Why rheumatoid arthritis patients have stiffness in the morning, as rheumatoid arthritis patients, is not very interested in understanding why rheumatoid arthritis patients will be stiff in the morning joints, stiffness in the morning refers to the morning after waking up stiff fingers, can not make a fist, the phenomenon of inconvenience, must be active for a considerable period of time before the gradual easing of the stiffness of the situation. Early morning stiffness is a very prominent clinical symptom of rheumatoid arthritis patients, and now the diagnostic criteria for rheumatoid arthritis will be early morning stiffness as one of the criteria, so its significance is quite important. Early morning stiffness is referred to as morning stiffness, sometimes not necessarily limited to the hands, other joints and muscles of the whole body have a long period of time after resting stiffness, gradually relieved after activities. Foreign countries in the diagnosis of rheumatoid arthritis in the morning stiffness time is set at l hours or more, but some people think that can not be so generalized, such as some domestic experts combined with China’s own environmental factors and other circumstances, that more than 0.5 hours or more also has significance. The longer the duration of morning stiffness, the more serious the disease is, or in a period of progressive activity. After treatment, the morning stiffness time is shortened, which just means that the treatment has achieved certain effect and can be continued. The morning stiffness time is a more sensitive indicator, which is very important for diagnosing or judging the progress of the disease, and should not be underestimated for such a simple symptom. Why rheumatoid arthritis patients have a stiff feeling in the early morning, the following is the cause of rheumatoid arthritis patients morning stiffness, morning stiffness is due to the joints with lesions, especially small joints, after a night of inactivity, the joints inside and outside the tissues due to poor circulation and edema, the loss of the normal suppleness, which affects the normal activities of Gong function. After a period of activity, the edema disappears due to the improvement of blood circulation, and the tissues regain their suppleness, thus the joint activities tend to be flexible again, and the phenomenon of morning stiffness disappears. Those with obvious circulatory disorders and severe edema need more time to recover from the edema, thus the early morning stiffness lasts longer. Why do patients with rheumatoid arthritis tend to have poor circulation after rest? This is related to the pathologic changes in the disease. The basic pathologic changes in rheumatoid arthritis are synovitis and vasculitis. In synovitis the synovium and joint capsule become congested, edematous, thickened, and roughened. Granulation tissue forms, causing impaired intra-articular circulation. Glomerulitis of the periarticular tissues leads to narrowing of the vascular vessels, causing poor extra-articular circulation. During Activity. Blood and lymphatic fluid can still flow normally, and it is easy to stagnate poorly if you stay still for a long time. These are one aspect that rheumatoid arthritis patients should be aware of. The time of morning stiffness relies mainly on the patient’s own measurement, and should be observed as carefully as possible to calculate the time accurately, and make a good daily record. For example, getting up at 6 a.m. and feeling unable to make a fist． Can not wring the hand towel, daily activities, at 7:00 a.m. feel can make a fist. Then the morning stiffness time is 1 hour.
