Hi
@Lynne888 and welcome to the forum.
Constant urination
is a diabetes symptom. Though more so for those whose Blood Glucose readings are very high, unless they have a UTI which themselves are more likely in diabetics with high blood glucose than in the rest of the population.
An HbA1C of 50 is only just above the diagnosis level of 48, so you have a very good chance of being able to reverse it without drugs (if you want to).
But yes, many Diabetics have been put on drugs unnecessarily without first being given the chance to reverse it by lifestyle changes.
Many in the diabetes forums have reversed their Type 2 diabetes by changing what they eat and taking a little more exercise. But that isn't possible if they Type 1 or other less common variety of diabetes. Those who are relatively slim (like me) just reduce the amount of carbohydrates they eat (eating to their Blood Glucose meter) so as not to put too much strain on their pancreas (the insulin producing organ). This isn't just sugars (including fruit juices and tropical fruit), but starchy food as well (such as bread, potato, rice, pasta and many breakfast cereals). This often results in reduced weight and blood pressure (unless more protein (traditional) fat is eaten. So those on blood pressure medication may find they no longer need it.
Type 2's who are more typical (much more overweight) tend to be more equally split between those who choose Low Carb eating and those who choose a very low calorie diet followed by a weight maintenance regime.
Both methods work in most cases, but they have to be maintained - so whichever one you choose, it needs to be something you like and can continue to do. This is a marathon, not a sprint.
