Gallstones

Gallstones are solid crystals that can form in the gallbladder, a small organ beneath the liver that stores bile produced by the liver. These stones can be very small, like a grain of sand, or as large as golf balls. There are two main types of gallstones: cholesterol and pigment stones. Cholesterol stones are the most common and are caused by an excess of cholesterol in the bile. Pigment stones are caused by an excess of bilirubin, a chemical produced during the breakdown of red blood cells.

Nutrition plays a key role in the prevention and treatment of gallstones. A diet high in fats and cholesterol can increase the risk of developing cholesterol stones, while low fiber intake can also contribute to their development. Conversely, a diet rich in fiber, fruits, vegetables, and whole grains can help reduce the risk of gallstone formation. Adequate hydration is also important as it supports normal gallbladder function.

Hello,
how do gallstones form and how can their formation be prevented?
Thank you.

Gallstones form in situations where there is a significant imbalance in the components of bile (bile acid salts, phospholipids, cholesterol) - this gradually leads to the crystallization and precipitation of these components. Poor dietary habits (high fat content, fiber deficiency, etc.), liver metabolism disorders, overweight, stress, and side effects of certain medications are most often to blame.

Prevention in this regard is (theoretically) relatively simple, but in real life, it is far from easy - dietary adjustments alone may not solve the problem, as stress factors (which are generally difficult to eliminate), overweight, and certain diseases (such as diabetes) have a significant impact.

Nutrition educator, lecturer, and author of the educational system and the ZOF learning application.

Mgr. Martin Jelínek has been systematically involved in nutrition education since 1999. He is the founder of ATAC, the educational company behind NutriCourses, and the author of an educational system focused on nutrition, healthy lifestyle, and the practical application of nutrition knowledge.

He graduated from the Faculty of Science at Masaryk University in Brno. Throughout his professional career, he has combined nutrition, education, and the practical application of acquired knowledge. His educational system also includes the ZOF (Zone of Optimal Functioning) learning application, where students turn theory into practical work with meal plans.

In 2007, he launched the first intake of a six-month course focused on the education of nutrition advisors. Over time, this course became the foundation for the further development of the educational system and a range of specialised courses.
