People with AS may also have other related health conditions. These can include:

  • acute anterior uveitis (or simply iritis) - a chronic eye inflammation that can cause blurred vision, eye pain and redness, and sensitivity to light
  • psoriasis - a non-contagious inflammatory skin condition that causes a red patchy, scaly skin rash covered in silvery scales that can be painful or itchy
  • inflammatory bowel disease - two medical conditions that affect the digestive system, Crohn's disease and ulcerative colitis, causing bowel inflammation, sores, bleeding, and, in the case of Crohn's disease, scarring of the digestive system. Symptoms include abdominal pain, cramps, diarrhea, fatigue, blood in the stool, and fever.
  • heart problems - people with AS may also be at increased risk for heart problems

Having AS does not necessarily mean that you will also develop these conditions, nor does having one of these conditions mean AS is also present. Talk to your doctor if you have any concerns.
