People with bad gallbladder should usually avoid eating some high-fat and high-cholesterol foods, and should also eat less spicy and stimulating foods. 1. High-fat food: After consuming greasy and high-fat food, patients will experience indigestion due to their poor gallbladder function. At the same time, patients often also feel hidden pain in the abdomen after consuming these foods. Common high-fat foods include fatty meat, fried foods, etc. 2. High cholesterol foods: Cholesterol is an important raw material for the formation of gallstones, and a large amount of cholesterol intake and deposition will lead to increased chances of gallstone formation. Common high cholesterol foods include egg yolks and animal offal. 3. Spicy and stimulating food: such as spicy food, alcohol, coffee, etc., these foods will promote the contraction of the gallbladder, which will bring discomfort to people with poor gallbladder function. For patients with gallbladder disease, they should go to the relevant departments of regular hospitals and be treated under the guidance of professional physicians to avoid delaying their condition.
