Mastitis in Breastfeeding Mothers: An Explainer

by admin-blog-kh | June 16, 2026 11:04 am

Summary

Mastitis is a common condition in breastfeeding mothers in which breast tissue becomes inflamed, causing pain, swelling, redness, and warmth. It often affects one breast and may be accompanied by fever, chills, fatigue, and flu-like symptoms.

Mastitis usually occurs in the first three months of breastfeeding and is often caused by a build-up of milk, known as engorgement, due to oversupply or infrequent feeding. If left untreated, the inflammation can sometimes lead to bacterial infection or abscess formation.

Early diagnosis, usually through a physical examination, is important. Treatment includes rest, cold compresses, pain relief, and continued breastfeeding. Antibiotics may be required if an infection develops. Preventive measures include frequent feeding, proper latching, and avoiding tight clothing.

What is Mastitis? 

Breastfeeding is an important part of caring for a newborn, providing ideal nutrition and supporting bonding between mother and baby[1]. However, it can also be physically demanding, especially in the early months.

Mastitis is a condition in which the breast tissue becomes inflamed, leading to swelling, redness, and pain. The affected area may feel warm to the touch. According to gynaecologists, some mothers may also experience flu-like symptoms such as fever, body aches, and fatigue.

If left untreated, mastitis can progress to a bacterial infection and may lead to a breast abscess. It is most commonly seen during the first three months of breastfeeding.

Symptoms of Mastitis 

Mastitis usually affects one breast at a time, although both breasts can occasionally be involved. Symptoms often develop quickly and may include:

What Causes Mastitis?  

Mastitis is most often caused by a build-up of milk in the breast, which occurs when milk is produced faster than it is removed. This may happen due to infrequent feeding, incomplete emptying of the breast, or oversupply, also known as hyperlactation.

When milk accumulates, it can put pressure on the surrounding tissue, leading to swelling, known as engorgement, and narrowing of the milk ducts. This results in inflammatory mastitis.

Inflamed breast tissue is more vulnerable to infection. Bacteria from the skin or the baby’s mouth can enter the milk ducts, leading to bacterial mastitis.

How is Mastitis Diagnosed? 

If you experience breast pain, swelling, or redness, it is important to consult your gynaecologist promptly.[3]

Diagnosis is usually based on a clinical assessment, including a physical examination and a review of symptoms. In most cases, no additional tests are required. However, if symptoms are severe, recurrent, or occur in non-breastfeeding women, further investigations may be recommended.

Mastitis Treatment 

Mastitis is generally treatable, especially when identified early. Treatment focuses on reducing inflammation, relieving pain, and addressing any underlying infection.

Applying cold compresses to the affected area can help reduce swelling and discomfort. It is advisable to rest and stay well hydrated. Pain relief medication may be prescribed if needed.

Unlike some other breast conditions, the swelling in mastitis is due to inflammation rather than a simple blockage. Therefore, vigorous massage is not recommended, as it may worsen the condition. Gentle, guided lymphatic drainage techniques may be helpful in some cases.

If a bacterial infection is present, antibiotics may be prescribed. Mothers can usually continue breastfeeding safely while on treatment. In fact, regular breastfeeding is encouraged, as it helps keep milk flowing and prevents further build-up. Avoid excessive pumping, as this may increase milk production and worsen engorgement.

Inflammatory mastitis typically begins to improve within 48 to 72 hours of treatment, with full recovery expected within about 7 to 10 days.

Preventing Mastitis 

Although mastitis is common, certain practices can help reduce the risk:

Frequent feeding
Feed your baby regularly and avoid long gaps between feeds. This helps prevent milk from accumulating in the breasts. Alternate between breasts to ensure both are emptied effectively.

Correct latching
Ensure that your baby is latching properly during feeds. A good latch allows efficient milk removal and reduces the risk of engorgement. If needed, seek guidance from a lactation consultant.

Avoid tight bras
Wear a supportive but well-fitted bra that does not compress the breasts. Tight clothing can restrict milk flow and increase the risk of mastitis.

Frequently Asked Questions 

What is mastitis and how common is it during breastfeeding?

Mastitis is an inflammation of breast tissue that causes pain, swelling, redness, and warmth in the breast. It is a common breastfeeding-related condition, particularly during the first few months after childbirth.

What are the early signs of mastitis?

Early symptoms include breast tenderness, swelling, redness, warmth, and pain during feeding. Some mothers may also experience fever, chills, fatigue, and flu-like symptoms as the condition progresses.

Can I continue breastfeeding if I have mastitis?

Yes. Continuing to breastfeed is usually recommended because it helps remove milk from the breast and may support recovery. Most mothers can safely continue breastfeeding even if antibiotics are prescribed.

What causes mastitis in breastfeeding mothers?

Mastitis often develops when milk is not removed effectively from the breast, leading to engorgement and inflammation. In some cases, bacteria can enter the breast tissue through cracked nipples or milk ducts, causing infection.

How long does mastitis take to heal?

Many mothers start feeling better within 48 to 72 hours of starting treatment. Complete recovery typically occurs within 7 to 10 days, although severe infections may take longer and require closer medical follow-up.

How can mastitis be prevented?

Regular breastfeeding, proper latching, avoiding long gaps between feeds, wearing comfortable bras, and seeking early help for breast discomfort can reduce the risk of mastitis. Good breastfeeding techniques are key to prevention.

When should I see a doctor for mastitis?

Seek medical attention if you have persistent breast pain, worsening redness, high fever, symptoms that do not improve within 24 to 48 hours, or signs of a breast abscess such as a painful lump with increasing swelling.
