You may discover you have diabetes mellitus from some early symptoms of the disease if you recognize the symptoms. The Mayo Clinic reports diabetes mellitus is a term for several conditions in which your body has problems using glucose. Type I diabetes usually develops early. The body cannot produce insulin, a substance needed to balance the body's sugar levels. Type II diabetes usually happens later in life, when your body develops an imbalance of insulin and glucose. Gestational diabetes typically is temporary during pregnancy.
Thirst and Hunger
Diabetes prevents the body from effectively using the glucose that comes from the food and beverages you consume. Much of the nutritional value of food and drink may be lost. As a result, you body will flush out liquid you need through urination. This can cause you to be excessively thirsty. No matter how much liquid you drink, you may not be able to satisfy your thirst. You also may find you are excessively hungry, even after you have eaten. You may suddenly need to eat a lot more than you normally do. This, again, is related to the nutrients not being absorbed into your body. Your body responds to this by craving more food. Despite eating significantly more than you usually do, you may find you are losing weight.
Frequent Urination
Diabetes causes your system to flush out much of what you take in, both in food and drink. This means that whatever you drink will go through your urinary tract much more quickly than usual. You may find yourself urinating much more often than you normally did before the onset of the disease, the Mayo Clinic reports.
Vision Problems
Most changes in your vision occur gradually unless there is some trauma or disease at work in your body. If you suddenly have changes in how you see, particularly if your vision suddenly becomes blurry, you may be experiencing an early symptom of diabetes Type I or Type II, according to the Centers for Disease Control and Prevention (CDC).
Fatigue and Numbness
Without the proper nutrients, you do not have your usual level of strength. This can result in excessive tiredness, according to the CDC. You also may feel numbing or tingling in your feet and hands as a result of the onset of diabetes mellitus.
Sores and Infections
One of the early tell-tale signs of diabetes is a problem with your immune system. While this can be related to many diseases and even medications, certain signs may indicate diabetes. For example, if you get infections more frequently than you have in the past, it could mean diabetes is at work.
