Lip numbness and dry mouth is likely the result of a food allergy. Like any allergy, your body's immune system recognizes a certain food -- or substance in the food -- as an allergen. This triggers the release of antibodies to protect you from harm. In turn, the antibodies cause the release of chemicals that lead to symptoms associated with the condition. Take a moment to consider what you've eaten and note any other symptoms that manifest. If your condition worsens, seek medical attention.
Types
Most food allergies are linked to certain types of proteins. Shellfish is probably one of the more notable, but eggs, milk, fish and nuts, such as peanuts, walnuts and pecans, can all trigger an allergic response. Gluten, which is a protein found in many grains, including wheat, barley and rye, is an allergen for some people. Gluten intolerance is most often seen in people with celiac disease, a condition where the body can't tolerate this food component.
Concurrent Symptoms
Besides lip numbness and dry mouth, you may also notice some swelling to the lips as well as the face, tongue and throat. This can be accompanied by hives, itching, wheezing, nasal congestion and even breathing difficulties. Some people also suffer gastrointestinal issues, such as nausea, vomiting, diarrhea and abdominal pain or cramping, while other begin to feel dizzy, lightheaded or faint.
Treatment
Antihistamines can often reduce the symptoms you're experiencing. With the lip numbness and dry mouth, it's most likely a minor allergic reaction, so you should respond favorably to an over-the-counter medication. Follow the instruction on the packaging for proper dosage. If your symptoms worsen, antihistamines don't help. In this situation, you'll need epinephrine. This is given in the form of an injection to relax the muscles of the airways.
Recommendation
If you have a food allergy, always read the food labels to ensure that the product doesn't contain any ingredients that will cause an allergic reaction. Always weigh on the side of caution when uncertain of the ingredients. Even a tiny amount of food you're allergic to can cause a reaction. Always ask the ingredients of the foods at restaurants and social events, recommends the MayoClinic.com.
