Living with Mast Cell Activation Syndrome (MCAS) usually results in widespread mast cell activation syndrome symptoms that are seemingly unrelated. Unfortunately, most people go many years or even their whole life without a diagnosis.
If you’ve been diagnosed with MCAS or suspect you have this condition, the best course of action is making a series of lifestyle changes and working with your functional medicine doctor. Fortunately, many of the changes are easy to implement and you’ll see the benefits from implementing them fairly quickly.
Try not to get overwhelmed by this list, instead pick one or two items and incorporate them into your routine. Add a few items week by week, and soon enough you’ll have a comprehensive plan that has the potential to significantly improve your symptoms and your quality of life.
1. Adopt a low histamine diet
Avoid leftover foods, alcohol, cured meats, canned fish, pickled and fermented foods, berries, citrus, nuts, chocolate, dairy, yeast, soy sauce, tomatoes, vinegar, and preservatives. A comprehensive guide to a low histamine diet can be found.
2. Avoid triggers of MCAS (non-food items)
Avoid temperature extremes, mold, emotional stress, insect bites, chemicals in personal products, medications that liberate histamine of block DAO, sodium benzoate (common food preservative), airborne chemicals, smoke, heavy metals and anesthetics.
3. Work on your gut health
Good gut health is a cornerstone of overall wellness and will help you get your MCAS under control. Cut back on food that damages the gut or causes inflammation. Take probiotics and a DAO enzyme (generic name Umbrellux DAO).
4. Stabilize mast cell mediator release
Stabilize mast cell release of histamine with quercetin and vitamin C.
5. Use H1 and H2 blockers every 12 hours
Try using 5 mg of levocetirizine twice daily and 20 mg of famotidine twice daily.
6. Block and reduce nighttime histamine release
You can block nighttime histamine release and get a better night’s sleep by taking 0.25 -1 mg of ketotifen or zaditen at night.
7. Treat existing infections
Treat any existing infections to help your body heal and reduce mast cell triggers. Get a thorough examination with your functional medicine doctor and test for any pathogens.
8. Identify and remove toxins and allergens
When you have MCAS, you’ll do your body a world of good by reducing its toxin burden. You can reduce your exposure to toxins in your daily life through cleaning up your personal care products and opting for natural solutions, using natural household cleaners, and removing mercury fillings.
9. Take helpful nutrients
Support your health with important nutrients that assist in treatment. Some of these include vitamin B6, alpha lipoic acid, vitamin C, selenium, omega-3s, N-acetylcysteine, methyl-folate, SAMe, and riboflavin.
10. Add supportive herbs
Take nigella sativa, butterbur, turmeric, ginger, and peppermint to support your MCAS treatment.
11. Get into a routine and stick to it
Try to stick to a routine because your body’s cycles are closely linked to your daily activities. This will also help you get high quality sleep, which is essential to reducing the impact of MCAS on your life.
12. Reduce stress
Stress can activate your mast cells and cause them to release mediators like histamine. Reducing stress is important for anyone living with MCAS.
