Flaxseed is used as a dietary supplement to treat constipation and stomach irritation. Some people find that flaxseed helps reduce inflammation and pain associated with arthritis, and it may also decrease the amount of cholesterol in your body. Flaxseed is not recommended by Drugs.com for people who are allergic to flax, have a history of intestinal blockage, are pregnant or have a closure or swelling of the esophagus. An allergic reaction to flaxseed is possible, requiring assessment by your doctor.
Cause
All food-related allergies are caused by the same chemical reaction that takes place in your body. Your immune system is intended to protect your body from infectious organisms and disease by identifying harmful substances and attacking them. During an allergic reaction, your immune system accidentally identifies the proteins in the flaxseed as harmful. This causes your immune system to react as if the body were under attack. Immunoglobulin E antibodies and histamine are released to protect your body, but in turn cause allergy symptoms to develop.
Allergy Signs and Symptoms
Side effects after ingesting flaxseed may be similar to signs of an allergic reaction, and they need to be evaluated by a physician. Common side effects include gas, nausea and mild diarrhea. Signs and symptoms associated with a flaxseed allergy are nausea, vomiting, diarrhea, stomach cramping, abdominal pain, skin rash, hives, a metallic taste in the mouth, shortness of breath, wheezing, sinus congestion, sinus headaches and postnasal drip. Most allergy signs and symptoms develop within a few minutes after ingesting flaxseeds.
Severe Allergic Reaction
A severe allergic reaction to flaxseeds can lead to deadly symptoms that will require emergency medical attention. Severe allergic reactions will cause a condition called anaphylaxis. Anaphylaxis is an extreme allergic reaction that sends your body into a state of shock. Common warning signs and symptoms include rash; trouble breathing; chest tightness; hives; swelling in the mouth, lips, tongue or face; and discoloration of the skin, such as a grayish, dark purple or pale white color.
Treatment
No cure exists for an allergy to flaxseed, aside from avoiding the consumption of flaxseed. Participate in allergy testing to determine if you have an allergy to any other seeds, such as cocoa, sesame or poppy seeds. If you accidentally ingest flaxseed, minor allergic reactions may be alleviated by taking an oral antihistamine. If you develop a severe allergic reaction, call 911 immediately. An injection of epinephrine may be required to alleviate your symptoms.
