Does Progesterone Oil Cause Weight Gain?

Progesterone hormone therapy is a standard treatment for low progesterone. One common question is whether progesterone oil causes weight gain. The quick answer is that fluctuating hormone levels do cause various symptoms, including weight gain. However, evidence shows that progesterone supplementation may cause you to add a few pounds, but it also may help you lose them. In this article, we'll dive into the intricacies of progesterone oil and look at whether it does or doesn't encourage weight gain. 

How the Body Produces Progesterone 


Progesterone is a sex hormone produced primarily by the corpus luteum in the ovaries during the second half of a woman's cycle. The placenta generates progesterone levels during pregnancy to help sustain a healthy fetus. 


Healthy progesterone levels regulate a woman's menstrual cycle and prepare the embryo for fertilization. It works in conjunction with another sex hormone, estrogen. Low progesterone can result in the following conditions or symptoms. 


  • Decreased fertility
  • Menstrual irregularities
  • Miscarriage and early labor
  • Bloating
  • Weight gain 
  • Mood changes
  • Hot flashes

During a woman's childbearing years, progesterone levels fluctuate but remain normal unless there's a medical issue. But as they grow older and become perimenopausal, menopausal, and postmenopausal, levels can plummet along with estrogen to result in significant bodily changes. 

Primary Reasons for Progesterone Supplementation


The question of progesterone and weight gain first came about because of the everyday use of birth control pills and hormone therapy. Contraceptive pills commonly have estrogen and progesterone in them, but the mini-pill will only have progestin or progesterone. Progestin is the synthetic form of progesterone. The effect of progesterone on the body as a birth control pill makes you "think" you're pregnant already and prevents your body from creating an egg. The mini-pill is most commonly used when a woman is breastfeeding since it doesn’t affect the milk production. 


In hormone therapy, you take progesterone usually to help with fertility or as menopausal treatment. Menopause means your menstruation "pauses forever" and results in the loss of the ability to have a baby. All women transition from fertile to infertile. To help combat the symptoms of menopause, women have different options. 

Bioidentical Progesterone vs. Synthetic Progesterone


Progesterone hormone replacement therapy comes in two forms: bioidentical and synthetic. Bioidentical progesterone is a natural form that mimics the exact progesterone produced in your body. It's usually derived from wild yams or soy. Synthetic progesterone isn't plant-based or natural but usually comes from equine or horse urine. 


The debate over which is more effective depends on who you ask and what research you quote. But overall, wouldn't you take something completely natural and mimic your body's hormones rather than ones that don't?

Progesterone's Role in Weight 


Weight regulation involves complex interactions within our bodies, extending far beyond the simplistic view of calories in versus calories out. Similarly, progesterone's role in weight is multifaceted. Increased progesterone levels can influence weight by contributing to weight gain through various mechanisms. 


The metabolic effects of progesterone, combined with its hormonal interactions, can lead to an increase in appetite and changes in how fat cells function and store fat. Additionally, progesterone is known to cause water retention, further complicating its impact on weight. Understanding these dynamics is crucial for managing weight effectively, highlighting how hormonal balance plays a key role in overall weight regulation.

The Debate: Weight Gain or Loss 


Weight changes can result from several factors, from eating too much to hormonal fluctuations. Whether progesterone causes weight gain is complex and, unfortunately, has no easy answer. Progesterone, in particular, has been linked to unexplained weight gain due to its ability to cause some water retention. 


On the other hand, progesterone can cause weight loss in others by affecting blood sugar levels and metabolism, illustrating the hormone's dual impact on the body. The changeability reveals how progesterone's influence can lead to weight gain in certain situations, emphasizing the need for a nuanced understanding of hormonal effects on weight.

Factors Influencing Weight Gain with Progesterone 


Several elements can influence weight gain when considering the role of progesterone in the body's hormonal balance. When progesterone levels are too low, it can lead to a state where excessive estrogen dominates, a condition often referred to as estrogen dominance. This imbalance can contribute to weight gain, as estrogen promotes the storage of fat. 


Additionally, when the body becomes insulin resistant, it struggles to efficiently use sugar from the blood for energy, leading to weight gain. This resistance can be exacerbated by hormonal imbalances, including those involving progesterone. 


Another factor to consider is the state of one's gut health in overall weight management. An imbalance in the gut biome can affect the body's metabolic processes and hormone regulation, including how progesterone is used. Together, these factors illustrate how delicate the balance of hormones is in weight management and the complex role progesterone plays within it.

Managing Weight While Using Progesterone Oil 


Progesterone supplements, used in conjunction with a balanced diet and exercise, usually help with weight loss. Progesterone therapy helps balance hormones, leading to a better ability to process sugar correctly and store less fat. BIOLabs Progesterone Oil is 100% natural and infused with MCT oil to help your body come back into balance naturally. 


Progesterone has minimal side effects, but consult your doctor before taking any supplement. Monitoring progesterone levels while undergoing hormone therapy will also help you determine the correct dose for your body. 

Key Takeaways

The question of whether progesterone oil contributes to weight gain is crucial for individuals seeking a balanced hormone therapy approach. Hormonal imbalances can lead to weight gain, positioning progesterone oil as a potentially effective treatment. 


Menopausal women often experience low levels of estrogen and progesterone, and supplementing with these hormones can aid in overall well-being and potentially stop weight gain. However, it's important to note that progesterone may cause water retention, resulting in weight fluctuations. 


This underscores the importance of seeking healthcare advice and undergoing lab testing to determine if progesterone oil is a suitable option. For many, it is indeed a beneficial choice.
