What Causes Extreme Tiredness After Eating Sugar High Cookies?

Almost immediately after eating a very high sugar cookie,I am extremely tired....to the point where I must lie down. Over the last few months I am so tired that I can fall asleep sitting up reading the paper. Yet I can't fall asleep easily at night in bed. Could this be diabetes?

Hi,

As you have mentioned feeling of tiredness after eating high sugar cookie.
There are two possibilities for that-
1) Reactive hypoglycemia:
Low blood sugar level due to high sugar load (carbohydrate).
This is due to rapid release of insulin in response to high carbohydrate load which leads to low blood sugar level (hypoglycemia).
Hypoglycemia usually associated with tiredness, sweating, palpitations, restlessness, unusual hunger, dizziness.
2) Hyperglycemia (Diabetes- High blood sugar level)

I want know
1) Any associated symptoms.
2) Your height weight.
3) Family history of diabetes.

I will advise you to check blood sugar level during episode which will give clue to diagnosis.
Depending on result further action plan can be done.

If blood sugar level found low

If blood sugar >70 then you can confirm diabetes by doing Oral glucose tolerance test (OGTT) or HbA1c.
