Diarrhea After Gallbladder Removal

Why does diarrhea develop after gallbladder removal?

Diarrhea can develop in up to 36% of people who have had their gallbladders removed [1,3,4].

The bile, which is formed in the liver, is normally stored and concentrated in the gallbladder. After meals, the bile is squeezed from the gallbladder into the small intestine where it helps to digest fat. After gallbladder removal, the bile cannot be stored in the gallbladder, so it constantly flows into the intestine, even when there is no food in it, so it can irritate it and trigger urgent watery diarrhea [10].

What does green or yellow diarrhea mean?

When the bile travels through the intestine, the normal intestinal bacteria gradually change its color from green to bright yellow and finally to the usual brown color in the stool. After gallbladder removal, the bile constantly flows into the intestine and stimulates its motility, which makes the bile travel faster and appear in the stool in its original green or yellow color. Also, because of the increased intestinal motility, water travels through the intestine faster, less of it is absorbed and more of it appears in the stool.

NOTE: Green or yellow diarrhea can also occur in other conditions with increased intestinal motility.

How long does diarrhea after gallbladder removal last?

Diarrhea after gallbladder removal in most cases lasts for 4-8 weeks, but in some, it can become chronic and persist for several years [1,8].

How can you know if diarrhea is triggered by gallbladder removal?

In diarrhea after gallbladder removal, less bile acids from the bile will be absorbed, so more of them will appear in the stool, which can be detected by the  75SeHCAT test [13].

Rarely, a retained stone or stricture in the bile duct after gallbladder removal blocks the delivery of the bile into the intestine. This results in improper digestion and absorption of fats, which therefore appear in the stool and make it white, sticky and floating. This is called steatorrhea, which can be detected by the fecal fat test.


The following drugs and supplements can help to control diarrhea after gallbladder removal [1,14]:

  • An over-the-counter anti-diarrheal drug loperamide
  • Bile acid binders:
    • Cholestyramine (common side effects: stomach pain, nausea, vomiting, heartburn) [2,3,5]
    • Colestipol and colesevelam (fewer side effects than cholestyramine) [1,2]
    • Diphenoxylate and atropine [4]
  • Blond psyllium – a dietary fiber supplement [6,7]

Probiotics may be moderately effective in controlling diarrhea in irritable bowel syndrome [11] and infectious diarrhea [12], but it is not clear if they also help in diarrhea after gallbladder removal.


To prevent or limit diarrhea after gallbladder removal [15]:

  • Have small and frequent meals, so the bile will mix with the food and will irritate the intestine less.
  • Eat foods high in slow carbohydrates, such as whole-grain bread, brown rice and low-sugar breakfast cereals, and foods high in protein but low in fat, such as skinless poultry and fish, like cod, grouper, halibut and tilapia.
  • Do not drink liquids during or after but between the meals.

If you have diarrhea, drink enough water to replace the lost fluid. Drink as much as needed to prevent dehydration (thirst, dry, mouth, dark yellow urine).

Foods to Avoid

If you are experiencing diarrhea, bloating or excessive gas, limit [1]:

  • Foods high in fats, such as oils, cheese, butter, French fries, potato chips, chocolate, lard, gravies, fatty meats (bologna, sausage, chicken skin) and fish (salmon, sardines…), pizza, hamburgers, pies and nuts [9]
  • Foods high in FODMAPs (Fermentable, Oligo-, Di- and Monosaccharides and Polyols)
    • Foods high in soluble fiber: oats, barley, legumes, prunes, artichokes, asparagus, psyllium husk
    • Foods high in lactose: milk, yogurt, sweet stout, whey powder
    • Foods high in fructose: apples, pears, mangoes, honey
    • Foods high in sorbitol: prunes, sugar-free chewing gum, low-calorie soft drinks
  • Spicy foods
  • Caffeinated beverages: coffee, tea, cola, energy drinks
  • Alcohol

    Forgot to mention – I rarely drink milk. All I have to do is eat food and within less than 15 minutes I must get to the bathroom – gas pains and watery diarrhea.

    • Jan Modric says:

      Some general diet tips are described above in the article and I also shortly mentioned a low-FODMAP diet. In this diet you limit foods that commonly cause gas and diarrhea: legumes, oats, milk, foods high in fructose (apples, pears, honey…). They are more detailed descriptions of low-FODMAP diet online available. I’m not saying that this will help in your case. You want to experiment with individual foods and eliminate them from your diet one by one for 4 days and see if it helps.

      You can also have a stool test for the presence of bile, which shows if diarrhea is caused by excessive bile in the stool or not.

  2. Eleanor White says:

    Thank you for your response Jan. I am not lactose intolerant as far as I know. What is a lot FODMAP diet. I’ll try anything. Weight down to 103 pounds and only leave the house if I have a doctor appointment.

  3. Eleanor White says:

    Please notify me if this article is updated. Forty years after gallbladder removal, I am still searching for something that works. Doctor suggested Probiotics today, along with Benefiber and a dairy free diet.

    • Jan Modric says:

      Do you want to describe exact symptoms? Dairy-free diet can help if you are lactose intolerant (bloating/diarrhea after drinking milk). A broader diet called a low-FODMAP diet may be even better.
