Biliary lithiasis, also called cholestasis, is one of the most frequent pathologies of the digestive system. It’s also defined as the presence of stones in the gallbladder or in the ducts, which can cause obstructive problems. Surprisingly, the size of gallstones can vary from the size of a grain of sand to the size of a golf ball!

Most cases of gallstones are asymptomatic, meaning that there aren’t any obvious symptoms to alert to the problem. And, in symptomatic cases, biliary colic is the main symptom, although an episode of acute cholecystitis may appear. Keep reading to learn more!

Acute cholecystitis

Acute cholecystitis is the main complication of gallstones. It’s characterized by inflammation of the gallbladder along with other discomforts such as abdominal pain, nausea, vomiting, and restlessness. There are two types of stones associated with this pathology:

  • Cholesterol lithiasis: it represents 75% of the cases of biliary lithiasis in the West. It forms because of alterations in the metabolism of bile acids and cholesterol.
  • Pigmentary lithiasis: it’s produced by anomalies in the metabolism of bilirubin (a pigment present in the bile). It accounts for 25% of the prevalence of bile lithiasis.

What can cause gallstones?

A person with abdominal pain.
The exact cause of gallstones is not entirely clear. However, there are several risk factors associated with its occurrence.

Although it isn’t yet clear why gallstones form, there are a number of factors that contribute to the formation of gallstones. It’s a pathology that occurs in both sexes, although it has greater prevalence in women.

In cholesterol lithiasis the main causes of stone formation are the result of:

  • Genetic predisposition of the individual
  • Alterations in lipid metabolism
  • Obesity or significant changes in weight
  • Alterations in the correct emptying of the gallbladder
  • Infections
  • Hepatic cirrhosis
  • Diet low in fiber and high in fat
  • Treatment with contraceptives or estrogen therapies

On the other hand, in pigmentary lithiasis the formation mechanism is complex. It occurs due to an increase in the bilirubin content in the bile. Moreover, this is shown in a study published in 2020.

General recommendations for biliary lithiasis

The general recommendation for people with gallstones should be as follows:

  • Eat a varied, balanced diet adapted to your individual needs
  • Maintain a healthy weight and avoid excess weight
  • Eat slowly and also chew correctly
  • Avoid fasting and copious meals, as both favor biliary lithiasis
  • Divide the diet into 5 daily meals
  • Do moderate exercise over 40 minutes a day, at least 3 times a week
  • Drink about 2 liters of water daily
  • And finally, the culinary techniques we suggest are healthy styles such as roasting, boiling and papillote

In any case, a healthy diet with high vegetable content has been shown to be associated with a lower incidence of these pathologies.

Dietary treatment for biliary lithiasis

In people with biliary lithiasis, correct nutrition plays a fundamental role, since it facilitates the recovery process, favoring the rest of the gallbladder and facilitating digestive functions. Moreover, it helps prevent complications associated with this disease.

In other words, the gallbladder diet can undeniably help prevent the acute symptoms of biliary colic and relieve digestive discomforts such as gas and dyspepsia. In the case of inflammation (cholecystitis), fasting is advisable, provided that the physician indicates it.

A variety of food.
A diet low in fat and free of inflammatory foods can help speed recovery from gallstones. It’s even key to controlling your symptoms.
