Approximately 85 percent of women who menstruate experience at least one PMS symptom, explains the American Congress of Obstetricians and Gynecologists. Some of these women will experience PMS so severe that it will interfere with their ability to function at work or at home. Lifestyle changes, supplements and medications can provide relief so women will no longer feel hindered by their PMS symptoms.
Lifestyle Changes
Many lifestyle changes lessen PMS symptoms. Dietary changes that might help include eating complex carbohydrates, fiber and protein and avoiding sugars, fat, salt, caffeine and alcohol. Eating smaller but more frequent meals can also help. Women may also find that keeping a regular schedule, taking a multivitamin supplement daily, getting plenty of sleep and exercise and avoiding stressful events right before a menstrual period proves beneficial.
Calcium
Calcium supplements can reduce symptoms of cramps, water retention and back pain, according to the American Academy of Family Physicians, or AAFP. Although women should talk to their doctor before taking any supplements, the AAFP states that taking about 1,000 milligrams of calcium daily shouldn't be harmful. It also may provide other benefits besides relieving certain PMS symptoms, such as strengthening bones and teeth.
Relaxation Techniques
Women with severe PMS may find relief through relaxation techniques, according to the American Congress of Obstetricians and Gynecologists. Although the specific technique is a matter of personal preference, common relaxation techniques include deep breathing exercises, visualization, progressive muscle relaxation, meditation, yoga and massage therapy.
Birth Control Pills
Birth control pills ease PMS symptoms by evening out hormone levels throughout the menstrual cycle. Women interested in taking birth control pills should talk to their doctor about the benefits and risks of doing so before deciding if it is the right choice for them.
Diuretics
Diuretics, also referred to as water pills, can reduce the swelling, bloating and weight gain associated with PMS. These pills help a woman's body shed excess water through the kidneys. Prescription diuretics, however, can cause unwelcome side effects. All women should talk to a doctor before taking any diuretic medications for their PMS symptoms.
Over-the-Counter Medications
While most over-the-counter PMS medications are most useful for mild or moderate PMS, they also may help severe cases in some circumstances. These medications typically consist of a combination of acetaminophen or aspirin with caffeine, diuretics or antihistamines. Pain relievers, including ibuprofen and naproxen, relieve cramps and other aches caused by severe PMS.
Antidepressants
Many women with severe PMS suffer from irritability, anxiety and depression. Antidepressant medications can lessen these symptoms. Women interested in antidepressant medication should talk to a doctor or mental health professional to explore their medication options.
