Non-fasting blood sugar was 162. Had been on prednisone. Could high blood sugar make someone feel tired a lot? Am not diabetic (yet?)

Not the right test: You need to have blood glucose tested after an 8 hour fast. Alternatively you could get an A1c test and either would be more useful in deciding the diagnosis of diabetes. Your tiredness is more likely due to the issue for which you are taking prednisone. ...Read more

Prednisone (Definition)

Prednisone is a synthetic cortisone. The body makes cortisone, a natural hormone made in adrenal glands. The body converts it to Hydrocortisone to become active. 25 mg of cortisone has about same effect as 5 mgm prednisone. The average person would produce 3-6 mg of pred daily. So why use a substitute? The synthetic has more anti-inflammatory effect; but has less effect ...Read more

I take prednisone 40mg daily for asthma flair up. I took my blood sugar 20-30 min after eating cookies and popcorn it was 208. Should I worry?

I take prednisone 40mg daily for asthma flair up. I took my blood sugar 20-30 min after eating cookies and popcorn it was 208. Should I worry?

High Blood Sugar: Worry is not a productive emotion. But 208 is a very high blood sugar. Prednisone definitely will cause elevations of blood sugar, but you need to be evaluated. Having your height and weight would be useful also to estimate your diabetes risk. I would eliminate all sweets and recheck blood sugar. Don't forget to use exercise to lower blood sugar when your breathing is better. ...Read more

Why does prednisone and steroid shots for allergies make me so sleepy? My blood sugar and vitals are all normal. I just wondered why the odd reaction.

Why does prednisone and steroid shots for allergies make me so sleepy? My blood sugar and vitals are all normal. I just wondered why the odd reaction.

Unusual: HIgh dose of steroid often stimulates instead of sedating people. In fact, I usually warn the patient about potential insomnia on the day when steroid is given or started. Occasionally, this may cause low serum potassium level which may lead to weakness and possibly even cardiac effect. However everyone is different and I am no longer surprised from paradoxical responses in some people. ...Read more

Would having hyperthyroid problems cause high blood sugar levels?

Maybe impaired: The effects of thyroid hormone on blood glucose is complex. Insulin levels may be increased, but there is also resistance to Insulin action. Often, fasting glucose is not affected, but glucose may increase more after a meal (i.e. Impaired glucose tolerance).
