For BP this will mean regular exercise (daily), weight normalization if you are overweight,
and eating an unprocessed low carb, moderate protein and high (healthy) fats diet. Medication should be used if lifestyle measures alone cannot control the bp.
For diabetes, it is critical that you keep your blood sugars as close to normal as possible. Normal is Hba1c of < 5.0, fasting blood sugar in the 80s, and post eating blood sugars not higher than 120.
