Hello, I m afraid I ll have to disagree with your doctor. I believe you need treatment for your cholesterol. Your LDL levels (although not mentioned) should be really high even for a patient without diabetes. Diabetic patients should have a more strict cholesterol regulation according to current guidelines because their risk for cardiovascular and other complications is high. I would suggest sticking to a healthy diet, maintaining a healthy body weight and getting some exercise every day to the extent that other possible medical issues allow for. If you re a smoker try to cut down on smoking. I usually advice my patients to try atorvastatin 20mg once every night, if no contraindications exist. This can prove enough to reduce your LDL levels to a more acceptable range. A final word of caution: since I ve only read the rather short paragraph you wrote, which does not include enough information for a complete evaluation, perhaps your first step should be to ask your doctor why he hasn t prescribed any medication for your cholesterol despite its high levels. You can ask me again if you d like providing more information about your health, including kidney and liver functionality, other medical issues, other drugs etc Kind Regards!
