Yes it affected my shoulders at different times. I've had frozen shoulder twice and the first time it took 2 years and physio to recover, the second time, it took close to 6 months. Couldn't raise my arms and couldn't reach to undo my bra. Very painful. Also you do suffer irritable bowel with AS. My whole life I've had problems. My knees bother me when the weather is way too damp.

Can ankylosing spondylitis affect the shoulders, knees, and bowels?

Yes, AS can definitely affect all three of these areas, though symptoms vary from person to person.

Shoulders and Knees:

AS commonly causes pain and inflammation beyond the spine. The shoulders are frequently affected, and while shoulder pain is usually described as mild, it can interfere with quality of life. You might experience this pain months or even years after diagnosis, depending on disease activity.

The knees can also be affected as AS impacts peripheral joints (those farther from the center of the body). Pain in these areas may result from direct inflammation or from enthesitis, which is inflammation where tendons or ligaments attach to bone.

Bowels:

Gastrointestinal problems are common with AS. The inflammation can cause symptoms like:
* Bloating
* Diarrhea or constipation
* Abdominal pain
* Flatulence

Research shows that as many as 60 percent of people with AS have microscopic gut inflammation without even experiencing GI symptoms. Between 6 to 14 percent of people with AS also develop inflammatory bowel disease (IBD), including Crohn's disease or ulcerative colitis.

Some MySpondylitisTeam members notice their joint pain worsens during bowel flares, showing how these symptoms can be connected.

If you're experiencing any of these symptoms alongside your AS, it's worth discussing with your doctor so they can help manage all aspects of your condition.

It can affect your entire body. Inflammatory molecules are carried by your blood through the entire body. It is unfortunate that the conventional medicine community places distinct terminology on autoimmune conditions instead of just labeling the disease as "autoimmune disease" because it leads to much confusion as well as adding a lot of worry to patients as they receive multiple autoimmune diagnoses over time. What is more important, indeed MOST important, is to identify what is causing the body to overproduce the inflammatory chemicals that are attacking. Address the causes, cure the disease. Lastly, keep in mind that even when the disease process is stopped, damage done by the disease needs to be addressed. Best of luck. Reach out anytime for suggestions how to do this long process of healing. Yours in better health P 😌🙏
