Headache After Eating

Dear TeenHealthFX,

Had major headache. One hour after meal blood sugar was 78 is this normal?


Dear Headache After Eating,

78 is within a normal blood sugar range.  The normal range for blood sugar after eating is 70 – 140mg/dl.

There is a wide range for normal because the blood glucose level depends on the content of the meal, the time since the meal, level of activity and several other variables.  It is unlikely that a normal blood glucose level would trigger a headache.

There are literally hundreds of reasons for developing a headache.  It may or may not have been related to the meal.  You didn’t say if you treated the headache, what you did to treat it, and whether or not the treatment was successful.  These are important clues to the headache cause as well.

If you feel the headache was related to the meal, you may want to keep track of possible causes.  Write down what you ate before the headache.  Monitor yourself and if you have a similar episode, write down the meal contents again.  Compare them to the previous episode to see if there are any foods that are the same.

Your headache may or may not be related to your blood sugar level but if it seems that this pattern continues, it is definitely worth a trip to the doctor to find out. Since you are monitoring your blood sugar level TeenHealthFX is guessing you are already under a doctor’s care. It would be a good idea to discuss the issue with him/her. Headaches from all causes are not uncommon but with some care they can be avoided or minimized.
