High blood glucose sets up a domino effect of sorts within your body. High blood sugar leads to increased production of urine and the need to urinate more often. Frequent urination causes you to lose a lot of fluid and become dehydrated. Consequently, you develop a dry mouth and feel thirsty more often. If you notice that you are drinking more than usual, or that your mouth often feels dry and you feel thirsty more often, these could be signs of type 2 diabetes.
Be active every day. Exercise is one of the best ways to keep your blood sugar under control. It also improves blood flow and keeps your heart healthy. The American Diabetes Association recommends 150 minutes of moderate-intensity exercise a week for most adults with diabetes. Also, it suggests taking a break from sitting every 30 minutes to get a few quick bursts of activity. But talk with your doctor or physical therapist first. If you have decreased feeling in your legs, some types of exercise may be safer than others.
Abnormal cholesterol and triglyceride levels. If you have low levels of high-density lipoprotein (HDL), or "good," cholesterol, your risk of type 2 diabetes is higher. Triglycerides are another type of fat carried in the blood. People with high levels of triglycerides have an increased risk of type 2 diabetes. Your doctor can let you know what your cholesterol and triglyceride levels are.
