Gallstones: Causes, Symptoms, and Treatment
Gallstones — also known as cholelithiasis — affect approximately 20% of the world's population. They form in the gallbladder, a small organ located near the liver that stores bile for fat digestion. Stones can range in size from 1 mm to as large as 15 cm. This article examines how gallstones develop, the symptoms they produce, and the treatment options available.
Fatal Familial Insomnia (FFI) — Prion Disease
Fatal Familial Insomnia is a rare inherited prion disease that affects the central nervous system. It belongs to a family of neurodegenerative disorders caused by misfolded proteins. The condition progressively impairs sleep, cognition, and motor function, and is ultimately fatal.

Gallstones form when bile in the gallbladder becomes concentrated and hardens into solid deposits, a condition that affects a significant portion of the global population. These stones can vary widely in size, from tiny grains to larger formations that may block bile ducts and cause sharp abdominal pain, nausea, and digestive discomfort. Risk factors include dietary habits, rapid weight loss, and certain metabolic conditions. Treatment approaches range from watchful waiting for asymptomatic cases to surgical removal of the gallbladder for recurrent or severe symptoms. Understanding the formation process and recognizing early warning signs can help individuals seek timely medical advice and manage their digestive health more effectively.
