The primary role of bile is to break down fat. Without it, your body is unable to process the fat in food. Although people sometimes equate fat with bad, fat is absolutely necessary to keep us alive. And, in fact, many vital nutrients, including vitamins A, D, E, and K, are fat-soluble. That means that they are absorbed along with the fat in food and are stored in fatty tissue in the body. Vitamin A is important for healthy bones and skin. Vitamin D is necessary to absorb calcium and is vital for bone health, while vitamins E and K promote healthy blood. Deficiencies of these fat-soluble vitamins aren’t just potential signs of gallbladder issues. They’re also serious health conditions in their own right. Vitamin A deficiency causes blindness and makes you more vulnerable to infections. Lack of vitamin D causes muscle pain and bone loss. Vitamin E deficiency can cause nerve damage, while too little vitamin K leads to increased bruising and bleeding. If you don’t have enough bile, you won’t be able to absorb these nutrients properly.
