These drugs work well in lowering blood glucose levels but also run a risk of a person developing hypoglycemia. Hypoglycemia is when the blood sugar level is too low. Because of this potentially dangerous side effect, sulfonylureas are often given with other drugs, most notably Glucophage, or more commonly known as Metformin. These substances stay within their system and enter the blood stream. The high amounts of sugars in their blood, also called glucose, is called glycemia. Glycemia is a condition when someone has an elevated amount of blood glucose. This is often determined by a blood test. People with diabetes have monitors and are supposed to test their blood glucose levels periodically throughout the day to monitor for glycemia. Therefore, those who have pre diabetes can stave off the disease by making some healthy life choices that will eliminate their need for medication or insulin in later years. One way to reverse the effects of pre diabetes is to maintain a healthy weight. This can be easily accomplished through diet and exercise. Certain signs of diabetes include frequent urination, increased thirst and desire for fluids and may also include an increased appetite. In many cases, a person with Type II diabetes feels generally unwell but cannot figure out what is wrong. Symptoms can mirror the flu or other illnesses. If you are experiencing frequent thirst, excessive urination and a substantially increased appetite, have yourself checked out for diabetes. By understanding he ratings of these carbohydrates, a diabetic can be educated to know the effect of the glycemic index on the body. Years ago, people with diabetes would simply be told to avoid carbohydrates. It was not until 1981 when the medical community began rating different carbohydrates as to their impact on the system. This concept was developed to help people who wanted to rank carbohydrates based upon how they affected the blood glucose levels. Different carbohydrates are absorbed into the system in different manners and all take different times to break down and digest. Carbohydrates that break down and cause rapid digestion tend to leave the most glucose in the blood stream and cause the most damage to a person who is a diabetic.
