Body odor is caused by a mix of bacteria and sweat on your skin. Sweat itself doesn’t smell, but when the bacteria on your skin mix with sweat, the water, salt, and fat can cause odor. The odor can be bad, good, or have no smell at all. Factors like the foods you eat, hormones, or medications can affect body odor. A condition called hyperhidrosis makes a person sweat excessively. If you have diabetes, a change in body odor could be a sign of diabetes-related ketoacidosis. High ketone levels cause your blood to become acidic and your body odor to be fruity. In the case of liver or kidney disease, your odor may give off a bleach-like smell due to toxin buildup in your body. Some foods can change the way you smell, such as cruciferous vegetables like broccoli, cabbage, and cauliflower, which produce gas, and garlic and onions, which release sulfur-like compounds that waft out through your pores. Drinks with caffeine or alcohol may also make you sweat more. Body odor is caused by bacteria breaking down the sweat from the apocrine glands in your armpits, groin, and pubic area. To reduce body odor, it is recommended to shower at least once a day, use antibacterial soap, and wash workout clothes often. Additionally, changing your diet and talking to a doctor or dietitian before making drastic changes to your diet can help.
