Why Do My Boobs Smell?

Yes, it’s normal for your boobs to smell. The cheesy, vinegar-like aroma is the result of bacteria that form in sweat between your breasts.

The odor may be caused by excessive sweating, infection or an underlying medical condition. However, there are several ways to prevent the odor from occurring.

1. Sweating

When sweat isn’t evaporating properly, it can cause a bad smell. The skin under your breasts is prone to this problem because it’s a spot where there is a lot of friction and little air circulation. This is especially true if you have large breasts or boobs that droop due to gravity, which can make it even more difficult for sweat to evaporate.

Your body has two different types of sweat glands. The eccrine glands cover the entire surface of your body and help with temperature regulation. They don’t have the same job as the apocrine glands, which are located in your ears, genitals, armpits and, yes, your boobs. The apocrine glands create a thick, sticky liquid called sebum that gives off an unpleasant odor when it mixes with bacteria.

Sweaty boobs aren’t just uncomfortable, they can also be a sign of some serious health problems. If your boobs are constantly wet or the odor is accompanied by itching, talk to a dermatologist.

2. Bacteria

In warm and humid areas, the skin under breasts stays moist for long time and allows fungi and bacteria to grow in that area. This results in sour smell under the breasts. Women who are diabetic, aging or have excess weight, are at greater risk of such infections under the breasts and hence need to take precautions and follow medical advice in such cases.

The cheesy, fishy or foul odor that won’t go away may be a sign of infection or another condition, especially if it comes with pain or other symptoms such as itching or discharge. A yeast infection called Candida can cause this, and it thrives in warm and moist environments like the folds of the skin under the breasts. Symptoms include a stale beer-like or vinegary odor, a raised rash, and tiny blisters that ooze or crust over.

Hormonal changes throughout a woman’s life, such as during pregnancy or menopause, can also affect the way your boobs smell. These hormone changes are normal, but if you notice an unusual smell that persists, talk to your doctor.

Maintaining good hygiene, wearing breathable fabrics, and changing bras often can help prevent the buildup of sweat or odor-causing bacteria under your breasts. You can also try using calamine lotion, which is known for its anti-fungal properties. Besides, you should always wash your undergarments with antibacterial soap and dry them carefully.

3. Hormones

Hormonal changes in a woman’s body can cause the breasts to smell. These changes can happen due to pregnancy, menstrual cycles or perimenopause.

Basically, hormones are chemical messengers that coordinate and control many different functions in your body. They’re essential for keeping your body healthy and balanced – hormones help to regulate blood sugar levels, water balance, muscle and fat tissue, blood pressure and other bodily systems.

They also communicate with your organs to make them work in tandem with one another. Each hormone has a unique shape, and can only affect the cells of specific tissues that are designed to receive its message. Think of it like a key fitting into a lock – if the hormone’s shape fits the receptor site, then the message is delivered and the action is taken.

Sometimes, a change in hormones can cause the breasts to sweat and smell. This can happen because of a variety of reasons, such as overexertion, heavy sweating or certain medications. These include antidepressants and anxiety medications such as SSRIs (selective serotonin reuptake inhibitors), birth control pills, steroids such as prednisone, chemotherapeutic agents used before surgery like methotrexate and cisplatin and some thyroid medications like levothyroxine. These drugs are known to increase the production of sweat and odor in the cleavage area. In addition, pregnant women may experience a cheesy smell because of the production of colostrum. This is a sign that the body is getting ready to nurse.

4. Food

If the odor coming from your breasts smells like cheesy cheddar, it may be a sign that you are preparing to nurse. The cheesy smell is due to the discharge of colostrum, which is pre-milk. This discharge may be triggered by massage, sexual stimulation, or even by certain foods such as dairy and garlic. This odor can be easily resolved by rubbing a lemon all over your chest area.

It is normal for breasts to have a mild body odor, especially after physical activity or during hormonal changes. However, if the odor is persistent and accompanied by other symptoms, consult with a healthcare professional for personalized guidance. Schedule a consultation today through Nao Medical.
