Bee pollen is the term given to pollen and nectar from flowers collected by bees. Bee pollen can contain a wide range of vitamins, minerals and nutrients, depending on which flowers the pollen is collected from. People take bee pollen to treat several different medical conditions, although little evidence has been found supporting its use. While generally safe and well tolerated, in rare cases bee pollen can cause severe side effects.
Allergic Reaction
Bee pollen can cause an allergic reaction in certain individuals. In rare cases, the allergic reaction may be severe and life-threatening. People who are allergic to bee stings and bee venom should avoid bee pollen supplements. In addition, people who are allergic to honey, ragweed, chrysanthemum, apples, celery or carrots may also be sensitive to bee pollen.
Sneezing and Headache
The immediate symptoms of an allergic reaction to bee pollen are sneezing, coughing and headache. Severe itching may also develop, as well as paleness. Swelling may also occur, which can be particularly noticeable in the face, lips, throat and hands.
Gastrointestinal Effects
Allergic reactions to bee pollen can also cause a condition called eosinophilic gastroenteritis, in which cells of the immune system invade and attack the digestive tract, reports the Sloan-Kettering Memorial Cancer Center. Symptoms of eosinophilic gastroenteritis include nausea, vomiting, diarrhea, and abdominal pain and discomfort.
Anaphylaxis
In rare cases, a severe allergic reaction known as anaphylaxis can result from an allergy to bee pollen. Anaphylaxis can be life-threatening, resulting in difficulty breathing, low blood pressure and pulse rate, and the possibility of coma. Symptoms of anaphylaxis include severe swelling of the face and throat, wheezing, coughing, dizziness and fainting. Severe nausea and vomiting may also occur. If you suspect that you or someone you know is experiencing anaphylaxis, contact emergency medical services immediately.
