Drinking more water is not a cure for rheumatoid arthritis itself. Rheumatoid arthritis is a systemic autoimmune disease with unclear etiology and pathogenesis, which causes a series of inflammatory reactions in the joints due to damage caused by the immune system. At present, there is no way to achieve a complete cure for rheumatoid arthritis, patients need to use medication to treat the disease. Although rheumatoid arthritis patients not only need to actively treat the disease, but also need to do a good job of daily care and health care work, but drink more water this behavior has no therapeutic effect on rheumatoid arthritis disease itself. Moreover, if rheumatoid arthritis involves the kidneys, causing edema and proteinuria, drinking more water is not only not helpful, but may even aggravate the condition. Rheumatoid arthritis patients are advised to go to the rheumatology and immunology departments of regular hospitals for detailed consultation and standardized treatment as prescribed by doctors.
