Which condition commonly presents in individuals aged 40 years or older and occurs more often in women?

• A. Gout
• B. Osteoid osteoma
• C. Gallstones
• D. Ankylosing spondylitis

Answer: (C)

The key idea is that some conditions have a demographic pattern, with certain ages and sex more commonly affected. Gallstones fit this pattern: they are especially common in people around 40 years and older and occur more often in women. Estrogen increases cholesterol saturation in bile and can slow gallbladder emptying, both of which promote stone formation. The familiar “four Fs”—female, fat, forty, fertile—summarizes this risk profile. In many patients, gallstones cause episodic right upper quadrant or epigastric pain, sometimes after fatty meals, though some remain asymptomatic. By contrast, gout tends to present in men (though risk rises with age and hormones do change post-menopause), osteoid osteoma occurs in younger individuals, and ankylosing spondylitis typically starts in adolescence or early adulthood with a male predominance.
