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

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 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
