Without a blood test, it is very difficult to determine your blood sugar levels. Saying that you have low blood sugar is pretty much based on symptoms if there is no actual testing involved.
Low blood sugar can be caused by a variety of things. One of the most common is a situation where a person will eat a large amount of simple carbs--as they are digested, they release a big gush of glucose into the blood stream. The super rapid rise in blood sugar will cause the body to send out insulin in hyperdrive mode, usually sending more than is needed. The extra insulin will cause blood sugar levels to drop below normal, causing the ravenous hunger, craving for sweets or simple carbs, shakiness, weakness and nausea.
People usually give into the craving and eat another simple carb--overeating them typically, due to the intense hunger. This causes another insulin spike, and the cycle starts all over again.
People who have problems with hypoglycemia that isn't induced by eating too much in the way of simple sugars may have a problem with maintaining blood glucose at normal levels for other reasons. Usually these people have to eat at very regular intervals and make sure they include some quicker absorbing (higher glycemic) carbs and some slower absorbing (lower glycemic) carbs at every meal and snack.
Hope this explains it a little.
