Side Effects of Flaxseed in Children

Flax seeds and the oil that can be extracted from them are a rich source of omega-3 fatty acids. These acids, which are also found in fish oils, are an essential part of a healthy diet for children as well as adults, as they help keep the heart healthy and cholesterol levels low. The human body is unable to manufacture these acids on its own, so they must be consumed in foods such as flax seed. However, despite their beneficial aspects, there are potential side effects.

Inflammation

• Flax seed is known to help ease inflammation--it is often recommended for elderly sufferers of arthritis--but it can also exacerbate areas of inflammation on children's bodies, such as when they have stubbed a toe or bumped their heads.

Medication Effectiveness

• Flax seed can inhibit the body's ability to break down and absorb medications or other nutritional supplements, particularly those that are taken orally. It is advisable not to give children flax seed if they are taking other supplements or medicines, although your doctor can advise you on specific types.

Diarrhea

• Flax seed does have some laxative effects, particularly if taken in large doses. It can also have the side effect of producing excessive gas or loose stools.

Diabetes

• If your child suffers from diabetes, they are unlikely to be able to process omega-3 fatty acids in the form in which they are found in flax seed. Such children should get their requisite omega-3 fatty acids from dietary sources of oily fish.

Allergy

• Your child may have an allergic reaction to flax seed. Unfortunately, there is no test to determine this prior to the reaction manifesting itself. Watch for the appearance of hives or a rash, excessive itching, trouble swallowing or wheezing. Discontinue giving the child flax seed if these symptoms appear and consult a doctor.

Bleeding

• In rare cases, flax seed can cause excessive bleeding or make children's skin more susceptible to bruising. In exceptional cases, it can lead to a hemorrhage in the brain. Symptoms to watch for include frequent severe headaches, fluctuations in vision and numbness in the limbs. If your child displays any of these, take him or her to hospital immediately.
