MNT Goals
 Achieve and maintain:
• BGL in the normal or safe.
• Lipid profile that reduces CVD risk.
• BP normal or safe.
 To maintain good nutritional status, slow
progression, and to treat complications.
 To achieve weight loss in overweight or obese states.
 To Enhance health through food choices and physical
activity.

Editor's Notes

  • #4  One of the main long-term specific microvascular complications of DM People with diabetes and kidney disease do worse overall than people with kidney disease alone. This is because people with diabetes tend to have other long-standing medical conditions, like high blood pressure, high cholesterol, and blood vessel disease (atherosclerosis). People with diabetes also are more likely to have other kidney-related problems, such as bladder infections and nerve damage to the bladder.
  • #12 Major therapeutic interventions include-
  • #14 Glycemic control has been shown to delay the progression of diabetic nephropathy. ADA recommendations state that adults with diabetes should strive to maintain an A1C of <7.0%, preprandial plasma glucose of 90-130 mg/dl (5.0-7.2 mmol/L), and peak postprandial plasma glucose of <180 mg/dl (<10.0 mmol/L). Components of a successful glycemic control plan include: self-monitoring of blood glucose (SMBG), performing an A1C test at least two times each year for patients who meet treatment goals and quarterly in patients who do not, and individualized medical nutrition therapy (MNT). The UKPDS, DCCT, and Minnesota Medical school Trial have shown that intensive management of blood glucose can be helpful to patients in preventing the progression to kidney disease.

  • #21 If early intervention done, progression can be delayed.
