Sneaky Causes of Fluid Retention
You’re watching your salt and taking your meds, so why are you still swelling? Here’s what else might be at play.

Swelling in the feet, legs, or abdomen can be a sign of fluid retention, a common symptom of heart failure. But even if you’re following your care plan, there may be other things contributing to the problem.
Hidden triggers may include:
- “Healthy” convenience foods like canned soups, frozen meals, or deli meat — often high in sodium
- Over-the-counter meds, especially NSAIDs like ibuprofen
- Weather changes, especially hot, humid days
- Inconsistent medication use or skipped doses
What to do:
- Read labels carefully and look for low-sodium options
- Ask your doctor about safer pain relief options
- Weigh yourself daily, as small changes can be an early warning sign
- Write down your symptoms so you can track patterns and share with your care team
If you notice swelling that’s new or worsening, check in with your provider. A few simple changes may help you feel better and avoid more serious complications.
