Ozempic Knee Pain - Causes & How to Manage Joint Discomfort from Semaglutide

What is Ozempic?

Ozempic (semaglutide) is an injectable prescription medication used to improve blood sugar control in adults with type 2 diabetes. It belongs to a class of medications called glucagon-like peptide-1 (GLP-1) receptor agonists.

Ozempic works by mimicking the effects of GLP-1, an incretin hormone that is produced naturally in the body. Incretin hormones help regulate blood sugar levels by stimulating the release of insulin when blood sugar is high, slowing digestion, and suppressing appetite.

By acting like GLP-1, Ozempic encourages the pancreas to produce more insulin when blood sugar levels rise after eating. It also reduces appetite and slows digestion to decrease the spike in blood sugar after meals.

Ozempic is a once-weekly injection prescribed along with diet and exercise to improve glycemic control in adults with type 2 diabetes. It can be used by itself or in combination with other diabetes medications.

Ozempic and Knee Pain

While Ozempic can help manage type 2 diabetes, some people using this medication have experienced joint pain, including knee pain, as a side effect.

In clinical trials of Ozempic for diabetes, between 2-6% of patients reported joint pain or arthritis. Knee pain, specifically, was reported by 1-2% of Ozempic users in studies.

The reasons why Ozempic may cause joint or knee pain are not entirely clear. However, there are some possible explanations:

Weight Loss

One of the main effects of Ozempic is decreasing appetite and promoting weight loss. Losing a significant amount of weight quickly can sometimes lead to increased joint pain.

As weight is lost, pressure on the joints - especially weight-bearing joints like the knees and hips - is reduced. This change in forces on the joint along with ligament laxity that often occurs with weight loss could result in discomfort or pain in some individuals.

Inflammation

Some research indicates that GLP-1 receptor agonists like Ozempic may have anti-inflammatory effects. However, other studies have found they may temporarily increase levels of certain inflammatory markers.

It's theorized that Ozempic may initially cause a slight bump in inflammation, which could temporarily aggravate joint pain in susceptible individuals. In the long-run, Ozempic's anti-inflammatory properties are expected to prevail.

Joint Fluid Changes

Ozempic promotes fluid loss from the body through increased urination. This diuretic effect could potentially lead to decreased joint lubrication, which may worsen pain in joints like the knees.

Blood Sugar Fluctuations

Some people taking Ozempic experience hypoglycemia (low blood sugar). Blood sugar fluctuations have been associated with worsening of joint pain symptoms in those with arthritis.

If Ozempic leads to large dips and spikes in blood glucose, it may exacerbate knee discomfort - especially in those with underlying osteoarthritis.

Does Ozempic Cause Knee Osteoarthritis?

There is no evidence at this time that Ozempic can directly cause or accelerate osteoarthritis - the most common form of chronic knee pain and joint damage. Osteoarthritis results from years of wear-and-tear on the joint or direct injury.

However, by potentially contributing to intermittent knee pain flares, Ozempic could aggravate existing osteoarthritis or make the condition more symptomatic in some patients.

Obesity and Knee OA

Being obese or overweight significantly raises the risk of developing knee osteoarthritis. This is because excess weight places abnormally high amounts of mechanical stress on the knee joint.

By promoting weight loss, Ozempic could actually lower risk for obese patients of getting knee osteoarthritis in the first place. However, rapid weight loss could make osteoarthritis temporarily more painful in the short-term.

Inflammation and Knee OA

Chronic inflammation is believed to play a key role in the progression of osteoarthritis. Factors that reduce inflammation may slow the disease.

Some research shows that GLP-1 drugs like Ozempic have anti-inflammatory properties that could potentially benefit osteoarthritis if sustained over time. But any temporary bumps in inflammation could also aggravate osteoarthritis knee pain.

Managing Ozempic-Related Knee Discomfort

For most people taking Ozempic, knee pain is mild and temporary, often improving within the first few months of treatment. However, if you experience persistent or worsening joint pain, speak to your doctor.

To help manage knee discomfort related to Ozempic, the following methods may help:

Losing Weight Gradually

Losing weight at a slow, steady pace instead of rapidly can help reduce impact on the knees. A loss of about 1 pound per week is a sustainable goal.

Low-Impact Exercise

Low-impact activities like swimming, cycling and strength training can improve knee pain without stressing joints. But check with your doctor before significantly increasing exercise.

Proper Footwear

Cushioned shoes with good arch support can reduce knee loading and irritation. Replace worn-out athletic shoes regularly.

Pain Medications

Over-the-counter pain relievers like acetaminophen or NSAIDs can temporarily alleviate osteoarthritis knee discomfort. Use the lowest effective dose.

Braces and Supports

Braces, sleeves, and taping can help stabilize the joint and improve pain. Consult a physiotherapist for guidance on proper fitting and use.

Dietary Changes

A Mediterranean-style anti-inflammatory diet high in omega-3s and low in saturated fats may ease osteoarthritis inflammation.

Topical Treatments

Creams containing capsaicin, menthol, or NSAIDs could provide additional relief when applied to the knee.

Physical Therapy

Working with a physical therapist can build strength and improve joint biomechanics to take pressure off the knees.

When to See Your Doctor

You should speak to your healthcare provider if Ozempic-related knee pain:

• Does not improve within the first 2-3 months of starting Ozempic
• Progresses in intensity or frequency
• Is accompanied by swelling, clicking, or locking of the knee joint
• Leads to difficulty with daily activities like walking, climbing stairs, etc.
• Occurs along with other unexplained muscle aches or joint pains

Worsening knee pain with Ozempic could indicate an underlying issue like osteoarthritis, rheumatoid arthritis, gout or injury that may require additional treatment. It's also important to rule out rare side effects like severe joint pain.

The Bottom Line

Mild knee discomfort is not uncommon when starting Ozempic due to factors like weight fluctuations, inflammation changes, and fluid shifts in the body.

Rapid weight loss, blood sugar swings, and inflammation effects may also temporarily worsen osteoarthritis knee pain in some users.

However, overall Ozempic may benefit the knees in the long-run by promoting weight loss and through potential anti-inflammatory mechanisms.

Persistent or worsening knee pain should be evaluated by a doctor. But using conservative treatments, most people can manage temporary Ozempic-related knee discomfort.
