What Causes Foul Smelling Gas and Stool?

The foods individuals eat and the microorganisms in their colons frequently cause unpleasant-smelling feces. However, rotten-smelling feces may also be a sign of a significant medical issue. It’s possible for diarrhea, bloating, or flatulence to accompany bad-smelling stools. These stools are frequently watery or soft.

What causes foul-smelling gas and stool? Many different factors could be to blame for this unpleasant condition. Inflammatory bowel disease, high iron intake, and lactose intolerance are some possible causes. However, if you don’t have a severe underlying disease or health condition, a change in your diet might be the answer. This article will give you some valuable tips for fixing this problem.

Lactose intolerance

You may have lactose intolerance if you have a problem with foul-smelling poop. It is a digestive disorder where the body cannot process lactose, a sugar found in milk. The resulting gas, bloating, and painful abdominal cramps may be associated with the condition. Additionally, your breath may smell bad. The symptoms of lactose intolerance can be correlated to the amount of lactose in your diet.

The problem is caused by undigested lactose, which hangs around in the small intestine. This fermented lactose causes the release of gas, including hydrogen, carbon dioxide, and methane. Gas produced from lactose isn’t odorless and is caused by the fermentation of undigested protein in the gut.

Symptoms of lactose intolerance can be triggered by consuming about 12 grams of milk or a cup of ice cream. If you experience these symptoms regularly, you should visit your doctor. They will probably ask you to stop eating dairy for a few weeks. If this doesn’t work, your symptoms may improve and return once you reintroduce dairy products.

In addition to the symptoms mentioned above, you may also experience constipation. Constipation is the opposite of diarrhea and involves passing harder stools. Additionally, the condition may also be accompanied by excessive straining during defecation. This is because the fermentation of the undigested lactose leads to methane production, which slows food movement through the gut.

High iron diets

If you have noticed that your stools are often odorous, there may be something wrong with your digestion. Bacteria may cause foul-smelling stools. In rare cases, they may signify a more serious underlying condition. You should seek medical attention if the odor persists or if you notice other symptoms like diarrhea and flatulence. Foul-smelling stools are common in the digestive system and are often caused by malabsorption. This happens when your body fails to absorb certain nutrients from your food. Disease and infection can prevent the proper absorption of nutrients from your diet.

Symptoms of IBD include foul-smelling poop. People with this condition often suffer from constipation or diarrhea, as well as gas and abdominal pain. The odor can also be caused by specific foods or an imbalance in your gut’s microbiome. A poor balance of microorganisms in your digestive tract can cause foul-smelling stools and gas. If your symptoms worsen over time, your doctor may recommend a high-iron diet or take additional medications to improve your health.


The cause of foul-smelling gas and diarrhea is unknown. However, several factors could contribute to the problem. One common symptom is chronic diarrhea. If your symptoms persist, you should consult a doctor. The underlying cause may be a food intolerance or an infection. In either case, lifestyle changes may be able to relieve the symptoms. In addition, a lack of bowel movements may be an indication of malabsorption.

What Causes Foul Smelling Gas and Stool?

Chronic diarrhea, abdominal bloating, and weight loss are all signs of malabsorption. The absorption of too much sulfur may cause foul-smelling stools. Sulfur-metabolizing bacteria break down these foods into odorless hydrogen, carbon dioxide, and sulfide. This is why your stools often smell so bad. The cause of foul-smelling poop is still not entirely known.

Testing for malabsorption begins with an extensive physical examination. The examiner will note any abnormalities, such as undigested food fragments or excess fat. In some cases, the presence of parasites or intestinal growth indicates malnutrition. In such cases, a blood test may also be necessary. These tests can indicate specific malabsorptive conditions or can be used to rule out other causes of the problem.

If the foul-smelling stools continue, you should seek medical attention immediately. The problem could be a bacterial infection. In such a case, it is vital to follow good hygiene practices. Washing hands before preparing food is crucial. Cooking produce is also an essential factor. Using separate cutting boards for vegetables and meat is also recommended. Lastly, check if you’re taking any medications or supplements before consuming foods with foul-smelling odors.

Metal-smelling poop

If you are experiencing metallic-smelling gas and stool, there are several causes. Some are harmless and will go away on their own, while others are causes for concern. Sometimes, the stool and gas smell like metal because of your diet or medication. In other cases, the stool may be accompanied by blood or an infection of the kidney or liver. If you suspect your poop and gas smell like metal, contact a doctor for a diagnosis.

The cause of metallic-smelling poop and gas may be gastrointestinal bleeding. In addition, it may be caused by various diseases, including ulcers, Crohn’s disease, Barrett’s esophagus, or a foreign object lodged in the gastrointestinal tract. Other causes of metal-smelling gas and stool include certain medications or an allergy to metals. Iron poisoning is an uncommon cause of this condition.

The causes of metal-smelling feces and gas can vary, but the symptoms are often the same. Eating certain foods may cause your bowels to produce sulfur-containing gases. Other causes include ingestion of foods that are high in iron or sulfur. If you suspect your bowels aren’t absorbing nutrients properly, consult a doctor. If you’re experiencing metallic-smelling gas and stool, your doctor may recommend a low-FODMAP diet to reduce your symptoms.

Symptoms of colorectal cancer

Symptoms of colorectal cancer can vary depending on the tumor’s location, the type of colon cancer, and the extent of spread. In the early stages, a blockage in the right side of the colon is usually only noticeable to those with advanced cancer. Because the colon is so large and has such a thin wall, most of the material passing through the colon is liquid. Some tumors can be felt by touch, but they are usually invisible. In the late stages, patients may experience abdominal cramps similar to menstrual symptoms.

Regardless of the cause, symptoms of colon cancer should be taken seriously. If you notice any of these signs, contact your doctor immediately for a thorough exam. Remember, it’s always better to detect colorectal cancer in its early stages than later. More than 90% of cases are curable if discovered in their early stages. A doctor at UnityPoint Health – St. Luke’s Hospital in Minneapolis can give you an accurate diagnosis and recommendations for treatment.

If you notice dark stools that don’t smell bad, they could indicate colon cancer. Blood in the stools can also be a sign of colon cancer. Bright red streaks, clots, or dark purplish blood are signs of colon cancer. If blood is detected, a stool sample can be sent for a fecal occult blood test.
