If you feel the sensation to pass urine frequently, you may be affected by diabetes. Here is the explanation of why such a sensation occurs - when the sugar level in the blood increases, it causes an increase in the osmolality of the liquids in the blood circulation. This increase in osmolality exerts a pressure on the kidneys to generate excess urine. Because of this, the diabetics get the sensation for the frequent passing of urine.
The diabetics always have a feeling of total thirst for water. This is because most of the liquids in the body circulation get drained as explained above with the tendency to frequent passing of urine.
Thus the symptoms of the sensation for frequent urine passing and the feeling of persistent great thirst.
Further, the liquids released from the blood due to the excess glucose in the blood will deteriorate the eyesight. It will also affect the ability to have a sharply focused look with both the eyes. In case a proper medical care is not taken, it will reduce the eye-sight. Further, it may even lead to loss of vision sometimes.
This symptom is typical for the patients affected with Type-1 diabetes. As the live cells are deprived of the requisite glucose, the body will take up the task of getting this requisite energy from the fat-rich food taken. This will lead to loss of weight.
The body of the diabetic will not be able to absorb the energy required from the sugar level in the body. So, the patient tends to get affected by fatigue and tiredness, etc. Without the availability of insulin, the live cells in the body will not be able to absorb the glucose available in the blood circulation system. Thus, the capacity and functioning of the cells will be reduced to a lower level.
As the sugar level in the blood goes up, the nervous system especially tends to get affected. In the case of diabetes remains undetected for a long duration, it will lead to some throbbing sensation in the hands.
