Why can patients with rheumatoid arthritis predict the weather?

In rainy weather, the phenomenon of temperature drop, air pressure drop and humidity increase often occurs, which will lead to the aggravation of local pain in patients with rheumatoid arthritis. Mainly due to the dysfunction of the patient's joints and surrounding blood vessels and nerves, the blood vessels relax and contract and the skin temperature rises and falls slowly. Therefore, patients with rheumatoid arthritis will be more sensitive to weather changes.

Weather changes, such as cooling, cooling, cooling and increasing wind speed, can be seen and perceived by ordinary people, and physiological mechanisms in the body will also make normal adjustments to this change. For example, when it rains, the air pressure will generally decrease and the humidity will increase, so that the liquid in the cells of healthy people can seep out by themselves, resulting in an increase in urine volume to adapt to the weather changes.

For arthritis patients, due to the existence of diseased tissues, the liquid in the cells can not be discharged in time with the change of weather, which leads to the cell pressure in the diseased area higher than that in the surrounding normal tissues, which will cause swelling and pain in the diseased area. This is one of the reasons why arthritis patients can predict weather changes.

Five years ago, a foreign study involving 8 10 patients in six European countries showed that the changes of air humidity and temperature were related to joint pain. And the colder the weather, the greater the influence of air humidity on joint pain. What is the reason for the current speculation? The sudden drop of air pressure brought by the weather will affect the pressure level of joints, make joints edema and compress the painful nerves.

This is also the reason why I have repeatedly stressed that all patients and friends must pay attention to cold-proof and warm-keeping measures, which will help control the disease and alleviate the pain. It should be noted that the weather only affects the fluctuation of arthritis symptoms, not the cause of osteoarthritis. Pay attention to keep warm and add clothes in time; Ideally, move to a warmer place with less humidity; Wear protective gear, knee pads to protect knee joints, gloves to protect finger joints, etc. Moderate exercise can increase local blood flow of joints and relieve pain; Have a positive attitude? Negative emotions will increase the sensitivity to pain; If necessary, you can consult a doctor to adjust the medication plan.
