1. Introduction
Both engorgement and mastitis cause breast pain and swelling, but their management differs. Misunderstanding the difference can delay treatment and increase complications. Mothers need to know when self-care is enough and when antibiotics or medical attention are necessary.
2. Normal Engorgement
-
Timing: Usually occurs when milk “comes in” (day 3–5 postpartum) or when feeds are skipped/delayed.
-
Symptoms:
-
Both breasts feel heavy, full, firm, sometimes shiny.
-
Nipple may be flat, making latch harder.
-
Tender but no systemic symptoms (fever, chills).
-
-
Relief: Improves with frequent feeding, hand expression, warmth before feeding, and cold compresses after.
3. Mastitis
-
Definition: Inflammation of breast tissue, often with infection.
-
Causes: Blocked duct, prolonged engorgement, nipple cracks (entry point for bacteria).
-
Symptoms:
-
Usually affects one breast.
-
Red, wedge-shaped area of swelling and pain.
-
Fever (>38 °C), chills, flu-like symptoms (aches, fatigue).
-
Pain does not resolve after feeds.
-
-
Complications if untreated: Abscess formation, early weaning.
4. Key Differences (Engorgement vs. Mastitis)
Feature | Engorgement | Mastitis |
---|---|---|
Onset | Day 3–5 postpartum or missed feeds | Any time during lactation |
Location | Both breasts, generalized | Usually one breast, localized area |
Fever/systemic signs | Absent | Present (fever, chills, body aches) |
Relief after feeds | Improves significantly | Persists, often worsens |
5. When Antibiotics May Be Needed
-
Indicated if:
-
Mother has fever + localized painful red area.
-
Symptoms do not improve within 12–24 hours of supportive care.
-
Suspected bacterial infection (pus from nipple, worsening cracks).
-
-
Not usually needed for:
-
Normal engorgement.
-
Simple blocked duct without systemic symptoms.
-
-
Safe antibiotics for breastfeeding mothers (doctor prescribed):
-
Dicloxacillin, flucloxacillin, or cephalexin (first-line).
-
For MRSA risk: clindamycin or TMP-SMX (if baby >2 months).
-
6. Self-Care While Awaiting Medical Review
-
Continue breastfeeding or expressing from affected breast (safe for baby).
-
Rest, hydrate, eat well.
-
Apply warm compress before feeds, cold after.
-
Wear supportive but non-tight bra.
End of Lecture Quiz
Q1. Which of the following is a sign of mastitis rather than engorgement?
A. Both breasts swollen and heavy
B. Fever and chills
C. Breasts feel full on day 3 postpartum
D. Pain improves after breastfeeding
Answer: B. Fever and chills
Rationale: Systemic infection signs distinguish mastitis from normal engorgement.
Q2. True or False: Mothers should stop breastfeeding if they develop mastitis.
Answer: False
Rationale: Continuing to breastfeed/express helps clear infection and prevents worsening.
Q3. Which is the first-line treatment for normal engorgement?
A. Immediate antibiotics
B. Frequent feeding and hand expression
C. Breast binding
D. Stopping breastfeeding
Answer: B. Frequent feeding and hand expression
Rationale: Engorgement resolves with effective milk removal, not antibiotics.

Key Takeaways
-
Engorgement = full, heavy breasts without fever → usually resolves with frequent feeds.
-
Mastitis = painful, red, one-sided swelling + fever → may require antibiotics.
-
Early recognition prevents complications like abscess and early weaning.
-
Breastfeeding should continue during both engorgement and mastitis.
Call to Action
-
Mothers: Seek medical help if fever or flu-like symptoms accompany breast pain.
-
Health workers: Teach mothers to spot the difference early.
-
Communities: Encourage supportive environments where mothers rest and feed often.
