Keto And Gallbladder: Is This Diet Harmful?

The ketogenic diet is a popular weight-loss strategy, but it has been linked to adverse effects on gallbladder health. The gallbladder, a small organ located beneath the liver, stores bile, a fluid that aids in fat digestion. While the keto diet's high-fat content can be concerning for those without a gallbladder, it is possible to follow with adjustments. The keto diet's impact on gallbladder health is a complex issue, with some evidence suggesting a link to gallstone formation and attacks, while other studies indicate that a low-fat diet may actually increase the risk of gallstones.

The gallbladder's role in digestion

The gallbladder is a small, pear-shaped organ located on the right side of the abdomen, just beneath the liver. It is only about 3 to 4 inches long and 1 inch wide, but it plays a crucial role in digestion and getting energy from food.

The gallbladder's main function is to store and concentrate bile, a digestive juice produced by the liver. Bile helps break down fats in the food we eat, which is the hardest part of digestion. Carbohydrates and proteins tend to break down more easily. Bile is composed mainly of water, but it also contains bile salts, cholesterol, certain fats (such as lecithin), and bile pigments.

During digestion, the bile produced by the liver flows directly into the small intestine. When we are not eating, or fasting, about 75% of the bile flows into the gallbladder for storage until it is needed again. The gallbladder absorbs most of the water content, making the bile more concentrated. When we eat, especially fatty foods, the gallbladder contracts and releases bile through the bile duct into the small intestine, where it mixes with semi-digested food.

The bile breaks down fat globules into small droplets, which can then be processed and broken down further by digestive enzymes from the pancreas. The bile salts also help the cells in the bowel to absorb these fat droplets. This process is essential for getting energy from food, as it allows the body to absorb and use the broken-down fats.

While the gallbladder is not a vital organ, and people can live without it, it plays a key role in digestion and maintaining gallbladder health is important to avoid issues such as gallstones, cholecystitis, and other gallbladder-related conditions.

Bile production and storage

Bile is a yellow, brownish or olive-green fluid that helps the body digest fats. It is made up of water, bile salts, cholesterol, certain fats (lecithin) and bile pigments. The main bile pigment, bilirubin, is what makes urine yellow and stool brown.

The gallbladder is located right underneath the liver. It is a small, pear-shaped organ that stores and releases bile. The gallbladder does not produce bile; the liver does. The gallbladder just stores it. The cells of the liver produce about 800 to 1,000 milliliters of bile every day. Between meals, when there is no fat that needs to be digested, most of the bile flows into the gallbladder, where it is concentrated and stored. The gallbladder usually holds about 30 to 80 milliliters of fluid. When we eat fatty foods, the gallbladder contracts and squeezes bile through the bile duct. The bile duct is composed of three branches, which are arranged into the shape of the letter Y. The bile is mixed into the semi-digested food in the duodenum, the first part of the small intestine.

Bile salts break down larger fat globules in food into small droplets of fat. Smaller fat droplets are easier for the digestive enzymes from the pancreas to process and break down. The bile salts also help the cells in the bowel to absorb these fat droplets.

The ketogenic diet can affect the gallbladder in several ways. Frequent fasting has the effect of slowing bile production and usage. This leads to stagnant bile that eventually turns to sludge and gallstones. While gallstones are often composed of cholesterol, the main source of cholesterol-type gallstones is excessive protein consumption. The more excess proteins, the more congestion in the liver, eventually leading to fatty liver conditions and gallstone formation.

Keto and gallbladder removal

The gallbladder is a small sac located just beneath the liver. Its primary function is to store bile, a green fluid that helps with fat digestion. The gallbladder doesn't produce bile—the liver does—but it does help to break down dietary fats.

Gallbladder surgery (or cholecystectomy) is sometimes medically recommended when gallstones are present and causing abdominal pain and cramping. After gallbladder removal, bile flows directly from the liver into the intestine. While digestion is still possible without a gallbladder, there won't be as much bile, and it won't be as concentrated, which can lead to digestive issues.

Around 50% of patients experience digestive symptoms after gallbladder removal surgery, the most common side effect being diarrhea and loose stools. This is due to the more continuous release of bile into the intestines, which controls the speed of food moving through the intestine.

If you follow a keto diet, which is high in fat, and don't have a gallbladder, your liver has to work harder to produce more bile. This can result in unpleasant side effects such as diarrhea or gastrointestinal distress (cramps, gas, bloating, etc.). It can also lead to a deficiency in fat-soluble vitamins A, D, E, and K.

So, can you follow a keto diet after gallbladder removal? The answer is yes, but with some adjustments. Here are some tips to help you follow a keto diet happily and healthily:

• Start with clear liquids and easy-to-digest foods for the first few days after surgery. Gradually add more solid foods back into your diet.
• Eat smaller meals more frequently until your body adapts to higher-fat meals.
• Consume foods high in soluble fiber, such as low-carb vegetables or keto bread, with your meals.
• Take an ox bile supplement to aid in the digestion of higher-fat meals.
• Find your personal "sweet spot" for fat consumption by measuring your ketones frequently and adjusting your diet accordingly.
• Consume soluble fiber along with fats. Good keto sources of soluble fiber include Brussels sprouts, avocado, broccoli, sunflower seeds, and hazelnuts.
• Modulate the types of fats you consume. Long-chain fatty acids (such as animal fats and olive oil) require bile, while medium-chain triglycerides (MCTs) do not. MCT oil is easily digested and popular in the keto community.
• Take supplements that aid in fat digestion, such as digestive enzymes and bile salts.

By following these steps, you can help ensure that you're getting the benefits of the keto diet while maintaining healthy digestion and nutrient absorption, even without a gallbladder.

Adjusting keto after gallbladder removal

The gallbladder is a small sac located just beneath the liver. Its primary function is to store bile, a fluid that helps with fat digestion. The gallbladder is not responsible for producing bile—that's the liver's job. However, the gallbladder does play a crucial role in making the bile more concentrated and effective.

After gallbladder removal, the bile made by the liver can no longer be stored between meals. It flows directly into the intestine, and while there is enough bile to allow for fat digestion, there is not as much as before, and it is less concentrated. This can lead to digestive issues such as diarrhea and discomfort.

• Start low and go slow: Begin with a moderate amount of fat and slowly reduce carbs simultaneously. Continue to adjust as tolerated, working your way towards ketosis over about a month.
• Stay hydrated but be mindful of when you drink: Avoid drinking fluids during mealtimes and 30 minutes before and after eating, as this may flush out the enzymes responsible for digesting your food.
• Choose Medium-Chain Triglycerides (MCTs) over other fats: MCTs are a type of fat that does not require bile to be digested and absorbed. MCT oil is available at most grocery stores and online. Note that MCT oil is not for cooking; instead, add it to foods or beverages after cooking, or take it like a supplement.
• Pair fat with soluble fibre: Soluble fibre helps to slow down digestion, allowing for better absorption of nutrients. Some keto-friendly sources of soluble fibre include pumpkin seeds, sunflower seeds, flax seeds, chia seeds, Brussels sprouts, avocado, broccoli, and hazelnuts.
• Consume smaller, more frequent meals: This may allow for a better distribution of bile to dietary fat, resulting in improved digestion and absorption of nutrients. People without a gallbladder may struggle with longer intermittent fasting approaches.
• Consider supplements: Digestive enzymes and bile salts, available over the counter, can aid in the digestion of fats.
• Try consuming ginger: Research has found that ginger and other spice compounds can enhance fat digestion.
• Utilise shakes: Smoothies and supplemental shakes are often easier to digest as they are already in a blended/drinkable form, requiring less work from the gut. Homemade keto shakes are a good way to incorporate MCT oil, protein, and fibre.

Remember, always speak to your doctor before making big dietary changes, especially right after surgery or with any medical history.

Keto and gallstones

The gallbladder is a small sac located just beneath the liver. Its primary function is to store bile, a green fluid that helps with fat digestion. The gallbladder doesn't produce bile—the liver does—but it does help to break down dietary fats.

The keto diet is a low-carb, moderate-protein, high-fat diet that many people follow for weight loss, increased energy, reduced blood sugar, and other health benefits. The diet puts the body into a state of "ketosis", meaning that most of the body's energy comes from burning fat stores instead of sugar.

So, what happens when you combine a diet high in fat with the absence of a gallbladder? Is it dangerous? Can it cause gallstones?

Firstly, it is possible to follow a keto diet without a gallbladder. The bile that is made by the liver can still flow directly into the intestine and aid in fat digestion, even without the gallbladder's storage function. However, there will be less bile, and it will not be as concentrated, which can lead to digestive issues such as diarrhea and loose stools.

If you wish to follow a ketogenic diet after gallbladder removal surgery, it is recommended to start with clear liquids and easy-to-digest foods for the first few days. After that, gradually add more solid foods back into your diet, eating smaller meals more frequently until your body adapts to higher-fat meals. It is also recommended to consume foods high in soluble fiber, such as low-carb vegetables, and to consider taking an ox bile supplement to aid digestion.

Now, onto gallstones. Interestingly, avoiding fat does not decrease your risk of gallstones—it increases it. This is because when you eat low-fat foods, less bile is needed to digest your food, so more bile stays in the gallbladder. This stagnant bile can eventually turn into sludge and gallstones. On the other hand, eating regular meals with fat in them helps to flush out the bile ducts and the gallbladder, preventing gallstones from forming.

However, if you already have gallstones and you eat a high-fat meal, there is a risk that a gallstone could get stuck on its way to the intestines, causing a gallstone attack and abdominal pain. This is a risk to be aware of, and it is always recommended to discuss any significant changes in diet with your doctor.

In conclusion, while it is possible to follow a keto diet without a gallbladder, there are some important adjustments to be aware of to ensure it is done healthily. Additionally, while a keto diet may help to prevent gallstones in the long term by flushing out the bile ducts, it may also trigger gallstone attacks if gallstones are already present. As always, it is important to consult a medical professional before making any major dietary changes.
