Overview

Diarrhea
Diarrhea means passing loose or watery stools more often than is normal for a person. It can be sudden and short-lived or continue for several weeks. Common symptoms include frequent bowel movements, abdominal cramps, urgency, nausea, and sometimes fever or blood in the stool. The main concern with significant diarrhea is loss of water and electrolytes, which can lead to dehydration.
Pericarditis
Pericarditis is inflammation of the pericardium, the thin sac surrounding the heart. It can cause sharp chest pain that may become worse with deep breathing or lying down and improve when sitting forward. Viral infections are a common cause, but other infections, autoimmune diseases, medications, injury, and medical procedures can also contribute. Some cases resolve on their own, while others require treatment. Complications such as fluid accumulation around the heart can occur and may interfere with normal heart function.

Diagnosis

Diarrhea
Short-term diarrhea is often diagnosed from symptoms, medical history, and a physical examination. Healthcare professionals assess duration, frequency, recent food or travel exposures, medicines, and signs of dehydration. Stool tests may be needed when diarrhea is severe, persistent, bloody, associated with fever, or suspected to be caused by an infection. Blood tests or other investigations may be used when an underlying digestive disorder is suspected.
Pericarditis
Pericarditis is diagnosed using the history, characteristic chest pain, physical examination, electrocardiogram, blood tests, and cardiac imaging. An electrocardiogram may show changes associated with inflammation, while blood tests can identify markers of inflammation or heart injury. Echocardiography can detect fluid around the heart and assess its effect on cardiac function. Chest imaging and additional tests may help identify an underlying infection, autoimmune condition, or other cause.

Prevention

Diarrhea
Many infectious causes of diarrhea can be reduced through careful handwashing, safe preparation and storage of food, drinking treated or safe water, and avoiding contaminated food. Travelers should follow local food and water safety precautions. Appropriate vaccination can prevent some infections that cause diarrhea. Using antibiotics only when prescribed can also reduce certain medication-related complications. People with ongoing diarrhea should seek medical care when symptoms are severe or dehydration develops.
Pericarditis
Some causes of pericarditis cannot be prevented, but managing underlying inflammatory or systemic conditions and following medical advice after infections or heart procedures may reduce risk in certain situations. People with a previous episode should follow recommendations intended to reduce recurrence. New or unexplained chest pain should be assessed promptly because pericarditis can resemble other serious heart and lung conditions. Preventive measures depend largely on the underlying cause.

Risk Factors

Diarrhea
Risk factors include eating contaminated food, drinking unsafe water, traveling to areas where sanitation is limited, poor hand hygiene, and contact with someone who has an infectious illness. Antibiotic use can disturb normal intestinal bacteria and cause diarrhea. Certain digestive disorders, food intolerances, weakened immune function, and some medicines can also increase the likelihood of recurrent or persistent diarrhea.
Pericarditis
Risk factors for pericarditis include recent viral or other infections, autoimmune diseases, kidney failure, cancer, previous heart surgery, chest injury, radiation exposure, and certain medicines. A previous episode of pericarditis increases the chance of recurrence. People with systemic inflammatory diseases may be particularly susceptible. In many cases, however, no specific risk factor or cause is identified.
