Why does my sweat smell like sour vinegar? I sweat a lot during the night, but i never use too. Should i be worried?

Many possibilities.: Sweat can smell like whatever you have been eating. Some vitamins and medications can do it too. Or if you have diabetes, that can do it. Certain types of bacteria can also break down sweat into proprionic acid, which has a similar structure to acetic acid (the acid found in vinegar). If dietary change and stopping/changing medications doesn't solve the problem, see your doctor. ...Read more

My sweat smells like vinegar when I wake up after sweating during night. Is it anything serious?

Vinegar swell: Most likely it i just your sweat. A light sweat can have sort of a vinegary, mild acid odor. After the time it gets stringer, starts smelly fishy, then gets really foul. Make sure you wipe you sweat off after all exercise. Some people just sweat at night (colds, medications, certain diseases, over-bundled). Wipe it off, use a deodorizer, and see if it comes back. It does not sound like a disease. ...Read more

More detail needed..: There are so many variables... what is the air temp of yoursleeping area, what type of bed covers, what is your diet, what is your BMI, what other medicines, what other health issues? The odor could be the result of skin bacteria working on sweat chemicals. Sweatting is also a way the body can rid itself of toxins, hence the value of sauna therapy for detoxification. Consult with a Endocrinologist ...Read more

Fermentation: The only time I have seen this happening is if you have fungal infection in your body. Certain fungus ferments the sweat or other body fluids. Seek MD help. ...Read more

My 2yr old daughter's sweat smells like vinegar and she sweats a lot, even out of the bath, should I have her tested?

Consult a specialist: There are a number of metabolic disorders that cause unusual body odors. Some of them can be treated by a change in the diet alone. I would recommend having your child seen by a geneticist who specializes in these rare conditions to see if further work-up is warranted. ...Read more

My body odor smells like vinegar am i acidic?

My body odor smells like vinegar am i acidic?

Not 'acidic': 'pop' claims about 'acid' and 'alkaline' body types are totally made up. Certain bacteria that some people have degrade certain products in your sweat to certain short-chain fatty acids that have a vinegar smell. Shower a few times a day and this will probably help. ...Read more
