Should I weigh myself regularly, and when is weight gain something to worry about?
Heart failure can cause your body to hold extra fluid. This makes your weight go up. Fluid often builds up in the legs, ankles, and belly.
Heart failure means your heart cannot pump blood well. Blood slows and backs up, and fluid leaks into your body tissues. This causes swelling—called edema—and weight gain. Fluid most often collects in the ankles, lower legs, and belly. It can also build up in and around the lungs, making breathing harder.
Weight gain from fluid tends to happen faster than usual weight gain. Tracking your weight can help you notice fluid buildup early.
Your care team may recommend eating less sodium and drinking less fluid. These are common steps to help control fluid buildup. Ask your care team which weight changes need attention and when to reach out.
