Things You Need to Know About Food Allergy in The Elderly
Food allergies manifest as an immune system response to the ingestion of specific antigens, provoking signs and symptoms within moments of contact.
Even minute amounts can trigger difficulties, from gastrointestinal distress to hives, swelling, and airway obstruction.
Food allergies and sensitivities plague populations across the age spectrum, though seniors harbor greater vulnerability to harmful, even fatal consequences due to aging biology, complex health conditions, polypharmacy, and reduced physiological reserves.
According to US Census projections, food allergy prevalence in elders may swell to 20% or over 83 million affected by 2050.
Given the designation of Food Allergy Awareness Week from May 8-14, emphasis on risks, education, and prevention specific to the geriatric population proves most prudent and impactful.
This article aims to articulate the causes of age-related allergy increases, symptoms to notice, and strategies for mitigating threats to health, independence, well-being, and joy in later life.
Food Allergies Common in Seniors
Common food allergies in the elderly are as follows:
Seafood allergies are pretty common among the elderly, especially to crab, lobster, prawns, clams, bivalves, oysters, and scallops. Older adults often suffer from allergies caused by crustaceans and molluscs.
As with seafood allergies in general, the most severe reactions involve the respiratory system. Swelling of the throat, tongue, lips, and airways can lead to wheezing, coughing, shortness of breath, and even anaphylaxis.
Therefore, the elderly should be cautioned against eating any seafood after having an adverse response to one kind.
Although peanut allergies have proliferated of late, their underlying causes remain an enigma. According to studies, nearly 40% of seniors afflicted with peanut sensitivity may also react adversely to tree nuts, including almonds, hazelnuts, pecans, and pistachios.
This condition wields an augmented risk of anaphylaxis and is regarded as one of the most perilous allergies. In the event of a nut-induced allergic response, the potential for anaphylactic shock is substantially heightened.
Consequently, it has become standard practice to advise geriatrics with nut allergies of any kind to eschew all nuts.
Fruits and Vegetables
Oral allergy syndrome, also known as pollen-food allergy syndrome, designates the condition wherein distressing reactions to emerge upon ingesting certain fruits and vegetables, the most common triggers of food sensitivities in the aged. The immune system erroneously conflates proteins within these foods and airborne pollens, thereby cultivating the allergy.
In the vast majority of cases, an adverse response ensues upon consuming raw or undercooked varieties. Seniors may experience lip, palate, tongue, and esophageal irritation progressing to tingling, redness, swelling, blistering, and even anaphylaxis in rare instances.
Even while minor allergic responses to soy appear to be the norm, you always run the risk of experiencing more severe symptoms.
These symptoms include a hacking cough, itching, and issues with the stomach. Peanuts and soybeans are both a part of the same family of legumes.
Soy allergies are more common than peanut allergies, while peanut allergies are more common among persons who are allergic to soy.
Wheat intolerance stems from reacting adversely to gluten, a protein also found in barley, oats, rye, and allied grains. Celiac disease, similarly denoted gluten sensitivity, designates an allergy to gluten. Chronic inflammation within the digestive tract attenuates the body's capacity to absorb vital nutrients, a detriment amplifying with age.
Potential ramifications encompass intestinal gas and bloating, diarrhea, weight loss, nausea, vomiting, and malabsorption-induced nutritional deficiencies, all contributing to fatigue and weakness, particularly in elders.
Seniors experiencing celiac disease or gluten sensitivity thus frequently feel utterly drained from maintaining basic functions.
The Most Common Cause of Food Allergies in Seniors
Food sensitivities arise when the body's immune defenses erroneously perceive innocuous foods as threats, eliciting an exaggerated response and symptomatic inflammation.
In seniors, food allergies stem from an aging immune system exhibiting diminished discernment between harmless and hazardous substances, a diminution amplifying vulnerability.
Symptoms of Food Allergies in Older Adults
Common food allergy symptoms encompass hives, itching, swelling, impaired respiration, abdominal anguish, nausea, and vomiting. In severe instances, anaphylaxis can supervene, an life-threatening systemic allergic reaction.
Anaphylaxis causes a cascade of reactions across multiple organ systems, including a sudden, severe drop in blood pressure, shock with dizziness or fainting, a rapid, weak pulse, nausea, vomiting, abdominal pain, and respiratory failure. Without epinephrine or other emergent treatment, anaphylaxis proves immediately life-threatening.
How can older adults prevent food allergies?
To ensure that the elderly are safeguarded from food allergies, it is vital to be mindful and proactively take necessary measures. To this end, we have compiled some useful suggestions to help prevent food allergies among seniors:
Know your allergy history and symptoms
If harboring a history of food sensitivities or suspecting hidden food allergies, vigilance proves vital. Awareness of symptoms and triggers holds the key to prompt diagnosis, treatment, and management.
Discuss all prior allergic episodes, suspected foods, and symptoms experienced with healthcare providers and close companions, such as family members providing caregiving support.
Maintain written records enumerating the type of allergy, date of reaction, suspected triggers, and symptoms noticeable. Such documentation facilitates recognition and responses in future instances.
Avoid unnecessary food risks
Caution proves imperative when navigating the minefield of food consumption, particularly for those harboring a history of sensitivities or allergies. If uncertain regarding ingredients, preparation methods, or food safety, avoidance represents the sole strategy to minimize risk.
Common food allergens and triggers of anaphylaxis should likewise be strictly avoided, including peanuts, tree nuts, shellfish, milk, eggs, wheat, soy, and sulfited foods or additives. Cross-contamination during food preparation or processing/packaging also poses risks, necessitating the scrutiny of food labels.
According to the legal mandate, food producers must declare the presence of priority allergens including peanuts, tree nuts, eggs, fish, shellfish, milk, wheat, soy, and sulfited foods within ingredient listings and advisory statements. Accurate labeling will enable avoidance of reactive foods for those with sensitivities though limitations remain.
Communicate with caregivers
Clearly articulate a catalog of food allergies, intolerances, triggers, and safe/unsafe food options to any providing meal preparation, grocery shopping, or other nutrition-related support.
Caregivers must also receive training in recognizing symptoms of allergic reactions, especially anaphylaxis, and properly administering emergency medications such as epinephrine auto-injectors before being entrusted with responsibilities crucial to health, safety, and well-being.
Consult with healthcare professionals
For those contending with life-threatening food sensitivities, medical alert mechanisms prove imperative. An identification bracelet or card should be worn at all times, specifying the nature of allergy/allergies and contact information for emergency responders.
Solo emergency preparedness will not suffice, necessitating the development of a comprehensive management plan with healthcare professionals. This plan optimizes safety, capability, and quality of life based on the type, severity, and progression of allergies as well as personal priorities, values, and life goals.
In summary, food allergies germinating or exacerbating with age hold the potential for detriment, despite senior years representing a time for wisdom and an enriched living experience. Yet through diligent prevention, integrated management, and persistence in optimizing health, well-being, and quality of life, elders can continue adventuring and thriving rather than merely surviving.
