Our bodies give small signals that something might be wrong. Here are four symptoms to watch for: 1.Scalloped Tongue — Wavy edges may indicate swelling from sleep apnea, hypothyroidism, or excess salt intake. Persistent cases should be checked by a doctor. 2.Dark Circles — Often caused by lack of sleep, dehydration, stress, or allergies. Sudden or worsening circles may signal a need for lifestyle adjustments. 3.Persistent Dry Skin — Can result from eczema, hypothyroidism, or nutrient deficiencies. If moisturizing doesn’t help, seek medical advice. 4.Cold Hands and Feet — May suggest poor circulation, Raynaud’s disease, or anemia. Frequent cold extremities warrant a doctor’s visit
