Caffeine is mostly known for its ability to help you wake up in the morning, but in certain situations, caffeine may affect nasal mucus. Your sinuses are made of soft tissues that are lined with mucus membranes that help keep your nasal passages supple and protects the body from foreign particles. Any irritation or change in environment may trigger increased mucus production and nasal congestion. If you notice a change in your nasal mucus from caffeine, call your doctor.
About Caffeine
Although caffeine is naturally found in various foods, the substance is still a drug that needs to be used in moderation. Most people consume caffeine through drinking coffee, sports beverages, soda and tea. Caffeine is sold as an over-the-counter medication to help you stay awake longer or improve mental clarity but is intended for short-term use, according to Drugs.com. Caffeine can cause a wide range of side effects but rarely causes a change in nasal mucus, unless there is an underlying condition. Common reasons your nasal mucus may change are from an allergic reaction or caffeine withdrawal.
Allergic Reactions
It’s possible that you may have an allergy to caffeine or one of the added ingredients to caffeinated products. For example, if you drink coffee with milk, the change in nasal mucus may be from a minor milk allergy. Some over-the-counter medications combined caffeine with aspirin, which is another highly allergenic substance. Before ingesting any caffeinated product, read the product label and ingredients to determine any potential allergens. An allergic reaction releases immunoglobulin E antibodies, histamine and other chemicals in the body that cause inflammation and mucus production, according to the American Academy of Allergy, Asthma and Immunology.
Caffeine Withdrawal
If you suddenly stop consuming caffeine and your body is accustomed to a certain amount daily, you can develop changes in nasal mucus as a side effect, according to MayoClinic.com. According to CBS News, an estimated 13 percent of people develop caffeine withdrawal symptoms and decide to continue using the substance. MayoClinic.com states that you should talk with your doctor if you develop any of the following symptoms from abstaining from caffeine: stuffy nose, headache, anxiety, irritability, nausea, nervousness and muscle tension
Warning
In rare cases, major changes in nasal mucus along with facial swelling, shortness of breath, chest tightness, a drop in blood pressure, hives and an increased heart rate may be a sign of a severe allergic reaction. This type of allergy can cause life-threatening symptoms and will require emergency medical attention.
