Why do my fingers smell like poop


Do you ever wonder why your fingers smell like poop? It is certainly not the most pleasant odor and can be extremely embarrassing in public. You may have tried washing your hands, using perfumes or colognes, and even soaps but it doesn’t seem to do much, which can be quite frustrating. This article will explain the possible causes of why the strange oder clings to your digits and what you should do about it.

The most common cause for this phenomenon is a metabolic disorder called Trimethylaminuria (TMAU), which is often referred to as “Fish Odor Syndrome”. This condition occurs when there is an enzyme deficiency in the body that inhibits it from converting trimethylamine (TMA) into its odorless form. People suffering from this disorder produce a significant amount of TMA in their urine, sweat, and breath. Normally, TMA breaks down before being released from our bodies but when someone is deficient in flavin monooxygenases (FMO) enzymes they are unable to break down TMA properly or convert it into its odorless form. This causes an array of smelly issues such as bad breath and body odor emanating from non-sweating areas such as feet and fingers.

Another potential cause for smelly fingers is poor hygiene practices coupled with sweat accumulation between the toes or on the feet itself which could give of a peculiar smell if not cleaned well enough. Poor dental hygiene leading to excess bacteria buildup on tooth surfaces has been linked with bad breath and even with finger odors due to residue stored in fingernails. Certain foods such as garlic or onions have an affinity for spreading odors through skin contact – if these frequently make their way onto your hands it could explain why you’re emitting a smelly stench every time you wave them around!


Have you ever noticed that your fingers have a strange odor that smells like poop? This can be a rather unpleasant and embarrassing experience, so it’s understandable that you might be wondering what the cause is.

Fortunately, there are a few potential causes for why your fingers might be smelling like poop. In this article, we’ll be discussing some of the potential causes and how you can address them:

Bacterial Overgrowth

Bacterial overgrowth is the most common cause of fingers that have a foul odor. The human body is full of bacteria, and many are important for healthy functioning. However, when bacteria overgrow in some areas of the body, it can lead to unpleasant odors and potentially health problems. Small amounts of certain types of bacteria produce an odor very similar to poop or sulfur when they break down proteins in the skin. Although this usually occurs on the hands, it can occasionally occur on other parts of the body as well.

Bacterial overgrowth can be caused by a number of factors including:

  • Excessive sweating
  • Poor hygiene practices such as not washing hands after using the bathroom
  • Skin conditions such as eczema or psoriasis
  • Anxiety or stress which can cause sweat production rates to increase

It is important to consult a doctor if you are experiencing persistent foul smelling hands as it may be indicative of an underlying condition that needs treatment.

Eating Certain Foods

Eating certain types of foods can lead to your fingers and other body parts smelling like poop. The sulfur compounds found in some food items, such as garlic and onions, are often released through the skin, resulting in a foul odor. Eating too much processed meat or eggs can also cause this type of smell because these foods contain high levels of sulfur. Additionally, exposure to pollutants can be absorbed into the body through the skin and pores, causing odors like fecal matter.

To try and avoid smells from food, you should become aware of what you’re eating and try to limit your consumption of these foods:

  • Garlic
  • Onions
  • Processed meat
  • Eggs

Poor Hygiene

Poor hygiene is one of the most common causes of smelly fingers. When you don’t wash your hands properly, bacteria can build up. These microorganisms produce gases that cause an unpleasant odor. Additionally, if you don’t wash your hands often enough, the sweat and oils from your hands can be collected by dirt and bacteria, making your fingers smell bad.

Poor diet can also lead to smelly fingers. Eating too much sugar or fried foods can affect the way sweat smells when it is released by the skin on your hands. Make sure to choose healthy, balanced meals and drink plenty of water to reduce bad odors.

Smoking cigarettes or other tobacco products has also been linked to smelly fingertips. Chemicals in cigarettes interact with sweat and create a pungent smell that is hard to get rid of even after washing your hands with soap and water. Regularly using hand sanitizer or hand wipes may help remove some of this odor as well as help keep germs at bay between regular handwashing times throughout the day.

Medical Conditions

Certain medical conditions which can lead to fingers smelling like feces include:

  • Kidney and liver diseases
  • Crohn’s disease
  • Mesenteric ischemia
  • Anal fistulas
  • Intestinal obstruction

These conditions cause an imbalance of electrolytes in the body that leads to the unpleasant smell of fecal matter on the hands.

Other less serious causes that may cause fingers to smell like excrement include:

  • Poor hygiene
  • Handling organic compounds like grass clippings and manure
  • Not washing hands after using the bathroom or coming into contact with another person’s fecal matter.
  • Eating certain foods such as corn or beans may also cause a strong smell due to undigested proteins passing through the intestines.

If your hands are smelling unusually bad for no apparent reason and there is no medical explanation available, it could be a sign of a vitamin deficiency or nutrient imbalance in your diet. Specific nutritional deficiencies associated with this symptom include inadequate intakes of zinc, magnesium, selenium and iron. If you think you might be deficient in any one of these nutrients, consult your physician for further advice and steps to take.


If you have noticed that your fingers smell like poop, it is important to identify the cause of the smell in order to determine the best course of action. The most common causes of fingers smelling like poop are bacteria and fungal infections, allergies, and poor hygiene. Treatments can range from simple home remedies to more aggressive medical treatments. We will explore all of the potential treatments in this article.

The potential treatments for fingers smelling like poop include:

  • Simple home remedies
  • More aggressive medical treatments

Improving Hygiene

Good hygiene is an important step in reducing bad smells from finger surfaces. Washing hands regularly with soap and warm water is the best way to keep odors away. Using a natural hand cleanser such as aloe vera or baking soda can also help keep hands clean and smelling fresh.

For surfaces that are exposed to the environment frequently, it is recommended to use an antibacterial cleanser before touching any food or items that will come in contact with skin.

Using a barrier cream between finger tips and surfaces (e.g. anything you have to touch) can also help keep malodorous residues away and prevent them from lingering on your hands or other items you come in contact with. The advantage of using these products is that they are easy to apply and will provide some protection against germs and bacteria, while at the same time reducing the amount of bacteria able to pass through onto your skin surface.

Keeping your hands dry is also essential for keeping bad smells at bay; moisture on fingers can encourage the growth of certain odour-causing bacteria, so be sure to wash them thoroughly after they have been exposed to wet surfaces or liquids. You may also want to consider:

  • Wearing rubber gloves when cleaning or working with greasy substances since this material decreases exposure of skin surface area for bacteria attack by acting as a protective barrier between them and your skin.

Diet Modification

One way to help address an issue of your fingers smelling like poop is to modify your diet. There are certain dietary changes that you can implement, such as avoiding foods that are high in sulfur content. Foods like cabbage, eggs, garlic and onion have a higher sulfur content, which can cause the pungent smell often associated with poop when broken down in the body.

Other things you can do is limit your consumption of processed foods and unhealthy fats, as well as adding more fiber-rich foods into your diet so that all of your major organs are functioning properly. Additionally, drinking plenty of water will help flush out any potential toxins from within the body. Finally, taking multivitamins and eating a balanced diet full of fresh fruits and vegetables will provide necessary vitamins and minerals which can help keep overall bodily functions optimal.


When treating foul-smelling fingertips syndrome, the focus will be on eliminating the source of the odor. This can be done through hygienic measures, such as washing your hands regularly and keeping them dry, as well as following any dietary changes recommended by your doctor.

In addition, medications may be prescribed to help control or eliminate any underlying conditions that could be causing the odor. Medication could include antibiotics and other treatments for bacterial skin infections or fungal infections that might cause your fingertips to smell.

  • For example, if a bacterial infection is present, your doctor might instruct you to use a topical antibiotic such as mupirocin or chlorhexidine gluconate twice daily after washing your hands with soap and water.
  • Additionally, oral medications such as doxycycline can help treat infections affecting more than just the fingers’ surface area.

In some cases, your fingertips may emit an abnormal odor even if no skin infection is present. If so, antiperspirant creams like aluminum chloride hexahydrate may provide relief from excessive sweat on palms and feet that can contribute to a foul-smelling scent – though when used near sensitive areas on fingers it should only be used under medical supervision as there is potential for skin irritation in those areas.


In conclusion, if your fingers smell like poop, it could be due to a variety of factors. While some causes may require medical attention, most cases can be resolved with lifestyle changes and proper hygiene.

If your fingers still smell bad after trying some of these suggestions, you should consult a doctor or dermatologist to identify the underlying cause of the problem and get further advice on the best course of action.
