Diabetes that requires insulin to control is different than those who rely on diet and exercise and I am not experienced to know about all the details with insulin use. I know it is used when the pancreas is not doing its job and the situation is serious. Type 2 diabetes without high blood sugar numbers can concentrate on diet and exercise and not have to be concerned with hypoglycemia unless they are living with stress or taking meds that raise the blood sugar, How well the pancreas and thyroid work is another factor and is an individual matter as people are different. A well balanced diet with every meal and regular meal times provides good control but many of us prefer a quick fix which meds can provide. The problem is that wit meds we must be careful that the blood sugar does not drop too lowand cause an emergency. My friend at work went home hungry, put water on the stove to cook, was alone and dropped over unconscious and his wife found him but it was too late to save him. So eating often can be a factor if you work hard and don't eat. Listen to your body.
Some of the meds advertised warn against low blood sugar. One ad says not to use if your have had thyroid cancer, which I have had and my thyroid was removed. Now I drag around tired from that as well as diabetes issues. My back surgery has resulted in not being able to exercise enough for good blood sugar control. So it is diet control that provides good results.
My cousin, who is younger than I, uses a once a week shot of something. It works for her. She walks every day. Dorisena
