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.
Ectopic Pregnancy
An ectopic pregnancy occurs when a fertilized egg implants outside the main cavity of the uterus, most often in a fallopian tube. Because these tissues cannot support a normally developing pregnancy, an ectopic pregnancy can cause serious internal bleeding if the pregnancy continues to grow and the affected structure ruptures. Symptoms may include a missed menstrual period, pelvic or abdominal pain, vaginal bleeding, dizziness, or shoulder pain. Some ectopic pregnancies are detected before severe symptoms develop, making early evaluation important when pregnancy occurs with unusual pain or bleeding.

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.
Ectopic Pregnancy
Diagnosis of ectopic pregnancy usually involves a pregnancy test together with clinical assessment, blood testing for the pregnancy hormone hCG, and transvaginal ultrasound. The pattern of hCG levels over time can provide useful information but does not by itself establish the location of a pregnancy. Ultrasound may identify a pregnancy inside the uterus or findings suggesting an ectopic pregnancy. When the diagnosis remains uncertain, repeat testing and imaging may be required. Severe pain, fainting, or signs of internal bleeding require urgent medical assessment.

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.
Ectopic Pregnancy
There is no guaranteed way to prevent every ectopic pregnancy, but reducing the risk of pelvic infections, avoiding tobacco, and seeking appropriate care for sexually transmitted infections can help reduce some contributing factors. People with a previous ectopic pregnancy or conditions affecting the fallopian tubes may benefit from early medical evaluation when pregnancy occurs. Early confirmation of pregnancy location is particularly important when risk factors are present or when pain or bleeding develops. Any pregnancy accompanied by severe abdominal pain, fainting, or significant bleeding requires urgent assessment.

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.
Ectopic Pregnancy
Risk factors for ectopic pregnancy include a previous ectopic pregnancy, previous pelvic inflammatory disease, damage or surgery involving the fallopian tubes, certain fertility treatments, and some conditions affecting the reproductive tract. Pregnancy occurring with an intrauterine device in place is uncommon, but if pregnancy does occur, the relative likelihood of it being ectopic is higher. Smoking and increasing maternal age have also been associated with increased risk. An ectopic pregnancy can still occur without any recognized risk factor.
