About Mastitis (Breast Infection)
The main causes of mastitis are milk stasis and infection. Milk stasis occurs when the milk ducts in the breast become blocked or stagnant, which can happen when milk is not effectively removed from the breast. This can lead to inflammation and discomfort. In some cases, milk stasis may progress to an infection, which can further worsen the symptoms of mastitis.
Non-modifiable risk factors for mastitis are factors that can’t be changed, including:
- Sex: Mastitis is most common in women, but it can also occur in men.
- Pregnancy: Mastitis is more likely to occur in women who have recently given birth.
- Age: Younger women (under 21) and older women (over 35) may have a higher risk of mastitis.
- Previous mastitis: Women who have had mastitis before may be more prone to developing it again.
Modifiable risk factors for mastitis are factors that can be influenced or changed, including:
- Breastfeeding: Mastitis is most commonly associated with breastfeeding. Women who are breastfeeding are at a higher risk of developing mastitis compared to those who are not breastfeeding.
- Incorrect breastfeeding technique: Improper positioning or latching during breastfeeding can contribute to milk stasis and increase the risk of mastitis.
- Cracked or sore nipples: Damaged nipples can make it more difficult for milk to flow properly, leading to milk stasis and potentially infection.
- Stress: High levels of stress can weaken the immune system and make it harder for the body to fight off infections, including mastitis.
- Smoking: Smoking has been identified as a potential risk factor for mastitis.
It's important to note that while some risk factors for mastitis cannot be changed, such as sex and pregnancy, there are steps that can be taken to reduce the risk of developing mastitis. This includes practicing proper breastfeeding techniques, maintaining good nipple hygiene, managing stress levels, and quitting smoking if applicable.
The most common early symptoms of mastitis include:
- Breast swelling
- Redness, sometimes in a wedge-shaped pattern
- Breast tenderness or sensitivity
- Pain or burning sensation while breastfeeding
- Chills, headache, or flu-like symptoms
- A fever of 101°F (38.3°C) or higher
As the infection progresses or becomes more severe, other common symptoms may occur. These can include:
- Tenderness in the breasts
- Breasts that are warm to the touch
- Swelling of the breasts
- Pain or burning sensation (which can be constant or only while breastfeeding)
- A lump in the breast or thickening of breast tissue
- Redness and swelling of the breast
- Feeling sick or rundown
- Fever and chills
In some cases, if the infection is left untreated, it can develop into a collection of pus called an abscess in the breast tissue. This may require surgery to drain the pus. It's important to seek medical treatment if you suspect mastitis to prevent complications and ensure proper management of the infection.
To diagnose mastitis, doctors typically perform the following examinations, tests, and procedures. including:
- Physical examination: A doctor will examine the affected breast and ask about symptoms. They will look for signs of inflammation, such as redness, swelling, and warmth.
- Medical history: The doctor will ask about any previous episodes of mastitis or breast infections, as well as any breastfeeding issues.
- Breast milk sample: In some cases, when symptoms are severe or if there’s no response to treatment, the doctor may take a small sample of breast milk for testing. This test can determine whether there is a bacterial infection and identify the type of bacteria present, which helps guide treatment.
- Breastfeeding demonstration: If a breastfeeding problem is suspected as the cause of mastitis, the doctor may ask the woman to demonstrate how she breastfeeds. This can help identify any issues with positioning or latch that may contribute to the infection.
In addition to these diagnostic procedures, there are additional examinations, tests, and procedures that can be used to determine the stage or severity of mastitis:
- Imaging tests: Depending on the severity of the infection, imaging tests such as ultrasound or targeted breast ultrasound may be performed. These tests can help visualize the extent of inflammation and identify any abscesses or other complications.
- Biopsy: In rare cases where there is concern about inflammatory breast cancer or when other diagnostic methods are inconclusive, a biopsy may be taken. A biopsy involves removing a small sample of breast tissue for further examination under a microscope to rule out breast cancer.
It's important to note that these additional tests are not always necessary for diagnosing mastitis. They are typically reserved for cases where there is uncertainty about the diagnosis or when complications are suspected.
The goals of treatment for mastitis are to relieve symptoms, eliminate the infection, and prevent complications. Different types of treatments for mastitis include:
- Antibiotics: Antibiotics are medications that help fight bacterial infections. They are commonly prescribed for mastitis caused by bacteria. These medications work by killing or inhibiting the growth of bacteria, helping to eliminate the infection. It’s important to complete the full course of antibiotics prescribed by the doctor, even if symptoms improve before finishing treatment. This helps ensure that all bacteria causing the infection are fully eliminated.
- Self-Help Remedies: Self-help remedies can be tried as the first treatments for mastitis. These remedies include ensuring proper drainage of the breast during feeds, which can help relieve symptoms and prevent further infection. Techniques such as massaging the breast, applying warm compresses, and using different breastfeeding positions may also be recommended to promote better drainage.
- Pain and Fever Relief: Mastitis can cause pain and fever, which can be managed with over-the-counter pain relievers such as acetaminophen. These medications help reduce pain and inflammation, making the person more comfortable while their body fights off the infection.
- Drainage Procedures: In some cases, a breast abscess may form, which is a tender lump containing pus. If this happens, a doctor may perform a drainage procedure to remove the abscess. This procedure involves creating a small opening in the skin using a scalpel blade and either inserting a drain or allowing natural drainage. By draining the abscess, pain is reduced, and further infection is prevented.
- Health Behavior Changes: Making certain changes in health behaviors can also aid in the treatment of mastitis. Continuing to breastfeed or express milk regularly helps ensure proper drainage of the breast and prevents milk from building up and worsening the infection.
It is worth noting that some studies suggest that antibiotics may not always be necessary or appropriate during breastfeeding for mastitis treatment. In these cases, non-medicinal remedies and self-help measures should be tried first. However, if complications occur or if the condition worsens quickly, hospitalization and antibiotic treatment may be recommended.
If mastitis is not treated, it can lead to complications. One common complication is an abscess, which is a collection of pus that develops in the breast. Surgical draining is usually necessary to treat an abscess. Another potential complication is septicemia or sepsis, which are life-threatening conditions that can occur if the infection is not treated promptly.
Early treatment is key in preventing complications and promoting quicker recovery. If mastitis has occurred once, there is a higher likelihood of recurrence (returning) if it is not properly treated. Late or inadequate treatment can add to the risk of recurrence. In some cases, surgical draining may be required for an abscess.
It's important to note that while home remedies or over-the-counter medications may provide temporary relief for mastitis symptoms, it's always best to consult with a healthcare professional for proper diagnosis and treatment. They can provide personalized advice based on your specific situation.
