Condition Basics

What is mastitis?

Mastitis is an inflammation of the breast. It occurs most often in people who are breastfeeding or pumping breastmilk. The inflammation occurs when the milk sacs in the breast are too full and cause swelling in the breast tissue.

Mastitis can leave you feeling very tired and run-down. If you have mastitis, it is important to keep breastfeeding, as stopping suddenly can make it worse. Treating mastitis right away helps prevent an infection from happening. Depending on your symptoms, your healthcare provider might prescribe antibiotics.

What causes it?

One of the main causes of mastitis is when your breasts become too full and make more milk than your baby needs. If this is happening, talk to your healthcare provider about ways to manage your breastmilk production.

What are the symptoms?

If you have mastitis, you may first notice:

• A painful area on one breast. It may be red, warm to the touch, or both.
• Chills, aches, and flu-like symptoms.
• A fever.

If your symptoms are getting worse, the mastitis could be turning into an infection. This infection could lead to a breast abscess, which feels like a hard, painful lump.

How is it diagnosed?

Your doctor can usually diagnose mastitis based on your symptoms and by checking your affected breast. Tests usually aren't needed.

Prevention

Taking these steps can help prevent mastitis.

• Breastfeed regularly. If you know you'll go more than 4 hours without feeding your baby, arrange to pump.

• If you are pumping, only pump as much milk your baby needs. Pumping too much can cause your body to make too much milk. This can cause mastitis.

• Drink plenty of fluids.

  If you drink something while you breastfeed, it can help you stay hydrated.

• Position yourself well.

  When you and your baby are aligned, the baby can latch on to the areola, not just the nipple.

• Use different positions.

  This can help drain all areas of your breast. Try breastfeeding positions such as the Australian hold, the cradle hold, the cross-cradle hold, the football hold, and the side-lying position.

• Alternate which breast you offer first.
• Wear a bra that isn't too tight or restrictive.
• Take care of your nipples.
  • Air-dry your nipples after you breastfeed. This can prevent irritation and cracking.
  • If your nipples are sore or cracked, put expressed breastmilk on your nipples to help them heal.
  • Get help from your doctor or a lactation consultant for sore or cracked nipples.

Symptoms

If you have mastitis, you may first notice:

• A painful or hardened area on one breast. It may be red, warm to the touch, or both.
• Chills, aches, and flu-like symptoms.
• A fever.

Signs that mastitis is getting worse include a fast heart rate, and flu-like symptoms that get worse.

The symptoms of mastitis most often appear within 4 to 6 weeks after childbirth.

In some cases, symptoms of mastitis may get worse and the breast forms a pocket of pus (abscess) in the infected area.

Symptoms of a breast abscess

Symptoms of a breast abscess include a breast lump that is hard and painful and a reddened area on the breast. You may also have flu-like symptoms that are getting worse.

Examinations and Tests

Your doctor can usually diagnose mastitis based on your symptoms and by checking your breasts. Tests usually aren't needed. But tests may be done to confirm a diagnosis. They may also be done to help guide treatment for other problems that can develop.

If you have an infection that isn't improving with treatment, your doctor may do a breast milk culture. To provide a sample for a culture, you will squeeze a small sample of milk from the affected breast onto a sterile swab. The culture results help your doctor confirm a diagnosis and find out the specific bacteria causing the infection.

Culture results may also be used to find out which antibiotic will work best for you.

Diagnosing a breast abscess

Your doctor can diagnose a breast abscess by checking your breast. If an abscess is too deep to check by touching it, your doctor may use a breast ultrasound. Ultrasound can also guide a needle to drain the abscess. A culture can then be done to identify the bacteria that are causing the abscess.

Treatment Overview

Mastitis won't go away without treatment. Treating it right away helps keep the inflammation from quickly getting worse and usually eases symptoms after about 2 days. Delaying treatment can lead to an abscess, which can be harder to treat.

Treatment usually includes:

• Continuing to regularly breastfeed or pump breast milk. If you are pumping, only remove the amount of milk your baby needs. When you remove too much milk, your body will start making more than you need. This can make the mastitis worse.
• Self-care. This includes varying your breastfeeding positions and taking acetaminophen to relieve pain, fever, or discomfort. You can rest as needed and use an ice pack on your breast.
• If the mastitis turns into an infection, your doctor will prescribe you antibiotics. Antibiotics destroy the bacteria that are causing the infection.

It is best to keep breastfeeding your baby or pumping breast milk to feed your baby during illness and treatment. Your breast milk is safe for your baby to drink. Any bacteria in your milk will be destroyed by the baby's digestive juices.

Treating a breast abscess

Treatment for a breast abscess includes:

• Draining the abscess. Healing can take 5 to 7 days.
• Antibiotics that you take by mouth. They destroy the bacteria that are causing the infection. Antibiotics are given through a vein (intravenously) only in rare cases of severe infection.
• Continue breastfeeding or pumping, removing only the amount of milk your baby needs. This is also very important for keeping a good milk supply.

Most people can keep breastfeeding with the affected breast while an abscess heals. With your doctor's approval, you can cover the abscess area with a light gauze dressing while your baby breastfeeds.

If you are told to stop breastfeeding your baby from the affected breast while an abscess heals, you can keep breastfeeding from the healthy breast. Be sure to pump or express milk from the infected breast regularly.

Self-Care

Taking antibiotics if they are prescribed and continuing to breastfeed or pump will help clear up mastitis. You can also take these steps to feel better.

• Take an over-the-counter medicine.
  • Acetaminophen (such as Tylenol) can help with pain, fever, or discomfort.
  • You can also take ibuprofen (such as Advil) along with acetaminophen to reduce inflammation.
• Rest as much as you can.
• Use an ice pack or cold compress to reduce pain and inflammation in the sore breast.

  Cold and heat can reduce pain in the sore breast.

  • If you use an ice pack, place it on the outside of your bra or clothes.
  • Do not put the ice on your bare skin.
• Use a warm compress for short amounts of time only. Heat can make the inflammation worse.
• Drink extra fluids.
• Hand express or pump a little first if your breasts are very full (engorged).

  A breast that isn't quite so full can be easier for your baby to latch on to.

• Wash off pus.

  If pus drains from your nipple, gently wash it off. Let your nipple air dry before you put your bra back on. You can also use a disposable breast pad to absorb the pus.

If you have trouble breastfeeding, you can get more help and support from your doctor or a lactation consultant.

Breastfeeding when you have mastitis

• Breastfeed often.

  Your baby is the most efficient way to remove milk from your breasts. And your milk is safe for your baby to drink. Your baby's digestive juices will destroy any bacteria in your milk.

  • Try to start on the sore side.
  • If you need to start on the other side, be sure to switch and feed from the affected breast.
  • Vary your breastfeeding positions to help the milk flow.
  • If it's too painful to breastfeed at all, you can pump or hand express your milk.
• Use a warm, wet face cloth on your sore breast.

  The heat from the face cloth can help increase milk flow.

  • Place the face cloth on the affected breast 15 minutes before you start to breastfeed.
  • Try this at least 3 times a day.
• Apply expressed breastmilk to sore or cracked nipples.
• Replace nursing pads often.

  Dry and clean pads are best.
