Must Read Articles Related To High Blood Sugar (hyperglycemia)

A A A High Blood Sugar (Hyperglycemia) Whenever the glucose (sugar) level in one's blood rises high temporarily, this condition is known as hyperglycemia. The opposite condition, low blood sugar, is called hypoglycemia. Glucose comes from most foods, and the body uses other chemicals to create glucose in the liver and muscles. The blood carries glucose (blood sugar) to all the cells in the body. To carry glucose into the cells as an energy supply, cells need help from insulin. Insulin is a hormone made by the pancreas, an organ near the stomach. The pancreas releases insulin into the blood, based upon the blood sugar level. Insulin helps move glucose from digested food into cells. Sometimes, the body stops making insulin (as in type 1 diabetes), or the insulin does not work properly (as in type 2 diabetes). In diabetic patients, glucose does not enter the cells sufficiently, thus staying in the blood and creating high blood sugar levels. Blood sugar levels can be measured in seconds by using a blood glucose meter, also known as a glucometer. A tiny drop of blood from the finger or forearm is placed on a test strip and inserted into the glucometer. The blood sugar (or glucose) level Continue reading >>

    I have a slew of symptoms that (I think) point to prediabetes including crashing after meals, headaches after meals or after skipping meals, anxiety, irritability, a droopy left eye lid, lots of fatigue, falling asleep after breakfast/midday meal, high LDL (read this is a symptom?) feeling WAY happier/less agitated after a meal (I get super "hangry" until I eat, ridiculously bad), etc.
    So I bought a blood glucose kit last night and after a 12 hour fast I woke up this morning with a reading of 101.
    I exercise regularly, lift heavy weights, train Jiu Jitsu, eat fairly healthy, and am about 174 pounds, ~15% bodyfat and 5"10.
    Kind of a ramble/brain dump here as I have to drive three hours right now, but I'm a bit on edge about all of this so wanted to reach out and see if someone could give me some advice on what to do next?
    I assume check my levels the new few days when I wake up. Any other times I should check them?
    Also, would switching to a diet such as Paleo (high fat with only complex carbs?) be a good idea?
    I have no insurance as I am self employed, but should I see a doctor? Or will they just tell me to come back when my levels are higher?
    Any info or advice is much appreciated, and sorry for the brain dump!

    If you eat a lot of carbs, I wonder if you're crashing from a sugar high and that is making you "hangry". If you do then you should probably consider reducing or changing your carb intake. I can't comment on whether Paleo (or other diets) would help but I think that changing your diet is worth doing for a couple months just to see how it makes you feel.
    As for your blood sugar of 101 when you wake up, I WISH mine were that good. Yours sounds completely normal and not worth worrying about. As for when you should test, I would say 1-4 hours after a meal. If you are REALLY curious how your body is handling things, you could do it every hour after a meal for the next 4 hours. Just remember not to get worried about whatever the results are. It is normal for your blood sugar to spike after a meal. I would only get concerned if you see blood sugars above 200 that are sustained for a long period of time (many hours).

    I'm sorry, you are seeing it through the eyes of a diagnosed type 1 but that is very poor advice to a non-diabetic concerned about their possible diagnosis.
    Read this to see why:
    Source (pdf): Standards of Medical Care in Diabetes—2015 Abridged for Primary Care Providers, Table 2
    Criteria for the Diagnosis of Prediabetes and Diabetes
    Test Prediabetes Diabetes

    5.7– 6.4%
    100–125 mg/dL (5.6–6.9 mmol/L)
    ≥126 mg/dL (7.0 mmol/L)
    140–199 mg/dL (7.8–11.0 mmol/L)
    ≥200 mg/dL (11.1 mmol/L)*
    ≥200 mg/dL (11.1 mmol/L)†
    *In the absence of unequivocal hyperglycemia, results should be confirmed by repeat testing.
    †Only diagnostic in a patient with classic symptoms of hyperglycemia or hyperglycemic crisis. RPG, random plasma glucose*.
    Non-diabetics do not exceed 99mg/dl fasting or 140 post-meal unless they are taking corticosteroids or similar medications.
