Bloating and Swimming During Perimenopause
Does swimming help with perimenopause bloating? Find out how water-based exercise reduces bloating and makes exercise more comfortable on difficult days.
Bloating During Perimenopause
Bloating is one of the more uncomfortable and demoralising symptoms of perimenopause, and it often catches women off guard. Unlike the bloating associated with a large meal, perimenopausal bloating tends to be more persistent and harder to attribute to any single cause. Fluctuating levels of oestrogen and progesterone affect fluid balance, gut motility, and the gut microbiome, all of which can produce a feeling of abdominal fullness or puffiness that varies day to day. For many women, bloating is worst in the lead-up to a period and gradually becomes more unpredictable as cycles become irregular. Exercise including swimming can meaningfully reduce its frequency and severity.
Why Swimming Is Particularly Good for Bloating
Swimming has several features that make it especially well suited to managing perimenopausal bloating. The hydrostatic pressure of water applies a gentle, even compression to the body, which encourages fluid redistribution away from the periphery and abdomen. This physical effect can provide temporary but noticeable relief from the puffiness of water retention bloating. Swimming is also a full-body aerobic workout that stimulates gut motility, helping gas and fluid move through the digestive tract more efficiently. The rhythmic, whole-body movement of swimming also triggers the relaxation response, which reduces the cortisol-driven inflammation that can worsen perimenopausal gut symptoms.
The Comfort of Water Exercise
One of the reasons many perimenopausal women find swimming particularly appealing is that the buoyancy of water removes the discomfort of gravity-loaded exercise. On days when bloating makes wearing tight clothing or performing high-impact movements feel unbearable, the pool offers a kinder alternative. The water supports your body weight, reducing pressure on a tender or distended abdomen. Swimwear, while form-fitting, does not compress the waist in the same way that elasticated waistbands do. For women who dread the feeling of their clothing pressing into a bloated belly during a workout, swimming sidesteps that issue almost entirely.
Strokes and Session Structure
All major swimming strokes provide aerobic and circulatory benefits that support bloating management, so choosing a stroke comes down to personal preference and comfort. Freestyle and backstroke involve rhythmic rotation of the torso, which can help stimulate gut movement. Breaststroke is gentler and well suited to days when you want to exercise without overexerting. Backstroke is particularly comfortable during abdominal bloating because the face-up position removes any downward pressure on the belly. A session of 30 to 45 minutes at a comfortable, conversational pace is sufficient to achieve the circulatory and gut-motility benefits without exhausting yourself.
Hydration and the Pool
Swimming can create a false sense of not needing water because the cool environment masks sweating, but swimmers do lose fluid and electrolytes during a session. Adequate hydration is important for managing bloating because dehydration causes the body to retain water more aggressively, worsening the puffiness. Drink water before, during, and after your swim. If you are swimming for longer than 45 minutes or in a heated pool where you notice more sweating, electrolyte replacement may also be helpful. Plain water with a small amount of added electrolytes is a simple option that supports both performance and fluid balance.
What to Avoid Around Swimming Sessions
Certain habits around your swim can make bloating worse rather than better. Eating a large meal high in fermentable carbohydrates, such as beans, lentils, or cruciferous vegetables, immediately before swimming can create significant abdominal discomfort in the water. A light, easily digestible snack 60 to 90 minutes before the pool is a better approach. Swallowing air during freestyle breathing, which some swimmers do inadvertently, can also add to the feeling of bloating mid-session. A swim coach or technique video can help correct breathing mechanics if this is an issue. Avoiding alcohol and carbonated drinks in the hours before swimming also supports a more comfortable experience.
Making Swimming a Consistent Part of Your Routine
The benefits of swimming for perimenopausal bloating compound over time with consistent practice. Aiming for two to three swim sessions per week provides enough aerobic stimulus to improve gut function, reduce inflammation, and support the hormonal environment that influences fluid retention. Many women find that scheduling their swim for the same time each week makes it easier to maintain. If access to a pool is limited, water aerobics classes offer many of the same benefits in a social, guided format. Logging your workouts alongside symptom data in PeriPlan helps you see whether swimming is reducing the frequency or severity of your bloating, keeping you motivated to continue.
