Are you about to become a mother? Or are you already a mother of a beloved baby? However, you probably have a lot of questions about breastfeeding, that is, the process of milk production (Lactation). Let's talk about it all today in a simple way that you can understand, okay?
How is breast milk produced? What happens inside the breast?
Okay, now let's take a look at this amazing milk-making machine, that is, what goes on inside your breasts. Think of the mammary glands inside your breasts as a little milk factory. They have a few main parts:
- Alveoli: These are the small grape-like sacs. This is where milk is made and stored temporarily. Many of these alveoli are grouped together to form clusters of glands called lobules. A lobule is connected to a lobe.
- Milk ducts: Each lobe has one milk duct. There may be up to 20 lobes in your breast. These ducts carry milk from the alveoli to the nipple.
- Areola: The dark area around the nipple is called the areola. It has a lot of very sensitive nerve endings. When the baby sucks, these nerves tell the brain, "Okay, let the milk out now." Milk comes in when the entire areola is stimulated.
- Nipple: There are about 20 tiny holes in the nipple, and milk comes out of these holes. When the baby sucks milk (or when you express it by hand, or when you pump it with a breast pump), the nerves in this nipple are stimulated. This stimulation sends a signal to the brain to let the milk from the alveoli come down the milk ducts and out of the nipple.
Simply put, think of this milk-making system as a big tree. Your nipple is the trunk of the tree. The milk ducts are the branches. The leaves are the alveoli.
Why do we get milk?
So, the main reason is to feed our baby. This is a natural, hormonally controlled thing. Milk is produced in this way during and after a baby is born to provide the necessary nutrition for the newborn. Special hormones in our body are what start this milk production and milk coming out. All mammals feed their young in this way. The amazing thing is, if you use the right hormonal drugs, you can even make someone who is not pregnant produce milk.
How does milk production begin? What are the stages of this?
The process of making milk begins with a series of hormonal changes that occur after you become pregnant. We call this process ``Lactogenesis.'' There are three main stages to this.
Stage one lactogenesis - begins during pregnancy!
This stage begins around 16 weeks into your pregnancy and lasts until a few days after the baby is born.
- The hormones estrogen and progesterone increase. This causes the milk ducts in your breasts to increase in size and shape. Your breasts may feel a little bigger and fuller. The mammary glands are getting ready to make milk.
- Your nipples will become darker and your areola will also become larger.
- The small bumps (`Montgomery glands`) in the areola secrete an oil-like substance to keep the nipple moist.
- Most importantly, your body will start producing colostrum, the first milk your baby will have, which is very nutritious.
Stage two lactogenesis - How milk comes in after having a baby!
This stage begins about two to three days after the baby is born. This is when milk production accelerates.
- After your baby and placenta are delivered, estrogen and progesterone levels suddenly drop. Then a hormone called prolactin starts working.
- Prolactin is the main hormone that makes milk.
- You'll notice that milk production suddenly increases a lot during this time. We say 'milk is flowing', that's what it is.
- Often these days , the breasts are filled with milk, become hard, and may feel painful and engorged.
Stage three (`Stage three lactogenesis`) - the time for continued breastfeeding!
This is the entire period of your breastfeeding.
- Normally, milk production will continue as long as your breasts are drained.
- As the amount of milk removed increases, your body makes more milk to fill the gap. You can make more milk by breastfeeding your baby more often or by pumping.
What hormones help produce milk?
You probably understand now how important hormones are to this milk production process. The main thing that controls the amount of milk you make is a hormone called prolactin. Your body starts making this prolactin in the early stages of pregnancy. However, at first, the work of prolactin is somewhat suppressed due to the increased levels of hormones like estrogen and progesterone during pregnancy. After the placenta comes out, as those pregnancy hormones decrease, prolactin takes over.
When the baby sucks on the nipple, it stimulates nerves and tells the brain to release two hormones called prolactin and oxytocin . Prolactin causes milk to be produced in the alveoli. Oxytocin causes the muscles to contract and push the milk out of the alveoli and into the milk ducts.
The process of milk coming out is called ``letdown'' . This ``letdown'' occurs about 30 seconds after the baby starts sucking. These hormones are not limited to one breast, so ``letdown'' can cause milk to be released from both nipples at the same time.
If you are not pregnant, inducing lactation involves using medications that mimic the hormones your body makes during pregnancy. Stimulating your breasts – either with a breast pump or by breastfeeding – can help to start your milk production. This is a complex process, so it is important to work with a doctor who understands your needs and is experienced in this area.
Does milk start coming in during pregnancy?
Yes, it may seem strange, but you can start making milk as early as a few weeks after you become pregnant and enter the second trimester. As estrogen and progesterone levels increase, your body prepares to make milk. The number of milk ducts in your breasts increases. These ducts carry milk from the alveoli to the nipples. Around mid-pregnancy, your body starts making colostrum . This is the first milk your baby will receive.
Can you breastfeed without being pregnant?
Yes, you can make milk without being pregnant. This is called inducing lactation. It is a somewhat complicated process. It usually takes several months of hormone-mimicking drugs to make milk. The second part of making milk is expressing milk from the nipple. When a baby sucks, uses a breast pump, or expresses milk by hand, the brain sends signals to the breast to let the milk out. A doctor can help you with this process.
How do I stop milk coming in?
There are many reasons why you might want to stop producing milk. You can stop producing milk naturally, or you can do this using hormonal medications.
How to reduce milk supply naturally:
Milk production is a supply-demand process. This means that as your baby's reliance on breast milk decreases, or as you reduce the frequency of breastfeeding or pumping, your milk supply will gradually decrease. Simply put, if you reduce the amount of milk you remove from your breasts, your body will gradually reduce its production.
When your milk stops coming in, you may feel a little uncomfortable. Many people experience engorgement. This can be caused by leaking milk or a blocked milk duct. However, you can reduce this pain by using an over-the-counter pain reliever, wearing a supportive bra, or placing an ice pack on your breast.
How to stop lactation with medication:
There are also medications that can stop milk production. Your doctor can tell you more about these medications, their benefits, and side effects.
Where are the mammary glands located?
Mammary glands are what we commonly call breasts. Everyone has them. They are located in the chest. They are made up of connective tissue, fat, and special glandular tissue that makes milk. Women's glandular tissue is a little different, because they have alveoli and lobules that make milk. Women also have a lot more glandular tissue.
What are the common conditions that affect the ability to breastfeed?
Lactation ability and the length of time you can produce milk varies from person to person. Some people can produce milk for years, while others may have difficulty producing milk for their baby.
Here are some common factors that can affect lactation or breastfeeding:
- Hormone levels and hormone-related conditions.
- The medicine you take.
- If you have previously received radiation therapy.
- Trauma to the breasts or nipples.
- If you have had breast augmentation, reconstruction, or other breast surgery.
- Other medical conditions, such as HIV infection.
- Drug and alcohol use.
If you are breastfeeding or bottle-feeding your baby, you should always talk to your doctor before starting any new medication or treatment. Many medications can pass into breast milk and may have harmful effects on your baby.
What is the absence of menstruation during breastfeeding (Lactational amenorrhea)?
Lactational amenorrhea is when you stop having periods because you are breastfeeding. When you are breastfeeding, your body produces a hormone called prolactin, which is the hormone that makes milk. This prolactin reduces the amount of luteinizing hormone (LH) in your body. This LH helps your body release an egg during ovulation. If your body doesn't produce LH, you won't ovulate and you won't get your period. This loss of menstrual flow due to breastfeeding can last for several months, until you stop breastfeeding completely.
Does breastfeeding reduce my risk of developing diseases?
Yes, that's true. Studies have shown that breastfeeding reduces your risk of developing ovarian cancer and breast cancer . It also helps reduce your risk of developing type 2 diabetes and high blood pressure.
How to maintain milk production?
Maintaining milk supply is also largely based on supply and demand. The more your baby sucks, or the more you express with a breast pump, the more milk your body will make. There are ways to reduce your milk supply, whether it's through hormones or birth control pills. If you want to continue breastfeeding, here are a few things you can do:
- Feed your baby whenever he asks, or pump frequently (about every four hours).
- Eat a healthy diet with enough calories. Low-calorie foods can reduce milk supply.
- Drink plenty of water and stay hydrated. Breast milk is mostly water.
- Avoid smoking, drugs, or alcohol. These can decrease your milk supply and can also be added to your milk.
What is the difference between Lactation and Colostrum?
Lactation is the entire process of making and releasing milk from your breasts. Colostrum is the first milk produced by your breasts during breastfeeding, and the first milk your baby drinks. It is thick, yellow, and often referred to as 'liquid gold'. Colostrum is rich in protein, minerals, vitamins, and antibodies.
What does hormone therapy to induce milk production mean?
Couples or families who want to induce lactation for reasons such as adoption or surrogacy may want to try hormone therapy. Induced lactation is the process of developing a milk supply without getting pregnant. This involves taking hormones such as estrogen and progesterone for several months to trick your body into thinking you are pregnant. This prepares your breasts to make milk. Some medications and herbs are also believed to help develop a milk supply.
A few weeks before your baby arrives, you should start pumping your breasts with a breast pump. This stimulates your body to release prolactin, which is what makes milk. In other words, you should express your milk several times a day, just like you would with a baby. This will help build up your milk supply. You can also freeze the milk you make to give to your baby after he or she arrives.
If you are thinking about this, you should talk to your doctor about your desire to breastfeed your baby. Induced lactation is successful for many people, but it is not successful for everyone.
Finally, things to remember
If you want to breastfeed your baby, it's important to understand the process of lactation so you know what to expect. Talk to your doctor about how to best prepare for breastfeeding or expressing milk. Remember, breastfeeding can be different for everyone, depending on your circumstances and health history.
If you have a problem with breastfeeding, you may feel embarrassed or even sad. But it's very common to have problems with breastfeeding. Lactation specialists and other healthcare providers can help you overcome these difficulties.
