Firstly, rheumatoid arthritis belongs to autoimmune diseases and is a chronic condition. The main symptoms include symmetric pain in multiple joints across the body, accompanied by morning stiffness, which is why joint pain occurs and is the most common symptom. The onset is slow for most people, but some experience an acute onset, with joint mobility issues appearing within a few weeks or days. Therefore, this disease cannot be cured; it can only be managed with medications to control symptoms, delay the deformity of joints, reduce disability rates, and enhance the quality of life, which are the objectives of comprehensive treatment. It is important to avoid exposure to cold and fatigue in daily life, avoid contact with cold water, keep warm, also avoid raw and cold foods, spicy and irritating foods, and eat more light, easy-to-digest, and high-protein foods to boost the immune system.
