I'm sorry to hear you're feeling low on energy and have lost your appetite after a long course of antibiotics. This can happen because antibiotics may disrupt the natural balance of bacteria in your gut, which can affect digestion and nutrient absorption, potentially leading to fatigue and decreased hunger.

Here are some steps you can consider:

• Monitor your symptoms: If low energy and poor appetite persist beyond a few days or worsen, it’s important to seek medical advice.
• Stay hydrated: Drink plenty of fluids to support your recovery.
• Eat small, balanced meals: Even if you don’t feel hungry, try to eat nutrient-rich foods in smaller portions to help maintain energy.
• Probiotics: Sometimes, taking probiotics after antibiotics can help restore healthy gut bacteria, but consult your doctor before starting any supplements.
• Review medications: Since you mentioned a new allergy to eggs and antibiotic use, inform your doctor about all your symptoms and medications to rule out any side effects or allergic reactions.

Given your situation, I strongly recommend consulting an allergist or your primary care doctor. They can evaluate your symptoms thoroughly, check for any complications from antibiotics, and guide you on appropriate treatment or dietary adjustments. If your energy levels continue to decline or you develop new symptoms, seek medical attention promptly.To narrow down potential causes, we will need some more information.I understand you're feeling low on energy and have a reduced appetite after taking antibiotics for an egg allergy.
