The menstrual cycle is a complex process regulated by a delicate hormonal balance that influences both the ovaries and the uterus. While many women experience mild symptoms, others face significant challenges, with conditions like endometriosis causing severe pain and discomfort. Despite existing treatments, such as hormonal therapies or surgical interventions, these options are often insufficient. Could CBD (cannabidiol) could fill the gap in menstrual health management? By examining the latest research and clinical trials, we aim to uncover whether CBD has the potential to relieve menstrual pain and improve overall quality of life.
?PHASES OF MENSTRUAL CYCLE
The menstrual cycle is a sophisticated process involving the brain, ovaries, and uterus, divided into two interconnected cycles: the ovarian cycle and the uterine cycle. Before ovulation, the cycle begins with the?menstrual phase?of the uterine cycle. This phase starts on the first day of your period and typically lasts 3 to 8 days. During this time, the uterus sheds its inner lining, resulting in menstrual bleeding. Estrogen and progesterone levels are at their lowest, signalling the body to release the old lining and reset for the next cycle. Following this is the?proliferative phase?of the uterine cycle, lasting until ovulation. In this phase, the uterus rapidly rebuilds its lining in preparation for a potential pregnancy, stimulated by rising estrogen levels that increase blood flow to the area. At the same time, the?follicular phase?of the ovarian cycle is happening. This phase starts at the beginning of the period and ends at ovulation, during which multiple follicles in the ovaries begin to mature. One dominant follicle grows larger than the others, preparing to release an egg. The pituitary gland produces follicle-stimulating hormone (FSH) to nurture these follicles, and the maturing dominant follicle produces increasing amounts of estrogen.
Around the middle of the cycle, ovulation occurs. This is known as the?ovulation phase?of the ovarian cycle and typically happens 13 to 15 days before the start of the next period. During ovulation, the dominant follicle releases a mature egg into the fallopian tube, ready for potential fertilisation. The process is triggered by a surge in luteinising hormone (LH) due to peak estrogen levels. After the egg is released, estrogen levels dip slightly, marking the transition to the next phase of the cycle.
After ovulation, the cycle enters the?secretory phase?of the uterine cycle, which lasts until the start of the next period. During this phase, the uterine lining thickens further and prepares to support a potential pregnancy. Glands within the lining secrete nourishing substances, creating an environment conducive to embryo implantation. Progesterone, produced by the corpus luteum (the remnants of the follicle that released the egg), rises significantly during this time, stabilising the lining. In the?luteal phase?of the ovarian cycle, the corpus luteum continues to produce progesterone and some estrogen to maintain the uterine lining. If fertilization does not occur, the corpus luteum breaks down after about 9 to 16 days, leading to a decline in progesterone and estrogen levels. This drop triggers the shedding of the uterine lining, and the menstrual cycle starts anew.
It is important to note that menstrual cycles vary from person to person and even from cycle to cycle. Factors such as stress, hormonal imbalances, age, and health conditions can influence the cycle’s length and symptoms. Understanding these phases and how they interact with hormonal changes can provide better insight into overall reproductive health, making it easier to track fertility, manage symptoms, and choose appropriate birth control methods.?
Why Do We Feel Menstrual Pain?
Menstrual pain, or dysmenorrhea, primarily occurs due to the body's natural processes during the menstrual cycle. The main cause is the contraction of the uterus as it works to shed its inner lining. This process is largely influenced by hormone-like substances called?prostaglandins, which play a critical role in regulating the intensity of these contractions.
At the start of menstruation, prostaglandin levels in the uterus increase. These chemicals prompt the uterine muscles to contract more intensely to help expel the uterine lining. The stronger the contractions, the more likely they are to compress blood vessels within the uterus, reducing blood flow and oxygen to the muscle tissue. This reduction in blood flow leads to a condition called?ischemia, which causes the muscles to produce pain signals that the brain perceives as cramping. Essentially, the uterus is undergoing a process similar to a muscle cramp but deep within the pelvic region.
In addition to prostaglandins, other inflammatory molecules are also released during this time, adding to the sensation of pain and discomfort. This inflammatory response can cause the pain to radiate to the lower back and thighs, and it may also lead to other symptoms like nausea, diarrhoea, and headaches. The severity of menstrual pain is closely linked to the amount of prostaglandins produced—higher levels typically result in more intense contractions and pain.
Hormonal changes further contribute to the pain. During the menstrual phase, levels of?estrogen?and?progesterone?drop significantly, triggering an increase in prostaglandins. This hormonal shift can also make the body more sensitive to pain signals, enhancing the perception of discomfort. In some cases, underlying health conditions like?endometriosis?or?uterine fibroids?can cause more severe menstrual pain, known as secondary dysmenorrhea. These conditions may lead to abnormal uterine contractions, inflammation, and tissue growth outside of the uterus, all of which can intensify pain.
How to Ease Menstrual Pain
Managing menstrual pain often requires a multifaceted approach. Heat therapy, like applying a heating pad to the lower abdomen, can relax the uterine muscles and improve blood flow, which reduces the strength and frequency of contractions. Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen are commonly used to alleviate pain by directly decreasing prostaglandin production, thereby lessening uterine contractions and inflammation. Lifestyle modifications also play a key role; regular exercise releases endorphins, acting as natural painkillers while enhancing blood circulation. A balanced diet rich in anti-inflammatory foods, such as fruits, vegetables, and omega-3 fatty acids, helps reduce overall inflammation. Staying hydrated and limiting caffeine intake can further ease bloating and muscle tension during menstruation.
This brings us to the question: could CBD bring relief to menstrual pain? In recent studies, CBD has emerged as a potential game-changer.
How has CBD been shown to help in menstrual cycle disorders
Ongoing clinical Trials:
?Three significant clinical trials are currently examining the role of CBD in managing pain associated with endometriosis, each involving distinct patient groups and trial phases.
The first trial, conducted by the?University of S?o Paulo?(DREAMLAND), is in phases 2 and 3 and focuses on women with chronic pelvic pain due to endometriosis who have already undergone hormonal treatments and surgery without satisfactory relief. The trial involves 102 women, all of whom are over 18 and continue to experience pain despite prior treatments. These participants are randomised into two groups: one receiving daily doses of CBD (starting at 10 mg and increasing to 150 mg) and the other receiving a placebo. Over a nine-week period, researchers will assess pain levels, psychological symptoms, and potential side effects to determine the effectiveness of CBD as a treatment for endometriosis-related pain
At?Penn State College of Medicine- Milton S. Hershey Medical Center, the second trial is in phase 3 and focuses on women aged 18-45 who have been surgically diagnosed with endometriosis. This trial targets patients with moderate to severe pain that has persisted despite prior treatment. The participants are divided into three groups: one receiving a placebo, another taking a low dose of CBD (10 mg), and a third receiving a high dose of CBD (20 mg), all alongside Norethindrone Acetate, a form of progesterone. The trial, involving 36 women, will assess changes in pain, sexual function, quality of life, and inflammatory markers over 12 weeks. This comprehensive approach aims to identify how CBD may affect multiple aspects of health for women suffering from endometriosis
The third trial, led by the?University of Edinburgh, involves 100 participants and is in phase 2. It focuses on women with chronic pain due to endometriosis who are receiving a specific CBD-based drug called MRX1. Supported by a ￡300,000 grant, this trial aims to compare MRX1 with a placebo to evaluate its effectiveness in reducing pain. Like the other trials, it also monitors psychological symptoms and side effects. If successful, this study could lead to a larger national trial to make MRX1 a mainstream treatment option within the NHS.
