Towards the end, waste products begin to build up into the blood. This is the basics of kidney disease. Kidney disease is acquired in many ways. In diabetics, it is acquired because the kidneys worked too hard to filter out the sugars and starches and were unable to remove waste products from the blood. Onset is the time it takes for the drug to reach the bloodstream and begin lowering the glucose. The peaktime is the time when the drug is at the maximum strength and the duration is how long the drug continues to work in reducing the blood glucose level. Each patient has different needs when it comes to insulin and for this reason, there are many different types of the drug. Some of the signs of retina damage from diabetes include blurry vision, flashing lights, dark spots in front of the eyes, pain in the eyes, or pressure and trouble with peripheral vision. If you have been diagnosed with diabetes and are experiencing any of these problems, see your ophthalmologist for a complete eye exam. Smoking also contributes to tooth and gum problems. But the diabetic has more of a chance of developing tooth and gum disease than the average person. If a diabetic allows his or her blood glucose level to remain high, it has a severe impact on their teeth. This is particularly true if the person with diabetes is older than 45, an age when many people begin experiencing problems with their teeth. 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. Avoid foods that are high in starch and sugars. The Glycemic Index is an excellent tool that can inform a diabetic about which foods should be avoided. Maintain your weight and exercise regularly. This will also boost your immune system. Be sure to visit your doctor regularly and monitor your blood glucose level.
