Dietary Causes of Fishy Body Odor

Dietary Causes of Fishy Body Odor

Have you ever experienced an unpleasant fishy odor coming from your body? Many people might assume that they have poor hygiene but it can happen even if they shower twice a day. This fishy smell can be a sign of an underlying medical condition or it could be related to their diet. Below we will explore how the food we consume can impact our body odor, with a specific emphasis on fish intake and digestive issues.

The Science behind Body Odor

Body odor is a complex issue, influenced by a variety of factors such as hormones, genetics, the presence of bacteria on the skin, and even environmental factors such as heat and humidity. When it comes to diet, the food we eat can impact not only our breath, but the odor that emanates from our skin, feet or other bodily secretions.

Fishy Body Odor

One of the most common causes of fish-like body odor is the intake of fish itself. Fish has uniqe odor compounds such as trimethylamine (TMA), which give fish its characteristic smell. Once consumed, TMA is processed in the liver to become trimethylamine oxide (TMAO), which no longer has the strong odor. However, if TMA is not effectively metabolized by the liver, it can accumulate in the body and be released through the skin and breath, resulting in a fishy odor.

Digestive Issues

Aside from fish intake, digestive issues can also contribute to fishy body odor. When food is not properly broken down in the digestive system, bacteria in the gut can ferment it and produce foul-smelling gases. This is why flatulence can sometimes smell like rotten eggs or spoiled fish. Diabetes, hemorrhoids, and even colon cancer can cause digestive issues, and lead to changes in body odor.

Other Foods that Can Impact Body Odor

While fish is known for its strong odor, other foods can also contribute to body odor. For example, spicy foods can cause us to sweat more, causing a strong, pungent odor. Cruciferous vegetables like broccoli, cauliflower, and cabbage contain sulfurous compounds that can lead to unpleasant body odor. Alcohol and caffeine can increase bacteria in the mouth and cause bad breath, which can also contribute to overall body odor.


If you are experiencing fishy body odor, it’s important to evaluate your diet and see if it could be the cause. Reducing your intake of fish and other odor-causing foods can help minimize body odor. However, if you are concerned that the smell is persistent or worsening, it’s important to consult a medical professional to rule out any underlying medical conditions and receive effective treatment.

Treatment Options

Treatment Options

Having a fishy smell can be a very uncomfortable and embarrassing experience. Fortunately, there are several treatment options that you can try to get rid of this odor. These treatments include antibiotics, probiotics, dietary changes, and hygiene practices. In this article, we will explore each of these options in detail to help you find the best solution to this uncomfortable problem.

1. Antibiotics


If your fishy odor is caused by a bacterial infection, your doctor may prescribe antibiotics to help eliminate the odor. You will need to take the antibiotics as per the recommended dosage and complete the full course of medication. Usually, within a few days of starting the antibiotics, you should start noticing a significant difference in your odor.

2. Probiotics


Probiotics are supplements that contain healthy bacteria that help boost the proper balance of bacteria in your body. They can help decrease the number of harmful bacteria that cause the fishy odor. Probiotics are available in various forms, such as capsules, tablets, or yogurt. It’s recommended to consult a doctor before taking any probiotic supplement, especially if you are pregnant or have other underlying medical conditions.

3. Dietary Changes

Dietary Changes

Your diet plays a significant role in determining your body odor, including fishy smell. Some foods that can cause a fishy smell include spicy and fried foods, red meat, dairy products, caffeine, and alcohol. On the other hand, foods rich in chlorophyll, such as leafy greens, can help neutralize body odor. Make sure to drink plenty of water to help flush toxins out of your body.

4. Hygiene Practices

Hygiene Practices

Poor hygiene practices can lead to a fishy smell. It is essential to maintain proper hygiene practices to eliminate the odor. Take a shower at least once a day, use mild soap to clean your genital area, wear clean and breathable underwear, and avoid using scented feminine products. Make sure to dry yourself properly after bathing to avoid moisture buildup, which can make the odor worse.

5. pH Balance

pH Balance

The pH balance of your body plays a crucial role in reducing body odor, including a fishy smell. Higher pH levels cause an increase in the production of bacteria that cause an unpleasant smell. To lower the pH level, you can bathe with acidic products such as apple cider vinegar or baking soda. You can also increase your intake of foods that have a low pH level, such as citrus fruits and leafy vegetables.

6. Clothing Choices

Clothing Choices

Wearing tight-fitting clothes can trap the odor-causing bacteria, leading to a fishy smell. It is essential to wear loose-fitting clothes to allow proper air flow to your body. Choose clothes made of breathable materials such as cotton to absorb sweat and prevent moisture build-up.

7. Herbal Remedies

Herbal Remedies

Several herbal remedies can help eliminate fishy odor. Some of the most effective herbs include fenugreek, neem leaves, mint, and parsley. You can consume these herbs in various forms, such as capsules, tea, or adding them to your cooking. Herbs are a natural and safe remedy that can help manage the odor without causing any side effects.

In conclusion, getting rid of the fishy smell requires a combination of different treatment options. These options include antibiotics, probiotics, dietary changes, hygiene practices, pH balance, clothing choices, and herbal remedies. By trying out these treatments, you will be able to effectively eliminate the odor and regain your confidence.

Preventative Measures

When you smell like fish, it can be a source of embarrassment and concern. This unpleasant odor can linger and be noticeable to those around you, causing discomfort and even social isolation. However, there are several things you can do to prevent fishy body odor from occurring or worsening.

  1. Maintain good hygiene: One of the most effective ways to prevent fishy body odor is to maintain good hygiene practices. This means taking regular showers or baths with soap and water, paying attention to your armpits and groin area, and washing your clothes frequently. Bacteria and sweat are a common cause of body odor, so regularly cleaning your body and clothing can help reduce odor.
  2. Avoid certain foods: Certain foods, such as spicy or pungent cuisine, can cause body odor to become stronger or more noticeable. Avoiding these types of foods or reducing your intake can help prevent fishy body odor from occurring. Additionally, choosing foods rich in zinc and magnesium can help reduce body odor, as these minerals are important for regulating sweat production and eliminating toxins.
  3. Drink plenty of water: Staying hydrated is important for overall health, but it can also help prevent body odor. Drinking water helps flush toxins from the body, reducing the likelihood of odor-causing bacteria accumulating on the skin or in sweat.
  4. Wear breathable clothing: Wearing tight or synthetic clothing can trap sweat and bacteria against the skin, leading to stronger body odor. Choosing loose, breathable fabrics like cotton or linen can help reduce odor by allowing air to circulate around the body and keeping sweat at bay.
  5. Use deodorant or antiperspirant: Deodorant and antiperspirant are designed to prevent body odor and sweating, respectively. Choosing a product that works for your body and applying it regularly can help keep fishy body odor at bay. Some people may need to apply deodorant or antiperspirant more frequently than others, depending on their level of sweat production or activity level.
  6. Manage stress: Stress can cause the body to produce more sweat and odor-causing bacteria, so finding ways to manage stress can help prevent fishy body odor. This can include activities like yoga, meditation, or taking a relaxing bath.
  7. Seek medical attention: If you have persistent or particularly strong fishy body odor, it may be a sign of an underlying medical condition. Conditions like trimethylaminuria, or fish odor syndrome, can cause a strong odor that is difficult to manage with typical hygiene practices. Seeing a doctor or dermatologist can help diagnose any underlying conditions and provide treatment options to manage body odor.
  8. Try natural remedies: Natural remedies like tea tree oil, witch hazel, or baking soda can help reduce body odor by killing bacteria or neutralizing odor. These remedies may not work for everyone, but they can be a cost-effective and natural alternative to traditional deodorant or antiperspirant.

Overall, preventing fishy body odor requires a combination of good hygiene practices, dietary choices, and lifestyle changes. By following these tips and seeking medical attention when necessary, you can manage body odor and feel confident in your own skin.



With all the possible causes of smelling like fish, it is crucial to figure out what is causing the odor. In some instances, the smell may be mild and go away with proper hygiene practices. However, if the odor persists, it is advisable to seek medical attention as it could be a sign of an underlying medical condition.

It’s essential to note that personal hygiene plays a crucial role in maintaining a fresh and clean scent. Sometimes, the lack of proper hygiene practices can cause an unpleasant smell, which can be quickly rectified with regular washing and wearing clean clothes.

However, if maintaining good hygiene practices does not work, then it may be time to look for other causes such as an infection, disease, or medication. A professional medical diagnosis will help determine the right course of action.

The first step to getting treatment is to consult a physician who will ask some questions to determine the possible cause of the smell. In some scenarios, a specialist may be needed, such as an endocrinologist or gynecologist, based on the cause of the odor. Depending on the diagnosis, a doctor may prescribe medication, perform a surgery or suggest lifestyle changes to help alleviate the scent.

Lastly, it is crucial to remember that smelling like fish can cause severe emotional distress to an individual. It can lead to self-esteem issues, anxiety, and even depression. Hence, seeking medical attention not only helps deal with the physical symptoms but also helps deal with the emotional stress that comes with the condition.

The bottom line is that smelling like fish is not normal and should not be ignored. It is a sign that something is not right. Seeking medical attention is the right step towards resolving the issue. It is crucial not to self-diagnose or ignore the problem as it can lead to further health complications.

It is commendable to seek help as early as possible. Most medical conditions that cause fishy smell can be treated if detected early. Delaying medical intervention can result in more severe complications that may be harder and costlier to treat.

Ultimately, it is in everyone’s best interest to take proper care of their hygiene and seek medical attention when experiencing an unusual scent that persists, especially if it smells like fish.
