DR🦐 Shellfish Allergy – Why it can appear suddenly!
• 🦞 Prawns, crab, lobster & shellfish contain a protein called tropomyosin.
• ⚠️ In some people, the immune system treats this protein as a dangerous substance, causing an allergic reaction.
• 🤧 Common symptoms include
– Itching
– Skin rashes
– Swelling of lips or eyes
– Breathing difficulty
• 🚨 In rare cases, the reaction can become severe (anaphylaxis) and may even be life-threatening.
• 👶 Why could you eat it when you were young but not now?
Your IgE allergy system matures over time, and repeated exposure can sensitize your immune system.
• 📈 That means the body may develop an allergy later in life, even if you tolerated shellfish before.
• 🥜 Interestingly, some allergies like peanut allergy may reduce with early exposure in childhood.
• 🦐 But shellfish allergy is different — repeated exposure may actually increase the reaction, not reduce it.
• ⚠️ So don’t try “testing it again” repeatedly if you already had an allergic reaction.

✨ Key Takeaway:
If you develop shellfish allergy as an adult, avoid repeated exposure and consult a doctor.
