Hi,
i think that hypoglycemia has many causes. Some people are just born with a tendancy towards handling sugar and carbs in a way that causes their pancreas to release too much insulin. Others develop the condition by eating an unhealthy diet of too much sugar etc. Also I feel that hormones can upset the balance in the body and cause hypoglycemia.
I know mine has been much worse since menopause. That causes so many symptoms and one of them is hypoglycemia. I think that a healthy diet can help many health problems, so there is hope.
I hate to sound cynical but I think the reason there has been so much research on diabetes is that there are so many medications that have been developed to control it ($$$) not so with hypoglycemia. I do think it can lead to diabetes in many people, but if you're careful you can keep that from happening.
Being overweight can be a result of hypoglycemia because the body handles carb and sugar differently. I know I have a tendancy to overeat to keep my blood sugar up which cause weight gain also so I have to be very careful. It's not easy.
Hope this helps.
