There are a few reasons why poop might smell like onions. If you eat a lot of onions, for example, your poop will likely smell like onions. Other foods can also cause your poop to smell strongly. For instance, garlic and fish are both notorious for causing strong-smelling poop. Some medical conditions can also cause your stool to smell like onions. One example is celiac disease, which is caused by an intolerance to gluten. If you have celiac disease, consuming gluten will cause your stool to smell bad.
What does the smell of your poop indicate?
The odor of your poop can indicate changes in your diet. Even if your stool smells extremely foul, it could be due to something you ate. However, an unusually foul smell could also be a sign of a disease, disorder or condition. For example, celiac disease, Crohn’s disease, cystic fibrosis, and intestinal infections can all cause foul-smelling stools.
Why does stool smell like garlic?
When you eat foods that are high in sulfur—such as meats, dairy, garlic, and cruciferous veggies (think: broccoli, cabbage, kale)—your gut works overtime to digest them and produces a larger amount of the gasses that make your poop smell.
What determines what your poop smells like?
There are many factors that can cause stool to smell foul. Such as the food people eat, their allergies, medication they take, infections, and any underlying medical conditions. All of these things can contribute to how strong or faint the odor is. When it comes to what somebody eats, high protein foods like meats and cheeses can make poop smell worse because they produce sulfur as they break down in the gut. Fiber-rich foods like fruits, vegetables, and grains can make stool smell better because they help the body absorb more water and produce bulkier stools.
Why do I smell onions?
There are a few potential explanations for why someone might smell onions when there are none present. One possibility is that they are experiencing an olfactory hallucination, which is when you detect smells that aren’t really there in your environment. The odors you notice in phantosmia can differ from person to person and may be foul or pleasant. Another possibility is that the person has a condition called parosmia, which is a distorted sense of smell. This can cause familiar smells to become altered or changed, making them unpleasant. If you’re concerned about why you’re smelling onions when there shouldn’t be any around, it’s best to consult with a doctor to rule out any underlying medical conditions.
Does your poop smell matter?

This infection is caused by the overgrowth of the bacterium Clostridioides difficile in the intestine. Symptoms of this infection include watery diarrhea, abdominal pain, cramping, bloating, and gas. The infection can also lead to fever, weight loss, and dehydration. If you think you may have this infection, it is important to see a doctor so that you can be treated.
