Overview

Ankylosing Spondylitis
Ankylosing spondylitis is a chronic inflammatory condition that mainly affects the spine and the joints connecting the spine and pelvis. It commonly causes lower back or hip pain and stiffness that may worsen after periods of rest and improve with movement. In some people, inflammation can also affect other joints, the eyes, skin, or digestive system.
Endometriosis
Endometriosis is a condition in which tissue similar to the lining of the uterus grows outside the uterus. It commonly affects the pelvic area and may cause painful periods, pelvic pain, pain during sexual activity, or difficulty becoming pregnant. Symptoms can vary widely, and some people may have endometriosis without obvious symptoms.

Diagnosis

Ankylosing Spondylitis
Diagnosis of ankylosing spondylitis is based on symptoms, physical examination, medical history, and imaging. X-rays may show changes in the sacroiliac joints or spine, while MRI can detect inflammation earlier in the disease. Blood tests may include markers such as C-reactive protein and testing for HLA-B27. No single test confirms the condition in every person.
Endometriosis
Diagnosis of endometriosis is based on symptoms, medical history, and pelvic examination, together with imaging when appropriate. Ultrasound or MRI may identify some areas of endometriosis or related ovarian cysts, but normal imaging does not always exclude the condition. In selected cases, laparoscopy may be used to directly examine the pelvis and obtain tissue for confirmation.

Prevention

Ankylosing Spondylitis
Ankylosing spondylitis cannot currently be prevented because its exact cause is unknown and genetic factors play an important role. People with a strong family history or persistent inflammatory back symptoms should seek medical evaluation. Early diagnosis and appropriate management, including regular physical activity and exercises recommended by healthcare professionals, can help maintain mobility and posture.
Endometriosis
Endometriosis cannot always be prevented because its exact cause is not fully understood. Early evaluation of persistent pelvic pain, painful periods, or other concerning symptoms can help identify the condition and reduce delays in care. People with symptoms or a family history should discuss appropriate evaluation with a healthcare professional rather than relying on preventive measures alone.

Risk Factors

Ankylosing Spondylitis
Risk factors include a family history of ankylosing spondylitis and genetic susceptibility, particularly the HLA-B27 gene. Symptoms commonly begin before age 45. People with inflammatory bowel diseases such as Crohn disease or ulcerative colitis, or with psoriasis, may also have increased risk of developing ankylosing spondylitis.
Endometriosis
Risk factors for endometriosis include having a family history of the condition and certain reproductive or menstrual characteristics that result in greater lifetime exposure to menstrual cycles. Symptoms may begin during the reproductive years. Having a close relative with endometriosis can increase susceptibility, although many people who develop the condition have no known family history.
