Nicorette chewing gum, used to help people stop smoking, works by lessening withdrawal cravings. The gum releases nicotine in the mouth, which absorbs through the lining of the cheeks. The University of Missouri Student Health Center website recommends using it on a schedule and chewing it a few times until the nicotine is apparent before holding it between the lip and gum.
Hyperinsulinemia
Nicorette gum may cause hyperinsulinemia in some long-term users, reports Drugs.com. According to MayoClinic.com, hyperinsulinemia, a condition characterized by high levels of insulin in the bloodstream, presents with no obvious signs or symptoms with the exception of possibly causing low blood sugar, also called hypoglycemia. The underlying cause dictates the treatment for hyperinsulinemia. These high levels of insulin usually result from insulin resistance in gum users with type 2 diabetes.
Stomatitis
According to Drugs.com, stomatitis may occur as a complication of chewing Nicorette gum. Stomatitis presents with swelling, redness and painful ulcers in the mouth. This condition results from a variety of causes; however, stomatitis related to Nicorette gum likely happens due to a chemical irritant. The Merck Manuals Online Medical Library reports that tobacco is one of the most common causes. Treatment of this complication includes cessation of chewing Nicorette gum, as well as the use of anesthetics, protective coatings, corticosteroids and antibiotics to ease symptoms.
Glossitis
Glossitis, a condition characterized by a swollen tongue and changes in its color, may occur as a complication of chewing Nicorette gum, according to Drugs.com. Glossitis results from exposure to irritants like tobacco, as well as infections, injury and allergic reactions. MedlinePlus reports that the symptoms of this condition include the smooth appearance of the tongue, tongue color developing to a dark red, a sore or tender tongue, and difficult chewing, swallowing or speaking. Physicians recommend to stop using Nicorette gum and seek medical help to treat the swollen tongue.
