Certain foods, such as eggs, garlic, legumes, and dairy, are hard to digest and can cause gas. In turn, this makes your stool extra pungent. Other times, the problem may be from an abundance of bad bacteria in your gut, a viral infection, or Clostridioides difficile—a bacterium that causes diarrhea.
Viral or bacterial infections and parasitic infections can affect digestion and cause foul-smelling stool or diarrhea. These include: Salmonella: This is a bacterial infection that can cause foul-smelling diarrhea. Giardiasis: Giardia is a protozoa-type parasite that can cause diarrhea with foul stool.
Stools normally have an unpleasant odor. Most of the time, the odor is familiar. Stools that have an extremely bad, abnormal odor may be due to certain medical conditions. Foul-smelling stools also have normal causes, such as diet changes.
Certain types of bacteria in the large or small intestines may also make high levels of ammonia. Therefore, stool that smells like ammonia may be a sign of an imbalance between “good” and “bad” bacteria in your digestive system.
Rotavirus often begins with a mild fever and is followed by vomiting and an upset stomach, as well as increased amounts of watery diarrhea many times a day. Anyone caring for small children should know the symptoms of rotavirus, including: Frequent, watery diarrhea (often foul-smelling, green or brown)
Symptoms last for about 2 weeks. Uncooked food, fruit and vegetables. Foul smelling greasy or watery diarrhoea, stomach cramps, nausea, fatigue, bloating, and loss of appetite.
Diarrhea speeds up the digestion process, so foods often do not break down fully. This means that stomach acids, digestive enzymes, and bile may still be present in diarrhea. These can damage the tissues and cause a burning sensation in the rectum during or after a bowel movement.

Yellow stool may indicate a malabsorption disorder caused by a parasite, illness, or disease. Malabsorption of fat can lead to an increased fat content in stools, which can be pale, large, foul-smelling, and loose.

If your poop... Smells like sulfur or eggs and you have diarrhea. It may mean: You could have giardia. The parasite tends to hang out in fresh water, so if you went swimming in a lake, have gone camping, or drank unpurified water recently, you may have picked up the bug along the way.
cholerae express cholera toxin (CT) within the intestinal lumen, resulting in increased cAMP levels in intestinal epithelial cells and pumping of Cl− (and therefore Na+ and H20) into the intestinal lumen and secretory diarrhea. Total flushing of the intestinal tract leads to “rice water” stool with a fishy odor.
Occasional foul-smelling stool may not require any treatment. But if it continues or you also have other symptoms, like runny stool, more frequent bowel movements, nausea, vomiting, or stomach pain—see your doctor.
Unintended weight loss can sometimes result from persistent or chronic diarrhea—aka diarrhea that lasts for more than two weeks—but it's not something to aspire to.

Foul-smelling stools may also be a sign of an intestinal viral, bacterial (like E. coli or Salmonella), or parasitic infection. These infections can occur after eating contaminated food or drinking contaminated water (which can also happen when swimming).
However, the key distinction is time: The symptoms of a stomach bug will take 12 to 48 hours to develop, while the symptoms of food poisoning typically develop much faster, usually with 6 hours of consuming an infected dish. Another common difference between the two is the length of illness.
