The causes of mastitis are firstly bacterial invasion and secondly the accumulation of milk. The accumulation of milk mainly occurs during breastfeeding, due to the position of holding the child or unintentional bumps by the child, which cause damage to the milk ducts, constriction of the ducts, leading to a large amount of milk being trapped inside the ducts. Since milk is an excellent culture medium, it results in bacterial growth. Bacterial invasion usually occurs through cracked or fissured nipples, allowing bacteria to enter the milk ducts and into the breast tissue, causing mastitis. Another situation is a decrease in the body's immune system, for example, due to poor sleep or emotional stress. These are the main causes of acute mastitis.

The causes of acute mastitis

The main causes of mastitis are as follows: First, the accumulation of milk is due to improper breastfeeding techniques or incidental contact with the mammary glands by the child, which causes the milk ducts to close and ultimately leads to the accumulation of milk. Milk is an ideal culture medium that facilitates bacterial growth, leading to mastitis. Second, bacterial invasion occurs when there are cracks or abrasions on the nipple, allowing bacteria to travel along the milk ducts to reach and infect the mammary lobules. Lastly, a decrease in the patient's own immune system can also lead to bacterial infection.

Does acute mastitis require milk dredging?

During acute mastitis, it is necessary to apply local heat and then clear the milk ducts by stroking them to drain excess milk. If milk stasis occurs in the ducts, it can aggravate inflammation and, in severe cases, lead to the formation of a breast abscess. Once a breast abscess forms, it requires incision and drainage, so it is essential to completely drain any residual milk during acute mastitis. For acute pancreatitis, prevention is more important than treatment. The specific methods include maintaining nipple cleanliness during breastfeeding, frequently washing the nipples with warm soapy water, developing good breastfeeding habits, breastfeeding regularly, ensuring that the milk is fully drawn each time, and if not, either manually expressing or using a breast pump. Additionally, avoid letting the baby sleep with the nipple in their mouth.

How should acute mastitis be treated?

Firstly, it is essential to prevent the accumulation of milk and avoid damage to the nipples while keeping them clean. After each breastfeeding, wash the nipples with soap. If the nipples are inverted, frequently squeeze and pull them to correct this. It is important to establish a regular breastfeeding schedule to prevent the baby from sleeping without releasing the nipple. Each breastfeeding session should drain the milk completely; if there is any accumulation, massage or use a breast pump to extract all the milk. After breastfeeding, clean the nipples. If there is any damage or cracking on the nipples, timely treatment is necessary. For the care of the baby's oral cavity, local heat application and massage can be provided.

Can I eat eggs with acute mastitis?

Patients with acute mastitis can eat eggs, but should not consume them in excess, as too many can lead to increased accumulation of body fat and elevated cholesterol levels. Prevention is more important than treatment for mastitis, and specific methods include maintaining nipple cleanliness during lactation. Frequently wash with warm, soapy water, and nipples can also be washed with 3% boric acid water before and after breastfeeding. For those with inverted nipples, gently squeeze out the nipple before washing. It is important to develop good breastfeeding habits, breastfeed on a schedule, and ensure that all the milk is drawn out each time. If the milk cannot be fully expressed, use hand massage or a breast pump. Additionally, do not let the baby suckle while sleeping. If there is nipple damage or cracking, stop breastfeeding, use a breast pump to extract milk, and resume breastfeeding once the wound has healed.

What is acute mastitis?

Acute mastitis is an acute purulent infection of the mammary gland, commonly occurring in women during the postpartum breastfeeding period, especially more frequently seen in primiparous women. It usually occurs within three months after delivery, particularly in the third and fourth weeks postpartum. Therefore, it can also be referred to as postpartum mastitis or lactational mastitis. The main causes are due to bacterial invasion, stagnation of milk, and a decrease in the body's immune function. The primary pathogens are generally Staphylococcus aureus, with occasional cases involving Streptococcus. In such instances, it is recommended to conduct a routine blood test for the mammary gland and an ultrasound to determine the severity of the mastitis.
