Weighing in on joint disease
Osteoarthritis is a common form of joint inflammation. A healthy diet, the right supplements, and joint-friendly exercise can help relieve this painful condition.
Chances are, you know someone who has arthritis. Arthritis affects more than 4 million people in Canada. Of the more than 100 diseases and conditions that fall under this category, osteoarthritis is the most prevalent form of joint inflammation.
What is osteoarthritis?
The ends of our bones are covered with an elastic material called cartilage. Cartilage allows our joints to move smoothly and acts like a shock absorber. Osteoarthritis erodes cartilage from the joints. This results in more bone-on-bone interaction, along with an increase in pain, stiffness, and swelling.
Osteoarthritis occurs in hands, hips, knees, feet, spine, and joints that may have been damaged by injury or other diseases such as rheumatoid arthritis.
What are the symptoms?
In general, the symptoms of osteoarthritis develop slowly over months or years.
The progression looks something like this.
What causes osteoarthritis?
“Aging and weight are the two biggest causes for osteoarthritis,” says Dr. Alice Klinkhoff, medical director for the Arthritis Society. “Then there are inherited factors and injuries that predispose people to cartilage damage. Finally, there is the unknown, which is why people are doing research to try to prevent osteoarthritis.”
Klinkhoff is referring to the risk factors for developing osteoarthritis. There are two kinds: inherent, which are factors we can’t do anything about, and external, which are factors we can control to minimize the risk.
Age: As we age, we increase our chances of developing osteoarthritis. Loss of muscle mass, thinning of joint cartilage, and loosening of ligaments all contribute to increased risk.
Genetics: Researchers are finding that family history is an important factor in our predisposition to osteoarthritis.
Complications from other forms of arthritis: Damage as a result of inflammation from other types of arthritis can leave the joint vulnerable to secondary osteoarthritis.
Sex: Being a woman increases your chance of developing osteoarthritis. Researchers aren’t clear as to why that is, but they suspect it may be linked to the hormone estrogen.
Weight: Being overweight increases the risk of developing osteoarthritis and will exacerbate your condition and increase your pain.
Lack of exercise: Being sedentary can result in weight gain, increased joint pain, reduced joint mobility, depression, and increased risk for other chronic diseases. Normal wear and tear alone does not cause the joints to degenerate. Regular activity is good for the joints and does not cause osteoarthritis.
Environmental factors: New research has linked synthetic chemicals to an increased risk of developing osteoarthritis (see sidebar on page 57).
Making healthy choices
There’s a lot we can do to reduce our risk of developing osteoarthritis and to improve quality of life when living with osteoarthritis.
Eat a healthy diet
A balanced diet will help achieve and maintain a healthy weight. It may also provide the energy you need for daily activities.
Some general guidelines for a balanced diet include
Exercise strengthens the muscles around the affected joints, providing support and protection. Exercise also increases joint mobility, reduces fatigue and pain, and helps ward off depression.
Winter can pose additional challenges to someone with osteoarthritis. Here are some tips for exercising during the winter, for those who are willing to brave the cold.
If going outdoors in the winter isn’t your thing, here are some other ways to keep moving.
Consider complementary therapies
Some complementary therapies shown in recent research to improve quality of life while living with osteoarthritis are:
You should always consult your health care practitioner before embarking on changes to diet or lifestyle, including complementary therapies.
Did you know?
Environmental factors: PFOA and PFOS
PFOA (perfluorooctanoic acid) and PFOS (perfluorooctane sulfonate) are synthetic chemicals that can be found in:
These chemicals remain in the environment and in our bodies for a long time. A new study found that women exposed to these chemicals increase their risk of developing osteoarthritis. It is important to note that more work needs to be done to say for sure whether these chemicals do indeed increase the risk of osteoarthritis in women. Researchers believe that women’s increased risk is somehow hormone related.
Although on a personal level it is hard to avoid exposure to these chemicals due to their prevalence in so many industries, there are measures in place to reduce the use of these chemicals on a global level.
In Canada, an agreement was created between Environment Canada, Health Canada, and four companies from the perfluorinated products industry to reduce PFOA and PFOS content in products by 95 percent by the end of 2010. The groups have also voluntarily committed to eliminating the remaining 5 percent by the end of 2015.
“The good thing is that it’s [PFOA] coming out of the environment so we are already having less exposure,” says Klinkhoff.
Supplements for osteoarthritis
Here are some of the supplements that may benefit those with osteoarthritis. As always, check with your health care practitioner to make sure a supplement is right for you.
