Obesity can increase pressure on the joints, which may increase wear and tear. This, in turn, may raise the risk of osteoarthritis (OA) or hasten its progress.
According to a 2022 review article, obesity is the most important risk factor for OA. As obesity increases the load the joints bear, it may cause OA in people who otherwise would not have developed it. Age is another important risk factor.
Read on to learn more about osteoarthritis and obesity.
Yes, OA and obesity have links. Obesity can raise the risk of OA, and having OA can make it more difficult to treat obesity, depending on the joints it affects.
Obesity can also create an inflammatory state that raises the risk of inflammatory conditions, such as arthritis.
Additionally, obesity can impact the severity and progression of OA symptoms. In a

- 16% of people with an underweight or moderate BMI
Obesity has the most significant effect on weight-bearing joints, such as the knees and the hips. Over time, these joints can wear down. Excess weight accelerates the process.
Obesity also causes chronic inflammation. This can affect any joint, including those that do not bear significant weight. For example, hand arthritis is about twice as common in people with obesity, according to the Arthritis Foundation.
Having a moderate weight can help with OA. According to a
In addition, weight loss may help reduce systemic inflammation. Fat tissues

Having OA can make some approaches to weight loss more challenging. For example, pain and difficulty moving certain joints may make exercising or cooking homemade meals difficult. However, some strategies can help.
Diet is one of the most important components of obesity treatment. Even if certain factors affect a person’s ability to exercise, they may still be able to alter their diet to induce gradual, sustainable weight loss, if needed.
Experts typically recommend people do this by eating a calorie-controlled diet, consuming fewer calories than they need daily. This may involve reducing the intake of carbohydrates, fats, or both. A dietitian can help a person understand which approach is best for them.
As a general guide, the
- focusing on fruits, vegetables, whole grains, and lean proteins
replacinghigh calorie drinks with water, sparkling water, or unsweetened tea or coffee
- avoiding foods with added sugars
- avoiding foods high in saturated fat
Exercise may be more difficult with OA. However, it is also
It may help to try types of exercise that put less pressure on the joints, such as:
- water aerobics
- tai chi
- using an elliptical machine
If possible, people who experience pain from exercise may wish to consult a physical therapist for a personalized plan. Alternatively, a doctor may be able to make a referral to a physical therapist.
In cases where a person with a high BMI has tried lifestyle and dietary interventions that have not helped with weight management, a doctor may suggest medical treatments to aid with weight loss.
Weight loss medications may help some people. Certain medications may also help with metabolic syndrome and systemic inflammation, potentially reducing some of the effects of obesity, including OA.
Losing weight can be challenging, especially for people managing multiple conditions. A person may seek support and advice from a doctor or other healthcare professional specializing in weight management if needed.
Additionally, a rheumatologist may be able to help improve a person’s OA treatments to make weight loss easier. A dietitian can provide guidance on food, meal size, and overcoming any potential obstacles in making dietary changes.
There are also a range of support groups for people with arthritis and obesity. The following resources may be beneficial:

- The Arthritis Foundation’s resource finder
- The CreakyJoints list of arthritis support groups and resources
- Overeaters Anonymous, an organization for people experiencing difficulty managing eating habits

Obesity and osteoarthritis (OA) often occur together. Obesity is one of the most important risk factors for OA and can raise the chances of developing it in joints that bear weight and other joints around the body, such as the hands.
Sometimes, joint pain may lead to difficulty exercising, which can make adding this to a person’s treatment plan more challenging. However, there are ways of managing this that may help.
Doctors, physical therapists, and dietitians can offer guidance on diet and exercise strategies. In some cases, medications or other treatments may also be an option.
