Daily Headaches related to Fasting

by Lisa
(Jax, FL)

Hi.. I have a terrible headache upon awakening every morning. After I eat breakfast, the headache doesn't go away; it intensifies. I have seen an endocrinologist as I thought this was hypoglycemia. After an in-office fasting test, he says I exhibit symptoms and need to monitor my sugar levels, but the headaches he says aren't related to the sugar. He says I do have hypoglycemia so I have to eat every 3 hours during the day. The fasting test was relatively normal. I started at 76 at 9 that morning, slowly crept down to 73 in three hours and 64 after 8 hours. Although I felt weak and disoriented, I didn't have the shakes, etc.

But everyday after I awaken, I feel extremely hungry and only sometimes get the shakes,etc. Every day though I have awful headaches that make my day unbearable.

I am a 46 year old teacher with 3 children. I do not smoke or drink but am a diet soda-aholic. I take fioricet, goodys (a whole box in 3 days), and cephadyn. The endo says these headaches should go away once I eat if they are hypoglycemia related but they worsen.



Hi Lisa,

I will have to respectfully disagree with the endocrinologist. In the world of headache, hypoglycemia is a known cause of headache, particularly migraine.

I have also had several patients who developed chronic daily headaches secondary to aspartame which is what is in diet soda. Depending on how much you consume, there is also the caffeine issue which would definitely cause an AM headache as the caffeine wears off. Therefore, you might want to cut way back on the diet soda and keep it to one 6-8oz serving per day at most.

Finally, the fiorcet, and the Goody's powder (for other reader's this is aspirin compound) are also fueling your headaches and causing analgesic rebound headaches which eventually move into daily headache.

I would advise that you consider seeing a neurologist and also ask about getting an MRI of the brain.

Good luck!
