As Taraneh Shirazian, MD, a gynaecologist at NYU Langone Health, explained in an interview with Popsugar, PMS symptoms are a side effect that results from the surge of a hormone called LH, while also experiencing a decline in the hormone progesterone. So, should you be feeling nauseous or perhaps experiencing diarrhoea, don’t stress. Rather than assume the worst, it might just indicate that your period is coming. When you should be a little more concerned is if the nausea is severe, worsening or continues after the onset of your period. If your period is late, it could also be a sign of early pregnancy in which case a pregnancy test is recommended.
Though symptoms of PMS tend to disappear once your period begins, nausea can be particularly unpleasant to deal with and make daily activities very difficult. If you’re someone who falls into this category, there are some things you can do to minimise the discomfort. Avoid foods that are triggering, and consume mint and ginger which tend to be extremely helpful when it comes to nausea.
As Dr Shirazian told Popsugar, “I think if you’re very symptomatic around PMS and your period, you definitely should talk to your physician about possibly using something hormonal [bireth control] to level the hormones so that your body doesn’t notice the natural flux of the LH surge and the progesterone withdrawal.”
