From the Guidelines

After gallbladder removal, to reduce diarrhea, follow a low-fat diet by limiting fat intake to 40-50 grams daily, as this can help minimize the irritation caused by bile flowing continuously into the intestine 1. To manage diarrhea effectively, consider the following key points:

  • Start with small, frequent meals and gradually reintroduce fats to allow your body to adjust to the new digestive process.
  • Focus on lean proteins (chicken, fish, turkey), non-fat dairy, whole grains, fruits, and vegetables to maintain a balanced diet.
  • Avoid fried foods, fatty meats, full-fat dairy, creamy sauces, and high-fat desserts, as they can exacerbate diarrhea.
  • Increase fiber intake slowly to add bulk to stools, which can help reduce the frequency of diarrhea.
  • Stay well-hydrated with water and clear fluids to prevent dehydration.
  • Consider taking a bile acid sequestrant like cholestyramine if dietary changes aren't sufficient, as it has been shown to be effective in managing bile acid diarrhea in patients post-cholecystectomy 1. It's essential to note that post-cholecystectomy diarrhea occurs because without a gallbladder, bile flows continuously into the intestine rather than being released in controlled amounts during meals, causing irritation and faster transit time. Most people find their symptoms improve within weeks to months as the body adapts to the absence of the gallbladder.

From the Research

Diet for Less Diarrhea After Gallbladder Removal

To manage diarrhea after gallbladder removal, several studies suggest the following:

  • A trial of a bile acid binder such as cholestyramine or colestipol may benefit patients with postcholecystectomy diarrhea 2
  • Cholestyramine resin therapy can resolve diarrhea in patients with elevated fecal bile-acid excretion 3
  • Bile acid diarrhea (BAD) can occur due to disruption to the enterohepatic circulation after cholecystectomy, but the mechanism is unknown 4
  • A significant correlation was found between gallbladder PPARα concentration and stool consistency, with lower PPARα concentration associated with looser stool 4

Treatment Options

Treatment options for postcholecystectomy diarrhea include:

  • Cholestyramine, which can control chronic diarrhea and has been shown to be effective in several studies 5, 2, 3
  • Colestyramine, which has a pooled response rate of 79% in patients with bile acid diarrhea 6
  • Bile acid binders, which can help manage bile acid diarrhea in patients with previous cholecystectomy 6

Prevalence of Bile Acid Diarrhea

The prevalence of bile acid diarrhea in patients with chronic watery diarrhea and previous cholecystectomy is estimated to be around 70% 6
