"What Causes Chronic Low-Grade Fever and Anemia?"

Long-Term Low-Grade Fever and Anemia: Possible Causes and Suggested Treatments

Long-term low-grade fever accompanied by anemia may be associated with malnutrition, chronic infections, rheumatic immune diseases, and other underlying conditions. It is recommended that patients promptly consult the hematology department of a hospital, where they can undergo tests such as bone marrow aspiration and blood routine examination under the guidance of a physician for a definitive diagnosis. The potential causes and corresponding suggestions are outlined below:

1. Malnutrition

Prolonged food pickiness,偏食, or the presence of gastrointestinal disorders like gastritis and gastric ulcers can lead to inadequate nutrient absorption, resulting in malnutrition. To repair damaged tissues, the body may respond with long-term low-grade fever. It is advised that patients adjust their diets to ensure balanced nutrition, incorporating fresh fruits and vegetables like apples and spinach.

2. Chronic Infections

Infection with Mycobacterium tuberculosis can cause chronic infections. These bacteria proliferate within the body, potentially damaging the bone marrow if present there, leading to long-term low-grade fever. Timely medical examination is crucial, and upon diagnosis, patients may be prescribed medications like Rifampicin and Isoniazid under medical supervision.

3. Rheumatic Immune Diseases

Persistent low-grade fever accompanied by joint pain and fatigue may indicate rheumatic immune diseases such as Systemic Lupus Erythematosus. This disease disrupts the immune system, triggering the production of inflammatory factors that stimulate the body's temperature regulation center. Patients are advised to seek medical attention promptly and may be prescribed medications like Methylprednisolone and Dexamethasone acetate.

Additionally, conditions like malignancies can also cause long-term low-grade fever. Malignancies may arise from genetic predisposition or prolonged exposure to radioactive substances. Tumor cells can cause symptoms like low-grade fever and fatigue. Maintaining a positive mindset and consuming nutritious foods like eggs and milk is recommended.
