Introduction

A rare condition called mastocytosis is typified by an abnormal build-up of mast cells in the skin, bone marrow, and internal organs, among other tissues. These cells contribute to inflammation and are in charge of allergic reactions. Excessive activation of mast cells in people with mastocytosis can cause a variety of symptoms, such as flushing, itching, abdominal discomfort, anaphylaxis, and even bone pain. Although there isn't a treatment for mastocytosis, people who are affected can greatly enhance their quality of life by treating their symptoms with dietary and lifestyle changes. The goal of these modifications is to reduce the number of stimuli that result in mast cell degranulation, histamine release, and other inflammatory mediators.¹

Understanding mastocytosis and its triggers

There are other types of mastocytosis, such as cutaneous mastocytosis, which mostly affects the skin, and systemic mastocytosis, which affects multiple organs. Whatever the kind, the development of symptoms is largely dependent on mast cell activation. There is a broad range of triggers that can activate mast cells, such as physical stimuli, environmental factors, drugs, food, and stress.

Exercise, friction, temperature changes, and other physical stimuli can all cause mast cell degranulation. In a similar vein, external stimuli such as potent scents, insect stings, and stress can also trigger mast cell inflammatory secretion. Opioids, certain antibiotics, and non-steroidal anti-inflammatory drugs (NSAIDs) are among the pharmaceuticals that might cause mast cell activation. Apart from external stimulants, diet is a vital factor in controlling the symptoms of mastocytosis because numerous foods have the ability to either directly activate mast cells or elevate the body's histamine levels.²

Lifestyle modifications for mastocytosis

To effectively manage mastocytosis, one must recognise and stay away from triggers that cause mast cell activation. Modifying one's lifestyle is crucial to preventing symptoms and enhancing one's general quality of life. The following are some crucial lifestyle modifications for people with mastocytosis:³

• Preventing severe heat and physical injury:
  Mast cell degranulation can be brought on by physical stimuli, including heat, cold, or friction. It is recommended that patients with mastocytosis avoid prolonged exposure to intense heat or cold. When it comes to cutaneous mastocytosis in particular, wearing loose-fitting, breathable clothing can help minimise skin irritation. While moderate exercise has been shown to improve general health, vigorous exercise that produces friction or overheating should be used with caution
• Reduction of stress:
  Mast cell activation is known to be triggered by psychological stress. Deep breathing exercises, yoga, and meditation are examples of relaxation practices that can help reduce stress and stop symptom flare-ups. Reducing stress can also be accomplished by creating healthy coping strategies, keeping a regular sleep pattern, and asking for help from friends, family, or professional counsellors
• Steer clear of recognised environmental triggers:
  Strong scents, cleaning agents, and insect bites are among the environmental elements that people with mastocytosis should be aware of. Reaction times can be reduced by employing unscented or hypoallergenic items, keeping living areas well-ventilated, and avoiding harsh chemicals. For certain individuals, insect bites and stings, especially those from bees and wasps, can be fatal, so it's critical to exercise caution when outside and have emergency supplies on hand, such as epinephrine auto-injectors, just in case
• Medication administration:
  Certain drugs have the potential to activate mast cells or obstruct the effects of mastocytosis therapies. In order to choose safe medications and stay away from ones that can make their symptoms worse, patients should consult closely with their healthcare experts. Antihistamines and mast cell stabilisers are commonly prescribed drugs to treat the symptoms of mastocytosis. In certain situations, biologics or corticosteroids are also used to reduce inflammation

Dietary modifications 

Making dietary changes is essential for controlling mastocytosis since some foods can cause mast cell degranulation or raise the body's histamine levels. As each patient may react to meals in a different way, a food diary might be a useful tool for pinpointing triggers. Although each person reacts differently, there are some common dietary recommendations for mastocytosis patients: ⁴

• A diet low in histamine:
  A diet low in histamine is beneficial for many people who have mastocytosis. Eating foods high in histamine can aggravate symptoms because mast cell activation releases the chemical histamine. Avoid foods high in histamine, such as aged cheeses, fermented foods (like sauerkraut, soy sauce, and vinegar), processed meats, alcoholic drinks (like red wine and beer), and some types of fish (including tuna, sardines, and mackerel). Histamine levels in fresh, unprocessed foods are often lower and therefore better
• Preventing the ingestion of histamine liberators:
  Despite not having a lot of histamine in them directly, some foods might trigger the body to release histamine that has been stored. Tomatoes, strawberries, citrus fruits, chocolate, nuts, and citrus fruits are examples of foods that are considered histamine liberators. If some meals make patients sick, they might need to limit or avoid them
• Food triggers:
  Sensitive people may experience mast cell degranulation due to dietary ingredients other than histamine. Food additives like artificial colouring and preservatives, hot foods that might irritate the gastrointestinal tract, and foods high in sulfites (like wine and dried fruits) are common offenders. The diet must be customised to each patient's tolerance level because triggers can differ between them
• Adopting a nutrient-rich, balanced diet:
  To support general health, it may be necessary to remove some foods from the diet, but it's still critical to maintain a balanced intake of nutrients. As tolerated, the diet should include whole grains, lean meats and poultry, fresh produce, and healthy fats. Ensuring that nutritional requirements are satisfied while reducing trigger foods can be facilitated by working with a dietitian who specialises in low-histamine diets or mastocytosis
• Water balance and digestive health:
  It's crucial for people with mastocytosis to stay hydrated and drink a lot of water, especially if they're having gastrointestinal symptoms like bloating, diarrhoea, or abdominal pain. Drinking enough water can ease stomach discomfort and help control digestion. Probiotics and other dietary supplements may occasionally help to support gut health, but they should only be used sparingly and under a doctor's supervision

Conclusion

The overactivation of mast cells in mastocytosis, a chronic disorder, can cause a variety of symptoms. Changes in food and lifestyle are essential for managing symptoms and enhancing quality of life, even if there is no known cure. A low-histamine diet, stress management, and avoiding recognised triggers can help people with mastocytosis lessen the frequency and intensity of their symptoms. Working together with dietitians and healthcare professionals will help create a customised plan that will address the mental and physical aspects of having mastocytosis.
