What brought you here

Swelling in your legs, ankles, or face

Shoes that fit in the morning and not by three o'clock. A ring that won't come off. Puffiness around your eyes when you wake up. Swelling has several possible causes, and your kidneys are one of the common ones.

What swelling has to do with your kidneys

One of your kidneys' main jobs is deciding how much salt and water to keep and how much to send out. When they aren't clearing sodium as well as they used to, the extra fluid stays in your body — and gravity pulls it downward, into your ankles and lower legs. That's why the swelling is often worse at the end of the day and better after a night's sleep.

Puffiness around the eyes tends to have a different cause. If your kidneys are leaking protein into your urine, the protein level in your blood drops, and fluid seeps out of your blood vessels into the surrounding tissue. That kind of swelling often shows up in the face first, in the morning.

It isn't always the kidneys

Swelling is one of those signs that several organs share. The heart, the liver, the veins in your legs, an underactive thyroid, and a number of common medications — including some blood pressure pills — can all cause it. Pregnancy and long days on your feet cause it too.

Sorting out which one is happening is a large part of what a first visit is for. It is not something you can settle by reading, and you shouldn't try to.

Don't wait on these

Most swelling can wait for a regular appointment. These can't:

  • Shortness of breath, or needing to sit up to breathe comfortably at night — call 911.
  • Chest pain along with the swelling — call 911.
  • Swelling in one leg only, especially with pain, warmth, or redness — this needs to be looked at the same day.
  • Gaining more than two or three pounds in a day or two, or five pounds in a week.

What happens next

What a first visit looks like

  1. We check your blood pressure and weight, and look at where the swelling actually sits.
  2. Blood and urine tests tell us how well your kidneys are filtering and whether protein is leaking.
  3. We go through your full medication list — including anything over the counter — because a few common ones cause ankle swelling on their own.
  4. We work out whether this is coming from your kidneys, your heart, your liver, or your veins, and we tell you which in plain language.
  5. You leave with a plan: what to change, what to watch for at home, and when we'll see you again.

Questions people ask us about this

How do I know if my swelling is from my kidneys or my heart?

You can't tell from the swelling alone — they look very similar, and sometimes both are involved. The difference shows up in blood work, urine tests, and an exam. That's exactly the question a first visit is built to answer, so bring it with you.

Will cutting back on salt make the swelling go down?

Often it helps, sometimes a lot. But how much salt to cut, and whether fluid should be limited too, depends on why you're swelling and what medications you take — and for some causes, cutting fluid is the wrong move. Get the cause sorted first, then the plan is straightforward.

Do I need my doctor to send me, or can I just call?

Call us either way at (559) 661-1965. Many insurance plans do want a referral from your primary care doctor before seeing a specialist, and our staff will check your plan's requirements with you on the phone. If you already have recent lab work, bring it.
