Menstrual cramps usually refer to a dull, throbbing, cramping pain in the lower abdomen, just above the pelvic bone.
Other symptoms may include:
pain in the lower back and thighs
nausea and vomiting
faintness and dizziness
diarrhea or loose stools
People should see a doctor if:
the symptoms are severe or get progressively worse
blood clots are bigger than a quarter
pain is present at other times, not just around menstruation
Menstruation usually happens approximately every 28 days between puberty and menopause, except during pregnancy. During menstruation, the muscles of the womb contract and relax in an irregular way. This motion helps the womb expel unwanted tissue and blood.
Everyone experiences these contractions, but some people do not notice them. For others, however, the discomfort can be severe. Some individuals may also experience nausea, vomiting, and other symptoms.
The hormone-like substances that trigger this process are called prostaglandins. Prostaglandins form in the lining of the uterus.
Factors that appear to reduce the risk of menstrual cramps include
having given birth more often
the use of birth control pills
A person is more likely to have severe cramps if they:
are experiencing stress
are aged under 30 years — especially before the age of 20 years
have heavy periods
have a family history of menstrual cramps
Other factors that may increase the likelihood include:
being a survivor of sexual abuse
Conditions that can worsen menstrual cramps
Several underlying medical conditions can also cause or worsen menstrual cramps.
some forms of birth control
pelvic inflammatory disease
If these cause severe symptoms, a person may need surgery.
Over-the-counter pain relievers are often effective in easing menstrual cramps. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, can often relieve the pain.
Manufacturers have created some products specifically for menstrual cramps. These combine NSAIDs and antiprostaglandins, and they can reduce cramping in the uterus, lighten the flow of blood, and relieve discomfort.
In some cases, a doctor may prescribe hormonal birth control pills to prevent ovulation and reduce the severity of menstrual cramps. These pills work by thinning the lining of the uterus, where the prostaglandins form, which can reduce cramping and bleeding.
Other types of hormonal birth control, including some intrauterine devices (IUDs), vaginal rings, patches, and injections can all help decrease cramping.
If the cramps are due to an underlying medical condition, such as endometriosis or fibroids, a doctor may recommend surgery to remove the unwanted tissue.
Some natural remedies that may provide relief are:
applying a heat pad to the lower abdomen
practicing relaxation and mindfulness techniques
engaging in physical exercise, such as jogging or yoga
taking a warm bath or shower
having a massage
using transcutaneous electrical nerve stimulation (TENS)
Various herbal teas and other herbal remedies may help manage symptoms, although research has not yet proven that they can help.
A 2019 review concluded that chamomile tea has antispasmodic, anti-inflammatory, sedative, and antianxiety properties that may make it useful in treating premenstrual syndrome (PMS), including cramps.
A small 2014 study found that people who took Pycnogenol, the registered trademark brand name for French maritime pine bark extract, for 3 months alongside birth control pills had less pain and fewer days of bleeding compared with those who used only birth control pills.
At least one small study has found that fennel extract may help reduce menstrual pain. Other research found that it did not reduce pain but that the severity of bleeding was less when people took fennel drops for up to two menstrual cycles.
Lavender and other essential oils may help reduce menstrual discomfort. In one study, half of the participants smelled a cloth scented with lavender for the first 3 days of their period over two menstrual cycles. These individuals experienced less severe pain than those who used a placebo.
The authors of a 2018 review concluded that lavender and rose oils might have moderate benefits.
A 2016 review suggests that oral ginger may help reduce menstrual pain.
There is not enough evidence to prove that any of these remedies work, but they are unlikely to be harmful if a person uses them under supervision.
The Food and Drug Administration (FDA) do not regulate herbs and supplements for quality or purity. Therefore, it is best to check with a doctor before using any herbs or supplements, as they can sometimes have adverse effects.
Menstrual cramps are a common problem that occurs around the time of the monthly period. Various remedies can help manage the pain and discomfort that they can cause.
If the symptoms are severe or occur at other times in the month, it is a good idea to see a doctor.
