Hello, I suppose your diabetes is type 1. You haven t mentioned smoking which is a crucial bit of information. Anyway, a healthy lifestyle includes abstaining from alcohol consumption and smoking, maintaining a healthy body weight and exercising regularly. Since you have some serious cardiovascular conditions, your cardiologist should advice you on the exercise intensity that s safe for you. Walking is great for almost everyone. Try walking every day (or at least every other day) for 30 or more if your cardiologist won t disagree. Alcohol can even help the cardiovascular system in small quantities. Alcohol dependency is another story though. It makes everything worse - your diet, your heart s condition etc. You should contact an experienced doctor on this subject because it s not an easy or safe process to just cut down on drinking. You would require psychological and medicinal support for a long time. The last element of a healthy lifestyle includes a healthy diet. As a diabetic you should always watch the quantity of your food. You should also avoid saturated fat and eat a lot of fiber. Should you need a more detailed approach don t hesitate to ask again! Kind Regards!
