When you’re going through fertility treatment, the focus is usually on follicles, meds, and monitoring not sodium. But if you’ve ever experienced ovarian bloating or been told you might have OHSS (Ovarian Hyperstimulation Syndrome), understanding the right way to handle sodium and fluids can make a world of difference in how you feel.
💧 What’s Really Happening in OHSS
During OHSS, the ovaries become enlarged and leaky and fluid moves from your blood vessels into your abdomen and tissues. That fluid shift makes you look and feel bloated, but inside, your blood volume and sodium levels actually drop.
This is why many people feel lightheaded, weak, or dehydrated, even when their belly feels full of fluid. It’s a confusing mix because your body is both swollen and dehydrated at the same time.
🧂 Why Cutting Sodium Can Backfire
It’s common to hear “avoid salt to prevent bloating,” but in OHSS, that advice can actually make things worse.
Sodium helps your body keep fluid inside the blood vessels which maintains blood pressure, circulation, and kidney function.
If you restrict salt and drink tons of plain water, you can dilute your sodium even further (a condition called hyponatremia). That can make you feel dizzy, nauseated, or fatigued and it can prolong recovery.
⚖️ The Right Balance
Instead of going “low-sodium,” focus on balanced electrolytes.
Here’s what that looks like:
Sip electrolyte-rich fluids: coconut water, bone broth, or electrolyte mixes
Include natural sources of sodium and protein: eggs, broth-based soups, salmon, lean meats, cottage cheese.
My favorite salt to use is Redmond Unrefined Mineral Salt due to is higher micronutrient content.
Avoid plain water overload, aim for steady sipping, not constant chugging.
Skip overly processed salty foods (chips, ramen, etc.) that add sodium without hydration value.
🩺 When to Reach Out
If you experience rapid weight gain, abdominal swelling, shortness of breath, or decreased urination, contact your fertility team immediately.
These can be signs of moderate to severe OHSS that need medical monitoring or IV fluids.
🌸 The Takeaway
Your body isn’t failing you. It’s reacting strongly to fertility medications. Giving it the right support (including smart sodium and hydration choices) helps it find its balance again. You don’t need to fear salt, you just need to pair it with protein and hydration so your body feels safe and supported while it heals.
🧠 Bonus Tip:
OHSS recovery is not just about “waiting it out” it’s about stabilizing your vascular system. So if you’re prepping for a cycle and want to stay ahead, ask your nurse or doctor about your OHSS risk and what electrolyte strategy they recommend before your trigger shot.
