Home > Respiratory System > Respiratory System of the Head and Neck > Larynx. The larynx is a tough, flexible segment of the respiratory tract connecting the pharynx to the trachea in the neck. It plays a vital role in the respiratory tract by allowing air to pass through it while keeping food and drink from blocking the airway.
Common side effects from nicotine gum include bleeding gums, too much saliva, hiccups, indigestion, slight swelling of the mouth, injury to teeth or cheeks, nausea, upset stomach and sore throat. Less common or rare side effects may include diarrhea, dry mouth, swollen gums, sores in the tongue/throat/mouth, muscle pain, rashes and sweating.
Nicotine can cause many health problems. It can temporarily raise blood pressure and heart rate because it causes blood vessels to narrow. Nicotine can also make the blood more likely to clot and block an artery, and it can cause damage to the lungs and make breathing difficult. Nicotine in the body is first processed by the liver and then excreted by the kidneys. Over time nicotine can have negative effects on the kidneys.
