Hypoglycemia does not necessarily lead to diabetes, but it can if not managed. There are three generations of hypoglycemics in my family and only 1 diabetic. It is a good idea to see a doctor, but they often don't recognize hypoglycemia as being a legitimate problem or can't easily test for it.
While you should carry something sweet with you when your sugars drop it is more important to eat properly. I suggest carrying dried apricots rather than sugar because they provide sugar buffered by fiber. Try eating 1/2, not a whole one and really chew it until it practically dissolves. You absorb carbohydrates (sugar) through the mouth. However, simply eating better and more often may eliminate or certainly reduce your problems.
Make sure you get a good breakfast, whole rolled oats with nuts and seeds provides a slow release carbohydrate and protein. Eat snacks every 2-3 hours. Good snacks are vegetables and hummus, nuts, cheese and whole grain crackers. Make sure you get vegetables at every meal. You might try eliminating grains for a while as many hypoglycemics have a hard time with grains. Get good quality protein (fish, poultry, lean beef, pork, tofu). Good vegetables are broccoli, cauliflower, greens (kale, chard, mustard), fennel, beans, carrots, mushrooms. Root vegetables like squash may cause problems.
Add good fats to your diet. Fats help to slow down the absorption of carbohydrates, and it is the carbohydrates that spike the blood sugar. But good carbohydrates are essential to give you slow release glucose. Try nuts, homemade salad dressing with olive oil and a vinegar on salads, marinated artichoke hearts, olives, avocado.
Hope this helps.
