Sweating is a natural process that helps regulate body temperature and expel toxins. We all sweat, and the smell that goes along with it is completely normal. This will of course not come as a surprise to you, if you’ve ever been to a gym locker, or have taken public transport on a hot summer day. Sweat has a bit of a distinct smell, that is commonly expected. So far, so good.

You are probably reading this as you are experiencing a change in the smell of your sweat. This change in the smell of your sweat is quite common, and one of the more unpleasant is a vinegar-like odor. If you’ve noticed this problem, you’re probably wondering what’s causing it and how to get rid of it. In this article, we’ll explore the most common reasons why your sweat smells like vinegar and offer some solutions to help you deal with this issue.

What Causes Vinegar-Like Sweat?

1. Bacteria

Bacteria are a common cause of body odor, and vinegar-like sweat is no exception. The human body hosts millions of bacteria, many of which are harmless, but others can produce unpleasant smells. When bacteria break down sweat on your skin, they release volatile organic compounds (VOCs) that can smell like vinegar. This can be particularly problematic in areas of the body that are prone to sweating, such as the armpits, groin, and feet.

2. Diet

Your diet can also play a role in the way your sweat smells. Some foods, such as garlic and onions, contain sulfur compounds that can be released through your pores when you sweat. These compounds can give your sweat a pungent, vinegar-like odor. Similarly, consuming a lot of acidic foods, such as citrus fruits and vinegar, can alter the pH of your sweat, making it more acidic and vinegar-like.

Another possible cause of vinegar smelling sweat is the keto diet. The keto diet is a low-carb, high-fat diet that is designed to put your body in a state of ketosis. When your body is in ketosis, it produces ketones, which are acidic compounds that can cause your sweat to smell like vinegar.

3. Medical Conditions

In some cases, vinegar-like sweat can be a symptom of an underlying medical condition. For example, people with diabetes may experience a sweet, fruity odor in their sweat due to high levels of glucose in their blood. Similarly, people with liver or kidney problems may have a musty or vinegar-like odor in their sweat due to a buildup of toxins in their body.

4. Menopause

Menopause is another possible cause of vinegar smelling sweat. During menopause, the body undergoes significant hormonal changes, which can cause changes in body odor. Menopausal women may experience hot flashes and night sweats, which can cause excessive sweating and a vinegar-like odor.

How to Get Rid of Vinegar-Like Sweat

1. Practice Good Hygiene

The most effective way to get rid of vinegar-like sweat is to practice good hygiene. This means showering regularly, especially after exercise or other activities that cause you to sweat. Use soap and water to wash your body thoroughly, paying particular attention to areas that are prone to sweating, such as your armpits and groin. You may also want to consider using an antiperspirant or deodorant to help control sweat and odor.

2. Change Your Diet

If your sweat smells like vinegar due to your diet, you may be able to eliminate the problem by making some changes to what you eat. Try reducing your intake of sulfur-containing foods, such as garlic and onions, and acidic foods, such as vinegar and citrus fruits. Instead, focus on eating a healthy, balanced diet that includes plenty of fruits, vegetables, and lean protein.

3. See a Doctor

If you’ve tried practicing good hygiene and changing your diet but still have vinegar-like sweat, it may be a good idea to see a doctor. They can perform tests to determine if there’s an underlying medical condition that’s causing your symptoms. If so, they can recommend appropriate treatment options to help alleviate the problem.

Other Ways to Manage Sweat That Smells Like Vinegar

1. Wear Breathable Clothing

Wearing breathable clothing can help prevent excessive sweating and reduce the risk of bacterial and yeast overgrowth. Choose clothing made from natural fibers, such as cotton or linen, which are more breathable and allow air to circulate around the body. Avoid tight-fitting clothing, which can trap sweat against the skin and promote bacterial and yeast growth.

2. Use Antiperspirants and Deodorants

Antiperspirants and deodorants can help reduce sweating and control body odor. Antiperspirants work by blocking sweat glands, while deodorants mask the smell of sweat. Look for products that contain aluminum chloride or zinc oxide, which are effective at controlling sweat and odor.

3. Stay Hydrated

Drinking plenty of water can help dilute the acidity of sweat and reduce the risk of bacterial and yeast overgrowth. Aim to drink at least eight glasses of water a day, and avoid sugary or caffeinated beverages, which can dehydrate the body and increase the risk of vinegar smelling sweat.


Vinegar-like sweat can be an embarrassing and unpleasant problem, but it’s not uncommon. Fortunately, there are steps you can take to get rid of this problem. By practicing good hygiene, changing your diet, and seeing a doctor if necessary, you can eliminate vinegar-like sweat and enjoy fresher, more pleasant-smelling skin. Remember that everyone’s body is different, and what works for one person may not work for another, so be patient and persistent in your efforts and you will soon be able to get rid of this problem.
