Periodical cramping

Ever missed school, work or a party because of a period? If you have like me, you have probably experience period cramps at the start of your period. For most of us, these cramps can be pretty severe.

Dysmenorrhea is severe menstrual cramping pain that occurs before and during a period, and includes symptoms like nausea, vomiting, diarrhoea and headache. People with dysmenorrhea often miss school or work, can’t participate in their normal daily activities and might experience poor mood and sleep during their period.

Dysmenorrhea usually starts at the beginning of a period, or right before a period, in the late luteal phase, and can last for the first few days of a period. It is reported by up to 90% of people with periods (1, 2), and is particularly high in adolescents (3, 4). It doesn’t usually appear until at least 6 months after menarche (1, 2). There are two types of dysmenorrhea – primary and secondary. Primary Dysmenorrhea has no secondary underlying condition whereas secondary dysmenorrhea has an underlying condition, such as endometriosis or adenomyosis.

The pain is usually described as fist opening and closing, in the lower back and lower stomach (2).

The main cause of Primary Dysmenorrhea is an increased amount of prostaglandins, a group of hormones, that are secreted from the endometrium during menstruation (1, 2, 4). Prostaglandins cause the uterus to contract, which also can limit blood flow in the uterus, causing pain in the lower back and lower stomach (1). For people with dysmenorrhea, the uterus contracts more severely and for longer periods than for those who don’t experience it (2). Prostaglandins can also cause the gastrointestinal tract to contract, causing the nausea, vomiting and diarrhea (1, 2, 5).

Diagnosis of dysmenorrhea is usually based on someone’s history of period pain (2), so it can be helpful to track your period pain, as well as what helps you to manage the pain. For this you can use a period-tracking app like Clue, or keep a journal, noting your period days, cramping, any medications as well as what helps and what doesn’t.

Dysmenorrhea can vary between people, and it doesn’t always prevent someone from going about their normal life. If you’re in severe pain that anti-inflammatories doesn’t relieve, your cramping lasts more than a few days, you’re bleeding more than what’s normal for you, or something feels wrong, please see a doctor.

Current treatment options are non-steroidal anti-inflammatory drugs (NSAIDs), like ibuprofen and aspirin, since these types of drugs prevent the production of prostaglandins in the uterus and can help reduce menstrual blood flow (1, 2). If this is an option for you, it’s recommended to use anti-inflammatories with food 1-2 days before menstruation begins to help tackle pain (1). Anti-inflammatory drugs don’t always work in people with dysmenorrhea, with one in four people experiencing little to no relief (4). They also can have severe side effects when used long term (6, 7), and might not be preferred by all people.

If you’re not currently trying to get pregnant, hormonal contraceptives are another option for treatment. Some oral contraceptives prevent ovulation, and so also prevent prostaglandins from being produced in the uterus (1, 8). These also have benefits if you also experience heavy menstrual bleeding (2). Hormone releasing IUDs like the Mirena have been shown to help relieve primary and some instances secondary dysmenorrhea (1, 9). If you’re wanting to use hormonal contraceptives to help with dysmenorrhea, it’s best to see a healthcare professional to help you select the right option for you.

Heat therapy, including hot water bottles, heat packs, wraps or patches placed on the lower stomach or back can help with period pain relief (2, 10). When applied, heat helps by increasing blood flow and this encourages the muscle to relax. Heat patches are a more portable option, and may help to support participation in normal life (11). Heat can be used with other treatment options, or by itself.

The addition of cinnamon, fennel and ginger to a diet has also been shown to reduce painful cramping (4).

Cinnamon has anti-inflammatory properties, limiting the production of prostaglandins (4, 12). It’s shown to have effects about 8 hours after consumption of 0.4-6g (6, 7, 13). Cinnamon has also been shown to reduce the duration of cramps (7). I’d recommend incorporating it into drinks like smoothies, on stewed fruit or baking it into cookies.

Fennel, more specifically fennel seed oil has also shown benefits by lessening uterus contractions (15). Some studies have shown similar relief of menstrual cramps from fennel seed oil to ibuprofen (15, 16). It does, however, have a strong taste (16), so I’d recommend taking it in a capsule.

Ginger has been shown to suppress the production of prostaglandins, and has pain relieving properties, showing similar effectiveness to ibuprofen for some people (4, 17). If you experience nausea, vomiting or bloating with your cramps, ginger can also help to relieve these symptoms (16).

Several studies have looked at the benefits of yoga for both primary and secondary dysmenorrhea, and as well the benefits of ginger for general health, stress, flexibility and muscle strength (9, 18, 19). Yoga combines breathing techniques, meditation and physical exercise. It’s thought that the benefits of yoga on stress and anxiety help alleviate the intensity of cramps, as well as play a role in activating the body’s natural painkiller, endorphins (9, 19). Some of my personal favourites for cramps include extended child’s pose (Utthita Balasana) and the cat/cow pose (Bidalasana).
