Dear TeenHealthFX,

Sometimes I get Bad headaches after eating. Could this be related to blood sugar<

Dear Bad Headaches After Eating,

It would be helpful if you had a reading on your blood sugar. 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. A normal blood glucose level most likely would not trigger a headache.


There are numerous reasons why you could develop 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.


If you don't have a doctor and live in northern New Jersey, you can call the Adolescent/Young Adult Center for Health in Morristown 973-971-6475 or the Adolescent/Young Adult Center for Health in Summit at 908-522-5757 for an appointment. Outside this area you can check with your insurance carrier or a local Teen Health Center.
