Although gout is often mistaken for rheumatoid arthritis, learn the differences associated with the causes, symptoms, and treatments below.
Gout is often mistaken for rheumatoid arthritis due to various similarities. However, these diseases have differences associated with the causes, symptoms, and treatment options.
What is rheumatoid arthritis?
Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by pain and inflammation in more than one joint (polyarthritis) of the hands and feet.
- It is an autoimmune disease, where the immune system of the body attacks healthy cells, resulting in inflammation of the membrane lining the joints (synovial membrane) and eventual damage to joint tissue.
- RA affects other organs, such as the skin, heart, lungs, and eyes, resulting in side effects.
The annual incidence of RA is approximately three cases per 10,000 people worldwide.
What is gout?
Gout is a common form of inflammatory arthritis.
- It is a condition associated with high uric acid levels in the blood.
- These uric acid forms crystals that accumulate around the joints, leading to sudden and severe pain and swelling.
Gout commonly affects the joints of the big toe and is found in joints of the knee, ankle, foot, hand, wrist, and elbow.
What causes rheumatoid arthritis?
Rheumatoid arthritis (RA) is an autoimmune disease where the body’s immune system attacks its healthy cells and tissues; however, some of the contributory factors to rheumatoid arthritis are:
- Genetic factors
- Some viruses and infectious agents are potential contributory factors
- Sex hormones may play a role in causing RA
- Immune system disorder
- Age between 35 and 50 years
- High-risk ethnic backgrounds, such as Native American
- Women are affected more often than men
- Family history of RA
- Tobacco smoking
What causes gout?
A high amount of uric acid in the blood is the main cause of gout. Humans synthesize uric acid from purines found in certain foods and drinks. The uric acid thus formed is eliminated by the kidneys through urine.
When the body produces excess uric acid or when the kidney fails to eliminate the uric acid, the resultant uric acid crystals can concentrate in the joints, resulting in gout. However, many people with higher uric acid do not seem to have uric acid deposition in soft tissues, indicating genetic predisposition.
Gout can affect anyone, especially men and menopausal women. Men are at three times more risk of acquiring gout than women because they have higher uric acid levels most of their lives. Women reach this amount of uric acid levels after menopause.
Some medical conditions that can increase the risk of getting gout include:
- Congestive heart failure
- Family history of gout
- Hypertension (high blood pressure)
- Kidney disease
Other factors likely to increase a person’s risk of getting gout include:
- Consuming a diet high in animal proteins
- Heavy alcohol drinking
- Being on diuretics
- Some medications
The early occurrence of gout is often due to lifestyle factors that promote high levels of uric acid in the body.
What Is Rheumatoid Arthritis (RA)? Symptoms, Treatment, Diagnosis
12 common symptoms of RA
The most common symptoms of rheumatoid arthritis (RA) include morning stiffness and symmetrical symptoms. At times, symptoms worsen, which are called flares, and when a person recuperates from the symptoms, it is called remission.
