If you suffer from period bloating, we 100% feel you. Really, we do. The swollen belly, the constant expelling of air from every orifice, the impossible task of getting off the sofa… it’s all pretty common at certain times during your cycle. But what’s actually going on in there? We’re doing a deep dive on all things bloating; the cause, the feels, the ways to reduce it. Let’s go...
One thing people commonly mix up is the difference between bloating and water retention. They are often used interchangeably, but are in fact two separate things that can both happen in the week before your period. Premenstrual water retention is typically caused by hormone fluctuations, and diet can also play a role. Bloating of the period variety can be caused by hormones, but it presents as a gaseous feeling of increased pressure in the abdomen, even if there isn’t actually anything in there.
Abdominal bloating can feel like your belly is full, or even swollen. It can feel tight, hard to the touch, and can be rather painful. You might also pass wind more than usual, frequently burp, or experience belly gurgles. For some people this will quickly pass and it won’t be an issue, while for others, it can interfere with daily life and cause them to avoid social situations. If this is the case for you, you should speak to your GP about it so they can provide possible remedies.
Bloating happens when your hormone levels change before your period begins, specifically the hormones progesterone and oestrogen. These changes can also cause the body to retain more water and salt, which adds to the feeling of bloating. According to one study, 85% of people report physical symptoms related to their period. This could be cramping, acne, fatigue and others, but it also includes bloating. Symptoms can change month to month and as you get older, so don’t worry that you’ll be bloated every month until the end of time - the bloat may disappear as quickly as it appeared!
Most people who menstruate can experience bloating one or two days before their period begins. For some, it starts as much as five days before, and can affect everyday activities. One study done in 2011 found that people whose bodies retained the most water experienced worse bloating on the first day of their period. Once you start your period, bloating tends to dissipate and you may find some relief.
Period bloating isn’t a nice feeling, so even if you know it’s going to disappear after your period comes, you may want to try a few tricks to lessen the impact. While you can’t always prevent bloating completely, there are some home remedies that can help:
