Itchy skin is a classic allergy or food sensitivity problem however it can also be a gut problem from yeast. The “common” food allergy testing is where they look for a reddening of your skin with the antigen, tests for IgE antibodies, which most of us don’t have. This is an immediate reaction similar to someone with a shellfish allergy who needs to be rushed to the hospital if they ate that food. If your immune system is under stress, you will most likely react to the common allergens – mold, dust mites, ragweed, etc. Naturally, your body can’t handle them if your immune system isn’t up to par. Most people have an IgG (delayed reaction) allergic response, where they can react to a food eaten up to 72 hours later! That makes it hard to determine the actual allergy. Although there are allergy tests for these, which can be extremely helpful at times, they are expensive and not 100% accurate. The itching is caused by the histamine irritation to your skin, and possibly eyes, ears and nose. The dead giveaway that this is the case is that an antihistamine works great for you. Rather than taking a medication all of the time, and especially since they don’t work 100% for most people, it’s better to find out why it’s happening in the first place through a proper neurological evaluation.
Dysbiosis (a balance of unhealthy gut flora) can also cause itching. Yeast overgrowth, occurring in the digestive system of both men and women from lack of healthy bacteria (probiotics) and too much sugar is often the reason.
A lack of calcium can also cause itchy skin as can a deficiency of vitamin A – which is only found in animal products (e.g. meats, fish, dairy) – not beta carotene found in many fruits and veggies.
