Body odors are a natural manifestation of the human body. However, when these smells become unusual or intense, they can be warning signs that the body emits to warn us that something is not right. Although often attributed to poor hygiene, certain lingering or specific odors may be linked to underlying health issues. Below, we explore five body odors that could indicate a health risk that you shouldn’t ignore.

1. Fruity smell on the breath

Sweet-smelling or fruity breath may seem harmless, but in some cases it’s a sign of diabetic ketoacidosis, a serious complication of diabetes. This occurs when the body, unable to use glucose properly, begins to break down fats, producing ketones that are eliminated by breathing. If this odor is accompanied by excessive thirst, fatigue, or confusion, it is urgent to seek medical attention.

2. Bad odor on the feet

Strong foot odor is not always caused by sweat. If the odor is particularly pungent or persistent, it could be due to fungal infections such as athlete’s foot. In more severe cases, it can also be associated with circulation problems or diabetic neuropathy. Humidity and prolonged use of closed shoes can aggravate the situation.

3. Fish-like body odor

This characteristic odor may be related to a rare metabolic disorder called fishy odor syndrome or trimethylaminuria. In this case, the body does not properly break down trimethylamine, a substance that is released through sweat, urine, and breathing. Although it is a rare genetic condition, it can significantly affect quality of life and requires specialized medical attention.

4. Ammonia smell in sweat

An ammonia-like odor can appear in people who exercise intensely without consuming enough carbohydrates. However, if the odor persists even at rest, it could be related to liver or kidney problems, since the body would be eliminating nitrogenous waste through sweat, due to a malfunction of these organs.

5. Sour or acidic body odor

A very acidic or sour body odor can be due to hormonal disturbances, extreme stress, or disorders of the digestive system. It can also occur in people with thyroid problems or nutritional deficiencies. If this smell appears suddenly and does not improve with hygiene, it is advisable to have a medical evaluation.

What to do if you notice a change in your body odor?

Paying attention to changes in body odor can help you identify a medical condition early. While many factors can influence body odors (food, medications, environment), if an unusual odor persists for several days or occurs along with other symptoms, don’t ignore it.
