Measure the levels of sugar in the blood is one way to measure how the body uses glucose, a sugar that is the main energy source for cells. After a meal, the level of glucose in the blood rises. A hormone called insulin helps transport sugar into cells, where it can be used as a food substance. The level of blood sugar then drops to normal.
The levels of sugar in the blood that remains higher than normal are indicative of two problems: (1) cells need nutrition because they are not absorbing enough glucose and (2) extra sugar circulating in the blood can damage the eyes, kidneys, nerves, heart and blood vessels.
These three factors must be balanced. If any of these is off, so will the concentration of blood sugar. Generally, excess blood sugar may be caused by:
• Take medications for diabetes when they should be taking or not taking the proper amount. • Not following the diet plan for diabetes (such as overeating on a special occasion without adjusting the dosage of medicines for diabetes) • Not exercising enough • Have an illness like the flu, or stress • Take any other medications that affect how the medications for diabetes.
New guidelines (2004) define two categories of blood sugar higher than normal:
The level of blood sugar is high but not high enough to qualify as diabetes. The formal terms of this condition are those of "impaired glucose tolerance" and depending on how far the blood sugar. People with pre-diabetes are at greater risk of developing cardiovascular disease or diabetes in the future.
Diabetes: - There are two main types:
• Type 1, in which specific cells of the pancreas loses its ability to produce insulin. Type 1 diabetes is relatively rare and usually occurs in children and young adults. • Type 2, in which cells throughout the body lose their ability to respond to insulin.
Between 90-95 percent of people with diabetes have Type 2 variety? The risk for Type 2 diabetes increases with age, although it is most often diagnosed in all age groups. Other risk factors for Type 2 diabetes include being overweight, lack of exercise, high blood pressure, family history of diabetes and being African American, Latino, Native American or Asian-Pacific Islander.
Experts estimate that nearly half of people with Type 2 diabetes living in the United States, or about 8 million people, have not been diagnosed. Although the early stages of Type 2 diabetes have few symptoms, may be causing damage to the eyes, kidneys, blood vessels and nerves. Further studies of diabetes associated with an increased risk of mental decline and dementia.
The Diabetes Prevention Program, a nationwide clinical trial that consisted of 3234 participants (including 45 percent of high-risk ethnic groups), found that overweight people with pre-diabetes can reduce their risk of developing diabetes 58 per cent (71 per cent for participants over 60 years of age) through the following actions:
• Losing between 5 and 7 percent of their body weight (10 to 15 pounds in a person with 200 pounds) • Making physical activity or other exercise moderately for 30 minutes, five days a week • Following a healthy diet, low fat
