10 Signs You Could Have Allergies

4. Abdominal Pain

If you often experience abdominal pain after eating, you may suffer from a food allergy or intolerance. It's important to better understand why you're having this reaction, as your immune system is creating an undesirable response.

If a certain food cannot be digested or causes irritation, this is more than likely an intolerance. This is often experienced when people cannot digest lactose or gluten. If you suffer from any abnormal stomach pain, it's critical that you speak to your doctor - especially if it's severe.

3. Fatigue

If you are always tired, there are a number of possible reasons why. You could be persistently dehydrated, sleep deprived, nutrient deficient, and more. The truth is, if you seem to be tried for three or four months straight, you could be suffering from allergy-induced chronic fatigue syndrome (CFS).

Although researchers are still trying to uncover what the exact cause is, it's been found that more than half of those with CFS, also have allergies. An over-reactive immune system may be causing symptoms of fatigue.
