Rheumatoid arthritis may be inherited

Some people with rheumatoid arthritis in their families and some patients with rheumatoid arthritis who have children are worried.
"Grandma and mother have RA, but will I also have it?"
"Is RA inherited in children?"

It is not always inherited, but it can be inherited if it is more likely to develop.

What is the cause of rheumatoid arthritis?

The cause of rheumatoid arthritis has not yet been clarified, but it is thought to be caused by a combination of several "genetic factors" and the addition of "environmental stimuli" such as viral infection, stress, and smoking. I will.

Inheritance of genes that are prone to develop?

There is a family with frequent cases of rheumatoid arthritis, and if one of the identical twins (genes are 100% identical) has rheumatoid arthritis, there is a 15-30% chance that the other will also have rheumatoid arthritis. It is speculated that genetic factors are involved in the onset of rheumatoid arthritis.

In addition, by analyzing the genes of patients with RA, the existence of some genes (disease susceptibility genes) that make them more likely to develop RA has been clarified.

Given these facts, I think there is a possibility of inheritance as to whether or not rheumatoid arthritis is likely to occur .

However, as shown at the beginning, it is thought that rheumatoid arthritis develops not only due to heredity but also due to environmental stimuli, and just because there is a genetic component does not mean that rheumatoid arthritis develops...

If you have a blood relative who has rheumatoid arthritis, seeing a hospital early if you experience joint pain may lead to early diagnosis and treatment of rheumatoid arthritis.

Early treatment is also more likely to slow the progression of symptoms and achieve a condition free of joint pain and bone destruction.

Can it be prevented?

If you have a genetic component, you may be wondering if there is a way to prevent the onset.

Oral care and smoking cessation are important for prevention

The cause of rheumatoid arthritis may not yet be known and there is no way to prevent it completely, but recent studies have shown that periodontal disease and smoking are associated with the development of rheumatoid arthritis. It's coming. Oral care and smoking cessation are important not only in health care but also in controlling the onset of rheumatoid arthritis.

Don't worry too much about your genetic potential for rheumatoid arthritis, avoid smoking, which is a particular risk, and seek early medical attention if you experience joint pain.
