Mastitis: Painful Breast Tissue Inflammation – Symptoms and Management Tips

25 Feb 2025

Mastitis is an inflammation of breast tissue, often caused by a bacterial infection or a blockage of the milk ducts. In breastfeeding women, the incidence of mastitis is between 3% and 20% in the first 6 months after childbirth. The risk of this condition is higher when the mother does not breastfeed frequently or does not produce enough milk. Although more common during breastfeeding, mastitis can also occur due to hormonal imbalances or menopause. Constant pain and specific inflammation can cause continuous discomfort.

Even though specific treatments are available to help alleviate symptoms, prevention remains the best solution. A balanced lifestyle and proper hygiene are essential for preventing mastitis and for breast health. Learn more about mastitis by reading this article!

Mastitis – Symptoms, Causes, and Prevention

Mastitis is an inflammation of the breast that often occurs during breastfeeding but can also affect women who are not breastfeeding. If not treated properly, acute mastitis can lead to a breast abscess, which occurs in approximately 3-11% of cases and may require specialized medical treatment. Therefore, to prevent complications, it is essential that mastitis is diagnosed and treated promptly.

What is mastitis and how can it affect women?

Mastitis is an inflammation of breast tissue that can occur when bacteria enter the mammary glands through cracks or lesions on the nipple. When this happens, bacteria can multiply and cause an infection that leads to inflammation of the breast tissue. This manifests as pain, redness, swelling, and often fever. Mastitis can also lead to the formation of a breast abscess.

Research suggests that certain probiotic strains may reduce the risk or severity of mastitis in breastfeeding women. These probiotics work by modulating the immune response and preventing the development of pathogenic bacteria that cause infections.

Mastitis – Classification

Mastitis can be classified into several types, but lactational mastitis is the most common. Other forms may be rarer and are often associated with other medical conditions.

Thus, the most common types of mastitis include:

Acute or Lactational Mastitis is the most frequent form and occurs when bacteria enter breast tissue during breastfeeding. This can be caused by a blockage of the milk ducts or irregular breastfeeding. After weaning, lactational mastitis can still occur, although it is less common. In this case, the condition can be caused by residual milk stagnation in the mammary glands, especially if the weaning process was not gradual.
Non-lactational Mastitis is not associated with breastfeeding and can occur due to hormonal conditions, such as gynecomastia or breast infections.
Chronic Mastitis is a rare and persistent form of mastitis, which can be caused by repeated inflammation or a long-term infection.

How can mastitis affect mothers’ lives?

Constant pain and inflammation in the breasts can make breastfeeding difficult, creating a continuous feeling of discomfort. Additionally, symptoms such as fever and fatigue can lead to decreased energy and a general feeling of malaise. These physical problems, along with the challenges of caring for a newborn, can increase stress levels and irritability. Furthermore, when not treated properly, mastitis can lead to a breast abscess, a complication of the disease.

Mastitis Symptoms – What are they and why do they occur?

Mastitis can cause significant pain and discomfort, and in severe cases, it can lead to complications. Understanding the symptoms and causes of mastitis is essential for quick identification of the condition and application of appropriate treatment.

How does mastitis manifest? Symptoms can range from mild to severe and may include:

Breast Pain is one of the most common symptoms. It can appear suddenly and be localized to a specific area of the breast. In severe cases, the pain can become constant and intense.
Breast Swelling – the affected area of the breast may become swollen, tender to the touch, and warmer than the rest of the breast. This symptom can affect a large area or just a part of the breast.
Reddened Skin – the skin on the inflamed breast may become red or have a darker hue. As a sign of acute inflammation, redness is often accompanied by a feeling of warmth in the affected area.
Fever – in many cases, mastitis causes a fever, which can be mild or moderate. Fever is the body’s response to infection and inflammation.
Chills and Generalized Malaise – in more severe cases of mastitis, women may experience chills, fatigue, or a general feeling of unwellness.
Fainting or Nausea – these symptoms can occur in some women, especially if the infection becomes severe or if the fever is very high.
Nipple Discharge – in cases of mastitis caused by bacterial infections, discharge from the nipple may occur, which can be yellowish-green or have an unpleasant odor. Such discharge is a clear sign of infection.

What are the causes of mastitis?

The main cause of mastitis is bacterial infection, particularly with *Staphylococcus aureus*, which can penetrate breast tissue through blocked milk ducts. This can occur when milk is not efficiently removed.

Here are some possible causes that can lead to mastitis:

Blocked Milk Ducts – when milk is not properly drained, it can remain trapped in the milk ducts, causing inflammation of breast tissue.
Bacterial Infections – bacteria can enter the breast through cracks or wounds on the nipple, triggering an infection.
Irregular Breastfeeding – intervals that are too long between feedings or the baby not sucking effectively can increase the risk of mastitis.
Gynecomastia, which manifests as abnormal growth of breast tissue. The condition is specific to women who are not breastfeeding and is caused by hormonal fluctuations.
Irritation Caused by Hygiene Products – some creams or hygiene products can irritate the sensitive skin of the breasts, promoting the onset of infections.
Nipple Irritation or Trauma – friction caused by using an inappropriate breastfeeding device can cause nipple lesions. These lesions allow bacteria to penetrate the breast more easily and cause infection.
Weakened Immune System – women with compromised immune systems or pre-existing conditions such as diabetes or autoimmune diseases are more susceptible to developing mastitis. A weakened immune system can make it difficult for the body to fight off infections and inflammation.

Mastitis in Breastfeeding – How to Manage it Correctly?

To prevent mastitis, it is important for the mother to breastfeed frequently and ensure the baby is positioned correctly at the breast. Breast hygiene must be appropriate, and avoiding milk stasis is crucial. If infection is present, antibiotics may be recommended, as well as measures such as regular breastfeeding and massage of the affected breast.

Here are some effective tips for managing breast mastitis during breastfeeding:

Ensure the baby is breastfeeding effectively and there is no stagnant milk.
Use warm or cold compresses on the affected area. These help reduce inflammation associated with mastitis and stimulate milk flow.
Rest and hydrate properly – recovery also depends on the mother’s general health.
Gently massaging the inflamed area can help unclog milk ducts.
Avoid excessive stress and fatigue – these can affect the immune system and promote the onset of mastitis.
Use correct breastfeeding techniques, such as proper positioning of the baby at the breast or alternating breasts at each feeding.
Consult a doctor, especially if symptoms persist or worsen.
If an infection is present and antibiotics are necessary, it is crucial to follow the treatment instructions.

Mastitis – Diagnosis and Treatment

Mastitis diagnosis usually begins with a thorough clinical evaluation by a doctor. The doctor will analyze the symptoms reported by the patient, such as breast pain, swelling, skin redness, and any nipple discharge. If the doctor suspects a bacterial infection, a breast biopsy may be necessary to identify the type of bacteria responsible. In some cases, a breast ultrasound is also recommended to rule out other more serious conditions.

Mastitis Treatment

In most cases, mastitis can be successfully treated at home with self-care measures. However, in some situations, medication may be necessary, which must be approved by a doctor.

Here’s what you should do when you have mastitis:

Follow Antibiotic Treatment – if mastitis is caused by a bacterial infection, the doctor will prescribe antibiotics to combat the infection. It is important to complete the antibiotic treatment, even if symptoms disappear before finishing the course.
Breastfeed Regularly – frequent emptying of the breast can help reduce inflammation and prevent milk from accumulating in the ducts.
Use Warm Compresses – applying warm or cold compresses to the affected area can help reduce pain and inflammation.
Get Enough Rest and drink at least 2 liters of fluids per day. Such measures are essential to support the immune system and for rapid recovery.
Don’t Forget Probiotics – in case of mastitis caused by a bacterial infection, the standard treatment usually involves antibiotics, such as penicillin or clindamycin. These help combat the bacterial infection but have a negative effect on gut flora, destroying beneficial bacteria. Therefore, it is essential to supplement antibiotic treatment with a probiotic and prebiotic supplement. Probiotics help restore gut flora, while prebiotics support the growth and activity of beneficial bacteria.

How long does mastitis take to go away?

If mastitis is treated properly, symptoms may begin to improve within 2-3 days; complete recovery can take between one week and 10 days. If symptoms persist or worsen, it is important to consult a specialist again to avoid complications.

Mastitis Without Breastfeeding – Which Groups are More Vulnerable?

Mastitis without breastfeeding, or non-lactational mastitis, can affect any woman, including those who do not have children. It can occur due to various causes, including hormonal imbalances, infections, or blockage of the milk ducts.

Here are the groups more prone to developing mastitis outside of breastfeeding:

Women in Menopause – mastitis can occur due to hormonal fluctuations during this period. Additionally, menopausal women may experience abnormal milk production, which can contribute to breast inflammation and infections.

Women with Weakened Immune Systems – they may develop non-lactational mastitis due to a bacterial or fungal infection. In fact, individuals suffering from autoimmune diseases, diabetes, or other conditions affecting immunity are more susceptible to mastitis.
Women Who Have Undergone Breast Surgery, such as breast reduction or biopsy, may be more vulnerable to non-lactational mastitis. Scars and tissue changes can promote milk stasis or duct blockage, creating conditions for infection.

What is the difference between lactational and non-lactational mastitis?

Lactational mastitis and non-lactational mastitis have similar symptoms but also important differences. Both forms can cause pain, swelling, and redness of the breast. However, lactational mastitis is often accompanied by fever and chills due to bacterial infections that frequently occur during breastfeeding. In this case, treatment focuses on frequent breastfeeding and antibiotics.

Non-lactational mastitis, on the other hand, is not related to breastfeeding and can occur due to hormonal imbalances, infections, or surgical procedures. Treatment varies depending on the cause and may include hormonal medications, antifungals, or antibiotics. It can affect any woman, including those who are not breastfeeding.

Consequently, whether we are talking about lactational or non-lactational mastitis, it is essential to act quickly and follow the doctor’s recommendations. Taking care of your health can help you get through this period more easily, so pay attention to your body’s signals and do not hesitate to seek specialist help!
