How is fluid overload diagnosed?
A number of conditions produce signs and symptoms that resemble fluid overload, and these need to be excluded. These conditions include:
- Lung problems, such as blood clots, infections, asthma.
- Heart problems, such as inflammation of the covering of the heart (pericarditis).
- Problems with the venous circulation or lymphatic circulation.
- Disorders causing a low protein level in the blood (hypoproteinaemia).
- Liver disease.
- Thyroid disease.
Will I need any tests?
It's not surprising that with all these conditions to rule out you will need several tests. These may include:
- Heart tests: heart tracing (electrocardiogram, or ECG) and ultrasound scanning of the heart (echocardiogram, or echo).
- Chest X-ray.
- Blood tests to check your kidney function, blood count, liver function, blood gases.
- A special test for heart failure, called B-type natriuretic peptide (BNP).
- Charts to check how much you drink and pee and any weight changes in response to treatment.
What are the treatment options for fluid overload?
The treatment depends on your symptoms.
See separate leaflet on the treatment of sudden-onset (acute) fluid overload of the lungs, called Pulmonary Oedema. There is also more information available on heart failure treatment. See separate leaflet called Heart Failure.
What is the outlook for fluid overload?
This depends on the underlying cause and how well you were before the fluid overload occurred. For example, if the fluid overload was due to a problem with your heart, the outlook (prognosis) depends on how treatable your heart condition is. If the fluid overload resulted from being given too much fluid during intravenous treatment, the outlook will depend on the reason why you needed intravenous fluid in the first place. If you were given it because you had just had a simple operation but were well beforehand, the outlook should be good once the overload is corrected. However, if intravenous treatment was given because you had a serious problem such as extensive burns, correcting the overload may be more complicated.
