What are some things that cause Raynauds disease?

* Autoimmune diseases: Raynaud's disease is often associated with autoimmune diseases, such as lupus, scleroderma, and rheumatoid arthritis. In these diseases, the immune system mistakenly attacks the body's own tissues, which can lead to inflammation and damage to the blood vessels.

* Smoking: Smoking is a major risk factor for Raynaud's disease. The chemicals in cigarettes can damage the blood vessels and make them more likely to spasm.

* Certain medications: Some medications, such as beta-blockers, ergotamine, and chemotherapy drugs, can cause Raynaud's disease or make it worse.

* Exposure to cold: Cold temperatures can trigger Raynaud's attacks. This is because the cold causes the blood vessels to constrict, which can lead to a lack of blood flow to the fingers and toes.

* Repetitive trauma: Repetitive trauma to the hands or feet, such as from playing a musical instrument or using vibrating tools, can also cause Raynaud's disease.
