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.
Dysmenorrhea
Dysmenorrhea is painful menstruation, commonly causing cramping in the lower abdomen around the beginning of a menstrual period. Pain may also involve the lower back or thighs and may be accompanied by nausea, diarrhea, headache, dizziness, or fatigue. Primary dysmenorrhea occurs without another pelvic disease, while secondary dysmenorrhea results from an underlying condition and may develop later or become progressively worse.

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.
Dysmenorrhea
Diagnosis is based on a detailed menstrual history and the pattern, timing, severity, and duration of pain. A pelvic examination may be performed when secondary causes are suspected. Ultrasound or other investigations may be recommended when pain is severe, begins later than expected, persists despite usual treatment, becomes progressively worse, or is accompanied by abnormal bleeding or other symptoms suggesting an underlying pelvic condition.

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.
Dysmenorrhea
Some cases of dysmenorrhea cannot be prevented because primary menstrual pain is related to normal biological processes and individual sensitivity. Regular physical activity, adequate sleep, balanced nutrition, stress management, and avoiding smoking may support overall health. Persistent, severe, or progressively worsening menstrual pain should be evaluated because identifying and treating an underlying pelvic condition can reduce recurrent symptoms.

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.
Dysmenorrhea
Risk factors for dysmenorrhea include younger age at menstruation, younger age at first menstrual periods, a family history of painful periods, heavy or prolonged menstrual bleeding, and smoking. Secondary dysmenorrhea is more likely when an underlying gynecological condition is present. Symptoms may also be influenced by the timing and progression of the underlying condition.
