As the depression continues, people often lose interest in monitoring their blood sugar levels and may even skip their medication. Symptoms of depression include a loss of pleasure in every day activities you used to enjoy as well as a change in appetite. You may have trouble concentrating and have trouble sleeping. Tiny blood vessels make up the retina and too much blood glucose cause these vessels to swell. They gradually begin to weaken and the person begins to experience vision problems. For this reason, a person with diabetes should have an eye exam once a year. During the exam, the eyes should be dilated to see if the condition has become worse. The only vegetable that a diabetic should avoid is a potato, as it has a high glycemic index. Other fruits and vegetables, however, are preferable than white rice, white bread, corn flakes and anything made with white refined sugar or flour. Other good glycemic foods include wholegrain breads and pastas. This is why it is so important for an individual to carefully monitor their blood glucose level throughout the day and keep a record for the physician. By working with your physician and reporting symptoms and results of blood glucose monitoring, you can empower yourself to keep your diabetes in check and avoid any complications that are associated with this disease. According to the American Diabetes Association, approximately 54 million people in the United States have pre diabetes. Pre diabetes is a condition in which the blood glucose levels are higher than normal but not high enough to be considered Type II diabetes. Although pre diabetes is not a full fledged disease, it can also cause complications in the heart and blood circulation if left untreated. People with Type II diabetes do not process enough insulin to break down the glucose in their system and cause their kidneys to work overtime in getting rid of the waste. While some people with Type II diabetes are prescribed insulin, most are started on a regiment of medication. Physicians generally hope that by taking medication as prescribed, exercising, eating the right foods and monitoring their blood glucose levels, they can avoid the use of insulin.
