You may alter your lifestyle to help prevent type 2 diabetes by adopting healthier eating habits, engaging in more physical exercise, and decreasing extra weight. When dietary and lifestyle modifications are insufficient, oral medication is a treatment option. Diabetes type one is a lifelong illness that will be carefully monitored. You will need to regularly use insulin and check your blood sugar throughout the day. Untreated diabetes can lead to heart attack, stroke, blindness, kidney failure, loss of toes, feet, or legs, and even death.
