replace the fluid loss. As long as the person with diabetes is able to keep pace with his or her thirst by regular fluid intake, he or she will remain relatively well. However, without free access to fluid, which can occur for a variety of reasons, one will become dehy- drated, which leads to dizziness upon standing upright drowsiness, confusion,  and   ultimately  fainting  and unconsciousness. Due to the wasting of calories as glu- cose in the urine, patients will complain of hunger and will usually lose weight if high  blood sugar is very marked. However, it is important  to note that only a minority of people with diabetes will experience these symptoms. Frequently, the degree of high blood sugar is more moderate, with little sugar entering the urine and causing no immediate  symptoms. However, dia- betes of even modest severity can  cause considerable har and   lead  to   serious  chronic   complications. Therefore, it  is important  to  detect diabetes  that is asymptomatic (i.e., without symptoms), which is the reason that  screening programs to detect diabetes in those at highest risk have been developed. If asymptom- atic diabetes is  not  discovered for a sufficiently long period (many months or years), patients may actually present with long-term complications of the previously unrecognized  diabetes, such  as  heart  attack,  stroke, heart failure, neuropathy (nerve damage), nephropathy (kidney damage), or retinopathy (eye damage).
