The symptoms of heart failure can be related to the pooling of fluid in the body or can be secondary to decreased blood flow to the body. Some people with heart failure don't experience symptoms, but here are some of the more common signs:
Shortness of breath with exercise or difficulty breathing at rest or when lying down
Swollen legs, ankles, or abdomen
Dry, hacking cough, or wheezing
Other symptoms may include:
Fatigue, palpitations, or pain during normal activities
Follow the label directions on how often to take your diuretic. If you are taking a single dose a day, take it in the morning with your breakfast or right afterwards. If you are taking more than one dose a day, take the last dose no later than 4 p.m.
The number of doses you take each day, the time allowed between doses, and how long you need to take the medication will depend on the type of diuretic prescribed, as well as your condition.
Dizziness, lightheadedness: Try rising more slowly when getting up from a lying or sitting position.
Blurred vision, confusion, headache, increased perspiration (sweating), restlessness: If these effects persist or are severe, contact your doctor.
Dehydration: Signs include dizziness, extreme thirst, excessive dryness of the mouth, decreased urine output, dark-colored urine, or constipation. If these symptoms occur, don't assume you need more fluids. Call your doctor right away.
