Elevated Body Temperature: Causes and Concerns - Family Medicine

Elevated body temperature, or fever, can be a sign of various underlying health issues, and understanding its causes is essential for addressing any potential concerns. In your case, you mentioned experiencing high body temperature at night, cold extremities, eye strain, and fatigue, along with a recent diagnosis of rheumatoid arthritis. Let’s explore these symptoms and their possible connections.

Firstly, elevated body temperature is typically defined as a core body temperature above the normal range of approximately 36.1°C to 37.2°C (97°F to 99°F). Fever can result from infections, inflammatory conditions, autoimmune diseases, and other medical issues. In your situation, the recent diagnosis of rheumatoid arthritis (RA) is particularly relevant. RA is an autoimmune disorder characterized by chronic inflammation of the joints, which can lead to systemic symptoms, including fever and fatigue. The inflammation associated with RA can cause the body to release pyrogens, substances that induce fever, leading to elevated body temperature.

The coldness of your hands and feet, despite having a high body temperature, could be attributed to several factors. One possibility is that your body is diverting blood flow to vital organs in response to inflammation or fever, resulting in reduced circulation to the extremities. This phenomenon is known as peripheral vasoconstriction and can occur during fever as the body attempts to maintain its core temperature. Additionally, conditions like anemia, which can be associated with chronic inflammatory diseases, may also contribute to cold extremities.

Eye strain and fatigue are common complaints that can arise from various factors, including prolonged screen time, lack of sleep, or even the stress of managing a chronic illness like RA. The inflammation and discomfort associated with RA can lead to increased fatigue, as your body expends energy to combat the inflammatory processes. Furthermore, if you are experiencing sleep disturbances due to pain or discomfort from RA, this could exacerbate feelings of fatigue and eye strain.

Given your symptoms and recent diagnosis, it is crucial to monitor your condition closely. Here are some considerations and recommendations:
1. Consult Your Healthcare Provider: It is essential to discuss your symptoms with your healthcare provider, especially since you have a diagnosis of rheumatoid arthritis. They may want to evaluate your current treatment plan and consider whether your symptoms are related to your RA or if there is another underlying issue.

2. Monitor Your Symptoms: Keep a detailed record of your symptoms, including the frequency and intensity of your elevated body temperature, cold extremities, eye strain, and fatigue. This information can help your healthcare provider make informed decisions regarding your care.

3. Manage Inflammation: If your elevated body temperature is related to inflammation from RA, your doctor may recommend anti-inflammatory medications or disease-modifying antirheumatic drugs (DMARDs) to help manage your symptoms.

4. Lifestyle Adjustments: Consider making lifestyle changes that may help alleviate some of your symptoms. This could include ensuring you get adequate rest, managing stress through relaxation techniques, and taking regular breaks from screens to reduce eye strain.

5. Stay Hydrated: Fever can lead to dehydration, so it’s important to drink plenty of fluids, especially if you are experiencing elevated body temperature.

6. Regular Follow-ups: Regular check-ups with your healthcare provider are essential for managing chronic conditions like RA. They can help monitor your symptoms and adjust your treatment plan as necessary.

In conclusion, elevated body temperature can be indicative of various health issues, particularly in the context of rheumatoid arthritis. It is important to approach your symptoms holistically and work closely with your healthcare provider to ensure appropriate management and care.
