A pregnant patient with right upper quadrant pain after eating pizza is likely suffering from what condition?

The most likely condition affecting a pregnant patient experiencing right upper quadrant pain after eating pizza is cholecystitis. This condition often arises from the presence of gallstones that can obstruct the cystic duct, leading to inflammation of the gallbladder. Eating a fatty meal, such as pizza, can exacerbate symptoms since the gallbladder is stimulated to contract to aid in digestion, potentially causing pain if gallstones are present.

In pregnant individuals, the hormonal changes and increased pressure from the expanding uterus can make them more susceptible to gallbladder issues. This pain, especially after a high-fat meal, aligns with typical presentations of cholecystitis, characterized by epigastric or right upper quadrant pain, often accompanied by nausea or vomiting.

Appendicitis typically causes pain that begins around the belly button and then moves to the lower right quadrant, while placental abruption usually presents with abdominal pain, uterine tenderness, and possibly vaginal bleeding, unrelated to food intake.
