, or RA, is a chronic inflammatory of the joints which gradually decreases and disables joint movements. Additionally it is known to influence an individual symmetrically. As an example, inflammation and pain of knee joints will appear together in the left and right leg. A é um sistema muito complexo. É composto por unidades funcionais muito pequenas, chamadas células.

Sistema imunitário

Theses cells organize into different body parts to carry out several activities, while it’s the joints in the hands or the blood flow. They’re also involved in the human immune system. The blood keeps the immune system of the body via its own white blood cells, which can be anti-bodies. They work towards fighting the foreign bodies or “invaders” that cause disease in the human body. Sometimes the radicals, famous for its immune solutions, “wrongly” assault the “good tissues” in the body.

O corpo responde à condição e como mecanismo de defesa faz com que a área atacada inflame. Uma dessas doenças crónicas e auto-imunes é que a artrite reumatóide. É um tipo grave de doença causada pela inflamação das articulações ou onde dois ossos se encontram. Enquanto num caso normal de artrite que o paciente se queixa apenas de inflamação das articulações, a artrite reumatóide danifica e deforma a articulação, incapacitando as suas funções, particularmente a sua capacidade de se mover.


RA leaves the inflamed joints swollen, stiff, and painful. In severe cases of RA, the delicate tissues holding the , the tendons, ligaments, and fascia become affected. RA, in actuality, damages the cartilages or the soft, elastic tissues causing movement of the bones, too.

A artrite reumatóide pode até estender-se a órgãos como o baço e in the body if deprived of appropriate health therapy. At this stage, someone will face different problems like low blood count, loss, fever, and dryness in the mouth and eyes. RA starts with inflammation of joints, mainly the internal lining called the synovial tissue. Synovial cells are the instance that holds the bones at the joint. The case comprises synovial fluid, which divides the cartilages between to help smooth motion. When the anti-bodies attack the synovial tissues, the area inflames and the joints create pain, swell, and become stiff.

Nota final

Gradually, the synovial lining thickens. As the condition deteriorates, it releases fluids or enzymes which destroy cartilages and bones, reducing flexibility and leaving the joints deformed. Over a time period, it becomes hard to move that joint. Rheumatoid arthritis can affect anyone, at any age, though, it’s found more commonly in women than men. Another thing to be noted is that the reason behind RA need not necessarily be genetic elements. This disease, thus far, isn’t known to have a permanent cure. In certain cases of RA, the disease remains dormant for a long period and strikes again. This is also referred to as a flare-up. Medical treatment, together with good and exercise regime, would help one to deal with rheumatoid arthritis.
