There are a few reasons why your breasts may sweat and smell. One is that sweat and oils can accumulate in the breasts due to a variety of factors, such as exercise, heavy sweating, or hormonal changes. Another reason is that the milk ducts in the breasts may become clogged and release sweat and oils, that`s why some women refer their boobs smells like milk or cheese.

Some women may develop hyperhidrosis (excessive sweating) due to other medical conditions, such as anxiety or premenstrual syndrome. If you're concerned about your breast sweat and smell, speak to your doctor or dermatologist for more information.

Under boob sweat is usually most noticeable during the early morning hours, when the body is releasing more hormones. Some women also experience breasts sweat and smell in response to stress or physical exertion.

Causes of Sweat Under Breasts 

The causes can vary from woman to woman but there are some general factors that tend to contribute:


One of the primary causes of breast sweat and smell is the release of hormones. These hormones can be responsible for causing increases in body heat, which then leads to the secretion of sweat from the skin. If you are breastfeeding, these hormones may also lead to an increase in milk production, which can cause a characteristic odor around breasts.


Certain genes are known to play a role in determining how easily a person sweats and smells their own bodily fluids. This means that one's degree of sweating and smelling may be partially hereditary.


Lifestyle choices such as smoking, drinking alcohol, exercising vigorously, or being overweight can all increase the production of sweat and odor.


Climate can also play a role in your ability to sweat and smell. For example, humid conditions can lead to an increase in breast sweat and smell, while dry air may cause sweating to be more severe.


Certain medications can also contribute to breast sweating or odor, including anxiety medication, antidepressant medications such as SSRIs (selective serotonin reuptake inhibitors), birth control pills, anticonvulsants such as seizure drugs lithium carbonate (Lithobid), chemotherapeutic agents used before surgery like methotrexate (MTX) and cisplatin, and hormone replacement therapy. Corticosteroids like prednisone can suppress the production of sebum, which could lead to a decreased ability to sweat and an increase in the production of odor. Also medications for treating thyroid problems like levothyroxine can lead to increased sweating and odor.

Surgery as a Cause of Under Breasts Sweating  

Some surgeries can also cause sweat and odor problems in breast. These include:

 - Breast augmentation: A significant increase in the size of a woman's breasts may cause her to produce more sweat and bacteria.

- Mastectomy: If a woman has undergone a mastectomy, the removal of her breasts may leave behind scar tissue that can block sweat from escaping and result in an increase in the production of smells related to inflammation or infection.

- Weight loss surgery: Surgery that significantly reduces a person's body weight like bariatric surgery can also lead to sweating and an increased likelihood of developing an offensive body odor.

 - Liposuction: Fat cells that are removed during liposuction may release sweat and bacteria.

Do Breast Implants Can Cause More Sweat?

A number of factors can influence whether or not breast implants will cause sweat and odor problems. These factors include:

- The type of implant used: Silicone gel-filled implants are generally less likely to cause sweat and odor problems than saline (water) filled implants, but there is still a chance that they may do so.

- Age: As women age, the production of sebum (sweat) tends to increase, which may lead to an increased likelihood of sweating and odor problems with breast implants.

- Body composition: Women who have more body fat around their breasts are more likely to experience sweat and odor problems with breast implants.

- Genetics: Some women are simply more prone to experiencing sweat and odor problems with breast implants than others.

- Infection: If a woman develops an infection near the implant, this can increase her risk of experiencing sweat and odor problems.

- Pre-existing conditions: Certain health conditions like obesity or diabetes can also lead to increased sweating and the production of odor related hormones. If you are experiencing sweating and odor problems with your breast implants, talk to your doctor about the best ways to manage them.
