What is Mastitis? It’s Causes, Symptoms, Diagnosis, Prevention and Treatment

A mother’s love is often seen as one of the purest emotions, and breastfeeding is believed to reflect that deep connection. However, this journey is not always as easy as it is portrayed. Many new mothers struggle with pain and inflammation during breastfeeding, and one common condition behind this discomfort is mastitis.

If you are a new mother experiencing these challenges, this blog is for you. Here, we will help you understand what mastitis is, its symptoms, and what you can do if your symptoms match those of mastitis.

What is Mastitis?

Mastitis is a condition that causes inflammation in the breast tissue. It may or may not involve any infection. It mainly affects breastfeeding women and is also called ‘lactational mastitis’.

The reason mastitis occurs is usually due to buildup of milk in the breast or when bacteria enter through cracked skin, leading to infection. Though it is very rare, it can also occur in those who are not breastfeeding.

What are the Signs of Mastitis?

A breastfeeding parent may experience the following common symptoms of mastitis:

• Breast pain or tenderness
• Swelling in the breast
• A red, wedge-shaped area on the breast
• Fever and chills
• Fatigue or a general feeling of being unwell
• Headache or body aches

Initially, you may feel like having a clogged duct with slight pain, heaviness, or small lumps. But if the symptoms worsen quickly, it may indicate a mastitis infection rather than just a blockage. If you notice any of these symptoms, consult a gynaecologist as early as possible. Early detection can help you prevent the condition from worsening.

Why Does Mastiti Occur?

As mentioned earlier, the breasts are made of milk-producing glands and small tube-like ducts that carry milk from the glands to the nipple. Any abnormality in this process can lead to mastitis.

Let’s understand some of the common causes of mastitis.

• Blocked milk ducts: In this case, the milk is not fully drained, which causes mastitis inflammation.
• Bacterial entry: If your nipples are sore or cracked, they can allow the mastitis bacteria (staphylococcus aureus) to enter the breast.
• Irregular feeding patterns: If a mother misses breastfeeding sessions (skipping feeds) or if the baby is not properly attached to the breast (poor latch), milk may not be fully removed from the breast which can cause mastitis.

The World Health Organisation (WHO) says that proper breastfeeding techniques and frequent feeding play a very important role in preventing mastitis from breastfeeding.

What are the risk factors for mastitis?

There are certain situations that may increase the chances of developing mastitis:

• Poor breastfeeding latch, where the baby’s mouth is not properly attached to the breast and milk may not drain completely
• Engorgement, where overfull breasts puts pressure and may cause milk to leak into surrounding breast tissue, leading to inflammation and bacterial growth
• Cracked or sore nipples, which can let bacteria to enter the breast
• Tight clothing or pressure on breasts, which can restrict milk flow
• Previous episodes of mastitis
• Stress and fatigue

Having one or more risk factors does not mean you will definitely develop mastitis, but being aware can help you prevent it. If you are unsure, it is a good idea to speak with an obstetrician-gynecologist to identify the condition early and take the right steps.

How is Mastitis Diagnosed?

Doctors usually diagnose mastitis based on your symptoms and a physical examination.

You may be asked about:

• Your breastfeeding patterns
• When you first noticed the symptoms
• Any fever or pain

In some cases, especially if symptoms don’t improve, a milk sample test, mammography or an ultrasound may be done to rule out an abscess (a pus-filled infection), breast cancer, or other conditions.

What is the Most Effective Way to Treat Mastitis?

There is no one best treatment for mastitis. The right approach to treatment depends on how severe it is. Generally, the treatment focuses mainly on reducing pain and inflammation and preventing infection.

According to a document published by the World Health Organisation, the main principles of mastitis treatment are:

• Supportive counselling
• Effective milk removal
• Antibiotic therapy
• Symptomatic treatment

It is important to know that researchers are constantly working to find better ways to treat this condition. Therefore, it is important to talk to your obstetrician-gynecologist to better understand your condition.

The Academy of Breastfeeding Medicine (2022) guidelines warn against aggressive massage and attempts to empty the breast completely, as mastitis is not just a blocked duct but it also involves ductal narrowing and inflammation.

Earlier treatment practices included heat, massage, and extra pumping, whereas the modern approaches focus on anti-inflammatory care.

If the condition is mild, the following remedies may help you feel better:

• Cold compresses for 10 to 15 minutes at a time
• Anti-inflammatory medicines (as prescribed by your doctor)
• Continue breastfeeding with a good latch and positioning
• Light, gentle touch or patting if needed
• Wear comfortable clothes
• Stay well hydrated

What You Should Not Do

• Aggressive massage can injure the breast tissue and increase inflammation
• Avoid pumping excessively to try to clear it
• Tight bras or pressure on the breast can worsen blockage

FAQs

What side effects might mastitis cause?

Mastitis can cause inflammation, fatigue, fever, breast pain, swelling, and redness. In rare cases, it may lead to an abscess if untreated.

What is the duration of mastitis?

With proper mastitis treatment, symptoms usually improve within 2 to 3 days, though full recovery may take up to a week.

Is it safe to continue nursing when you have mastitis?

Yes. It is safe to continue breastfeeding if you have mastitis. Continuing to nurse helps keep the milk flowing, which can clear blocked ducts and reduce inflammation. Regular breastfeeding with the right techniques also improves healing and prevents the condition from worsening, while still being safe for your baby.

Can I get mastitis more than once?

Yes. Mastitis can occur more than once, especially if the underlying causes are not resolved. Factors like poor latch, skipped feeds, or incomplete emptying of the breast can increase the risk of recurrence. Taking steps such as ensuring proper breastfeeding technique and regular feeding can help reduce the chances of mastitis happening again.

What can I anticipate if I get mastitis?

If you develop mastitis, you may experience breast pain, inflammation, swelling, and redness, along with flu-like symptoms such as fever, chills, and fatigue. The affected area of the breast may feel tender, making breastfeeding uncomfortable. But with early care, recovery is usually quick.

Does having mastitis make you more susceptible to breast cancer?

No. Mastitis does not increase the risk of breast cancer. However, persistent symptoms should always be evaluated by a doctor to rule out other conditions.
