This article explains how to recognize common signs of a weakened immune system—such as frequent or lingering infections, slow-healing wounds, ongoing fatigue, repeated sinus or chest infections, digestive upsets, or recurrent thrush—and what they may mean for your health. It outlines factors that can lower immunity (including stress, poor sleep or nutrition, certain medications, and chronic conditions) and highlights when to seek medical advice, especially for persistent symptoms, high fevers, or unexplained weight loss. Readers will find practical, evidence-informed steps to support immune health—like vaccination, hand hygiene, healthy sleep, balanced nutrition, and stress management—plus guidance on what clinicians might evaluate. Designed for patients and caregivers, it offers clear, reliable information to help you track symptoms and start informed conversations with your healthcare provider.
