If a person has body odor like feces even after showering could it be caused by poor diet?

Body odor caused by poor diet is not due to feces. Feces usually do not have a major impact on body odor unless there are specific digestive issues.

Body odor is influenced by a combination of factors, including:

1. Sweat: Sweat itself does not have a smell. However, when bacteria present on your skin break down sweat, they produce certain acids that can cause body odor.

2. Diet: Certain foods, such as garlic, onions, and spices, can cause your sweat to have a stronger odor. This is because some components of these foods are excreted through your skin.

3. Hygiene: Poor hygiene, including infrequent bathing or skipping deodorant, can allow bacteria to build up on your skin and cause body odor.

4. Medical Conditions: Certain medical conditions, such as hormonal imbalances, diabetes, and thyroid disorders, can cause changes in sweat production and body odor.

If you are experiencing persistent body odor that does not improve with good hygiene and a balanced diet, it's important to consult with a healthcare professional to rule out any underlying medical conditions. They can provide an accurate diagnosis and recommend the most appropriate treatment.
