The exact cause of rheumatoid arthritis is unknown, but it is believed to be a combination of genetic, environmental, and immune system factors. Some potential causes and risk factors include:
1. Genetic predisposition: People with a family history of rheumatoid arthritis are more likely to develop the condition.
2. Environmental factors: Certain environmental factors, such as smoking, exposure to pollutants, and infections, may trigger the development of rheumatoid arthritis in individuals who are genetically predisposed.
3. Autoimmune response: Rheumatoid arthritis is considered an autoimmune disease, where the immune system mistakenly attacks the body's own tissues, leading to inflammation and joint damage.
4. Hormonal factors: Women are more likely to develop rheumatoid arthritis than men, suggesting that hormonal factors may play a role in the development of the disease.
5. Age: Rheumatoid arthritis most commonly develops in people between the ages of 30 and 60, although it can occur at any age.
6. Obesity: Being overweight or obese can increase the risk of developing rheumatoid arthritis and may also worsen symptoms in individuals who already have the condition.
7. Infections: Some infections, such as certain viruses and bacteria, have been linked to the development of rheumatoid arthritis in some individuals.
It is important to note that while these factors may increase the risk of developing rheumatoid arthritis, not everyone with these risk factors will develop the condition. Additionally, the exact cause of rheumatoid arthritis may vary from person to person.

Genetic Factors:
- HLA-DR4 and HLA-DR1: Certain human leukocyte antigen (HLA) genes, particularly HLA-DR4 and HLA-DR1, are strongly associated with an increased risk of rheumatoid arthritis.
- Other genetic variations: Multiple other gene variants have been linked to rheumatoid arthritis, but their exact roles are still being investigated.
Environmental Factors:
- Smoking: Smoking cigarettes significantly increases the risk of developing rheumatoid arthritis and worsens disease activity.
- Obesity: Excess weight and obesity have been associated with an increased risk of rheumatoid arthritis.
- Infections: Certain infections, such as Epstein-Barr virus and parvovirus B19, have been linked to an increased risk of developing rheumatoid arthritis.
- Trauma or injury: Physical trauma to joints may trigger or worsen rheumatoid arthritis in some individuals.
- Exposure to silica: Occupational exposure to silica dust has been associated with an increased risk of rheumatoid arthritis.
Hormonal Factors:
- Female sex: Women are more likely to develop rheumatoid arthritis than men.
- Hormonal changes: Pregnancy and menopause may trigger or worsen rheumatoid arthritis in some women.
Other Factors:
- Age: The risk of rheumatoid arthritis increases with age.
- Family history: Having a family member with rheumatoid arthritis also increases the risk.
- Stress: While not a direct cause, chronic stress may worsen the symptoms of rheumatoid arthritis.
- Diet: Certain dietary factors, such as low vitamin D levels, may be linked to an increased risk of rheumatoid arthritis.
Note: The exact causes of rheumatoid arthritis are complex and not fully understood. It is likely a combination of genetic, environmental, and other factors that trigger an autoimmune response leading to inflammation and joint damage.
