Introduction
Acute mastitis is a medical condition that occurs when the breast tissue becomes inflamed due to a bacterial infection. It typically affects women who are breastfeeding, but can also occur in women who are not breastfeeding. Acute mastitis is caused by bacteria, most commonly Staphylococcus aureus or Streptococcus species, entering the breast tissue through small cracks or openings in the skin. A fever, breast soreness, swelling, warmth, redness, and breast redness are some of the signs of acute mastitis.
What Is the Cause of Acute Mastitis?
Acute mastitis is caused by a bacterial infection in the breast tissue. The bacteria most commonly responsible for this infection are Staphylococcus aureus, which is found on the skin and in the nose, and Streptococcus species. These bacteria can enter the breast tissue through small cracks or openings in the skin, typically around the nipple.
During breastfeeding, the act of feeding can sometimes cause small cracks or sores in the nipple area, which provide an entry point for bacteria. If the breast is not adequately drained during feedings or pumping, milk can build up and create an environment where bacteria can thrive and cause an infection.
Other factors that can increase the risk of developing acute mastitis include:
-
Breast Engorgement: When the breast becomes engorged or overly full of milk, this can create an environment where bacteria can grow and cause an infection.
-
Blocked Milk Ducts: A blocked milk duct can create a backlog of milk in the breast, which can lead to inflammation and provide a breeding ground for bacteria.
-
Poor Breastfeeding Technique: Poor positioning or latching of the baby during breastfeeding can lead to insufficient draining of the breast, which can cause milk to back up and provide an environment for bacteria to grow.
-
Damaged Skin: Any cuts or scratches on the skin around the nipple area can provide an entry point for bacteria to enter the breast tissue.
-
Compromised Immune System: Women with weakened immune systems are more susceptible to infections, including acute mastitis.
What Are the Symptoms of Acute Mastitis?
Acute mastitis is characterized by a variety of symptoms that can vary in severity. The most common symptoms of acute mastitis include:
-
Breast Tenderness: The affected breast may be tender to the touch and feel sore or painful.
-
Swelling and Warmth: The breast may be swollen and feel warm to the touch. The skin may appear reddened or inflamed.
-
Lumps or Hardness: There may be one or more hard, tender lumps in the breast, which can be caused by a blocked milk duct.
-
Fever and Chills: In some cases, acute mastitis can cause a fever and chills, indicating a more serious infection.
-
Nipple Discharge: There may be pus or other discharge leaking from the nipple.
-
Fatigue: Women with acute mastitis may feel tired or run down, particularly if they have a fever.
-
Flu-Like Symptoms: Some women may experience flu-like symptoms, such as body aches, headache, and nausea.
In addition to these symptoms, women with acute mastitis may also experience pain or discomfort when breastfeeding, as the suction can exacerbate the inflammation in the breast. In some cases, the nipple may be cracked or blistered, making breastfeeding even more painful.
If left untreated, acute mastitis can lead to the formation of an abscess, a pocket of pus that forms in the breast tissue. An abscess can be particularly painful and may require surgical drainage.
How to Diagnose Acute Mastitis?
To diagnose acute mastitis, a healthcare provider will typically perform a physical exam and review the patient's medical history and symptoms. The provider may also order additional tests to confirm the diagnosis and determine the type of bacteria causing the infection.
During the physical exam, the provider will look for signs of inflammation, such as redness, swelling, and warmth in the affected breast. They may also palpate the breast to feel for lumps or areas of hardness. If the provider suspects an infection, they may order a breast ultrasound or mammogram to confirm the diagnosis and rule out other potential causes of breast inflammation, such as a breast abscess or breast cancer.
The provider may also perform a breast milk culture to determine the type of bacteria causing the infection. This involves taking a sample of breast milk and testing it in a laboratory to identify the specific type of bacteria present. This information can help guide treatment by ensuring that the appropriate antibiotic is prescribed. In rare cases, a breast biopsy may be necessary to rule out breast cancer as a potential cause of breast inflammation.
What Are the Treatment Option Available for Acute Mastitis?
The treatment of acute mastitis typically involves a combination of antibiotics, pain management, and self-care measures. The specific treatment plan will depend on the severity of the infection and the overall health of the patient.
-
Antibiotics: Antibiotics are typically prescribed to treat the bacterial infection causing acute mastitis. The choice of antibiotic will depend on the type of bacteria causing the infection and may be adjusted based on the results of a breast milk culture. Antibiotics are typically taken for 10-14 days, and it is important to finish the entire course of antibiotics, even if symptoms improve before the medication is complete
-
Pain Management: Over-the-counter pain relievers, such as Acetaminophen or Ibuprofen, can help manage breast pain and discomfort associated with acute mastitis. In some cases, the provider may prescribe a stronger pain medication.
-
Breastfeeding: It is important to continue breastfeeding or pumping milk to help clear the blocked milk ducts and promote breast drainage. The affected breast should be drained frequently, and the baby should be positioned to ensure proper latching and efficient feeding. If breastfeeding is too painful, the provider may recommend pumping and discarding the milk from the affected breast until the infection clears.
-
Warm Compresses: Applying a warm compress to the affected breast can help alleviate pain and discomfort and promote breast drainage. A warm shower or bath can also be helpful.
-
Rest and Fluids: It is important to get plenty of rest and stay hydrated by drinking plenty of fluids, such as water, juice, and broth.
-
Follow-Up: The provider may schedule a follow-up appointment to ensure that the infection is improving and to monitor for potential complications, such as an abscess.
In some cases, an abscess may form and require surgical drainage. In rare cases, hospitalization may be necessary, particularly if the infection is severe or if the patient has a weakened immune system.
Conclusion
Acute mastitis is a type of bacterial infection that affects the breast tissue and is often seen in women who are breastfeeding. This condition is caused by bacteria entering the breast tissue through small openings or cracks in the skin around the nipple area. The symptoms of acute mastitis include breast tenderness, warmth, swelling, redness, and fever. To treat acute mastitis, antibiotics are usually prescribed along with self-care measures such as warm compresses, pain management, and continuing to breastfeed or pump milk to clear any blockages in the milk ducts. If left untreated, acute mastitis can lead to the formation of an abscess which may require surgical drainage.
