Overview

Irritable Bowel Syndrome
Irritable bowel syndrome is a common disorder affecting the digestive system and causing recurrent abdominal pain associated with changes in bowel habits. Some people mainly have constipation, others mainly have diarrhea, and some alternate between both. Symptoms may also include bloating, gas, urgency, or a feeling of incomplete bowel movements. IBS does not cause the structural damage seen in inflammatory bowel diseases.
Polycythemia Vera
Polycythemia vera is a chronic blood disorder in which the bone marrow produces too many red blood cells. The increased number of blood cells can make the blood thicker and increase the risk of blood clots. Some people also have increased white blood cells or platelets. Symptoms may include headache, dizziness, itching after a warm bath, fatigue, or a feeling of fullness in the abdomen.

Diagnosis

Irritable Bowel Syndrome
Diagnosis is usually based on the pattern of abdominal pain and changes in bowel habits together with a medical history and physical examination. Healthcare professionals may use established symptom criteria and perform selected blood or stool tests to exclude other conditions. Additional testing, such as colonoscopy, may be recommended when warning signs, unusual symptoms, older age at onset, or other clinical concerns suggest another diagnosis.
Polycythemia Vera
Diagnosis involves a complete blood count showing an increased red blood cell level and may also show increased white blood cells or platelets. Healthcare professionals may measure erythropoietin levels and test blood cells for JAK2 mutations. Additional evaluation may include examination of the bone marrow and assessment for other causes of an elevated red blood cell count. The diagnosis is based on laboratory findings together with the clinical and medical history.

Prevention

Irritable Bowel Syndrome
There is no guaranteed way to prevent irritable bowel syndrome, but some people can reduce symptom flare-ups by identifying and managing individual triggers. Regular meals, adequate fluid intake, physical activity, sufficient sleep, and stress-management strategies may help. Dietary changes should be individualized because triggers differ. People with persistent or changing bowel symptoms should seek medical evaluation rather than assuming that symptoms are caused by IBS.
Polycythemia Vera
There is no established way to prevent polycythemia vera because it usually results from acquired genetic changes that cannot be predicted or avoided. Early evaluation of persistent abnormal blood counts can help identify the disorder and reduce complications. People with the condition should follow medical treatment and recommendations aimed at reducing blood clot risk, avoid tobacco exposure, and seek urgent care for symptoms that may indicate a serious clotting complication.

Risk Factors

Irritable Bowel Syndrome
Risk may be increased by a history of gastrointestinal infection, changes in the gut microbiome, food-related triggers, and psychological stress. IBS is more common in women and often begins in younger adulthood. A family history may increase susceptibility. People with other functional gastrointestinal disorders or certain psychological stressors may also experience a greater burden of symptoms, although these factors do not necessarily cause IBS in every individual.
Polycythemia Vera
The risk of polycythemia vera increases with age and is uncommon in children and young adults. It occurs somewhat more often in men than women. Having certain blood disorders or related genetic changes may be associated with increased risk. Unlike secondary polycythemia, lifestyle factors such as smoking or living at high altitude are not the direct cause of polycythemia vera, although they can increase red blood cell counts for other reasons.
