Mast Cell Activation Syndrome (MCAS) is when the mast cells overreact to any stimulus causing what is called Mast Cell Activation Disease (MCAD) which is an inappropriate mast cell activation. Mast Cell Activation Disease (MCAD), occurs when the mast cells become dysfunctional, becoming hyperactive in their protection and detect minor events as an invasion. Mast cells are a type of white blood cell, immune/defense cells, that exist throughout the whole body. They exist in all the tissues; the bone, muscles, tendons, ligaments, circulatory system; affecting all the organs in the body, the tissues, the nerves, the sinuses, the respiratory system, the digestive system, and even the functioning of the brain. Mast cells control our immune system and regulate our healing, Mast cells, when detecting a problem such as an injury, virus or bacteria, mold, foreign material can react explosively, producing and releasing into the tissues and organs a wide range of potent chemical signals to help the body heal and recover.

Sometimes after the body goes through a traumatic event or a series of traumatic events the body can get stuck in a flight or fight mode becoming hyper-vigilant, creating hypersensitivity in the human body. When this occurs over a longer period of time it can progress into Mast Cell Activation Disease.

Now, I am sure many of you are wondering how candida or fungal infections can cause Mast Cell Activation Syndrome.

In the article, Opportunistic pathogen Candida albicans elicits a temporal response in primary human mast cells, written by Jose Pedro Lopes, Marios Styliano, Gunnar Nilsson, & Constantin F. Urba, C. albican was shown to be a potent stimulator of mast cell activation. According to their publication, C. albican when attached mast cell from the outside "resulted in loss of membrane dye and thus integrity of the host cell membrane, clearly demonstrating that mast cells are ruptured by C. albicans. This, at least in part, explains the high mast cell death during interaction with C. albicans, because it is a more frequent event (in 15-20% of the cells). C. albicans can induce cell death in host cells."

What I wish to emphasize is that at the root of many illnesses is an activation of the mast cells that can elevate to the point where the mast cells become over-active and hypervigilant, causing a whole host of symptoms.

Another point I wish to express is that Mast Cell Activation Disease is not picked up in routine lab testing and it often does not cause abnormalities. MCAD was not even recognized as an illness until 2007. Many allergy doctors are not even familiar with it. For instance, my general physician told me over the years that I just had "allergies". I was forming heavy phlegm in my lungs and bronchials, causing violent coughing that resulted in an umbilical hernia. When I went into the allergist they did elaborate IgE testing for everything with a skin test and to further verify results as a blood test. After all, this was completed, I was told that I was not allergic to anything. I was dumbfounded because if I got around dust or mold my nose would run and I would cough violently. I also would cough violently after I ate. Now I know that Mast Cell Activation Syndrome was the root cause of my illness and that my mast cells were creating high histamine levels, which was aggravated by eating high histamine foods.

MCAD is a chronic, multisystem illness that causes "histamine intolerance" causing excess histamine production and inflammation which can potentially affect every organ in the body. The result of this high histamine production is diamine oxidase (DAO) enzyme deficiency.

This is why we recommend supplementing with Histamine Digest PureMAX with DAO to reduce histamine and raise DAO levels.

With Mast Cell Activation Disease, healing is a slow, but steady process that can take months and even years. It is an illness that requires constant vigilance to recognize and treat the factors that caused a raised mast cell activity and careful dietary monitoring of low-histamine foods. Each individual is unique as to what is effective and ineffective and will need to stay aware of their own reaction to the environment, electronics, and food.

The following situations can be factors in developing Mast Cell Activation Syndrome or Multiple Chemical Sensitivity.

  • Intestinal infection or disease
  • Infections in the mouth, cavitations (infections in the jaw), mercury fillings, and mercury toxicity.
  • Exposure to RF (radio frequencies), wireless technology, cell phones, cell towers. Exposure to any device with SMPS (Switch Mode Power Supply). This can be from an electric smart meter, a new variable speed furnace, and yes... LED lighting (alternates between an AC and DC current.
  • Chemical Exposure. Herbicide and/or pesticide poisoning. Glycophate (Roundup) poisoning.
  • Heavy Metal Poisoning - toxic levels of mercury, lead, aluminum, chromium, cadmium, arsenic, etc.
  • Parasites
  • Malnutrition - poor absorption of nutrients
  • Mold exposure
  • Plastic toxicity
  • Fungal and/or candida infections
  • Having a severe bacterial or viral infection
  • Emotional trauma - divorce, death of loved one, financial problems, moving, war, a victim of violence, abuse.
  • Poor functioning gallbladder, liver, pancreas, and/or kidney. Unable to eliminate toxins effectively.
