Which autoimmune diseases cause night sweats
Which autoimmune diseases cause night sweats Autoimmune diseases are a diverse group of disorders in which the immune system mistakenly attacks the body’s own tissues. Among their many symptoms, night sweats are a common yet often overlooked sign that can indicate underlying immune dysfunction. Understanding which autoimmune conditions cause night sweats can aid in early diagnosis and effective management.
One of the most well-known autoimmune diseases associated with night sweats is systemic lupus erythematosus (SLE). Lupus is a chronic, multisystem disorder that can affect the skin, joints, kidneys, heart, and other organs. Patients with lupus often experience fever, fatigue, joint pain, and night sweats, especially during disease flares. The immune system’s overactivity and inflammation can trigger a persistent low-grade fever, which, combined with hormonal and metabolic changes, results in night sweats.
Rheumatoid arthritis (RA), primarily known for joint inflammation and deformity, can also present with systemic symptoms including night sweats. The chronic inflammation in RA leads to increased cytokine production, which can induce fever and sweating, particularly during active disease phases. Additionally, medications used to control RA, such as biologics and immunosuppressants, may contribute to sweating episodes.
Another autoimmune disorder linked to night sweats is Sjögren’s syndrome. This disease primarily targets moisture-producing glands, leading to dry eyes and mouth. However, systemic manifestations including fatigue, fever, and night sweats are common. The ongoing immune-mediated inflammation can disrupt normal temperature regulation and cause episodes of sweating, especially during periods of active disease.
Multiple sclerosis (MS), an autoimmune condition affecting the central nervous system, may also be associated with night sweats. While MS is primarily characterized by neurological symptoms like muscle weakness, vision problems, and numbness, some patients report autonomic dysfunction that affects temperature regulation. This dysautonomia can manifest as episodes of sweating or chills, often linked to disease activity or medication side effects.

Autoimmune thyroid diseases, such as Graves’ disease and Hashimoto’s thyroiditis, can also cause night sweats. Graves’ disease, which results in hyperthyroidism, increases metabolic rate and body temperature, often leading to excessive sweating, including at night. Conversely, Hashimoto’s thyroiditis typically causes hypothyroidism, which is less associated with night sweats but may still cause temperature regulation issues in some cases.
Lastly, vasculitis, a group of autoimmune diseases characterized by inflammation of blood vessels, can lead to systemic symptoms including night sweats. Conditions like giant cell arteritis or polyarteritis nodosa involve immune-mediated vessel damage that can impair circulation and thermoregulation, resulting in persistent or episodic night sweating.
In summary, several autoimmune diseases, through mechanisms such as systemic inflammation, autonomic dysfunction, or hormonal disturbances, can cause night sweats. Recognizing these symptoms in the context of other clinical signs can facilitate timely diagnosis and treatment, improving patient outcomes.
