For Type 1 and Type 2 diabetes, there are many signs in common. Fatigue is one cause for worry. Fatigue indicates that the body is not using glucose for fuel efficiently. The body will switch over to burning the fat in the body as its fuel source. This causes the body to use more energy and the result is continuous tiredness.

If you experience unexplained weight loss, even though you are eating the right amounts of food, and even more, you may not be processing the calories. You are also losing sugar and water by frequent urination. Dehydration also leads to weight loss. Excessive thirst occurs when there are high blood sugar levels in the blood. It signals the brain there is too much sugar in the blood and the body tries to dilute it. This will make you constantly feel thirsty.


Another way to rid the body of excess blood sugar is through frequent urination. Sugar carries water with it as it is flushed out of the body. The body gets confused and tries to produce more insulin when the body has become resistant to it. When the body has high insulin levels, the body thinks it needs to stimulate hunger. You may be eating more, but not gaining weight, and could even lose weight.

A wound not healing in the proper time is another sign you should be concerned about high blood sugar levels. The high sugar levels prevent white cells from functioning properly. White blood cells fight bacteria and clean up dead tissue and cells. When the white blood cells are not working properly, it takes wounds longer to heal and there is more of a chance of infection in the wound.


Frequent infections also may be a sign of poor blood sugar control. Yeast infections, skin infections, and urinary infections appear because sugar levels in the blood allow infections to attack and grow. If these infections often show up, it should send a signal to contact your doctor, especially if you have been diagnosed as prediabetes.

If you experience weakened or blurry vision, you should have your blood sugar levels checked. This isnt a symptom of diabetes alone, but is widely known as a symptom of high blood sugar levels.

Mental States

One of the scariest diabetes symptoms could be how it affects your mental status. Agitation, inability to pay attention, increased irritability, confusion, and high sugar levels could explain inactivity and the previously listed symptoms. I watched my Dad go through times of extreme agitation and irritability, usually caused because he wasnt doing what he was supposed to do to control his sugar levels. If your loved one or family member has changed for some unknown reason, you may want to contact your doctor and take them to be checked.

Symptoms of diabetes are different with each person. If someone is experiencing any of the listed problems, your doctor may want you to have a blood sugar test before the doctor appointment.
