Weight and joint pain: how body weight affects your joints and what actually helps

How body weight affects your joints

Joint pain is complex. People of all sizes can experience joint discomfort, and not all people with a higher body weight have joint pain. Though, research suggests that gaining about 11 pounds is associated with a 36% higher risk of developing osteoarthritis, which, for some people, can lead to discomfort in the joints. Here are some potential explanations for how body weight may affect your joints:

• Changes in joint loading. Your knees, hips, and other joints experience forces as you walk, climb stairs, and move throughout the day. Higher body weight can increase some of these forces, but that doesn’t mean your joints are being damaged. “Higher body weight means more load on these structures with each movement, especially if they’re not prepared for that specific load,” says Nick Mercer, PT, DPT, a Hinge Health physical therapist. “But your joints are designed to adapt, especially as you increase your muscle strength and mass.”

• Inflammation. Adipose (fat) tissue plays an active role in your body’s metabolism and produces inflammatory proteins that may contribute to joint pain. “Adipose tissue is metabolically active, so the more we have, the more inflammatory proteins there are to make everything, joints included, feel more sensitive,” says Dr. Mercer. Some researchers believe this may help explain some of the relationship between higher body weight and joint conditions such as osteoarthritis, including in joints that don’t regularly bear body weight (such as your hands). 

• Changes in how you move. Because higher body weight can increase the forces placed on your joints, you may experience discomfort that prevents you from moving as frequently or adjusting how you perform certain activities. Prolonged inactivity may contribute to stiffness and reduced strength. Finding ways to keep moving can help you maintain your confidence and physical function.

• Chronic conditions linked to higher body weight. Conditions such as diabetes and metabolic syndrome can occur alongside higher body weight, which may also affect your joint health. But weight alone doesn’t determine whether someone will develop joint pain.

Which joints are most affected

Some joints may be more sensitive to changes in body weight than others. While your knees and hips often get the most attention, your back, ankles, feet, and even hands can be affected, too.

• Knees. Your knees handle considerable force during everyday activities. Research suggests that the force on your knees during walking can be several times your body weight. Another study found that among older adults with knee osteoarthritis, each pound of weight lost was associated with about four pounds less force on the knee per step. Still, knee pain isn’t simply about body weight. Muscle strength, activity levels, and other health factors matter, too.

• Hips. Your hips support your body weight during everyday activities like walking, standing, and climbing stairs. Research shows that different movements place different demands on your hip joints. Strengthening the muscles around your hips can help support these joints and make everyday activities feel easier and more comfortable—no matter your body weight.

• Lower back. Body weight is one of several factors associated with back pain, but the relationship isn’t straightforward. Staying active and building strength can help, even without weight loss. “We typically see a reduction in back pain when someone reaches a healthier weight, but we can also see improvement as someone builds strength, even without weight loss,” says Dr. Mercer.

• Ankles and feet. These joints play an important role in supporting the body and facilitating movement, whether walking, standing, or transferring between positions. Discomfort or soreness can develop with prolonged activity or increased demands on these joints. Gradually building strength in the supporting muscles and adapting activity to your current abilities can help support comfort and mobility.

• Hands and fingers. The relationship between body weight and inflammation may help explain why weight-related joint conditions aren’t limited to the lower body. But hand pain can have many causes, including arthritis and repetitive activities, such as gardening or packing boxes, for example.

How movement helps with weight and joint pain

Regular exercise is one of the most effective ways to manage many types of joint pain, and its benefits can be reaped well before meaningful weight loss begins.

“Targeted movement strengthens the muscles that support and cushion joints, reduces inflammation, improves range of motion, and helps the body manage load more efficiently,” says Dr. Mercer.

Regular movement can help improve strength, mobility, and confidence in your body’s ability to handle everyday activities. Some people notice that walking, climbing stairs, or getting up from a chair becomes easier as they become more active, even when their weight stays the same.

The key is finding a comfortable starting point. Walking, cycling, swimming, and strength training are all options, but there’s no single type of exercise that’s best for everyone. You can modify movements, take breaks, and gradually increase the challenge as your body adapts.

Treatments for weight-related joint pain

Managing joint pain often involves a combination of movement, pain medication relief, and healthy habits that support your overall health. The best approach depends on your symptoms, health history, and personal goals, not just your body weight. These approaches include:

• Try physical therapy and targeted exercises. Targeted exercises, such as the ones above, help strengthen the muscles that support your joints, which, in part, eases pressure off tender areas. You can do exercise therapy at home or work with a physical therapist who can guide you through movements tailored to your needs. You can see a physical therapist in person or use a program like Hinge Health, where you may access a PT via telehealth/video visit.

• Stay active. Walking, swimming, cycling, dancing, and even household chores can help you stay mobile. If a certain activity increases discomfort, try adjusting the pace, duration, or intensity rather than giving it up entirely. “The most important thing for staying active is something you enjoy, because you’ll be more likely to keep doing it,” says Dr. Mercer.

• Consider over-the-counter (OTC) medication. Pain relievers such as ibuprofen (Advil, Motrin), naproxen (Aleve), and acetaminophen (Tylenol) can help ease pain so you can do your targeted exercises and stay active when you have joint pain. Other options are topical NSAIDs or pain relief creams. If you have a medical condition or take other medications, check in with your provider to make sure these OTC options are ‌safe to take.

• Prioritize nutrition. Eating a balanced, nutrient-rich diet supports your body's natural healing processes while helping you maintain a weight that’s healthy for your body. Focus on foods like fruits, vegetables, fatty fish, nuts, seeds, and whole grains. These foods help reduce inflammation and offer nutrients that support tissue repair, such as omega-3 fatty acids and vitamins C and D. For individualized guidance, consider working with a registered dietitian.

• Consider lifestyle modifications. Factors like sleep, stress, nutrition, and certain activities can all play a role in how you feel. In fact, many people are surprised to learn that pain isn't just about what's happening physically — your daily habits and overall well-being can have a real impact, too. “Staying curious about how your routines affect your muscles and joints can help you identify where small changes might help reduce pain,” says Dr. Mercer. 

• Try complementary treatments. Talk to your provider if you're interested in trying alternative treatments for joint pain relief, such as massage, acupuncture, or chiropractic care.

• Ask about TENS therapy. TENS, or transcutaneous electrical nerve stimulation, uses gentle pulses to quiet your pain response and help reduce joint pain. One option is the wearable device Enso, available through Hinge Health. It’s small, wireless, and portable.

Does losing weight help joint pain? 

For some people, weight loss can help reduce joint pain, particularly in weight-bearing joints like the knees. Research suggests that weight loss may improve pain and function in some people with knee osteoarthritis. But, again, the relationship between weight and pain is complex, and losing weight doesn’t guarantee that joint pain will disappear.

Just as importantly, weight loss isn’t a prerequisite for feeling more comfortable. Regular movement and strength training can improve joint function, physical capacity, and overall well-being even when your weight doesn’t change.

“Without strength, our muscles can’t support our joints, and we can’t easily do a lot of the things that would contribute to weight loss efforts, like cardio,” says Dr. Mercer.

If weight management is one of your health goals, your healthcare provider or a registered dietitian can help you find an approach that supports your overall health without overly restrictive habits. But regardless of your goals, building strength and staying active are worthwhile steps on their own.

Tips to manage joint pain and body weight 

Managing joint pain when body weight is a factor comes down to a handful of consistent habits, including choosing movement that works for your joints right now, to supporting your body’s recovery with sleep, nutrition, and stress management. Consider these tips from Hinge Health physical therapists:

• Start with low-impact movement. Walking, swimming, cycling, and water aerobics are all effective and gentle on joints, compared to high-impact exercise. Building a consistent low-impact habit is more valuable than occasional intense workouts, so Dr. Mercer recommends trying to find activities you enjoy doing frequently.

• Build strength gradually. Strong muscles reduce the load that joints have to absorb. Even modest strength gains in the quadriceps (front of thigh muscles), glutes, and core can noticeably improve knee and hip pain, Dr. Mercer says.

• Take movement snacks throughout the day. If you’ve been sitting or standing for a while, a short walk or a few gentle stretches may help ease stiffness. “Even five minutes of walking or gentle stretching every hour can reduce stiffness and improve circulation,” says Dr. Mercer.

• Improve your sleep quality. Joint pain can make it harder to sleep, while poor sleep can increase pain sensitivity, creating a frustrating pain-sleep cycle. Practicing good sleep hygiene, such as keeping a consistent bedtime, limiting screen time before bed, and creating a cool, dark sleep environment, can help you get more restorative rest and better manage discomfort.

• Work with a provider on weight goals, if relevant. Seek support for weight-related goals, if you have them. A healthcare provider or registered dietitian can help you develop a sustainable plan that takes your health needs and preferences into account.

When to see a doctor

Joint pain is common, and many people find relief through movement, exercise, and other self-care strategies. But it’s worth checking in with a healthcare provider if pain is persistent, worsening, or making everyday activities difficult. Seek medical care if you experience:

• Sudden or severe joint pain, particularly with significant swelling, redness, or warmth

• Pain that isn’t improving or continues to interfere with your daily routine

• Difficulty walking, bearing weight, or using an affected joint

• New or worsening symptoms alongside a condition such as diabetes or gout

Seek urgent medical evaluation if you have a hot, swollen joint accompanied by fever or feel generally unwell, as this can sometimes indicate a joint infection.

PT tip: Build strength for everyday movements 

“Building muscle strength is important, but so is practicing the movements you use every day,” Dr. Mercer says. For example, strengthening your quads with leg extensions can help support your knees, but exercises like step-ups and lunges can also help you build the strength, balance, and coordination needed to climb stairs more comfortably. 

Think about which activities you’d like to make easier, whether that's getting out of a chair, carrying groceries, or taking the stairs, and work with your PT to find exercises that help you build strength for those specific movements.
