A False Sense Of Hypoglycemia

By Nora Saul, M.S., R.D., C.D.E., Manager of Nutritional Services at Joslin Hypoglycemia is defined as a blood glucose level below 70mg/dl. But many people find that they feel the symptoms of low blood glucose at levels much higher than expected. Some patients have come into my office reporting getting sweaty, hungry and tachycardic at levels in the mid 130s. Symptoms of hypoglycemia are individual, but may include extreme hunger, nervousness, excessive perspiration, rapid heartbeat (tachycardia), headache, fatigue, mood changes, blurred vision and difficulty concentration and completing mental tasks. Extremely low glucose levels can lead to disorientation and convulsions. People who take insulin or some oral medications that cause the pancreas to produce insulin are usually prone to episodes of hypoglycemia. This is especially true if they are attempting to keep their glucose level as close to normal as possible. But, people in poor control can also have hypoglycemic reactions as they swing from high to low glucose levels. False hypoglycemia is usually due to one of two causes. The first can be compared to an incorrectly programmed thermostat. If you usually keep your room at a st Continue reading >>

    What's going on if I feel hypoglycemic but blood sugar looks normal?

    I keep feeling suddenly dizzy, nauseous, light-headed, trembly, etc. like I've always thought meant my blood sugar was low. Eating carbs seems to usually stop it. But I got a glucometer and according to it my blood sugar is normal during that time. I've got to wait until Feb. 10 for my MD to fit me in, but went to the ER this weekend with hypertension - heart was beating irregularly and fast, super high blood pressure, dizzy, shaky, weak muscles, felt stupid and confused. It felt like I was going to die. I'm trying to figure out how to prevent this from happening again while I wait for blood work results to come back. My book "The Schwartzbein" Principle says to eat small meals and snacks with the carbs balanced with protein and fat, so I'm trying that.
    My current theory is that my body ramped up the adrenaline to make up for low blood sugar, and the adrenaline did that to me - ?
    I got some l-theanine to counteract adrenaline, and so far so good it seems to help but it's only been a day.
    I'd just started to diet (New Year's thing) by eating a lot more fruit and veggies, less carbs, so I'm wondering if the carbs getting low combined with insulin resistance might have made me start feeling this way? I know I also have some serotonin and thyroid problems, but it's hard to tell what's causing what.

    Hard to know without à meter. Fruit turns to sugar and you could have what's called a hyper\hypo episode. Blood sugar goes up then goes down but they need to get to the bottom of it.

    Do you think that "low blood sugar feeling" is actually from low blood sugar or from adrenaline kicking in to raise it?

  • What Blood Sugar Is Considered Hypoglycemic

    Eating simple carbs such as sweets will initially cause a blood sugar spike, then the insulin response will trigger and (unless you are a diabetic or insulin resistant) the insulin will cause the blood sugar level to fall rapidly.
