Swelling (edema) is a build-up of water in the tissues. Common
causes include salt and water retention (due to medicines or heart,
liver, or kidney failure), poor nutrition, pelvic tumors, or blockage
in the veins or lymph system. Fluid can also build up in the abdomen.
This is known as ascites (as-SIGH-tees). It makes the belly look
swollen.
What to look for
- Feet and lower legs get larger when you sit in a chair,
stand, or walk
- Rings feel too tight for fingers
- Hands feel tight when making a fist
- Large, puffy, or blown-up abdomen (belly)
- Trouble breathing, especially when lying down (See the
section on shortness
of breath.)
- Heart racing or palpitations (or an awareness that the
heart beat is fast or irregular)
What the patient can do
- Limit your use of salt on food. Avoid use of table salt and
salt in cooking, and don't eat foods that are very high in salt.
- Talk with the doctor about how to reduce your salt intake.
- Eat as well as you can. (See the section on poor
appetite.)
- Take medicines as prescribed by the doctor.
- Rest in bed with your feet up on 2 pillows.
- When sitting up in chair, keep your feet level with your
chest by placing them on a stool with pillows.
What caregivers can do
- Watch for any new symptoms, especially shortness of breath
or swelling in the face.
- Encourage the patient to keep the swollen body part propped
up as high as is comfortable when sitting or lying down.
- Don't add salt, soy sauce, or monosodium glutamate during
cooking.
- Weigh the patient every day or 2 on the same scale, at the
same time of day. Keep a list of weights and dates.

- Can't eat for a day or more
- Hasn't urinated, or has urinated very little, for a day or
more
- Can press a finger into a swollen area and the fingertip
mark remains
