Patients with allergic purpura should avoid consuming easily allergenic foods such as seafood, mangoes, and nuts, and reduce their intake of spicy and stimulating foods and cold drinks. Allergic purpura is a vasculitis associated with immune system abnormalities; improper diet may trigger or worsen symptoms. Seafood, mangoes, and nuts are common allergens that can induce immune responses, leading to recurring symptoms. Spicy and stimulating foods such as chili peppers and Sichuan peppercorns can irritate blood vessels, worsening skin purpura and gastrointestinal symptoms. Cold drinks may affect blood circulation, hindering recovery.
1. Common allergens: Seafood, mangoes, and nuts are common allergens that can trigger immune responses and cause recurring symptoms. Foreign proteins in seafood, urushiols in mangoes, and plant proteins in nuts can all act as allergens, stimulating the immune system to produce abnormal reactions and inducing or worsening purpura symptoms.
2. Spicy and irritating foods: Spicy foods such as chili peppers, Sichuan peppercorns, ginger, and garlic can irritate blood vessels, leading to vasodilation and increased permeability, which can worsen skin purpura and gastrointestinal symptoms. These foods may also irritate the gastrointestinal mucosa, causing abdominal pain, nausea, and other discomfort, thus affecting the recovery of the condition.
3. Cold drinks: Ice cream, chilled beverages, and other cold drinks can lower body temperature, affecting blood circulation and hindering the relief of purpura symptoms. Low temperature stimulation may cause vasoconstriction, worsening skin purpura and joint symptoms, while also affecting digestive function, which is detrimental to nutrient absorption and recovery.
4. High-protein foods: High-protein foods such as milk and eggs may increase the burden on the kidneys and hinder recovery. Patients with allergic purpura often have kidney damage, and excessive intake of high-protein foods may increase the burden on the kidneys and affect the recovery of kidney function.
5. Acidic foods: Citrus fruits, vinegar, and other acidic foods may irritate the gastrointestinal tract, causing discomfort and hindering recovery. These foods may irritate the gastrointestinal mucosa, causing abdominal pain, nausea, and other discomfort, thus affecting recovery.
Patients with allergic purpura should strictly adhere to dietary restrictions, avoiding allergenic foods, spicy and irritating foods, and cold drinks. They should also reduce their intake of high-protein and acidic foods. A reasonable diet helps control the condition and promote recovery. Regular checkups are essential to monitor changes in the condition and adjust the treatment plan as needed.
