Yes, the high levels of prolactin during breastfeeding can contribute to weight gain or make weight loss difficult for some mothers by increasing appetite and promoting fat storage as "insurance" for milk production, though individual experiences vary due to metabolism, diet, sleep, and stress. While many lose weight, prolactin's role in fat storage and appetite stimulation can counteract this in others, alongside other factors like sleep deprivation and stress.
Recent research suggests that hyperprolactinemia causes an abnormal lipid profile, weight gain, and cardiovascular diseases. Moreover, high prolactin levels lead to decreased testosterone production by disrupting 17-b-estradiol synthesis.
Avoid consuming sugary drinks, processed foods, and foods that are high in sugar. Also, make sure to consume enough protein and fibre in your diet. This will help to keep your blood sugar stable and help to reduce prolactin levels.
Symptoms and Causes
Consume Foods That Help Regulate Blood Sugar Levels
Balancing blood sugar levels can help reduce prolactin levels. Therefore, it is essential to avoid sugary drinks and processed foods high in sugar.
Amylin. Amylin is a hormone produced in the pancreas and decreases food intake. In experiments it has been shown to reduce Leptin Resistance and cause weight loss. It is used in the treatment of diabetes for lowering sugar but can have a role in weight loss management.
A hormone that can quietly raise your appetite, slow down your metabolism, and convince your body to store fat even when you're trying your hardest to lose it.
Prolactin and cortisol levels return to normal within days of weaning. Without nipple stimulation from nursing or pumping, oxytocin levels remain low. The breast glands begin to return to their pre-pregnancy size and structure.
Symptoms in women include irregular periods, milky breast discharge, and low estrogen. Men may experience low libido, erectile issues, or breast enlargement. Diagnosis involves a blood test for prolactin levels and medical imaging to check for a pituitary tumor.
Prolactin may be implicated in the alterations in female sleep patterns observed during the reproductive cycle, it may play a role in the REM sleep enhancement following stress and in sleep-related immunological processes.
More prolactin is produced at night, so breastfeeding at night is especially helpful for keeping up the milk supply. Prolactin seems to make a mother feel relaxed and sleepy, so she usually rests well even if she breastfeeds at night.
The "4-4-4 rule" for breast milk is a simple storage guideline: fresh milk is good for 4 hours at room temperature (up to 77°F/25°C), for 4 days in the refrigerator (39°F/4°C or colder), and up to 4-6 months (or longer) in a standard freezer (0°F/-18°C). It's a handy mnemonic, though some organizations like the CDC recommend up to 6 months in the freezer and the AAP up to 9 months, with deeper freezers offering even longer storage.
If you are looking for how to balance your hormones while breastfeeding, get back to the basics. Prioritize nourishing food, gentle movement, sleep (as you are able), and foundational supplements to support your own health and the health of your newborn.
"The thyroid gland is a huge determinant of the body's basal metabolic rate, so even subtle disruptions in thyroid hormone can slow metabolism and ultimately lead to weight gain," says Dr. Friedman.
Effects on food intake and body weight. Chronic PRL excess has been associated with increased food intake and weight gain, leading to obesity (6–10).
Prolactin contributes to hundreds of physiologic functions, but the two primary responsibilities are milk production and the development of mammary glands within breast tissues.
Cabergoline is taken twice a week and has fewer side effects than bromocriptine. Generally, cabergoline drops prolactin levels to normal faster than bromocriptine does. Cabergoline can cause heart valve problems when taken in high doses, but these doses are not used in women or men who are trying to get pregnant.
The specific expression of this aggressive behavior during early lactation occurs at a time when the levels of prolactin are high, suggesting prolactin might be involved in regulating this behavior.
In females, prolactinoma can cause:
Some mothers lose weight when they stop breastfeeding while others gain weight, but both are normal and healthy. Another factor is your hormones. When you stop breastfeeding, your body stops producing the hormone “prolactin” which promotes milk production.
Rule #2: The Breast Milk Storage Guidelines.
The 4-4-4 Rule. Or the 6-6-6 rule. Basically, breast milk is good at room temperature for 4 or 6 hours, in the refrigerator for 4 or 6 days, and in the freezer for 4 or 6 or 12 months. Different professional organizations have varying recommendations.
The production of prolactin can also inhibit the hormones that are responsible for ovulation, so you may notice that you don't get your period if you're exclusively breastfeeding.
High prolactin levels promote food intake, weight gain, leptin resistance and the insulin resistant state seen in pregnancy which allows glucose to be diverted to the developing fetus (1, 7–11).
A third hormone to consider is prolactin that helps with milk production and stimulating a mother's hunger. It may in some cases suppress the ability to metabolize fat, sometimes called the “fat-storing” hormone for this reason.
Most cases of hyperprolactinemia are caused by increased prolactin secretion from the pituitary gland, which also produces many other hormones that travel throughout the body. In women, physical or psychological stress, pregnancy and nipple stimulation have all been found to increase prolactin levels.
