Hypoglycaemia (low Blood Glucose) In Non-diabetic People

What is hypoglycaemia (low blood glucose)? Hypoglycaemia or low blood glucose is a condition in which the level of glucose (sugar) in the blood, drops below a certain point (about 2.5mmol/l). The condition manifests itself by a number of symptoms that usually disappear 10 to 15 minutes after eating sugar. People differ slightly in the exact level of blood glucose at which they begin to feel symptoms of low blood sugar. Insulin is normally produced in the pancreas and helps the cells in the body absorb glucose from the blood. Normally, the glucose level rises after a meal. Too much insulin in the blood and other diseases can cause hypoglycaemic episodes (also known as 'hypos'). What can cause hypoglycaemic episodes in non-diabetic patients? Too much insulin in the blood: reactive hypoglycaemia (see below) a tumour – very often benign – in the insulin-producing pancreas. This is a very rare condition indeed Other diseases: a disease in the adrenal glands (Addison's disease) a weakened pituitary gland a severe reduction in liver function patients who have had their stomach removed fasting, malnutrition Reactive hypoglycaemia is possibly the most common reason for hypoglycaemia in Continue reading >>

    How Low Can Your Blood Glucose Level Go Safely?

    Low blood sugar can result in weakness, confusion, headache, irritability, excessive hunger, excessive sweating or fatigue.
    The normal range of blood sugar is 80 - 120 mg/dL (milligrams per deciliter) in the morning (after fasting for at least 8 hours). Normally, if the level drops below 70 mg/dL, the person is said to suffer from hypoglycemia or low blood sugar levels.
    You may experience trembling and if your blood sugar still drops down, you could have a seizure. Increasing glucose intake, like drinking fruit juice, can help raise your blood glucose.
    The ideal blood glucose levels range for you may be different from another person's and the level of glucose in blood would keep on changing throughout the day.
    Similarly, the point at which the severe effects of insufficient blood sugar would be experienced may vary from person to person.
    For some, sugar level below 70 mg/dL can be hypoglycemic, while for others the 'trigger point' can be at 60 mg/dL.
    So, you need to consult your doctor about how much of blood sugar should be running, to keep you safe. He will tell you what blood sugar range is normal for you.


    Lows are extremely dangerous, people who continue to go low often quit getting the warning signs. That is right your system will quit warning you until you like a light switch go into seizures and coma. One of my best friends has experienced this two times because he quit getting warnings. Had his wife not found him this last time when she did he would be dead. They sent him to a large hospital by lifeflight because the local hospital didn't have the specialists needed to save his life. It takes a few months of regular blood glucose numbers to reset your warning system if you have caused it to lower or go away totaly. Yes some people feel it at different times because they have lowered their body thermostat warning system lower by continually going to low. This information come from a book written by a diabetes specialists name Dr Bernstein ( Diabetes Solution ).
    Just be very careful, don't play roulette with low blood glucose it can be as deadly as a gun.

    My lowest low was 29, a couple months ago, while I was asleep. I only woke up because I had to go to the bathroom, and I figured I should check my blood sugar because I was pretty dizzy. Last night, I had a low of 39. I almost never feel lows until I'm in the 50's or 40's. My doc is concerned about nighttime hypoglycemia because my A1Cs are always lower than what they should be, considering my highs. I've only been diagnosed with type 1 for 2 1/2 years, but I stopped feeling symptoms of highs and lows around 6 months in, so at this point I'm fundraising for a diabetic alert dog.
