Sleep deprivation. Sleep deprivation is the condition of not having enough sleep; it can be either chronic or acute. A chronic sleep-restricted state can cause fatigue, daytime sleepiness, clumsiness and weight loss or weight gain. It adversely affects the brain and cognitive function.
Because most inflammatory forms of arthritis are systemic (meaning they affect the entire body), other symptoms related to inflammation may occur in other parts of the body. Depending on the specific form of arthritis, these symptoms could include skin rashes, eye inflammation, hair loss, dry mouth and fever.
Inflammatory arthritis, such as lupus arthritis or RA, involves soft and spongy swelling of the joint, tenderness and stiffness. The painful swelling that occurs in RA, may eventually cause joint deformity and bone erosion. The most common non-inflammatory arthritis is osteoarthritis.
