[The necessity for intragroup individualization of diet No. 5 in hepatobiliary diseases].

The frequency of cholelithiasis in Bulgaria has increased 9 times for the last 15 years. At the same time 40.5% of the patients with cholelithiasis are obese--II-IV degree of obesity. This fact calls for individualization of diet No 5 which in this country is applied to patients with liver and biliary diseases. A variant diet No 5-x for patients with cholelithiasis and abnormal body mass is proposed. This diet keeps the protein and fat components of diet No 5 but reduces the carbohydrates quantity from 346 g to 195-200 g which leads to the reduction of the daily intake of calories from 2369-2450 to 1700. The individualization of diet No 5 and the introduction of diet No 5-x in patients with biliary diseases will ensure a greater prophylactic and therapeutic efficacy of the dietetic treatment of patients with cholelithiasis and other biliary diseases combined with various degree of obesity.
