[72M] With sudden onset diarrhea and right lower quadrant abdominal pain

What might be happening

Based on the information you've provided, possible diagnoses include:

• Appendicitis: This is an inflammation of the appendix, a small organ attached to the large intestine. It typically presents with pain in the right lower quadrant of the abdomen, which can be sharp and severe. Diarrhea can also occur in some cases.

  • Treatment typically involves surgical removal of the appendix (appendectomy).

• Diverticulitis: This is an inflammation or infection of small pouches called diverticula that develop along the walls of the intestines. The signs and symptoms of diverticulitis include pain, which is usually in the lower left side of the abdomen, but it can occur on the right, especially in people of Asian descent, and in some cases, diarrhea.

  • Treatment includes antibiotics, pain relievers, and sometimes surgery.

• Gastroenteritis: This is an inflammation of the lining of the intestines caused by a virus, bacteria or parasites. Viral gastroenteritis is particularly common and highly infectious. Symptoms include diarrhea, abdominal pain, vomiting, headache, fever and chills.

  • Treatment typically involves self-care measures such as staying hydrated and rest.
