Persistent constipation: frequent constipation, diarrhea or smelly feces. 3. Face is like a dish: rough skin, easy to grow acne and spots. 4. Weight change: weight gain or sudden weight loss, but no weight loss. 5. It is easy to suffer from insomnia: insomnia, headache, fatigue and dizziness. 6. Loss of appetite: nausea, stomachache, indigestion and burping.
