Low Blood Sugar: Causes, Warning Signs And Treatments

Low blood sugar, or hypoglycemia, is the most common and most dangerous condition for many people with type 1 diabetes (T1D). Very low blood sugar may lead to insulin shock, which can be life threatening if not treated promptly. Low blood sugar occurs when the body has too little food/glucose or too much insulin. The following are all potential reasons that a person with diabetes might have low blood sugar: Too much insulin taken Eating less than usual Eating later than usual Insulin was injected at a site on the body where the absorption rate is faster than usual Injecting extra insulin after forgetting about a previous dose More exercise than normal Illness or injury Other hormones Medication interaction The following is a list of general symptoms that indicate low blood sugar (the person with T1D may exhibit one or more of these and symptoms may change from event to event) Dizziness Nervousness Personality change/irrational behavior Blurry vision Shakiness Nausea Crying Sluggishness Sweating Poor coordination Hunger Lightheadedness Irritability Drowsiness Erratic response to questions Inability to concentrate Severe symptoms (symptoms as listed above, plus): Convulsions or seizu Continue reading >>

    There are likely several reasons for this occurring (multiple effects caused by several hormones, mental states, physical states, etc..). However, my speculation is that it has to do with your blood glucose levels. When a person gets hungry, [s]he will likely have a lower level of blood sugar, and the body will want to replenish the blood sugar levels through eating. In order to make the person 'hungry', the body circulates ghrelin throughout the blood to increase your appetite and make you eat. However, after some time of not responding to the desire to eat, the body will naturally burn off its reserves (glycogen, fats, then muscle) to increase blood sugar levels. At this point, while you won't think you're full (since you haven't eaten, and you're not secreting significant quantities of leptin), due to diminished quantities of ghrelin, since your blood sugar is not longer extremely low, you won't feel so hungry anymore.
    *Please keep in mind however, that starving yourself is not the way to lose weight. When the body burns up its reserves, it will try to replenish those reserves as quickly as possible. Thus, the best route is through a very slow and steady decrease in the consumption of food until a healthy calorie load is reached, and allowance of the body to equilibrate over those conditions. I didn't want to have to post this post script, however, to prevent anyone from doing something dangerous like starving themselves to lose weight, I'll post it anyway.

    Hunger pains are the muscle contractions in your stomach when you haven't eaten or drank for a certain period of time, or triggered by low glucose levels. Because these are muscle contractions they will stop on there own. It's kind of like an alarm clock telling you it's time to eat/drink something, by not doing anything it's like hitting snooze on your clock. You'll find they probably start again within 15/20 mins.

    A little side note, if they don't stop seek medical advice because this could be a sign of gastrointestinal problems.

    Appetite/hunger function on a Cyclical basis. Imagine a heartbeat on a monitor, it goes up then back down. Appetite does the same on a roughly 2 hour basis. you can disrupt that by eating, having a reliable routine time when you eat etc which will impact those cycles

But in fact, for several years now diabetes experts have known that for most people that's not only unnecessary, but potentially harmful. Here's what you should a ...
