Mastitis (breast inflammation) that can occur during breastfeeding: Medical solutions 🤱🤒

Madusha (age 29), a mother of a 3-week-old baby, came to my clinic last Tuesday. She was shivering profusely, had a high fever, and was feeling tired.

"Dr. Priya, I've been feeling very cold and feverish since last night. My whole body aches, like I have the flu. One side of my right breast is red, swollen, and painful to the touch. I'm afraid my milk will pass germs to the baby, so I've stopped breastfeeding," Madusha explained her illness.

I examined her and explained: "Madusha, you are facing a condition known as mastitis in medical science. This is an inflammation or infection of the breast tissue, and it is not an infection of the milk at all. Therefore, your breast milk is completely safe for your baby. In fact, continuing to breastfeed is essential for mastitis to heal, and if you stop breastfeeding, there is a risk of milk accumulating in the breast and forming a breast abscess . This is caused by a blocked milk duct or a cracked nipple, allowing bacteria to enter. Today, let's see how to diagnose mastitis and what are the medical treatments for it."

🚨 Red Flags that require immediate medical attention

Mastitis usually begins to heal within 48 hours with proper medical care. However, you should see a doctor immediately if you have any of the following warning signs:

  • Fever or breast pain that does not subside after 24-48 hours of taking antibiotics.
  • A hard lump in the breast gradually becomes soft, feels fluid-filled, and is very painful (this is a sign of a developing breast abscess).
  • Redness in the breast that quickly spreads to the chest or armpit.
  • The mother may have extreme cold and shivering, fainting, or difficulty breathing (sepsis - signs of the germs spreading to the bloodstream).
❓ FAQ

FAQ

Evidence-based clinical answers to common patient questions

Is breastfeeding harmful to the baby when there is mastitis?

No. Bacterial infections in the breast will not affect your milk. Breastfeeding is completely safe because the antibodies in the milk protect the baby from those germs.

How to diagnose a breast abscess?

If mastitis is not treated properly, pus can collect in the breast and form a lump. This is extremely painful and feels soft and fluid-filled when touched. This can be accurately diagnosed with a breast ultrasound test.

Why does severe breast inflammation occur after using antibiotics?

Candida yeast infection can occur when the beneficial bacteria in the body are destroyed due to taking antibiotics. In this case, a severe burning or stabbing pain is felt in the breast during and after breastfeeding. For this, antifungal treatment should be taken on the advice of a doctor.

Is there a link between mastitis and breast cancer?

No. Mastitis is a temporary infection and does not cause breast cancer. However, if a lump or change in the breast does not completely heal after a month of treatment, you should see a doctor to make sure there are no other medical conditions.
