Causes of Long-Term Low-Grade Fever in Rheumatoid Arthritis
I have rheumatoid arthritis and have recently experienced persistent low-grade fever, which has made me feel very unwell. In addition to the fever, my joints are painful and swollen, and at times, they even become so stiff that movement is difficult. I would like to know what exactly causes prolonged low-grade fever in rheumatoid arthritis.
Rheumatoid arthritis is a chronic, systemic autoimmune disease that primarily affects the joints but can also affect other parts of the body, such as the skin, eyes, and internal organs. Prolonged low-grade fever is one of the common symptoms in patients with rheumatoid arthritis, mainly caused by the following factors:
1. Inflammatory response: The fundamental nature of rheumatoid arthritis is inflammation. When the immune system mistakenly attacks the body's own tissues, it causes inflammation in the joints and surrounding tissues. This persistent inflammatory state can elevate body temperature, resulting in a low-grade fever.
2. Medication effects: Patients with rheumatoid arthritis may take glucocorticoids long-term, which can lead to hormonal imbalances in the body and subsequently cause prolonged low-grade fever.
3. Infections: Due to altered immune function, patients with rheumatoid arthritis may be more susceptible to infections, especially those receiving treatment with immunosuppressive agents. Infections can also cause fever.
4. Concurrent diseases: Conditions such as tuberculosis and hyperthyroidism can also lead to prolonged low-grade fever in patients with rheumatoid arthritis.
Maintaining healthy lifestyle habits, such as balanced nutrition, appropriate exercise, and sufficient rest, can also help alleviate symptoms.
