Body odor is a natural part of being human. It is caused by the breakdown of sweat by bacteria on the skin. However, excessive body odor can be a sign of an underlying health condition.


There are many reasons why body odor can be a health concern. In some cases, it can be a sign of a serious illness, such as liver disease, kidney disease, or diabetes. In other cases, it may be a sign of a less serious condition, such as a bacterial infection or a fungal infection.


If you notice a sudden change in your body odor, or if your body odor is particularly strong, it is important to see a doctor to rule out any underlying health conditions.

Here are 7 reasons body odor can be a health concern:


1. Diabetes

People with diabetes often have a sweet or fruity body odor. This is because their bodies are not able to properly metabolize glucose, which leads to a buildup of sugar in the blood. This sugar can be excreted in sweat, which attracts bacteria.

2. Liver disease

People with liver disease often have a fishy or musty body odor. This is because the liver is responsible for removing toxins from the blood. When the liver is not functioning properly, these toxins can build up in the body and be excreted in sweat.

3. Kidney disease

People with kidney disease often have a urine-like body odor. This is because the kidneys are responsible for filtering waste products from the blood. When the kidneys are not functioning properly, these waste products can build up in the body and be excreted in sweat.

4. Thyroid disease

People with thyroid disease often have a metallic or sour body odor. This is because the thyroid gland produces hormones that regulate metabolism. When the thyroid gland is not functioning properly, metabolism can be affected, which can lead to changes in body odor.

5. Infections

Bacterial and fungal infections can also cause changes in body odor. For example, people with a yeast infection may have a sweet or sour body odor. People with a bacterial infection may have a foul-smelling body odor.

6. Certain medications

Some medications can also cause changes in body odor. For example, some antibiotics can cause a metallic taste in the mouth and a foul-smelling body odor.

7. Diet

What you eat can also affect your body odor. For example, eating strong-smelling foods, such as garlic and onions, can cause your body odor to be stronger.

When to see a doctor

If you notice a sudden change in your body odor, or if your body odor is particularly strong, it is important to see a doctor to rule out any underlying health conditions.

How to reduce body odor

There are a number of things you can do to reduce body odor, including:

  • Shower or bathe daily.
  • Use soap to wash your armpits, groin, and feet thoroughly.
  • Apply antiperspirant or deodorant to your armpits.
  • Wear loose-fitting, breathable clothing.
  • Avoid eating strong-smelling foods.

If you have a medical condition that is causing your body odor, your doctor may recommend additional treatments, such as medication or surgery.

Body odor is a normal part of being human. However, excessive body odor can be a sign of an underlying health condition. If you notice a sudden change in your body odor, or if your body odor is particularly strong, it is important to see a doctor to rule out any underlying health conditions.

Here are some additional tips for reducing body odor:

  • Avoid wearing synthetic fabrics, as they can trap sweat and bacteria.
  • Drink plenty of fluids to stay hydrated.
  • Manage stress levels, as stress can trigger sweating.
  • Eat a healthy diet and get regular exercise.

If you have any concerns about your body odor, please talk to your doctor.
