Scientists at the Meir [mey-EER, MAHY-er] Medical Center in Israel have discovered that chewing a gum actually causes migraine.
The group of scientists, spearheaded by Dr. Nathan Watemberg, asked 30 teenage patients to quit chewing gum for a month. These patients were having chronic headaches and had the habit of chewing gum for an hour to six hours daily. The researchers then observed if the participants still experience severe migraine after the test.
After a month of not chewing gum, 19 of the 30 patients reported that their headaches disappeared entirely. Seven patients also said that the frequency and intensity of their headaches significantly decreased.
To verify the conclusion, 20 of the patients were asked to pick up gum chewing for two weeks. All of the patients stated that the symptoms of migraine returned after only a few days.
Some studies claim that headache due to gum chewing is caused by aspartame [uh-SPAHR-teym, a-SPAHR-, AS-per-teym], the artificial sweetener often used in gum. However, this explanation was disproved by scientists. They say that gum maintains its flavor for only a short time, suggesting that gum does not have much aspartame. Thus, the possibility that the artificial sweetener causes headaches is unlikely.
Other studies also explain that gum chewing causes stress to the temporomandibular joint (TMJ), the part of the body where the jaw meets the skull. When the TMJ is stressed, it malfunctions and leads to headaches.
Today, about 87% of teenagers who often chew gum suffer from regular headaches. With the recent study’s discovery, doctors may no longer need to conduct additional tests or prescribe extra medication to cure the illness.
