What Is Mastitis?

Mastitis is a condition characterized by the inflammation of breast tissue, which can lead to symptoms such as pain, redness, and swelling. While it is often associated with individuals who breastfeed (lactational mastitis), it’s important to note that mastitis can also occur in people who are not breastfeeding (non-lactational mastitis). This comprehensive exploration delves into the various facets of mastitis, including its types, causes, risk factors, diagnosis, treatment options, prevention strategies, complications, and frequently asked questions.

Prevalence and Occurrence

Mastitis is a condition that affects a significant proportion of breastfeeding individuals worldwide. Studies indicate that up to 30% of people who breastfeed may experience mastitis at some point during their lactation journey. In the United States, it affects approximately 7-10% of breastfeeding individuals. Interestingly, mastitis is most commonly observed within the first three weeks following delivery, highlighting its relevance in the postpartum period.

Types of Mastitis

Mastitis can be classified into two primary categories: lactational mastitis and non-lactational mastitis. Healthcare providers may also categorize mastitis based on its severity, clinical presentation, and the presence of complications.

  • Lactational Mastitis: Lactational mastitis, also known as puerperal mastitis, is the most prevalent form of mastitis and predominantly occurs in individuals who are breastfeeding. Unlike non-lactational mastitis, this type is primarily attributed to prolonged breast swelling (engorgement) and bacterial infections, often resulting from inadequate milk drainage rather than a singular delay in breastfeeding.
  • Non-Lactational Mastitis: Non-lactational mastitis, on the other hand, is diagnosed in individuals who are not currently breastfeeding. It can arise from various causes, including blockages in the milk ducts, breast injuries, or infections in the breast tissue. Subtypes of non-lactational mastitis include periductal mastitis, which is benign and typically occurs in reproductive-aged women, and idiopathic granulomatous mastitis (IGM), an exceedingly rare form that often develops within five years of giving birth and can mimic breast cancer.
  • Other Classifications of Mastitis: Additionally, mastitis can be characterized by the presence or absence of complications, as well as by its recurrence. Uncomplicated mastitis is the most common category and typically involves mild to moderate symptoms that respond well to treatment. Complicated mastitis, however, involves more severe symptoms, abscess formation, or antibiotic-resistant infections, necessitating more aggressive treatment. Recurrent mastitis is diagnosed when individuals experience multiple episodes of mastitis.

Symptoms and Causes

The symptoms of mastitis can manifest in various ways, and they may include nipple pain, localized breast pain, swelling, fullness, or heaviness, changes in nipple appearance, redness and warmth in the affected area, itchiness over the breast tissue, tenderness in the armpit region, the presence of lumps or thickening in the breast, nipple discharge (which might be pus-like or bloody), and flu-like symptoms such as fever, chills, fatigue, or body aches.

Mastitis can be attributed to different causes based on its lactational or non-lactational nature. Lactational mastitis typically results from bacterial infections that enter the breast tissue through cracked or sore nipples, inciting an immune response that leads to inflammation. Staphylococcus aureus (staph) is a common culprit, with methicillin-resistant S. aureus (MRSA) emerging as a worrisome cause.

Additionally, milk duct blockage can contribute to mastitis, as stagnant milk accumulates, providing an ideal environment for bacteria to flourish. In non-lactational mastitis, the exact causes remain less clear but may be linked to factors such as autoimmune responses, infections, hormonal imbalances, high prolactin levels, or smoking.

Risk Factors

Several factors increase the risk of developing mastitis, including breastfeeding, especially in the early postpartum period. Cracked or sore nipples, improper latching during breastfeeding, infrequent or less frequent feeding, or consistently feeding in the same position can also elevate the risk. Other risk factors include inadequate milk removal, wearing restrictive clothing or bras, a weakened immune system, high levels of stress, insufficient sleep, smoking, and a history of previous mastitis episodes.

Diagnosis

Mastitis is generally diagnosed through a medical history review and a clinical examination by a healthcare provider. This examination may encompass inquiries about breastfeeding practices, nipple trauma, previous mastitis episodes, overall health, and the presence of flu-like symptoms. In addition to the clinical assessment, complicated mastitis cases may require further tests, such as breast ultrasounds, culture of nipple discharge to identify bacteria strains, blood tests to detect signs of infection, and in some cases, a biopsy to differentiate IGM from breast cancer.

Treatment

Treatment for mastitis may involve a combination of self-care measures and medical interventions. Home remedies can be effective, especially for mild cases. These remedies include regularly emptying the breast through pumping or breastfeeding, massaging the painful area, changing breastfeeding positions, prioritizing rest, staying hydrated, applying cool compresses, and using over-the-counter pain relief medications like acetaminophen or ibuprofen.

Medical treatment becomes necessary if symptoms persist, worsen, or if complications such as an abscess develop. Healthcare providers may prescribe antibiotics, corticosteroids, or immunosuppressants to address the infection and inflammation. Surgical drainage or duct removal may be required in severe cases.

Prevention

Preventing mastitis involves a proactive approach that includes proper latching during breastfeeding, regular milk removal to prevent milk stasis, avoiding sudden weaning to reduce engorgement risk, varying breastfeeding positions, maintaining breast hygiene, avoiding harsh soaps or lotions that can cause nipple cracking, and using lanolin or breast milk to treat sore or cracked nipples. Loose-fitting, comfortable clothing and bras can also contribute to unrestricted milk flow. Seeking guidance from lactation consultants can be immensely helpful for individuals with concerns about breastfeeding techniques.

Complications

Untreated mastitis can lead to various complications, including difficulties with breastfeeding, the formation of breast abscesses, the development of milk blisters (blebs), recurrent or chronic mastitis, and challenging emotional experiences for affected individuals. It’s worth noting that most people fully recover from mastitis without long-term complications, especially when treatment is initiated promptly and followed diligently.

Frequently Asked Questions

Can mastitis go away on its own?

  • While some mild cases of mastitis may resolve spontaneously, prompt treatment, including antibiotics if necessary, promotes a quicker recovery and reduces the risk of complications such as abscess formation.

Can pumping help mastitis?

  • Yes, continuing breastfeeding or pumping is beneficial in clearing the infection and maintaining milk supply. However, it’s essential to consult a healthcare provider regarding any restrictions on breastfeeding or milk disposal if specific antibiotics are prescribed.

Can babies drink breast milk if you have mastitis?

  • Babies can typically consume breast milk unless a healthcare provider advises otherwise due to specific antibiotics. In such cases, pumping and discarding the milk helps maintain milk supply and clear the infection.

When should I see a doctor for mastitis?

  • It is advisable to consult a healthcare provider when experiencing mastitis symptoms. Medical attention is especially crucial if symptoms persist beyond 12-24 hours, worsen, include flu-like symptoms or nipple discharge, or if there is a history of recurrent mastitis or abscess formation.

In conclusion, mastitis is a common condition with various facets, ranging from its types, causes, and risk factors to diagnosis, treatment, prevention, and potential complications. Understanding this condition empowers individuals to seek timely and appropriate care, ensuring a smoother recovery and minimizing the risk of complications. Additionally, knowing the preventive measures can aid in reducing the likelihood of developing mastitis, promoting a healthier breastfeeding experience and overall breast health.
