3. Celiac Disease
People who are allergic to gluten may experience stool that is runny and yellow. Some people have a minor allergy to gluten, while others have what is called celiac disease. When a person who has celiac disease eats gluten, which is a protein that is found in barley, rye, and wheat, the immune system will respond by starting to attack the tissues located in the small intestine. This response from the immune system causes the tissues to become damaged. When the tissues of the intestine are damaged, the ability to absorb nutrients by the intestines is compromised. Along with yellow stool, a person with celiac disease might also experience constipation, diarrhea, fatigue, depression, headaches, bloating, and nausea. If you are experiencing these symptoms, it is important to find the underlying cause. Your doctor will help you come up with a diet and a plan to help control this issue if it is the cause of your yellow stool.
4. Pancreas
The pancreas is also an important part of the digestive system. One of the things that the pancreas does is release enzymes. These enzymes help to support normal poop. If you are having issues with your pancreas, you might experience stool that is yellow in color. In addition, issues with the pancreas can cause your bowel to have a floaty or frothy appearance. You might also notice an odor that is more foul than normal. One of the issues that you might experience with the pancreas is an infection. Inflammation of the pancreas might be causing the issue as well. Stones can develop and block the ducts that come out of the pancreas, which can cause inflammation and other issues. It also could be a sign of pancreatic cancer. If you are experiencing a yellowish stool that is foamy and smells bad, it is a good idea to discuss this issue with your doctor to determine the underlying cause.
